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.
