(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
