Configuration: About Your Storage Array 75

Adding/Editing a Comment to an Existing Storage Array

A descriptive comment, with an applicable storage array name, is a helpful

identification tool. You can add or edit a comment for a storage array in the

EMW only.

To add or edit a comment:

In the EMW, select the

Devices

tab and select the relevant managed

storage array.

Select

Edit



Comment

The

Edit Comment

dialog is displayed.

Type the 60-character comment.

Click

This option updates the comment in the table view and saves it in your local

storage management station file system. The comment does not appear to

administrators who are using other storage management stations.

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 simply removes it from the list of storage arrays

that appear in the drop-down list in the Array Selector. If a storage array is

accidentally removed, it can be added again. See "Adding Storage Arrays" on

page 68.

You can remove the storage array only from the EMW.

To remove the storage array:

In the EMW, select the

Devices

tab and select the relevant managed

storage array.

Select

Edit



Remove



Storage Array

A message prompts you for a confirmation for the removal of the selected

storage array.

To remove the storage array, click

Yes
