Re: /dev/vg00 deleted - no mapfile
to know about waht disks were a part of vg00
u can also run the vgcfgrestore command in the following manner depending on that the VG vg00 LVM Conf backup file that is as /etc/lvmconf/vg00.conf is okay and that shud be OK.
#vgcfgrestore -l -n vg00
or
#vgcfgrestore -l -f /etc/lvmconf/vg00.conf /dev/vg00

Re: /dev/vg00 deleted - no mapfile
remeber that even if u have not a map file for a VG, u can still import the VG and get that running if u know the list of the PVs in that VG.
and if u have forgot that list of PVs also u can get that if u have an intact VG conf file for that VG, generally kept as /etc/lvmconf/
and u can get this by
#vgcfgrestore -l -n /dev/
or
by
#vgcfgrestore -l -f /etc/lvmconf/
-l option of vgcfgrestore is for listing the PVs and some other informations ... do not worry.
this list u the PVs which u can use witht the vgimport command.
Please refer to the man pages of vgcfgrstore(1M) and vgimport(1M) for the further details.

Re: /dev/vg00 deleted - no mapfile
read the post of Torsten that u can vgimport root vg even if u have no map file.
but the vgexport and vgimport that is rewd to solve this scenario can be done only in LVM Maintenance mode.
Please reboot in LVM maintenance mode.
and post the errors that u get in the LVM Maintenance mode.
The error that u are getting is due to the fact that u have those lvol files created.
the /stand/ioconfig file is intact but the /etc/ioconfig is not valid.
u will need to recreate but do not worry fpr that
first boot the system in LVM Maintenance mode and tell me what u can see the system says.
Regards
Sujit

Re: /dev/vg00 deleted - no mapfile
If not, tell us your server model (HP9000 or Integrity) and we can guide you ...
Hope this helps!

Torsten.

Re: /dev/vg00 deleted - no mapfile
If you don't mind, tell everybody what you did exactly to fix it. It is not clear that it was the LVM maintenance mode or a simple reboot to sync the ioconfig files.
Without a confirmed solution, this entire thread with all these great answers is totally useless.
