D350 won't complete boot

The DDS3 tape drive stopped working in our D350. I shutdown the system and installed the new drive making sure any jumpers matched the old drive. I booted the system back up and it won't come all the way up.

The machine is running HP-UX 11.0.

When it boots I hear three beeps that I don't remember from before but I don't usually hang around while it boots. It gets to the following point on the console:
Checking for LVM volumegroups and Activating (if any exist)
Volume group "/dev/vg00" has been successfully changed.

I have tried boot several times and it always gets stuck at that point.

I have also removed the tape drive and tried booting without it.

Help. Since the tape drive was dead we don't know if we have a really good backup.

I'd try booting in single user mode; then have a look at /etc/rc.log

Re: D350 won't complete boot

control b (* enter GSP *)
rs (* reset server from GSP *)
interrupt boot cycle (* 10 sec prompt *)
bo pri
interact with ipl
yes
ISL> hpux -is
...note errors
# init 1,2,3

-or-

# sh -x /etc/rc.config

Either will debug your boot up process by daemon and run level startup.

If you can't 'hpux is' then repeat procedure with 'hpux -lm -is'.

'hpux -lm -is' (* LVM maintenance mode *) will bypass the bootlif and use /stand/rootconf instead. If successful then your bootlif is corrupt.

What about alternate boot disks?

sea ipl (* from BCH *)
bo alt

And previous kernel if primary is corrupt.

ISL>hpux /stand/vmunix.prev

Re: D350 won't complete boot

Also check if anyone has messed with the /sbin/lvmrc and /etc/lvmrc files. Those are script and var-setting files related to VG activation upon startup. Of course you can only check it if you're able to at least boot up in single-user mode (vg00 will be activated) or LVM-maintenance mode (vg00 will not be activated).
