4.3.3 Changing the status of paths

This subsection explains how to change the status of paths.

Organization of this subsection

(1) When changing the status of a path to online

(2) When changing the status of a path to Offline(C)

(1) When changing the status of a path to online

To change the status of a path to online:
Check the current status of the path.
To change the status of the path for each HBA port, channel adapter port, or path to online, check the path name or AutoPATH_ID.
The following example shows how to execute the command:
 
>dlnkmgr view -path
 
To change the status of a path to online, execute the dlnkmgr command's online operation.
You can specify the paths you want to place online by specifying an HBA port or channel adapter port to which the target paths are connected, or by specifying a single path. However, you can specify the online operation for a channel adaptor port only when the HDLM management-target device is the Thunder 9200/9500V series, Lightning 9900/9900V series, TagmaStore, and Universal Storage Platform V. For details on how to specify a path, see 7.5 online (Places a path or paths online).
For example, if you want to place all 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 in which the command is executed:
 
>dlnkmgr online -hba 1.1
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) could not be placed online. Operation name = online
> 
 
Check the changed status of the path.
The following example shows how to execute the command:
 
>dlnkmgr view -path
 

(2) When changing the status of a path to Offline(C)

To change the status of a path to Offline(C):
Check the current status of the path.
To change the status of the path for each HBA port, channel adapter port, or path to Offline(C), check the path name or AutoPATH_ID.
The following example shows how to execute the command:
 
>dlnkmgr view -path
 
To change the status of the path to Offline(C), execute the dlnkmgr command's offline operation.
You can specify the paths you want to place online by specifying an HBA port or channel adapter port to which the target paths are connected, or by specifying a single path. However, you can specify the offline operation for a channel adaptor port only when the HDLM management-target device is the Thunder 9200/9500V series, Lightning 9900/9900V series, TagmaStore, and Universal Storage Platform V. For details on how to specify a path, see 7.4 offline (Places a path or paths offline).
For example, if you want to place all 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 in which the command is executed:
 
>dlnkmgr offline -hba 1.1
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) could not be placed offline(C). Operation name = offline
> 
 
Check the changed status of the path.
The following example shows how to execute the command:
 
>dlnkmgr view -path
