6. Command Reference

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, or single path. Instead
of specifying a path, you can also specify a SCSI device name.
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 on the
view
operation, see 6.7 view (Displays
Information).

(1) To place paths offline
-path
Indicates that the target of the operation is a path managed by HDLM.

assumed.

-hba
,
-hbaid
,
-cha
,
-chaid
,
-pathid
, or
-device
parameter.
