Configuring Storage

4 Repeat for all the tiers you want to modify.
5 Click OK.
If any of the modified tiers contain any disks, perform a RAID Rebalance in order to
complete the tier redundancy modification.
Figure 94. Modify Redundancy Rebalance
If the system determines that there is sufficient disk space to rebalance data across drives,
a rebalance is started automatically. Refer to Rebalancing RAID on page 122.
If there does not appear to be enough disk space available in the disk folder to allow for a
RAID Rebalance, the system asks you to add storage. Refer to Adding Disks to a Storage
Center System on page 116.

1 Select the disk folder. From the shortcut menu, select Configure Storage.
2 From the resulting window, select a Storage Class.
3 Click Remove Selected Class. The system warns you that before proceeding with
modification, it is advised that you contact Dell Support Services for assistance.
