HP XP7 Storage - Manual (Page 169)

The paths to be placed offline can be specified by using an HBA port, CHA
port, single path, or HBA port WWN. For details on how to specify paths,
see offline (Places Paths Offline) on page 6-6 .
For example, if you want to place all the paths that pass through a
specific HBA port offline, execute the dlnkmgr command's offline
operation with the -hba parameter specified. The following shows an
example of executing this command:
PROMPT>dlnkmgr offline -hba 1.1
KAPL01055-I All the paths which pass the specified HBA port will
be changed to the Offline(C) status. Is this OK? [y/n]:y
KAPL01056-I If you are sure that there would be no problem when
all the paths which pass the specified HBA are placed in the
Offline(C) status, enter y. Otherwise, enter n. [y/n]:y
KAPL01061-I 3 path(s) were successfully placed Offline(C); 0
path(s) were not. Operation name = offline
PROMPT>
3
.
Check to see if the statuses of all the applicable paths have changed.
The following example shows how to execute the command:
dlnkmgr view -path

To display LU information, execute the dlnkmgr command's view operation
