76 Conversion error messages
Device device_name has the
following bad blocks... Cannot
convert LVM Volume Group
Unlike LVM, VxVM does not support bad
block revectoring at the physical volume
level. If there appear to be any valid bad
blocks in the bad block directory (BBDIR) of
any disk used in an LVM volume group, the
group cannot be converted.
To clear the BBDIR:
1 Stop all access to the physical volume,
and back up all the data in thevolume
group.
2 If the errors are persistent or the disk
has not been replaced, have a certified
engineer revector the blocks or replace
the disk.
3 Back up the LVM headers, for example:
# vgcfgbackup /dev/vg01
4 Close all the logical volumes
associated with the volume group, and
then deactivate the volume group.
5 Create a dummy link to the raw device,
for example:
# ln /dev/rdsk/c0t0d0 \
/dev/rdsk/temp
6 Destroy the LVM headers on the
dummy link:
# pvcreate -f /dev/rdsk/temp
7 Remove the dummy link to the raw
device:
# rm /dev/rdsk/temp
8 Restore the headers from the
lvmconf backup, for example:
# vgcfgrestore -n /dev/vg01 \
/dev/rdsk/c0t0d0
9 Activate the volume group. Check the
integrity of the data, or recover the
data from a backup.
