Renaming a disk pool
Use the Rename option to change the name of a disk pool when the current name is no longer meaningful.
Keep these guidelines in mind when you rename a disk pool:
• A disk pool name can consist of letters, numbers, and the special characters underscore (_), hyphen (-), and pound (#). If you choose
any other characters, an error message is displayed. You are prompted to choose another name.
• Limit the name to 30 characters.
• Use a unique, meaningful name that is easy to understand and remember.
• Do not use arbitrary names or names that may quickly lose their meaning in the future.
• If you choose a disk pool name that is already in use, an error message is displayed. You are prompted to choose another name.
To configure alert notifications for a disk pool:
1. In AMW, select the Storage & Copy Services tab.
2. Select the disk pool.
3. From the menu bar, select Storage > Disk Pool > Rename. Alternatively, right-click on the disk pool and select Rename.
The Rename Disk Pool dialog is displayed.
4. Type a new name in Disk pool name.
5. Click OK.
Configuring alert notifications for a disk pool
You can configure the MD storage manager to send alert notifications when the unconfigured (free) capacity of a disk pool is reaching a
specified percentage. You can modify the alert notification settings after creating a disk pool.
To configure alert notifications for a disk pool:
1. In AMW, select the Storage & Copy Services tab.
2. Select the disk pool.
3. From the menu bar, select Storage > Disk Pool > Change > Settings.
The Change Disk Pool Settings dialog is displayed.
4. In the Change Warning Thresholds area, select the check box corresponding to a critical warning notification.
You also can select the check box corresponding to an early warning notification.
NOTE: The early warning notification is available only after you select the critical warning notification.
5. Select or type a value to specify a percentage of usable capacity.
When the unconfigured (free) capacity in the disk pool reaches the specified percentage, an alert notification in the form of e-mail
messages and SNMP trap messages are sent to the destination addresses that are specified in the Configure Alerts dialog. For more
information about how to specify the destination addresses, see Configuring Alert Notifications.
6. Click OK.
Adding unassigned physical disks to a disk pool
Use the Add Physical Disks (Capacity) option to increase the free capacity of an existing disk pool by adding unassigned physical disks.
After you add unassigned physical disks to a disk pool, the data in each virtual disk of the disk pool is redistributed to include the additional
physical disks.
NOTE: Keep these guidelines in mind when you add physical disks to a disk pool:
• The status of the disk pool must be Optimal before you can add unassigned physical disks.
• You can add a maximum of 12 physical disks to an existing disk pool. However, the disk pool cannot contain more physical disks than
the maximum limit for a storage array.
• You can add only unassigned physical disks with an Optimal status to a disk pool.
• The data in the virtual disks remains accessible during this operation.
To add unassigned physical disks a disk pool:
1. In AMW, select the Storage & Copy Services tab.
2. Select the disk pool.
3. From the menu bar, select Storage > Disk Pool > Add Physical Disks (Capacity).
