connected to the target CHA port:

#
-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 6.7 view (Displays
Information) . 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.
-device
SCSI-device-name
Use this parameter to place offline a path connected to the specified SCSI device.
For
SCSI-device-name , specify the value of
Device
displayed by executing the
view
operation as follows:
# /opt/DynamicLinkManager/bin/dlnkmgr view -lu
For details on how to execute the
view
operation and display the SCSI device
name, see (3) To display LU information in 6.7.2 Parameters (To display
program information) . Only one case-sensitive parameter value can be specified.
