HP XP P9500 Storage - Manual (Page 358)

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 6-28 .

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
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.
Specify the host port number and bus number of the target HBA port: the
numbers are found in the PathName field displayed using the view
operation. Enter a period between these two parameter values. For
details about the view operation, see view (Displays Information) on page
6-28 .
Example
The following example shows how to place offline all paths connected
to the HBA port whose host port number is 0010 and bus number is
0000:
