Conversion Error Messages

Device device_name has the following bad blocks... Cannot convert LVM Volume Group

Device device_name has the following bad blocks... Cannot convert

LVM Volume Group

• Description

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 of any disk used in an LVM volume group, the group

cannot be converted.

• Action

You have the following choices:

— Place a hardware call to have the disk replaced or have the hardware engineer use the diagnostics (if

applicable for this disk type) to re-vector the block. Then clear the BBDIR as described below.

— If the errors were transient, or after the disk has been replaced, clear the BBDIR as follows:

a. Back up all the data associated with the physical volume.

b. Make a current backup of the LVM headers, for example:

# vgcfgbackup /dev/vg01

c. Close all the logical volumes associated with the volume group and then deactivate the volume

group.

d. Create a dummy link to the raw device, for example:

# ln /dev/rdsk/c0t0d0 /dev/rdsk/temp

e. Destroy the LVM headers using pvcreate -f on the dummy link, for example:

# pvcreate -f /dev/rdsk/temp

f. Remove the dummy link to the raw device, for example:

# rm /dev/rdsk/temp

g. Restore the headers from the lvmconf backup, for example:

# vgcfgrestore -n /dev/vg01 /dev/rdsk/c0t0d0

h. Activate the volume group and integrity check the data or recover from backup.

The conversion process was unable to deactivate the volume group

vol_grp_name

• Description

This indicates that the conversion process cannot deactivate the volume group.

• Action

The conversion cannot be completed without rebooting the machine. If you cannot afford to reboot, then

choose abort and try again later.
