Managing RAID
Modifying tier redundancy, or adding or removing disks can cause data to be unevenly distributed across disks. A RAID rebalance
redistributes data over disks in a disk folder.
Rebalance RAID
Rebalancing RAID redistributes data over the disks according to the Storage Type. Rebalance the RAID after releasing a disk from a disk
folder, when a disk fails, or after adding a disk.
Steps
1. If the Storage Manager Client is connected to a Data Collector, select a Storage Center from the Storage view.
2. Click the Storage tab.
3. In the Storage tab navigation pane, select Disks.
4. Click Rebalance RAID.
The RAID Rebalance dialog box opens. If a RAID rebalance is needed, the dialog box shows RAID rebalance options.
5. Select Perform RAID Rebalance immediately.
6. Click OK.
Cancel a RAID Rebalance
Cancel a RAID rebalance to stop an on-going RAID rebalance. Cancelling a RAID rebalance does not cancel the need to rebalance. You will
still be prompted to rebalance RAID.
