vxvm database cleanup

Bob Moore_1 — Mon, 22 Mar 2004 10:53:19 GMT

I am running vxvm on superdomes and want to know how to cleanup old entries for disks in the vxvmdb. I have been adding and deleting drives and it seems the only way to get vxvm to cleanup after itself is to reboot. Is there a way to get vxvm to get rid of old disk entries without rebooting?

Have you take a look at the vxdctl command?

# vxdctl rm

Wow...that totaly sounded like a "RTFM"
LOL..which btw, is exactly what i needed. :-)
Yup..there it is in the man page..

#vxdctl rm disk

Thanks for the kick in the pants!!

well....that doesn't seem to work.. :-(
i get an error when i use the name given the disk in vxvm. like EMC0_117..and i can't use the ctd number because it's gone..i've already run rmsf on on the NO_HW devices. I also tried vxdisk rm disk..no luck..

root@hostname:>vxdisk rm disk EMC0_117
vxvm:vxdisk: ERROR: Failed to obtain locks:
disk: no such object in the configuration

root@hostname:>vxdctl rm disk EMC0_117
vxvm:vxdctl: ERROR: Cannot remove disk device EMC0_117: Record not in disk group

Am i doing something wrong?

thanks,
BOB

Been a while since I worked with VxVM. Reviewing the vxdctl man page, I'm thinking "vxdctl enable" might work.

vxdctl enable only seems to rescan for new disks and adds them..it doesn't remove any of the old devices.

ARRRG!! I got it..my syntax was wrong in using the vxdisk rm command...it's supposed to be:

vxdisk rm
not
vxdisk rm disk

thanks for the help..your initial "rtfm" was correct..you're not losing your mind.. LOL..

thanks again for the help,
BOB
