Appendix: Conversion Error MessagesThis appendix lists the error messages that you may encounter when conversting LVM volume groups to VxVM disk groups and volumes. For each error message, a description is provided of the problem, and the action that you can take to troubleshoot it. Error messages that you may encounter during conversion include the following:
For successful conversion, all physical volumes in a volume group must be on-line, and all logical volumes must be active and accessible. Make sure the physical volumes in a volume group are on-line and the logical volumes are active and not in use.
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. 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.
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. You have the following choices:
# vgcfgbackup /dev/vg01 # ln /dev/rdsk/c0t0d0 /dev/rdsk/temp # pvcreate -f /dev/rdsk/temp # rm /dev/rdsk/temp # vgcfgrestore -n /dev/vg01 /dev/rdsk/c0t0d0
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.
If an administrator attempts to convert a Mirrored LVM Volume Group without a valid VxVM license installed, the conversion is not allowed. Install the required license before attempting the conversion.
If there is insufficient private space, the conversion is not allowed to continue. Also, the conversion records already generated are removed such that in the event of an unexpected crash and reboot, the conversion cannot proceed automatically. 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.
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 is aborted. The system responds with an option to complete the conversion by rebooting the system.
The system detects that the vxdiskadd or vxvmconvert program is already running. Retry at a later time. Otherwise, if you are certain that no other users are running either of these programs, remove the file .DISKADD.LOCK from the /var/spool/locks directory to allow you to run vxvmconvert. |
