Conversion error messages (continued)
DescriptionMessage
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 BBDIRcomplete the following steps
in the order shown:
■ Stop all access to the physical volume, and
back up all the data in thevolume group.
■ If the errors are persistent or the disk has not
been replaced, have a certified engineer
revector the blocks or replace the disk.
■ Back up the LVM headers, for example:
# vgcfgbackup /dev/vg01
■ Close all the logical volumes associated with
the volume group, and then deactivate the
volume group.
■ Create a dummy link to the raw device, for
example:
# ln /dev/rdsk/c0t0d0 \
/dev/rdsk/temp
■ Destroy the LVM headers on the dummy link:
# pvcreate -f /dev/rdsk/temp
■ Remove the dummy link to the raw device:
# rm /dev/rdsk/temp
■ Restore the headers from the lvmconf backup,
for example:
# vgcfgrestore -n /dev/vg01 \
/dev/rdsk/c0t0d0
■ Activate the volume group. Check the integrity
of the data, or recover the data from a backup.
Device device_name has the following bad
blocks... Cannot convert LVM Volume Group
This indicates that the conversion process cannot
deactivate the volume group.
The conversion cannot be completed without
rebooting the machine. If you cannot afford to
reboot, then choose abort and try again later.
