Hitachi Dynamic Link Manager Software Users Guide for AIX (6.6) (T5208-96010, April 2011)

6. Command Reference
239
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 (3) To Display LU Information in
6.7.2 Parameters. 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 hdisk0 -ospathid 1
KAPL01052-I The currently selected paths will be changed
to the Offline(C) status. Is this OK? [y/n]:y
KAPL01053-I If you are sure that there would be no problem
when the path is placed in the Offline(C) status, enter
y. Otherwise, enter n. [y/n]:y
KAPL01061-I 1 path(s) were successfully placed
Offline(C); 0 path(s) were not. Operation name = offline
#
-s
Executes the command without displaying the message asking for confirmation
of command execution from the user. Specify this parameter if you want to skip
the response to the confirmation message: for example, when you want to execute
the command in a shell script or batch file.
