Use this parameter to place offline, at one time, all the paths that pass
through a specific HBA port. The command will place offline all the paths
connected to the HBA port that has the specified host port number and
bus number.
Specify the host port number and bus number of the target HBA port: the
numbers are found in the PathName field displayed using the view
operation. Enter a period between these two parameter values. For
details about the view operation, see
view (Displays Information) on page
6-31.
Example
The following example shows how to place offline all paths connected
to the HBA port whose host port number is 0010 and bus number is
0000:
When the confirmation message is displayed, the user enters y to
continue, or n to cancel the operation.
# /opt/DynamicLinkManager/bin/dlnkmgr offline -hba 0010.0000
KAPL01055-I All the paths which pass the specified HBA 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]:
KAPL01061-I 3 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 6-31. 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 dlmcfgmgr utility
for managing the HDLM configuration. 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:
