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 host
device.
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).

6.4.2 Parameters
(1) To Place Paths Offline
-path
Indicates that the target of the operation is a path managed by HDLM.

assumed.
Make sure that you specify the paths to be placed offline by using the
-hba
,
-hbaid
,
-cha
,
-chaid
, or
-pathid
parameter, or the
-hdev
and
-ospathid
parameters.
