A fail-over on pseudo-LUN
occurred.
A pseudo-LUN handled a failover. This
message does not indicate whether the
failover was successful.
The Path ID of the failed
device

Pseudo-LUN is currently in a
degraded state. One or more
paths have failed, though the
process is now complete.
At least one path to a pseudo-LUN has failed.
This signals the end of failover handling for
thepseudo-LUNandthatthedeviceisnow
operating with at least one less p ath.
N/A

A Single Path Fail-Over is being
attempted on pseudo-LUN
A pseudo-LUN has just one path, and DSM
has requested a failover.

An operation failed on device due
to lack of memory.
Resource allocation failed during an
attempted failover, and failover is not currently
active.

A Path Verification request
to a device on pseudo-LUN that
is controlled by DSM_name has
failed. This may indicate a path
failure.
AcalltoaDSM’sPathVerifyroutinetoa
pseudo-LUN has failed. This event occurs
during final initialization after PathVerify has
checked whether the device can be reached
through a newly found path.
N/A

The internal state of device_ob-
ject is inconsistent. This
indicates potential failures in
this support.
