• RHEL - blocked FC remote port time out: saving binding

  - by Dev G

  My Server went into a faulty state since the database could not write on the partition. I found out that the partition went into Read Only mode. Finally to fix it, I had to do a hard reboot.

• Understanding Linux SCSI queue depths

  - by Troels Arvin

  I'm experimenting with the effects of different SCSI queue depth values on a Dell server running CentOS Linux 5.4 (x86_64). The server has two QLogic QLE2560 FC HBAs connected via multipathing to a storage system. The storage system has allocated two LUNs to the server, each connected through four paths in an active-active-active-active round-robin configuration. All in all, the two LUNs exist as eight /dev/sdX devices, represented by two devices in /dev/mpath. I currently adjust the queue depth values in /etc/modprobe.conf and check the result (after rebooting) by looking in the seventh column of /proc/scsi/sg/devices. Two questions related to that: Is there a way to adjust queue depths without rebooting or unloading the qla2xxx kernel module? E.g., can I echo a new queue depth value into some /proc or /sys-like file to update the queue depth? If I set the queue depth to 128, is that 128 in total for all devices handled by the qla2xxx module?, or 128 for each HBA? (256 in total), or 128 for each of the eight /dev/sdX devices (1024 in toal)?, or 128 for each of the two /dev/mpath/... devices (256 in total)? This is important for me to know so that my server doesn't flood the storage system, affecting other servers connected to it.

• Can I have different ESX hosts accessing the same LUN over different protocols?

  - by Kevin Kuphal

  I currently have a cluster of two ESX 3.5U2 servers connected directly via FiberChannel to a NetApp 3020 cluster. These hosts mount four VMFS LUNs for virtual machine storage. Currently these LUNs are only made available via our FiberChannel initator in the Netapp configuration If I were to add an ESXi host to the cluster for internal IT use can I: Make the same VMFS LUNs available via the iSCSI initiator on the Netapp Connect this ESXi host to those LUNs via iSCSI Do all of this while the existing two ESX hosts are connected to those LUNs via FiberChannel Does anyone have experience with this type of mixed protocol environment, specifically with Netapp?

• How to block some disks from probes on Linux boot?

  - by Igor Velkov

  My linux host connected to SAN with FC interface. It connect with one path, and see some luns, that can't access, because they need anohter path, not available to host. On boot linux probe all lun he can see, get read error on unaccessible luns, and hangs there for a long-long time. Is there a way to disable any access to some luns at boot time, and later? I found a filters for device ignoration for LVM and MULTIPATH, but it not help during boot process. Generally, lvm still affected too despite of filter, and gives me a IO error on every operation like lvdisplay and vgdisplay, but this is another question.

• Alpha plugin in GStreamer not working

  - by Miguel Escriva

  Hi! I'm trying to compose two videos, and I'm using the alpha plug-in to make the white color transparent. To test the alpha plug-in I'm creating the pipeline with gst-launch. The first test I done was: gst-launch videotestsrc pattern=smpte75 \ ! alpha method=custom target-r=255 target-g=255 target-b=255 angle=10 \ ! videomixer name=mixer ! ffmpegcolorspace ! autovideosink \ videotestsrc pattern=snow ! mixer. and it works great! Then I created two videos with those lines: gst-launch videotestsrc pattern=snow ! ffmpegcolorspace ! theoraenc ! oggmux ! filesink location=snow.ogv gst-launch videotestsrc pattern=smpte75 ! ffmpegcolorspace ! theoraenc ! oggmux ! filesink location=bars75.ogv And changed the videotestsrc to a filesrc and it continues working gst-launch filesrc location=bars75.ogv ! decodebin2 \ ! alpha method=custom target-r=255 target-g=255 target-b=255 angle=10 \ ! videomixer name=mixer ! ffmpegcolorspace ! autovideosink \ filesrc location=snow.ogv ! decodebin2 ! alpha ! mixer. But, when I use the ideo I want to compose, I'm not able to make the white color transparent gst-launch filesrc location=video.ogv ! decodebin2 \ ! alpha method=custom target-r=255 target-g=255 target-b=255 angle=10 \ ! videomixer name=mixer ! ffmpegcolorspace ! autovideosink \ filesrc location=snow.ogv ! decodebin2 ! alpha ! mixer. Can you help me? Any idea what is happening? I'm using GStreamer 0.10.28 You can download the test videos from here: http://polimedia.upv.es/pub/gst/gst.zip Thanks in advance, Miguel Escriva

• SAN newbie: What kind of fiber cables do I need to connect to the front end ports on my EMC CX300

  - by red888

  I have an old CX300 I'm messing with and I cant determine what kind of HBA\fiber cables I need to connect a server to the front end ports on the DPE2. The hardware reference doesn't give me any details and being new to FC-SAN all of the options are pretty overwhelming. I don't know if the ports are SC or LC or if it requires singlemode or multimode. Googling hasn't turned up anything for me either. All I know is that it supports 2GB Fiber. Here is a pic of one the modules. You can clearly see the front-end ports (FE)

• Merit and demerits for various Linux fiberchannel multipath options

  - by wzzrd

  On our Linux servers, we currently use HPs qla2xxx drivers, because it has multipathing (active/passive) built in. The are, however, various other options, like Red Hats device-mapper-multipath with the stock qla2xxx drivers (multibus and failover) and things like SecurePath and PowerPath (both of which can do trunking, iirc). Can someone tell me what the merits and demerits of the various options are (if I can ask such a question), besides the obvious fact that the {Secure,Power}Path options cost vast amounts of money? I'm mainly interested in the freely available options, like HPs qla2xxx vs. Red Hats multipathd and possible other open source solutions, but I would like to hear good reasons to go for the commercial solutions too. UPDATE: I'll be benchmarking various options the coming few days (the average of 10 runs of iozone for each option (options being native qla2xxx failver, native qla2xxx multibus, HP qla2xxx failover)). I'll post a summary of results here for those interested.

• Cisco FC SAN switch decision

  - by Chopper3

  I've got to buy a bunch of FC SAN switches in the next week or so, I have to, and want to, buy Cisco MDSs. Servers are HP BL490c G6's in C7000 chassis with Virtual-Connect Flex-10 ethernet interconnects and VC FC interconnects (Emulex HBAs btw), all running ESX 3.5U4 (for now). I think I've only really got two choices; MDS 9509's with dual-supervisors with a single 48-port 4Gb FC card MDS 9222i's with single supervisor and the built-in 18-FC-port/4-GigE-FCIP-port option Both have the same functionality (I think, buying the enterprise licence btw), both have plenty enough performance and adequate ports for now and the next three years. The 9222i's are about 55% the price of the 9509's - logic says get the 'i's but will I really miss the dual-supervisors? I've got lots of 9509's with dual-supervisors that I'm very happy with but I'm not sure I've every benefitted from the dual-sups in the past and they are nearly twice the price - but if I don't buy them and miss them I can't retrofit them later. What are your thoughts?

• Diagnosing SAN connectivity issues (RHEL5)

  - by Matthew

  We are currently utilizing GFS2 to share a SAN LUN between 3 servers. However due to a feature problem with vendor software we are using, we currently have the volume unmounted on two of the boxes, and are instead exporting the GFS2 filesystem via NFS from the first one (the software requires some weird locking mechanics that GFS2 doesn't support). As of this morning, NFS was no longer able to read/write to the volume from any of the servers, including the NFS server. I then tried checking the normal mount (the directory that is exported on the NFS server) and I received a weird input/output error just trying to CD into it. When I tried running multipath, I got a DM error, however multipath -l worked just fine. I tried unmounting the GFS2 volume, and the CLI hung. I ran init 0 which killed most services, but then the shutdown appeared to have been hung. I logged in via out of band access (hp ILO) and saw that the shutdown was hung trying to unmount GFS2 volumes. My main priority was getting the box back online so after about 5 minutes of waiting I did a hard reset. I am now trying to figure out what went wrong. What are the correct logs to investigate? I've never run into SAN issues like this before. The SAN is connected via 2 fibre connections. Any help would really be appreciated. Everything appears to be up and functional now.

• SAN cache memory upgrade

  - by Scott Lundberg

  We currently have an IBM DS4300 Dual Controller Fibre SAN. It is a good box, but getting pretty old. It came with 256MB of cache per controller. Recently we replaced the batteries in one of the controllers and noticed that the cache is a DDR PC2100 ECC DIMM. Of course, we are thinking about how cheap this RAM is now and is there any good reason we can't upgrade the RAM. IBM used to have a "Turbo" upgrade to this box that doubled the cache and had a bunch of software features for about 10K USD. Since that product has been end-of-lifed, I don't think we can get that upgrade and we don't need the software upgrades (FlashCopy, StorageCopy, etc). Besides the obvious potential warranty issue, what if any issues would we expect to see if attempting to put 2 - 1GB DIMMS in this unit? Any other things I am missing here? EDIT: Memory label: Samsung CN 0433 PC2100U-25331-A1 M381L3223ETM-CB0 256MB DDR PC2100 CL2.5 ECC

• Are FC and SAS DAS devices standard enough?

  - by user222182

  Before I ask my questions, here is some background info that may or may not be useful: For the first time I find myself needing a DAS solution. My priority is data through-put in a single direction. I can write large blocks, and I don't need to read at the same time. The server (the data producing device) is not really a typical server, its a very powerful single board computer. As such I have limited options when it comes to the add-in cards I can install since it must use the fairly uncommon interface, XMC. Currently I believe I am limited PCIex8 gen 1 which means that the likely bottle neck for me will be this 16gbps connection. XMC Boards I have found so far offer the following connections: a) Dual 10GBE ethernet controller, total throughput 20gbps b) Dual Quad SAS 2.0 Connectors (SFF-8XXX) HBA (no raid), total throughput 48 gbps c) Dual FC 8gb HBA (no raid), total throughput 16gbps My questions for you guys are: 1) Are SAS and/or FC, and by extension their HBAs, standard enough that I could purchase a Dell or Aberdeen storage server with a raid controller that has external SAS or FC ports and expect that I can connect it to my SAS or FC HBA, be presented with a single volume (if I so configured the storage server), all without having to check for HBA compatibility? 2) On a device like a Dell PowerVault (either DAS or NAS) is there an OS on it to concern myself with, or is it meant to be remotely managed? Is there a local interface in case I cant remotely manage it (i.e. if my single board computer uses an OS not supported by Dell OpenManage). Would this be true of nearly any device which calls itself a DAS? 3) If I purchase some sort of Supermicro storage chassis, installed a raid controller with external connections, is there a nice lightweight OS I can run just for management of the controller? Would I even need an OS since the raid card would be configured pre-boot anyway? 4) It is much easier to buy XMC based 10gigabit ethernet cards (generally dual port). In what ways would I be getting into trouble by using iSCSI as a DAS are direct cabling with SFP+ cables? Thanks in advance

• Which events specifically cause Windows 2008 to mark a SAN volume offline?

  - by Jeremy

  I am searching for specific criteria/events that will cause Windows 2008 to mark a SAN volume as offline in disk management, even though it is connected to that SAN volume via FC or iSCSI. Microsoft states that "A dynamic disk may become Offline if it is corrupted or intermittently unavailable. A dynamic disk may also become Offline if you attempt to import a foreign (dynamic) disk and the import fails. An error icon appears on the Offline disk. Only dynamic disks display the Missing or Offline status." I am specifically wondering if, on the SAN, changing the path to the disk (such as the disk being presented to the host via a different iSCSI target IQN or a different LUN #) would cause a volume to be offlined in disk management. Thanks! Edit: I have already found two reasons why a disk might be set offline, disk signature collisions and the SAN disk policy. Bounty would be awarded to someone who can find further documented reasons related to changes in the volume's path. Disk signature collisions: http://blogs.technet.com/b/markrussinovich/archive/2011/11/08/3463572.aspx SAN disk policy: http://jeffwouters.nl/index.php/2011/06/disk-offline-with-error-the-disk-is-offline-because-of-a-policy-set-by-an-administrator/

• Sea Monkey Sales & Marketing, and what does that have to do with ERP?

  - by user709270

  Tier One Defined By Lyle Ekdahl, Oracle JD Edwards Group Vice President and General Manager  I recently became aware of the latest Sea Monkey Sales & Marketing tactic. Wait now, what is Sea Monkey Sales & Marketing and what does that have to do with ERP? Well if you grew up in USA during the 50’s, 60’s and maybe a bit in the early 70’s there was a unifying media of culture known as the comic book. I was a big Iron Man fan. I always liked the troubled hero aspect of Tony Start and hey he was a technologist. This is going somewhere, just hold on. Of course comic books like most media contained advertisements. Ninety pound weakling transformed by Charles Atlas in just 15 minutes per day. Baby Ruth, Juicy Fruit Gum and all assortments of Hostess goodies were on display. The best ad was for the “Amazing Live Sea-Monkeys – The real live fun-pets you grow yourself!” These ads set the standard for exaggeration and half-truth; “…they love attention…so eager to please, they can even be trained…” The cartoon picture on the ad is of a family of royal looking sea creatures – daddy, mommy, son and little sis – sea monkey? There was a disclaimer at the bottom in fine print, “Caricatures shown not intended to depict Artemia.” Ok what ten years old knows what the heck artemia is? Well you grow up fast once you’ve been separated from your buck twenty five plus postage just to discover that it is brine shrimp. Really dumb brine shrimp that don’t take commands or do tricks. Unfortunately the technology industry is full of sea monkey sales and marketing. Yes believe it or not in some cases there is subterfuge and obfuscation used to secure contracts. Hey I get it; the picture on the box might not be the actual size. Make up what you want about your product, but here is what I don’t like, could you leave out the obvious falsity when it comes to my product, especially the negative stuff. So here is the latest one – “Oracle’s JD Edwards is NOT tier one”. Really? Definition please! Well a whole host of googleable and reputable sources confirm that a tier one vendor is large, well known, and enjoys national and international recognition. Let me see large, so thousands of customers? Oh and part of the world’s largest business software and hardware corporation? Check and check JD Edwards has that and that. Well known, enjoying national and international recognition? Oracle’s JD Edwards EnterpriseOne is available in 21 languages and is directly localized in 33 countries that support some of the world’s largest multinationals and many midsized domestic market companies. Something on the order of half the JD Edwards customer base is outside North America. My passport is on its third insert after 2 years and not from vacations. So if you don’t mind I am going to mark national and international recognition in the got it column. So what else is there? Well let me offer a few criteria. Longevity – The JD Edwards products benefit from 35+ years of intellectual property development; through booms, busts, mergers and acquisitions, we are still here Vision & innovation – JD Edwards is the first full suite ERP to run on the iPad as just one example Proven track record of execution – Since becoming part of Oracle, JD Edwards has released to the market over 20 deliverables including major release, point releases, new apps modules, tool releases, integrations…. Solid, focused functionality with a flexible, interoperable, extensible underlying architecture – JD Edwards offers solid core ERP with specialty modules for verticals all delivered on a well defined independent tools layer that helps enable you to scale your business without an ERP reimplementation A continuation plan – Oracle’s JD Edwards offers our customers a 6 year roadmap as well as interoperability with Oracle’s next generation of applications Oh I almost forgot that the expert sources agree on one additional thing, tier one may be a preferred vendor that offers product and services to you with appealing value. You should check out the TCO studies of JD Edwards. I think you will see what the thousands of customers that rely on these products to run their businesses enjoy – that is the tier one solution with the lowest TCO. Oh and if you get an offer to buy an ERP for no license charge, remember the picture on the box might not be the actual size.

• Mapping of memory addresses to physical modules in Windows XP

  - by Josef Grahn

  I plan to run 32-bit Windows XP on a workstation with dual processors, based on Intel's Nehalem microarchitecture, and triple channel RAM. Even though XP is limited to 4 GB of RAM, my understanding is that it will function with more than 4 GB installed, but will only expose 4 GB (or slightly less). My question is: Assuming that 6 GB of RAM is installed in six 1 GB modules, which physical 4 GB will Windows actually map into its address space? In particular: Will it use all six 1 GB modules, taking advantage of all memory channels? (My guess is yes, and that the mapping to individual modules within a group happens in hardware.) Will it map 2 GB of address space to each of the two NUMA nodes (as each processor has it's own memory interface), or will one processor get fast access to 3 GB of RAM, while the other only has 1 GB? Thanks!

• WCF client proxy initialization

  - by 123Developer

  I am consuming a WCF service and created its proxy using the VS 2008 service reference. I am looking for the best pattern to call WCF service method Should I create the client proxy instance every time I call the service method and close the client as soon as I am done with that? When I profiled my client application, I could see that it is taking lot of time to get the Channel while initializing the proxy client Should I use a Singleton pattern for the client proxy so that I can use the only once instance and get rid of the re-initializing overhead? Is there any hidden problem with this approach? I am using .Net framework 3.5 SP1, basicHttp binding with little customization.

• chrooting user causes "connection closed" message when using sftp

  - by George Reith

  First off I am a linux newbie so please don't assume much knowledge. I am using CentOS 5.8 (final) and using OpenSSH version 5.8p1. I have made a user playwithbits and I am attempting to chroot them to the directory home/nginx/domains/playwithbits/public I am using the following match statement in my sshd_config file: Match group web-root-locked ChrootDirectory /home/nginx/domains/%u/public X11Forwarding no AllowTcpForwarding no ForceCommand /usr/libexec/openssh/sftp-server # id playwithbits returns: uid=504(playwithbits) gid=504(playwithbits) groups=504(playwithbits),507(web-root-locked) I have changed the user's home directory to: home/nginx/domains/playwithbits/public Now when I attempt to sftp in with this user I instantly get the message: connection closed Does anyone know what I am doing wrong? Edit: Following advice from @Dennis Williamson I have connected in debug mode (I think... correct me if I'm wrong). I have made a bit of progress by using chmod to set permissions recursively of all files in the directly to 700.
