Hitachi Dynamic Link Manager Software Users Guide for AIX

The following example shows how to place offline all paths connected
to the HBA port whose HBA-port-ID is 00001.
# /usr/DynamicLinkManager/bin/dlnkmgr offline -hbaid 00001
KAPL01102-I All the paths which pass the specified HBA 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
#
-cha -pathid AutoPATH_ID
Use this parameter to place offline, at one time, all the paths that pass
through a specific CHA port. The command will place offline all the paths
that pass through the CHA port to which the path with the specified
AutoPATH_ID is connected. Paths that pass through a physical CHA port
on a physical storage system will be 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 6-34. 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.
Example
The following example shows how to place offline all the paths
connected to the CHA port 0A. In this example, a path whose
AutoPATH_ID is 000001 is connected to the target CHA port.
When the confirmation message is displayed, the user enters y to
continue, or n to cancel the operation.
# /usr/DynamicLinkManager/bin/dlnkmgr offline -cha -pathid
000001
KAPL01055-I All the paths which pass the specified CHA 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 CHA port are
placed in the Offline(C) status, enter y. Otherwise, enter
n. [y/n]:y
KAPL01061-I 2 path(s) were successfully placed Offline(C); 0
path(s) were not. Operation name = offline
