Array erweitern - Problem

Expanding an array

You can increase the storage space on an array by adding physical drives. Any drive that you want to
add must meet the following criteria:

• It must be an unassigned drive.
• It must be of the same type as existing drives in the array (for example, SATA or SAS).
• It must have a capacity no less than that of the smallest drive in the array.

When you want to expand an array, allow about 15 minutes per gigabyte for the expansion to be completed. During this time, the controller cannot perform any other expansion or migration. Performance might be degraded slightly during the expansion, depending on the Expand Priority setting ("Setting the rebuild priority or expand priority" on page 18). To minimize any effect on normal server operations, expand an array during periods of low server use.

To expand an array:
1. Back up all data on the array. Although array expansion is unlikely to cause data loss, observing this precaution provides extra data security.
2. Confirm that the cache battery is connected and fully charged.
3. In the Logical Configuration View panel, highlight the array, and then press the Enter key.
4. In the Array Options menu, highlight the Expand Array option, and then press the Enter key.
The screen displays three panels (Expand Array, Physical Drives, and Expand Existing Array), and the highlight moves to the Expand Array panel.
5. Highlight the Assign Drive option, and then press the Enter key. The highlight moves to the Physical Drives panel.
6. Highlight a physical drive that you want to add to the array, and then press the Enter key. (For optimum use of drive capacity, select a drive that has the same capacity as other drives in the array.) The highlight returns to the Expand Array panel.
7. (Optional) Repeat steps 5 and 6 to add more drives.
