Managing Data Redundancy
Manage data redundancy by modifying tier redundancy, creating Storage Types, or rebalancing RAID.
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, a disk fails, or adding a disk.
1. Select a Storage Center from the Storage view. (Data Collector connected Storage Manager Client only)
2. Click the Storage tab.
3. In the Storage tab navigation pane, select the Disks node.
4. Click Rebalance RAID. The RAID Rebalance dialog box appears. 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. After canceling, Storage Manager will still recommend a RAID
rebalance.
