Check the Status of a RAID Rebalance
The RAID Rebalance displays the status of an in-progress RAID rebalance and indicates whether a rebalance is needed.
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, click the Disks node.
4. Select Rebalance RAID. The RAID Rebalance dialog box shows the status of a RAID rebalance.
Managing Storage Types
Storage Types determine how Data Progression moves data within a disk folder. Each disk folder has a corresponding Storage Type.
NOTE: Modifying tier redundancy requires a RAID rebalance to be completed, and should not be performed unless
sucient free disk space is available within the disk folder.
Create a Storage Type
Creating a Storage Type sets the redundancy level for each tier and assigns the Storage Type to a disk folder.
Prerequisite
SCv2000 does not support creating new Storage Types.
About this task
NOTE: Do not assign multiple Storage Types to one disk folder. Data Progression may not perform as intended with
multiple Storage Types assigned to one disk folder.
Steps
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, click Storage Types.
4. Click Create Storage Type. The Create Storage Type dialog box opens.
5. Select a disk folder from the Disk Folder drop-down menu.
6. Select a redundancy type.
• To create a redundant Storage Type, select Redundant.
• To create a non-redundant Storage Type, select Non-Redundant.
7. For redundant Storage Types, modify the redundancy for each tier as needed.
• For single-redundant RAID levels, select Redundant.
• For dual-redundant RAID levels, select Dual Redundant.
8. Select a Datapage Size.
9. Click OK.
Modify Tier Redundancy
Modify tier redundancy to change the redundancy level for each tier in a Storage Type. After modifying tier redundancy, a RAID
rebalance is required to move data to the new RAID levels.
About this task
NOTE: Do not modify tier redundancy if there is insucient space in the tier for a RAID rebalance.
Steps
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, expand Storage Types then click a Storage Type.
4. Click Modify Tier Redundancy. The Modify Tier Redundancy dialog box opens.
