(2) Changing the Status of Paths to Offline(C)
To change the status of paths to
Offline(C):
1. Check the current status of the paths.
To change the status of a path to
Offline(C) by specifying an HBA port, CHA
port, or single path check the path name or PATH_ID used to manage the path.
The following shows an example of executing the command:
# /opt/DynamicLinkManager/bin/dlnkmgr view -path
To place a path Offline(C) by specifying a SCSI device name, check the SCSI
device name of the path.
The following shows an example of executing the command:
# /opt/DynamicLinkManager/bin/dlnkmgr view -lu
2. To change the status of paths to Offline(C), execute the dlnkmgr command's
offline operation.
The paths to be placed offline can be specified by using an HBA port, CHA port,
or single path. Instead of specifying a path, you can also specify a SCSI device
name. For details on how to specify paths, see 6.4 offline (Places Paths Offline).
For example, if you want to place all the paths that pass through a specific HBA
port offline, execute the
dlnkmgr command's offline operation with the -hba
parameter specified. The following shows an example of executing the command:
# /opt/DynamicLinkManager/bin/dlnkmgr offline -hba 0001.0000
KAPL01055-I All the paths which pass the specified HBA 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 HBA are placed
in the Offline(C) status, enter y. Otherwise, enter n. [y/
n]:y
KAPL01061-I 3 path(s) were successfully placed Offline(C); 0
path(s) were not. Operation name = offline
#
3. Check to see if the statuses of all the applicable paths have changed.
The following shows an example of executing the command:
# /opt/DynamicLinkManager/bin/dlnkmgr view -path
