  • EMC ESRS stops working when it is VMotioned

    - by makerofthings7
    EMC is on site and told me: The ESRS SAN monitoring solution will cease to function if that host is VMotioned In case anyone doesn't know, the ESRS is a dial home solution that works over IP. An EMC SecureID is required to add or modify the list of devices that are monitored. The ESRS software is installed on the customer premises. Question If ESRS truly fails to work, as the EMC engineer stated, and based on our customer experience, what is it within VMWare that is exposed to the virtualized host that allows this behavior to happen?

  • Setting Linux UID on NFS volume from EMC NX4

    - by ethrbunny
    I have an EMC NX4 from which there are several CIFS shares with corresponding NFS mount points. The CIFS user ids seem fine but when viewed from Linux they are all 327xx numbers and can't be set from the file system. (IE CHOWN doesn't work - permission denied). On our other (older) EMC devices we used an MMC app to set the Linux UID for each user. I don't seem to have such an app on the 'Applications and Tools' CD for this new device. Is there some other method for setting these? Did I setup the system incorrectly?

  • Link rate between EMC DAE and HBA

    - by Johan Christensson
    I have a EMC DAE (KTN-STL4) drive cage directly connecconnected to a HP Proliant server using a QLogic QLE2560 HBA. I'm using copper cable between the HBA card and the DAE. On the controller card in the DAE there is a label that states "4Gb". I'm guessing that this means 4Gbit/s. But if I set the HBA card to "Auto speed" it negotiate 2Gbit/s, and if I hard set it to 4Gbit/s I end up with no link. Why is this? Isn't the DAE controller card capebel of link speed higher then 2Gbit/s or is it the copper cable that limits the speed, or is it the interface used between the DAE and Qlogic HBA that is the problem? I have been browsing for HSSDC-FC converters and they always seems to på rated at ~2Gbit/s. If this is the limit, why does it say 4Gb on the controller cards in the DAE?

  • Dell EqualLogic vs. EMC VNXe [closed]

    - by Untalented
    We've been looking into SMB SANs and based on the competitive pricing I've been getting we're really liking these two array's. There are some pro's to both solutions, but I've unable to really decide which to choose. The EMC offers better expandability since you can buy an additional shelf (roughly $1200) and can add drives then to the array. However, the Dell unit is still very nice. Can anyone comment on their experiences with the two and thoughts on this? Also, to get the VMware Storage API support you need VMware Enterprise. How much additional performance does this provide? It's roughly $15k more than the Essentials Plus bundle we're looking at (this is a small environment [3 Hosts 1 Array].

  • solaris + EMC + power-path

    - by yael
    please advice - when I run powercf command on my Solaris machine , which changes this command do on the EMC storage , or on Solaris file system ? from maanual page: DESCRIPTION During system boot on Solaris hosts, the powercf utility configures PowerPath devices by scanning the HBAs for both single-ported and multiported storage system logical dev- ices. (A multiported logical device shows up on two or more HBAs with the same storage system subsystem/device identity. The identity comes from the serial number for the logical device.) For each storage system logical device found in the scan of the HBAs, powercf creates a corresponding emcpower device entry in the emcp.conf file, and it saves a primary path and an alternate primary path to that device.

  • EMC VNX iSCSI setup - unsure about SP/port assignment

    - by pauska
    We have a new VNX5300 waiting to get configured, and I need to plan out the network infrastructure before the EMC tech arrives. It has 4x1gbit iSCSI per SP (8 ports in total), and I'd like to get the most out of the performance until we jump over to 10gig iSCSI. From what I can read from the docs - the recommendation is to use only two ports per SP, with 1 active and 1 passive. Why is this? It seems kind of pointless to have quad-port i/o-modules and then recommend to not use more than two of them? Also - I'm a bit unsure about the zoning. The best practices guide state that you should separate each port on each SP from each other on different logical networks. Does this mean that I have to create 4 logical networks to be able to use all 8 ports? It also gives the following example: Does this mean that A0 and B0 should sit on the same physical switch aswell? Won't this make all traffic go on one switch (if both A1 and B1 are passive)? Edit: Another brainpuzzle I don't get it - each host (as in server) should not have more iSCSI bandwidth available than the storage processor. What on earth does this matter? If serverA have 1gbit and serverB have 100mbit, then the resulting bandwith between them is 100mbit. How can this result in some kind of oversubscription? Edit4: Wait, what. Active and passive ports? The VNX runs in a ALUA configuration with asymmetrical active/active.. there shouldn't be any passive ports, only preferred ones..

  • Resizing an iscsi LUN on an EMC under Linux RHEL 5

    - by niXar
    I expanded a LUN on my SAN (from 30G to 50G), and tried all kind of voodoo but it looks like the system still believes the device is still small, despite showing me the new size alright. # blockdev --getsize64 /dev/sdl 53687091200 # dd if=/dev/sdl skip=$(( 31*1024*1024*1024/512 )) count=1|hexdump -C dd: reading `/dev/sdl': Input/output error The dd line works for blocks below the 30G original size. If I reboot, the problem goes away, but I don't want to since the machine has a dozen VMs running. I tried various magic, such as: iscsiadm -m node -R -I iface0 ... to no avail. Note: I'm not using multipath.

  • Linux not picking up new partition correctly on emc pseudo device

    - by James
    Hi We have a database server running oracle rac. We were recently running out of space on the main LUN that it is attached to. I created a new 100GB LUN and concatenated this onto the existing LUN creating a new MetaLUN. After some messing I managed to get linux to recognise the new space. I then created a new partition in on the pseudo device, to use the new space. Previously when I have done this on other system the next step is to create an ASM disk on the new partition and add this disk to the oracle disk group. This however fails. I am aware of various issues with ASM and powerpath, but I don't think this is the issue here. As on while investigating the issue I discovered that one of the underlying logical device is not reflecting the size change. See below; Powermt displays all of the underlying logical units [root@XXXXX~]# powermt display dev=emcpowerd Pseudo name=emcpowerd CLARiiON ID=CKM00091500009 [VFRAC2] Logical device ID=6006016030312200787502866C65DE11 [LUN 30] state=alive; policy=CLAROpt; priority=0; queued-IOs=0 Owner: default=SP A, current=SP A Array failover mode: 1 ============================================================================== ---------------- Host --------------- - Stor - -- I/O Path - -- Stats --- ### HW Path I/O Paths Interf.

  • EMC CX3-10c Fault Condition won;t clear

    - by ITGuy24
    We have an old CX3-10c from Dell that had both Standby Power Supplies (SPS) fail. This obviously caused a fault on the system and disabled the cache. We have replaced the SPS's and they test fine as do all other components. Problem is there is still a fault on the "Enclosure SPE [SPE3]" despite all the component in the enclosure showing as good. I was on the line with Dell Gold support for 3 hours yesterday, they have had me restart the SPs multiple times, as well as reseat the power supplies, even shutdown the system completely and power it back on. All to no avail. Fault remains and cache cannot be re-enabled so long as the Fault is present. Any suggestions on clearing this erroneous fault?

  • Can you set CIFS permisions from EMC Command Line?

    - by TJ.
    I am in the process of migrating file shares from my EMC NS-20 to my new VNXe 3100. I am using a RoboCopy script to move the files but am getting errors on some files and folders. I have Domain Admin privileges but when I go to view the security permissions on the folders it says I don't have permissions. I have tried taking ownership to get around the permissions issue but that fails too. So as a last resort can I set permissions on this folder from the EMC console or Web management console?
