Make_recovery on a different SCSI chain

[Pamela Hammitt]

I tried to restore my crashed system that was previously on a SCSI 3 chain to new harddrives on a SCSI 2 chain...This didn't work...my cfg files for the volume group and harddrive device files referenced c0t0d6 instead of c1t0d6...I rebooted and used the interactive gui to install to new hardware??? Any suggestions...I was also unable to import the volume groups because of the device file and cfg file mismatches... In the meantime, I manually rebuilt the volume groups on SCSI 2 and made make_tape_recovery and included all volume groups, then restored to a new set of harddrives on SCSI 2...

Bottom line, can you successfully go from SCSI 3 to SCSI 2 without having to rebuild everything?

Hi,

it should be enough to boot the LVM mainteanance mode (hpux -lm), move away /etc/lvmtab and then use the vgscan command to re-create it with the current values.
