HP XP P9500 Storage - Manual (Page 221)

Use this parameter to place offline, at one time, all paths that pass
through a specific CHA port. The command will place offline all paths
connected to the CHA port that has the specified CHA-port-ID. To display
the CHA port IDs, execute the following view operation:
# /usr/DynamicLinkManager/bin/dlnkmgr view -cha
For details about how to execute the view operation to display the CHA
port IDs, see To Display CHA Port Information on page 6-66 in
Parameters on page 6-35 .
Example
The following example shows how to place offline all paths connected
to the CHA port whose CHA-port-ID is 00001.
# /usr/DynamicLinkManager/bin/dlnkmgr offline -chaid 00001
KAPL01102-I All the paths which pass the specified CHA port
will be changed to the Offline(C) status. Is this OK? [y/n]:y
KAPL01103-I If you are sure that there would be no problem
when all the paths which pass the specified HBA port are
placed in the Offline(C) status, enter y. Otherwise, enter n.
[y/n]:y
KAPL01061-I 15 path(s) were successfully placed Offline(C); 0
path(s) were not. Operation name = offline
#
-pathid AutoPATH_ID
Use this parameter to place a single path offline.
Specify the current AutoPATH_ID of the target path, which is displayed by
using the view operation. For details about the view operation, see view
(Displays Information) on page 6-33 . Leading zeros can be omitted
(000001 and 1 indicate the same AutoPATH_ID); however, when the
target AutoPATH_ID is 000000, enter 000000 or 0 for the parameter
value.
AutoPATH_IDs are re-assigned every time the host is restarted. When you
want to add a new LU without restarting the host, AutoPATH_IDs are re-
assigned to each path of the LU when you execute the cfgmgr command.
Always make sure that you use the view operation to find the current
AutoPATH_ID of the target path, before executing the offline operation.
-hdev host-device-name -ospathid OS-management-path-ID
Use this parameter to place offline path connected to the specified host
device.
For host-device-name, specify the value of HDevName.
For OS-management-path-ID, specify the value of OSPathID. Leading
zeroes can be omitted from the OS management path ID (00001 and 1
are the same value).
To display HDevName and OSPathID, execute the view operation as
follows:
# /usr/DynamicLinkManager/bin/dlnkmgr view -lu
For details on how to execute the view operation and display the host
device name and OS management path ID, see To Display LU Information
on page 6-54 in Parameters on page 6-35 . Only one set of values can
