of paths to the
device
3
There was an error

failed device
17
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 the
pseudo-LUN and that the device
is now operating with at least one
less path.
N/A
18
A Single Path Fail-Over
