• Action: The volume containing the DRL log continues in operation. If the system fails
before the DRL has been repaired, a full recovery of the volume’s contents may be
necessary and will be performed automatically when the system is restarted. To
recover from this error, use the vxassist addlog command add a new DRL log to
the volume.
vxvm:vxio:WARNING: Failed to log the detach of the DRL volume volume
• Description: An attempt failed to write a kernel log entry indicating the loss of a
DRL volume. The attempted write to the log failed either because the kernel log is
full, or because of a write error to the drive. The volume becomes detached.
• Action: Messages about log failures are usually fatal, unless the problem is
transient. However, the kernel log is sufficiently redundant that such errors are
unlikely to occur.
If the problem is not transient (that is, the drive cannot be fixed and brought back
online without data loss), recreate the disk group from scratch and restore all of its
volumes from backups. Even if the problem is transient, reboot the system after
correcting the problem.
If error messages are seen from the disk driver, it is likely that the last copy of the
log failed due to a disk error. Replace the failed drive in the disk group. The log
re-initializes on the new drive. Finally force the failed volume into an active state
and recover the data.
vxvm:vxio:WARNING: Failure in RAID-5 logging operation
vxvm:vxio:WARNING: log object
object_name detached from RAID-5 volume
• Description: Together, these errors indicate that a RAID-5 log has failed.
• Action: To restore RAID-5 logging to a RAID-5 volume, create a new log plex and
attach it to the volume.
vxvm:vxio:WARNING: Illegal vminor encountered
• Description: An attempt was made to open a volume device before vxconfigd loaded
the volume configuration.
• Action: None; under normal startup conditions, this message should not occur. If
necessary, start VxVM and re-attempt the operation.
vxvm:vxio:WARNING: Kernel log full: volume detached
• Description: A plex detach failed because the kernel log was full. As a result, the
mirrored volume will become detached.
• Action: It is unlikely that this condition ever occurs. The only corrective action is to
reboot the system.
vxvm:vxio:WARNING: Kernel log update failed: volume detached
• Description: Detaching a plex failed because the kernel log could not be flushed to
disk. As a result, the mirrored volume became detached. This may be caused by all
the disks containing a kernel log going bad.
• Action: Repair or replace the failed disks so that kernel logging can once again
function.
vxvm:vxio:WARNING: mod_install returned errno
