Figure 101. Create Disk Folder
3 From the list of unmanaged disks, select disks to be included in the new disk folder.
Note The redundancy level of each disk tier is selected automatically based upon the size
of disks in the tier. By default, dual redundancy is selected for any tier with a drive
greater than 900GB in size.
4 Click Continue. System Manager displays the disks you selected, and asks you to
choose one or more disks to be a hot spare. The hot spare can replace a failing disk.
The spare must be as large as the largest disk in the folder so that it can replace any
disk. By default, if there are disks of differing sizes, Storage Center selects the largest
disk, or one of them. You cannot create a disk folder without a spare.
5 Click Continue. Enter a folder name. Enter any notes (up to 255 characters).
6 Click Create Now. The Folder is created.
Deleting a Disk Folder
Before a disk folder can be deleted, it must be empty of disks. Release or delete all disks
within a folder before you delete the disk folder.
