Hi,

check in /etc/lvmrc
if the variable
AUTO_VG_ACTIVATE=1

If you want that all vgs are activated automatically when the system was booted ,loook for an entry in /etc/lvmrc

it should be
+++++
# The activation of Volume Groups may be customized by setting the
# AUTO_VG_ACTIVATE flag to 0 and customizing the function
# custom_vg_activation()
#

#
# To disable automatic volume group activation,
# set AUTO_VG_ACTIVATE to 0.
#

AUTO_VG_ACTIVATE=1
+++++

Good luck !

Andreas i right check for the entry in the /etc/lvmrc.

First I would check the disk whether it is claimed using
ioscan -fnC disk

Also try doing a diskinfo on the disk to check whether the disk is okay.


When you tell that manual activation is working then,

I assume that the vg info was lost.

Can you do a
#vgcfgrestore -n /dev/vg01 /dev/rdsk/cXtYd0

check for the man pages of the vgcfgrestore.


Thanks

hello every body,

thanks for the reply .

i have check the /etc/lvmrc and it is ok

AUTO_VG_ACTIVATE=1

i think that the file system is corrupted the vg is not activated at start up the system give a error message
"Warning: Couldn't attach to the volume group physical volume "


so,i activate it manualy with vgcange command and i mount the file system manualy then.

how can i recovere this ? can i do an export and an import after running fsck command ??

give the steps please

hi

are you shure that the fstab have the correct strings for your mount point?

You can check this umounting vg01 and run mountall.

attach the following:

strings /etc/lvmtab

pvdisplay all PVs in VG01

ioscan -fnkC disk

ll /dev/vg01/

cat /etc/fstab

vgchange -a y vg01

vgdisplay -v vg01

Later,
Bill

vg 01 has one disk and when running ioscan it is claimed
