External Disk and multi-boot machine

[pancer]

Im trying to configure external hard drive (scsi) for usage on multi boot machine (4.3,5.1,5.2).Configuring disk for usage on one platform is not a problem but to have this disk R/W ready on all avaliable O.S-es whenever they are booted.....

Now If I boot to other O.S. obviously disk is not configured for use so If I repeat the procedure of configuring the drive and everything else (VG->LV->FS) here I destroy all configured in other O.S.

So what would be the solution for hard drive usage on all O.S. at some time (exportlvg, importlvg__???? have anything to do with this)

Thanks for all replies.

You *can* set up a machine for multi-boot - where you have different AIX levels in different rootvg disks, but you'll have a hard time getting a system with rootvg on one set of disks to start importing another rootvg, because at that point the system will start renaming duplicate LV names (there can only be one /dev/hd4 and one root-filesystem) and will thereby render the other rootvg disks into a rather useless pile of disks.

So if you want to play around with AIX levels like this, you can, but be sure to stay away from the other level's disks once you've booted in one level!

Also, with sharing non-rootvg volume groups on the different AIX levels, there may be issues if you go for attributes or LV types which only work in recent AIX levels...
