HELP! Root Disk Failing!

[Lisa Egbert]

I have an old HP9000 running 11i. It has only two internal drives. The one with the root partition has gone bad. With Sun I could replace the drive and boot from the cdrom and reinstall the os, however I seem to be unable to do this. I would appreciate advice.

Replace the disk.

Take your trusty make_tape_recovery backup tape. Put it in the tape drive.

boot your box.

at the console, interupt at the 10 second prompt.

sea

Find the sequential device.

Bo P3

If the device next to P3 is sequential(tape)

Don't have a tape made:

Do like you'd do with sun.

Put the core os cd in the cd drive and boot off that.

Same basic procedure as above, just pick the device that is the CD-rom, you may need to try a few times to get it right because the CD-ROM is just like disk, random access.

Hi Lisa,

Is it down now? If the problem is intermittent, then I suggest you create a make_tape_recovery tape, replace the disk and recover it.

If it is down and if you don't have make_tape_recovery tape, then the best you can do is to replace the disk and install the OS. If the other disk was also part of vg00 and if there are logical volumes shared between those two disks, then you will lose the data on those logical volumes. Once the install is done, try importing the other disk in the following way.

#mkdir /dev/vg01
#mknod /dev/vg01/group c 64 0x010000
#vgimport vg01 /dev/dsk/cxtydz
This may give errors like there should have been two disks. Activate the VG
#vgchange -a y vg01
If the above doesn't work then do
#vgchange -a y -q n vg01
You will find the LV devices under /dev/vg01 directory. Mount them and see if you have data. If so, take a backup of the data, add the disk back to vg00 or create a new VG, create lvols and filesystems and restore the data.

I have tried to boot from cd, with no success. It is an external cd drive (not sure if that matters) and when I try 'sea ipl' it doesn't find that device. Any suggestions?

No matter external cd drive.Check for the SCSI Termination and connectivity.Check for CD drive is functional or not.There shouldn't be any compactability issues.There could be some possible hardware failures,since your root disk is also crashed.Do a proper analysis

The drive is operational - I am able to mount the cd.

PS - I don't have a tape drive on this machine either

[Lisa Egbert]

Sorry - mean to say, evidently don't have make_tape_recovery on this machine. (And of course I inherited this debacle!) Is make_tape_recovery part of Ignite?

[Edgar_8]

Hi Lisa,

Yes, make_tape_recovery is part of HP Ignite-UX.
