Disk Move

When I try to move a set of disks from old P690 to another different
P690, is it just a case of removing the disks after exportvg and then
importvg on the new system ?

I also want to understand from the hardware perspective, if the disks
are simply taken out from old frame and fitted into the new P690
frame. Any other precautions from Software an hardware front ?

Ciao.

Hi Ciao,

I'm sure you are trying to move the SCSI disks. You don't require to
do anything other than exportvg and importvg.

Just follow the steps
1) unmount all the filesystems and varyoff the volume group.
2) exportvg the volume group.
3) Remove the disks from the system using rmdev.
4) Remove the disk physically and add it to the other system.
5) Run a cfgmgr in the new system, and just do a importvg.
6) varyon the volume group and start mounting the filesystems.

Everything should be fine.

Regards
LeO

I think doing a backup before ripping out the drives would not hurt :-)

Type of VG may matter. Example: Source system runs AIX 5.3 and
the VG is an SVG. Destination system runs 5.2....
There were new features added to LVM over time - if the destination
system has a lower AIX level than the source, make sure this supports
the type of VG and the features.

Move Hard Disk Drives Between p630 and p615
We are in the process of setting up a loaner p630 server running AIX 5.1 while waiting on a p615 server to arrive. Since a number of application installation steps have to be done (database, application, etc.) as well as changes to configuration files will need to be made to the boxes, there is some concern about the amount of work to move from the p630 to the p615 once it arrives. One of the suggestions that has been brought forth is that we should be able to shutdown the boxes, remove the drives from the p630, install them into the p615, and then restart the p615 as it was configured on th...

Tru64 Unix 5.1b-4 moving advfs root to new disk
Scenario -- ES40, 2 x Adaptec U160 39160, 400GB scsi-to-ide array on one pair of ports (pka/pkc) and brand new 3TB array on the other pair. Moved all data to new array. Went to boot and root won't mount. I disklabeled correctly (disklabel -wr -t advfs /dev/rdisk/dsk4c) and made a domain (root_domain) and fs (root) and have tried copying data various ways. Booting from cdrom will mount the new root as a proper advfs fs. Booting from old root will mount it also. When I boot it directly, it gets to the point of bringing up advfs and doing the root mount and it now says, "...

labeling a disk on AIX 5L / disk cmds
Hi folks ! I have got two question about disk operations: (01) Is there a separate cmd to explictly label a disk ? I don't mean assigning a user defined string, but rather creating a kind of signature / partition information as is done under Solaris with the format cmd. (02) I need to perform all kinds of disk operations: - detect new disk devices - create disk devices - label disk devices - partition disks While I find great command line support for the aforementioned ops, I have was not able to find a good resource for C API calls.

VMware
Hello -- I am running VMware version 4.5. It is currently running off of a Maxtor 20GB HD. I'm in the process of a system upgrade, and my main system disk will become 2x Western Digital Raptors (RAID0 or RAID1, havent decided yet). I wish to free up a drive bay by moving VMware to a virtual disk, stored on my main system disk array. Is there a tool that can create a VMware-readable disk image from a physical disk?

My experience is if they don't go away from properly formatted ipcs / ipcrm commands, it's because they're tied to processes which are hung waiting on kernel threads (and basically, defunct). In which case you need to kill the owning process (which is already dead, and which probably won't respond to a kill -9 since it's stuck in a kernel thread) or reboot the box. SAP is the worst offender in this regard IME. It's the only app I've ever known people have to constantly clear down shared memory / semaphores for when it doesn't shut down cleanly. -- Tony Evans Saving trees and wasting electrons since 1993 blog...

Moving to UNIX
Hi all! Sorry for the newbie type question, but here goes. I have an older laptop, 266 MHZ processor, 80 MB ram with a 2G hard drive.

How do I make "Defined" disks "Available" disks in AIX 5.3 ?
I've been swapping disk around in my RS/6000 and now have: # lsdev -c disk hdisk0 Available 30-58-00-3,0 16 Bit SCSI Disk Drive hdisk1 Available 30-58-00-8,0 16 Bit SCSI Disk Drive hdisk2 Available 30-58-00-9,0 Other SCSI Disk Drive hdisk3 Available 30-58-00-10,0 16 Bit SCSI Disk Drive hdisk4 Defined 30-58-00-13,0 Other SCSI Disk Drive hdisk5 Defined 30-58-00-13,0 16 Bit SCSI Disk Drive How do I turn those "Defined" disks into "Available" disks, so that I can do something with?

I am getting ready to move and have probably a couple hundred 3.5" disks from my Apple IIgs days way back when. I also have some 5.25" disks as well, although not nearly as many. I cannot verify if the contents of what is on the disks is any good anymore, but I was a "warez pup" back in the days and the 3.5" disks were archives of stuff I had downloaded. I would like to donate these as blanks to whoever wants them. I cannot come to grips with simply throwing them away. All I ask is that I be paid shipping costs in return. If you are interested, please contact me by e-mail. Please give my childhood memories a good home and spare them from the trash heap. I'd also like to mention that local pickup is available for no cost what so ever - I am in Pittsburgh, PA -- 15213 zip code, not far from CMU.
