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 view (Displays Information) on page 6-29 .
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.

Parameters
To Place Paths Offline
-path
Indicates that the target of the operation is a path managed by HDLM.
This parameter is optional because offline is always used for paths, so it
is assumed.
Make sure that you specify the paths to be taken offline by using the -
hba, -cha, -pathid, or -hbaportwwn parameter.
-hba host-port-number.bus-number
Use this parameter to place offline, at one time, all the paths that pass
through a specific HBA port. The command will place offline all the paths
connected to the HBA port that has the specified host port number and
bus number.
