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.
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.
