6.4 offline (Places Paths Offline)
The
dlnkmgr
command's
offline
operation places online paths offline. Specify the
paths to be placed offline by specifying an HBA port, CHA port, single path, or HBA
port WWN.
There must always be at least one online path accessing each LU.
Placing too many paths offline might prevent paths from being able to switch if an
error occurs. Before placing a path offline, use the
view
operation to check how many
online paths remain. For details about the
view
operation, see 6.7 view (Displays
Information).
In a cluster configuration, an
offline
operation requested during reserve processing
is put into the waiting-to-execute state (
Online(P)
,
Online(EP)
, or
Offline(P)
),
and does not execute until the reserve processing finishes.
