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 about the view operation,
see view (Displays Information) on page 6-30 .

{-hba host-port-number.bus-number

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 -device parameter.
-hba host-port-number.bus-number
