HP XP Racks - Manual (Page 215)

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 6-32 . 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 6-52 in Parameters on page 6-34 . Only one set of values can
be specified for the -hdev parameter. This parameter is not case
sensitive.
Example
The following shows an example of placing offline path for which the
host device name is hdisk0 and OS management path ID is 00001
while confirming command operation.
# /usr/DynamicLinkManager/bin/dlnkmgr offline -path -hdev
