Removing Storage Arrays
You can remove a storage array from the list of managed arrays if you no longer want to manage it from
a specific storage management station. Removing a storage array does not affect the storage array or its
data in any way. Removing a storage array only removes it from the list of storage arrays displayed in the
Devices tab of the EMW.
To remove the storage array:
1. In the EMW, select the Devices tab and select the relevant managed storage array.
2. Select Edit → Remove → Storage Array.
You can also right-click on a storage array and select Remove → Storage Array.
A message prompts you to confirm if the selected storage array is to be removed.
3. Click Yes.
The storage array is removed from the list.
Enabling Premium Features
You can enable premium features on the storage array. To enable the premium features, you must obtain
a feature key file specific to the premium feature that you want to enable from your storage supplier.
To enable premium features:
1. From the menu bar in the AMW, select Storage Array → Premium Features.
The Premium Features and Feature Pack Information window is displayed.
2. Click Use Key File.
The Select Feature Key File window opens, which lets you select the generated key file.
3. Navigate to the relevant folder, select the appropriate key file, and click OK.
The Confirm Enable Premium Fetaures dailog is displayed.
4. Click Yes.
The required premium feature is enabled on your storage array.
5. Click Close.

Displaying Failover Alert
You can change the failover alert delay for a storage array. The failover alert delay lets you delay the
logging of a critical event if the multi-path driver transfers virtual disks to the non-preferred controller. If
the multi-path driver transfers the virtual disks back to the preferred controller within the specified delay
period, a critical event is not logged. If the transfer exceeds this delay period, then a virtual disk-not-on-
preferred-path alert is issued as a critical event. You can also use this option to minimize multiple alerts
when more than one virtual disk fails over because of a system error, such as a failed host adapter. For
more information, see the online help topics.
