Disk inaccessable?

Joakim Brosten — Mon, 18 Aug 2008 18:17:23 GMT

Hi, can any one give me a push in right direction? I have a rx2600 that hangs during boot, it seems like something with the volume group vg00. The boot process then stops here.
Thanks in advance, /Joakim

/sbin/bcheckrc:

Hi Joakim,

Check your disks in group vg00, check boot disks and compare it to the /stand/bootconf file.

If one of the disks was replaced bootpaths should be updated - setboot and /stand/bootconf

Thanks Ivan, should I boot the server in single mode in order to access the prompt and make the commands you're suggesting?

No, the server should boot normally. If not - use single mode or alternate boot path.
Search in BCH prompt for boot sevices.

After booting:

Just check the boot paths:
# lvlnboot -v

Check disks in vg00:
# vgdisplay -v vg00

Check /stand/bootconf

If it is necessary set new boot paths with setboot - http://docs.hp.com/en/B3921-90010/setboot.1M.html

Thanks again Ivan,

But... The server stops here, after checking the file systems on vg01. I guess vg00 contains the inaccessible root file system.

Can I reach and fix vg00 from EFI, or should I reinstall OS?
Other way of fixing vg00?
