I would not recommend splitting the disks. All the time that you are busy the disk you moved will be complaining about a PMISSING volume. Instead, hopefully it is installed, I would use the mkcd command to create CDROM iso images of your rootvg and burn the iso images on a PC and use these to install on a second server, making changes as needed later.

Otherwise, I would break the mirror, and use alt_disk to clone a copy and move the cloned copy for an install on a second system (or add a new disk and clone to that. This is probably the ideal solution).

RS/6000 RootVG hdisk migrate

« on: February 08, 2010, 12:49:02 PM »

I'm having the following issue:

I have 2 old RS/6000 Power3 servers with 1GB of RAM and 4x19GB disks.

1 Server is still in production and within this company there isn't any information on this machine, so i must be carefull with it.

Now they need an exact copy of that machine into the spare RS/6000.
The server is running AIX5.1 ML04 .
There isn't any working NIM server around but the copy has to be made asap.

I've had the idea because rootvg is a mirror on 2 physical disks, to poweroff the production server.
Move 1 of the rootvg disks into the spare one, and boot with a Diagnostics CD to set the bootrecord and stuff, and boot it, change IP adress and mirror it to another internal disk. Put the original rootvg disk back at the production machine again and I should be up & running with both machines within 1 day?

Can someone let me know if it has worked for you in the past?
