You can query, update, and delete client-owned disks that reside in a Storage Area Network. These disks are defined to Tivoli Storage Manager in order to take advantage of server-free data movement.
By using the QUERY DISK command, you can obtain information about client-owned disks that reside in a SAN environment. You can request either a standard or a detailed report. For example, to display a standard report about all defined disks, issue the following command:
query disk *
The following shows an example of the output from this command.
+--------------------------------------------------------------------------------+ |Node Disk Online | |Name Name | |------------ ------ ------ | |NODE1 Harddisk1 Yes | |NODE2 Harddisk2 Yes | +--------------------------------------------------------------------------------+
You can update an existing disk by issuing the UPDATE DISK command. The example below shows how you can use the UPDATE DISK command to change the world wide name, serial number, and status of a disk.
Update a disk named Harddisk1 owned by NODE1. The world wide name to 20020060450d00e2 and the serial number to 100047. Change the ONLINE status to YES.
update disk node1 Harddisk1 wwn=20020060450d00e2 serial=100047 online=yes
All paths related to a disk must be deleted before the disk itself can be deleted.
Delete a disk named Harddisk1 that is owned by the node NODE1.
delete disk node1 Harddisk1
