Disconnecting an external storage system, all mapped volumes
When you disconnect an external system, the mapped external volumes in the system are also disconnected. This is the primary method for disconnecting all the mapped volumes in an external system.
Before disconnecting a mapped volume, review Prerequisite requirements.
Prerequisites
You must have Storage Administrator (Provisioning) role to perform this task.
Procedure
Open the External Storage window.
In the Hitachi Command Suite:
On the Resources tab, click Storage Systems, and then expand All Storage Systems.
Expand the target storage systems, right-click External Storage, and then select System GUI.
In Device Manager - Storage Navigator:
Click Storage Systems, and then expand the Storage Systems tree.
Click External Storage.
On the External Storage Systems tab, click the link for an external system.
On the External Path Groups tab, select a path group.
Click Disconnect External Storage Systems.
In the Disconnect External Storage Systems window, review the volumes that will be disconnected, then click Apply.
In the Confirm window, click Apply again.
When you finish the procedure, external volume’s status displays as Cache Destage, even if there is no data left in the cache. You can click Refresh View to update the status. When processing is completed, the volumes’ status changes to Disconnect.
