4.2.3 Changing the Status of Paths

This section explains how to change path statuses.

(1) Changing the Status of Paths to Online

To change the status of paths to online:
1.

Check the current status of the paths.
To place paths online 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 paths online 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 online, execute the

dlnkmgr

command's

online

operation.
The paths to be placed online 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 6.5 online (Places Paths Online).
For example, if you want to place all the paths that pass through a specific HBA

port online, execute the

dlnkmgr

command's

online

operation with the

-hba

parameter specified. The following shows an example of executing the command:


# /opt/DynamicLinkManager/bin/dlnkmgr online -hba 0001.0000
KAPL01057-I All the paths which pass the specified HBA will
be changed to the Online status. Is this OK? [y/n]:y
KAPL01061-I 3 path(s) were successfully placed Online; 0
path(s) were not. Operation name = online
#

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
