absolutely valid and up-to-date. Restoring invalid configuration data can result
in data corruption later.
If there are alternate physical volume links configured in the system, the follow-
ing message will appear when total number of physical volumes in the kernel
does not match with the configuration backup file due to missing alternate physi-
cal volume links:
Mismatch between the backup file and the running kernel: Kernel indi-
cates X disks for /dev/vgname; /etc/lvmconf/vgname indicates Y disks.
Cannot proceed with the restoration. Deactivate the Volume Group and
try again.
In this case, the user is advised to deactivate the volume group first, then use
the vgcfgrestore command to restore configuration data when the volume
group is unavailable. But if the volume group has to stay available and the user
is absolutely sure the configuration file is correct, this option will restore data
from the configuration file when the volume group stays available.
-v Provide additional information when invoked together with -l option.
• Additional values displayed for each path:
• Disk size in kilobytes
• Starting block number (kb) of the user data.
• The PVkey (see lvdisplay -k). Note that paths with the same key are
links to the same device.
Additional values displayed for each volume group:
• max_pv
• max_pe
• max_lv
RETURN VALUE

EXAMPLES
Restore the LVM configuration information for the physical volume
/dev/rdsk/c0t7d0 that was saved
in the default file
/etc/lvmconf/vg00.conf:
vgcfgrestore -n /dev/vg00 /dev/rdsk/c0t7d0
Force to restore the LVM configuration data when volume group is still active
vgcfgrestore -R -n /dev/vg00 /dev/rdsk/c0t7d0
Restore the LVM configuration information to physical volume /dev/rdsk/c0t4d0 using alternate
configuration file
/tmp/vg00.backup:
vgcfgrestore -f /tmp/vg00.backup /dev/rdsk/c0t4d0
List backup information saved in default configuration file /etc/lvmconf/vg00.conf:
vgcfgrestore -n /dev/vg00 -l
