  • Setting Boot and Mirror Disks correctly at the Solaris OBP

    - by Shaun Dewberry
    I am recovering a domain that was lost due to power outage on an Sun Fire E25K server. I know how to set the appropriate parameters at the openboot prompt using nvalias/devalias, boot etc. However, I do not understand how one gets from the output of show-disks {1a0} ok show-disks a) /pci@1dd,600000/SUNW,qlc@1/fp@0,0/disk b) /pci@1dd,700000/SUNW,qlc@1/fp@0,0/disk c) /pci@1dc,700000/pci@1/pci@1/scsi@2,1/disk d) /pci@1dc,700000/pci@1/pci@1/scsi@2/disk e) /pci@1bd,600000/SUNW,qlc@1/fp@0,0/disk f) /pci@1bd,700000/SUNW,qlc@1/fp@0,0/disk g) /pci@1bc,700000/pci@1/pci@1/scsi@2,1/disk h) /pci@1bc,700000/pci@1/pci@1/scsi@2/disk q) NO SELECTION Enter Selection, q to quit: to the correct full disk path. I know it is basically one of the pci/scsi paths listed above, but in all instruction or examples a string of additional characters is appended to the path to specify Targets and Units but the explanation of the path construction is never given. Could someone please explain how to construct this disk path correctly?

  • Asus V1S screen dimming randomly

    - by Bill
    I have an Asus V1V, which is the same as the Asus V1S except for the video card. I have a problem where the screen will randomly lose brightness or flicker between being lit and not lit. The picture below is of the left hinge, with the cover removed. Pressing one of these cables affects this behaviour, and pressing it in place will resolve the issue for a few hours. My guess means the inverter cable is damaged, based on previous experience. As the picture shows, there are two cables, an LCD cable and what I assume is an inverter cable. I purchased an LCD cable for my model of laptop, but have been unable to find an inverter cable. It seems not to exist. I would like some input on if an inverter cable actually exists, if it is likely the problem, or solutions in general to resolve this problem permanently.

  • Which type of memory is faster than average for server use?

    - by Tony_Henrich
    I am building a server computer which will be used for SQL Server and I am planning to use like 32G+ of RAM and putting the databases in memory. (I know all about data loss issues when power is gone). I haven't been up to date with the new types of memory sticks out there. What kind of memory should I get which is faster than average and not very expensive? I am buying a lot of ram so I am looking for memory that's above average but below high end if high end is very expensive. (I will be using Windows Server 2008 R2 Standard or Windows HPC Server 2008 R2)

  • How many bootable partitions are possible to have on one hard drive?

    - by draiden
    This may not be the correct place to post this; if that's the case, just let me know and point me in the right direction please! I'm thinking of building a box that needs to be lightweight and portable, and would need to be able to boot multiple installations of windows. I am needing to have multiple installations so that I can, for example, plug the box in to the network at one location, boot in to that location's partition, and have full access to everything I would normally need to do on a computer that has already been set up on that network. Then, when I go to the next client, I would be able to do the same thing, with the new location's partition, and have all of those network settings, drive mappings, etc., available there. Obviously I'd need to go through and set them all up on the different locations/networks, I'm not expecting it to magically know where I am and what I'm doing. It would be like I'm carrying around a computer that is configured for each place I need to go in one little box, instead of having to have multiple computers or having to reconfigure all the settings and such every time I go to another client. Or is there an easier way to do this that I haven't learned of?

  • How to see all nics in Solaris 8/9

    - by help_me
    I have a questions regarding how to see all NICS in the solaris 8/9 SPARC boxes. Even if they are active/inactive. dladm show-link command does not work. cat /etc/path_to_inst could but it's hard to make out the NICS. Also when a cable is disconnected from the NIC ifconfig -a still shows the NIC as "UP/RUNNING" without looking at the system message, is there a way to know that the NIC is unplugged? Thank you!

  • Multi mouse, keyboard and monitors

    - by Click Ok
    I've got a USB hub with 4 ports, and I've plugged 2 usb keyboards and 2 usb mouses. They work very fine. I've setup'ed 2 monitors too, so I was thinking about the possibility of the mouse and keyboards works independent one of another. I want two mouse pointers (I think each with different colors) and 2 keyboard cursors. I think it a nice idea, but I don't know if this is possible... :( PS: My OS is Windows7

  • SQL Server: Network pauses after installing cheap SATA card: Is there a solution?

    - by samsmith
    At the risk of being assigned to the "bad DBA" club... I did something desperate, and may have to undo it. Problem: After installing a low cost eSATA board, my SQL Server is intermittently unresponsive (seemingly when there is a lot of IO to the eSATA drive). Questions: 1) Is there a solution to the intermittent unresponsiveness that allows me to keep the eSATA in place? 2) Whether or not (1==true): What is a decent, low cost way to add 1-3 TB storage to SQL for non-critical SQL DBs? Detail: Our SAN is full, and expanding it is costly and will take a month. I have a pressing need to add 1-3 TB for some development DBs (e.g. not mission critical; data loss is OK). As a bandaid, I threw a $20 eSATA PCI board in the Dell 1950 server, and attached an external 2TB eSATA drive. This seemed to work fine, but I notice that our production SQL DBs, and even remote desktop, now experience network "pauses" that they never did before (with both SQL client apps and remote desktop throwing "networking problem" errors). This SQL Server has lots of memory, and runs an instance of SQL 2005 (where all line of business apps reside) and an instance SQL 2008 (for development db's). SQL Server RAM has been appropriately configured, and this setup has run great for years. The server is: Dell 1950 Win2003 x64 14GB RAM PERC controller, 2 mirrored hd's internal Dell SAN over gbit ethernet, dual homed 2 PCIx slots (1 used by NIC for SAN, 1 now in use for eSATA board) Thank you for suggestions!

  • I don't have a free PCI / PCI-e slot, can it be worked around?

    - by Borek
    I need to add a PCI(e) card to a nettop PC that is so small that the card won't fit there (and there is no external alternative like we're used to with external TV tuners). The only ports available are USB and eSATA, is it possible to somehow "dock" the PCI card into some device that would then connect to the PC via USB or eSATA? Or am I out of luck? (I don't mind the solution being visually ugly, I wouldn't even mind opening up the case and soldering some wires in, anything that would work would be great.)

  • I suspect that my HDD is causing hardlocks, as all other components have been replaced. How can I check this theory and solve the potential cause?

    - by user867814
    I have had this problem over quite a while now, thorough multiple Linux kernel versions and distributions, as well as replacement of all components, aside from my main HDD - RAM, GPU(twice), mother board, CPU, power supply. What happens is, at one point during the operation of the PC, it will hardlock - everything stops working, external HDD is not shut down correctly and continues to spin until I plug it out and in, there are no system/kernel logs of any kind, and no otherwise nothing that would suggest a cause. Another reason for my suspicion is that the failures happen almost exclusively during HDD read/write activity - shutdown(happens nearly 1/3 of the time so far, it's only been few days though), launching programs, and once during operation of apt. I hope the post is descriptive enough, if you need any additional info, ask(and tell me how to prepare/obtain it), and I will provide. If I'm wrong, point me in the right direction. Thanks in advance.

  • Find the model of my motherboard without opening the computer [closed]

    - by Code
    Possible Duplicate: Find out what the motherboard on my computer is I need to find the model of my motherboard so I can find what soundcard/chip it uses so I can get some drivers for it. Is there anyway to get this from inside XP? I looked through device manager but haven't seen anything that would tell me. I built the system over a year ago and don't have any receipts to check what it was.

  • Why does the heat production increase as the clockrate of a CPU increases?

    - by Nils
    This is probably a bit off-topic, but the whole multi-core debate got me thinking. It's much easier to produce two cores (in one package) then speeding up one core by a factor of two. Why exactly is this? I googled a bit, but found mostly very imprecise answers from over clocking boards which do not explain the underlying Physics. The voltage seems to have the most impact (quadratic), but do I need to run a CPU at higher voltage if I want a faster clock rate? Also I like to know why exactly (and how much) heat a semiconductor circuit produces when it runs at a certain clock speed.

  • How do I find a bigger battery for my laptop?

    - by KeyStroke
    Hi, I have an ASUS K42JR laptop, and the battery life in this thing sucks (2 hours max). I'd like to get a bigger battery for it, and I've found a bunch online, but I have no idea which one fits/works with my laptop. Any idea how I can find that out? and which site do you recommend I buy it from? Your help is much appreciated

  • Why does using 2 memory sticks cause my computer to crash?

    - by hi
    My computer randomly crashes when playing games, but if I remove one memory stick (it does not matter which one I remove), it does not crash anymore. Memory tests do not find errors, I just put in a new power supply (650W), I only have 1 graphics card, so why is this happening? BTW, they are the same memory, same vendor same specs, everything I bought it together (2x2GB) My motherboard is a Asus P5Q Pro, so it supports both dual channel and more than 4gb. Switching slots does nothing, as long as I don't use more than 1 I'm fine.

  • Low end dedicated GPU vs. integrated Intel graphics (for light CAD work)

    - by PaulJ
    I have been asked to spec a PC for an interior design business. They are going to do some AutoCAD work (but they won't be using massive datasets or anything), and also use Kitchen Draw, a program that has 3D visualization features and says, in its requirements, that "a recent NVidia or ATI card might be enough". Since they are very limited budget-wise, I had originally picked a GeForce GT 610 card, but this card is so low end that I'm left wondering whether it will be an improvement at all over the dedicated Intel HD2500 graphics chip that comes with the CPU (I will be using an Ivy-Bridge Intel i5). Most of the information I see around is for gaming, which isn't really relevant in my case. Basically, for the use case I've described (light 3D work), can one get away with a current Intel HD graphics chipset? And will a low end GPU like the GT 610 provide a noticeable improvement?

  • Tool to test HDD for health?

    - by Ognjen
    I've had my HDD replaced, and now my computer is freezing every 1 to 5 minutes for 5 to 10 seconds. Actually, only active applications freeze (but it can be ANY application), usually when I click something, but sometimes by themselves. How can I check if this is HDD issue or software issue? I don't want to send my laptop for second HDD replacement right away, since the last service took 40 days, so I am looking for a tool that could confirm that this is a HDD issue.

  • Fixing bent pins on a CPU

    - by Pekka
    While replacing a mainboard in a desktop machine (see related question), I did something stupid. I inserted the CPU into the new mainboard, but didn't check for the right position. When it didn't immediately lock in, I pressed slightly before realizing what was wrong. The result was a number of bent pins. I tried every tutorial that popped up when Googling "CPU bent pins" - using credit cards, sewing needles, and a hunting knife to get the pins back into position - but to no avail: For every pin I get straightened out, two others are bent. I have no problem getting individual pins straightened out, but my many attempts have led to many pins being slightly askew - enough for the CPU not to fit into the socket (An AMD X3 one). Maybe I just lack the motoric finesse. What I would need is some sort of a grid to fix all pins at once. It's a €50 processor so the loss is not catastrophic. But I thought before I go buy a new one, I thought I'd check here whether anybody knows some magic trick, or a cheap generally-available tool to fix this.
