    mksysb on NIM

    make sure your mount point for the nfs directory has correct permissions. To do that, unmount the filesystem and then check the permissions on the mount point.

    AIX5L and EMC SAN disks

    you can't run sdd and powerpath together on the same machine. well...let's put it this way. you MIGHT, if you write your own code, get it to work. But you will not get support for it from either EMC or IBM. you have to install one or the other, not both. That means uninstalling SDD if you're...

    IBM Support Question

    Hardware support has nothing to do with your operating system. If your contract for your hardware is good, you'll get hardware support. Be aware: If the hardware tech determines you need software assistance for the problem, even though you opened the call as a hardware call, you will be asked...

    AIX v4.3.3 vs. 5.1 & 5.2

    You have to make sure first, that your applications will run on the new version of AIX that you are migrating to. And if they will not, you have to aquire the upgrade software for them. You'll have to go to the application vendors to find out if they'll run on the version of aix you want to...

    Learning HACMP

    -run this type of command while your processes are up but no -application activity is happening. which would make it impossible to run it on a system with a normal HACMP set up, because you need the filesystems to be mounted. YOu need that, because you need to see if hacmp is going to be able...

    Learning HACMP

    the only supported method of testing hacmp is to do a graceful shutdown with fail over. Yes, the pont of hacmp is fault tollerance, but realisticaly, it's very rare that a machine would suddenly lose power as it does when you yank the cord from the wall. Even if your entire data center was to...

    Learning HACMP

    it's essential to have good scripting knowledge, but NOT for hacmp. The hacmp scripts and other files are written by IBM and maintained by IBM. However, you as Admin need to write the scripts to start up, shut down and do other things to your application and database. All HACMP does is call...

    Learning HACMP

    -Delay Part: Does the application have to support HACMP, or -is this done all at the OS level? Also, how does the -application know where the system went down? How does it -pick up from that? HACMP is a set of scripts that runs on top of the OS and pretends to be you. What happens is this. When...

    VI/O server : adding new disk to a vritual LPAR need help

    yeah, probably a good idea to just remirror the entire vg whether it's on a vio server or not.

    Learning HACMP

    Yes. You can set them up so that node 1 and 2 both fail over to node 3, and node 3 fails over to either 1 or 2 (which ever you prefer) or doesn't fail over at all, just sits there and waits for one of the others to fail. You can do that with 4, 5 and so on nodes. However at some point you're...

    Heart-beat using hdiskhb

    Yes you need a disk solely for this, but the disk does NOT have to be part of a resource group.

    Learning HACMP

    -Can someone please explain the concepts basic concept: Your users never notice when your machine is down, because another machine takes over processing their data Basicaly, you have one machine running your applicaton, and if it crashes or has to be taken down, you have a second machine...

    ld: 0711-317 ERROR: Undefined symbol

    looks like a licence problem. Read through the following information. you'll see your errors at the very bottom: LUM - Quick Install of Concurrent Nodelocked License in AIX 4 and 5 This document applies to AIX Versions 4 and 5. It describes how to quickly install a concurrent nodelocked...

    Bull fibre driver

    That driver doesn't actualy exist. AIX assignes that name when it knows it needs a driver but doesn't know what it's called. You'll need to contact the manufacturer of the card and ask them where to get the driver for your version of AIX>

    How do i wipe out rootvg?

    There are disk wiping utilities but they don't usualy do a very good job. Formatting isn't guarenteed to remove everything either. BUt if you format the disk then do an overwrite install of AIX to the disk, then format again, that should be secure enough.

    FSCK problem : Logredo failed

    The jfs log does, yes, have information about the filesystem...if nothing other than the filesystem it's going to be the log FOR. you run FSCK if you can't mount the filesystem. If you can mount it and the only error you get is that the log failed, not superblock problems or something simular...

    exportvg

    a: You can't reimport the vg's if you didn't export them. Not sure why hirscha said not to export but to import in his reply. From the redbook: Will my machine run the 64-bit kernel? 64-bit hardware is required to run the 64-bit kernel. For AIX 5.2, all IBM eServer pSeries 64-bit hardware...
