Appendix A Conversion Error Messages

This appendix lists the error messages that may be encountered during conversion of LVM volume groups to VxVM disk groups and volumes. It describes what the problem is and how to troubleshoot it.

Some of the error messages you may encounter during conversion are:

Message - vxdiskadm or vxvmconvert is already being run.
Message - Too many LVM Volumes to convert in this LVM Volume Group.
Message - vgchange: Couldn't deactivate volume group /dev/vol_grp.
Message - Analysis shows that there is insufficient private space available to convert this volume group.
Message - Analysis indicates that this volume group cannot be converted because not all of the disks and/or volumes in the LVM volume group are currently accessible.
Message - The conversion process was unable to deactivate the volume group vol_grp_name. The conversion cannot proceed without reboots being done. If you choose to not reboot your system, the conversion will be aborted.
Message - This Volume Group contains one or more logical volumes with mirrored data. Conversion of this Volume Group requires that the VxVM package on your system be enabled for mirroring. This system does not appear to have VxVM mirroring enabled. Please check your installation and licensing of VxVM before attempting a conversion of this Volume Group.
Message - Device device_name has the following bad blocks:... Cannot convert LVM Volume Group, vgXX.

Message

vxdiskadm or vxvmconvert is already being run.
 
The vxdiskadm or vxvmconvert program is already being
run and these programs cannot run concurrently.
Please retry this at a later time.
 
If you are certain that no other users are running any of
these programs, you can remove the file:
/var/spool/locks/.DISKADD.LOCK

Description
The system detects that the vxdiskadd or vxvmconvert program is already running.
Action
You can retry at a later time. If you are certain that no other users are running any of these programs, you can remove the file DISKADD.LOCK.This allows you to run vxvmconvert. The lock file is present in:
/var/spool/locks/.DISKADD.LOCK

Message

Too many LVM Volumes to convert in this LVM Volume Group
 
Too many LVM Volumes to convert in this Volume Group.
The conversion utility will calculate how much private
area VxVM will need to convert the LVM volume group.

Description
If private space is not large enough, then the conversion will not be allowed to continue. Also, the conversion records already generated will be removed such that in the event of an unexpected crash and reboot, the conversion will not proceed automatically.
Action
You can reduce the number of logical volumes in volume group by combining some of the logical volumes together, or by aborting. You can restart the conversion process later with fewer volumes in the group.

Message

vgchange: Couldn't deactivate volume group /dev/vol_grp
 
vgchange: Couldn't deactivate volume group /dev/vol_grp_name.  Device busy.
 
Finish Conversion via reboots? [y,n,q,?] (default: y) n

Description
The conversion process was unable to deactivate the volume group. The conversion cannot proceed without reboots being done. If you choose to not reboot your system, the conversion will be aborted.
Action
The system responds with an option to complete the conversion by rebooting the system.

Message

Analysis shows that there is insufficient private
space available to convert this volume group.

Description
The error message indicates the maximum amount of records that can be stored in the private space, and how many records are needed to convert this particular volume group.
Action
You can reduce the number of records needed by reducing the number of logical volumes in volume group by combining some of the logical volumes together.

Message

Analysis indicates that this volume group cannot be
converted because not all of the disks and/or volumes
in the LVM volume group are currently accessible

Description
For successful conversion, all physical volumes in a volume group must be on-line, and all logical volumes must be active and accessible.
Action
Make sure the physical volumes in a volume group are on-line and the logical volumes are active and not in use.

Message

The conversion process was unable to deactivate the
volume group vol_grp_name.  The conversion cannot
proceed without reboots being done. If you choose
to not reboot your system, the conversion will be
aborted.

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.

Message

This Volume Group contains one or more logical volumes
with mirrored data.  Conversion of this Volume Group
requires that the VxVM package on your system be enabled
for mirroring.  This system does not appear to have VxVM
mirroring enabled.  Please check your installation and
licensing of VxVM before attempting a conversion of this
Volume Group.

Description
If an administrator attempts to convert a Mirrored LVM Volume Group without a valid VxVM Mirror license installed, the conversion is not allowed.
Action
Install the Mirror license before attempting the conversion.

Message

Device device_name has the following bad blocks:
 
[1] bad block number (PE# n data block bnum) alternate number
Cannot convert LVM Volume Group, vgXX

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:
  Back up all the data associated with the physical volume.
  Make a current backup of 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 using pvcreate -f on the dummy link, for example:
  pvcreate -f /dev/rdsk/temp
  Remove the dummy link to the raw device, for example:
  rm /dev/rdsk/temp
  Restore the headers from the lvmconf backup, for example:
  vgcfgrestore -n /dev/vg01 /dev/rdsk/c0t0d0
  Activate the volume group and integrity check the data or recover from backup.
