• Action
No action is necessary; the system will continue.
Failed to log the detach of the DRL volume
vxvm:vxio:WARNING:
Failed to log the detach of the DRL volume volume
• Description
An attempt to write a kernel log entry indicating the loss of a DRL
volume failed. 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 will become detached.
• Action
Messages about log failures are often 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 (i.e. the drive cannot be fixed and
brought back online without data loss), the disk group must be
recreated from scratch and all of its volumes must be restored from
backup.Even if the problem is transient, the system must berebooted
after correcting the problem.
If error messages were seen from the disk driver, it is likely that the
last copy of the log failed due to a disk error. The failed drive in the
disk group should be replaced and the log will then be re-initialized
on the new drive. The failed volume can then be forced into an active
state and the data recovered.
DRL volume is detached
vxvm:vxio:WARNING: DRL volume volume is detached
• Description
A Dirty Region Logging volume became detached because a DRL log
entry could not be written. This might be because of a media failure,
in which case other errors may have been logged to the console.
• Action
The volume containing the DRL log will continue. If the system fails
before the DRL can be repaired, a full recovery of the volume’s
contents may be necessary and will be performed automatically when
