Shredding volumes in parity groups

Prerequisites

You must have the Storage Administrator (Provisioning) role to perform this task.

Procedure

Display the parity group to be shredded:

In Hitachi Command Suite:

On the Resources tab, click Storage Systems, and then expand All Storage Systems and the target storage system.

Right-click Parity Groups, and then select System GUI.

In Device Manager - Storage Navigator: Display the Parity Groups tab by choosing one of the following steps, depending on the location of the parity group:

In the Storage Systems tree, select Parity Groups.

In the Storage Systems tree, select Parity Groups, and then select Internal or External.

Select the parity group you want to shred and confirm the current status by viewing the Status column of the table.

If the parity group is already blocked, Blocked appears in the status column.

If the parity group is not blocked, a status other than Blocked appears in the status column. In this case, you need to block the parity group before you can shred it. See Blocking volumes in a parity group.

Click More Actions > Shred LDEVs.

To save the shredding results to a file, click Set Data Output (you can output the shredding results of up to three volumes). If you don’t want to save the results to a file, click Cancel Data Output.

Click Finish.

Verify the settings in the Shred LDEVs window.

When the settings are correct, enter a unique task name or accept the default name, and click Apply.

If Go to tasks window for status is selected, the Tasks window will open.
