error with dump in rc.log

Marilyn DuChene — Mon, 29 Oct 2007 11:26:43 GMT

I'm getting the following error in rc.log:

Configure system crash dumps
Output from "/sbin/rc1.d/S080crashconf start":
----------------------------
/dev/vg00/Dump: warning: duplicate device
EXIT CODE: 0

I'm running hp-ux 11.31

What's configured incorrectly?

#crashconf -v
Crash dump configuration has been changed since boot.

The last line of lvlnboot -v looks strange:

Dump: Dump on: /dev/disk/disk5_p2, 0

should be like

Dump: lvol2 on: /dev/disk/disk5_p2, 0

Note this
Dump: lvol2

Your output shows nothing

Try to set the dump entry again (lvlnboot -d ...) and check again.

Try to remove the entry using http://docs.hp.com/en/B2355-60130/lvrmboot.1M.html and re-create.

I separated my dump and swap. Swap is on lvol2 and dump is on /dev/vg00/Dump.

Set
lvlnboot -d /dev/vg00/dump

(or whatever the LVOL name is) and check again.

I ran the lvlnboot -d /dev/vg00/Dump and the output remains the same. I guess what is confusing me is the mix of the old and new commands, so I'm not sure all is OK, or if I've duplicated something somewhere. Maybe my lvlnboot & crashconf outputs are OK.

I put an entry in my /etc/fstab for my dump, and I disabled my savecrash (SAVECRASH=0). On the /etc/rc.config.d/crashconf I have the following:
CRASHCONF_ENABLED=1
CRASHCONF_READ_FSTAB=1
CRASHCONF_REPLACE=0
CRASHCONF_CONCURRENT_DUMP=1

Do you think I need to have CRASHCONF_READ_FSTAB=0 instead? I see on my crashconf output that my dump is persistent. I don't know if that means it is already set somewhere and I'm trying to set it again?

Your output of lvlnboot is ok, but did you check the fstab for correctness and duplicates?

Here's the entry I put in fstab - is it OK?

/dev/vg00/Dump / dump defaults 0 0

OK - I took out the entry in fstab, and changed the /etc/rc.config.d/crashconf to
CRASHCONF_READ_FSTAB=0. It seems the crashconf -s makes the dump persistent and these are not necessary. I rebooted, and everything shows up OK - so I'm assuming it's OK.
