checkpath Command

Syntax

checkpathExG-VPG[ExG-VPG...]

Description

Resume using external volumes. This command executes the same operation as the Check Paths & Restore Volume command which you perform by using the Volume Operation window. After the checkpath command is performed, the local storage system can access the external volumes. For detailed notes on the checkpath command, see (page 93).

The sample file checkPath.txt is provided for your use.

Parameters

Parameter	Description
ExG-VPG	ExG specifies the external volume group in the range of
	E1 to E16384. VPG specifies the serial number within an
	external volume group in the range of 1 to 4096.

Example

The following example resumes using the E1-1 and E1-2 external volumes:

checkpath E1-1 E1-2

checkstatus Command

Syntax

checkstatusExG-VPG[ExG-VPG...]

Description

Retrieves external volume statuses and returns the termination code. The sample file checkStatus.txt is provided for your use.

The external volume statuses are:

•Normal: The external volume is in the normal status.

•Destage: The writing of data from cache memory to the volume is in progress.

•Disconnect: The connection to the external volume is stopped.

•Checking: The checking of the status of the path to the external volume is in progress.

•Blockade: The external volume is blocked.

Parameters

Parameter	Description
ExG-VPG	ExG specifies the external volume group in the range of
	E1 to E16384. VPG specifies the serial number within an
	external volume group in the range of 1 to 4096.

Example

The following example retrieves the statuses of the E1-1 and E1-2 external volumes:

checkstatus E1-1 E1-2
