Unisphere and Unisphere Central 2020 R1 Administrator's Guide

Managing Disks and Disk Folders

Manage disks by adding new disks and organizing disks in disk folders.

Add disks and enclosures to accommodate greater data needs. The supported number of enclosures attached to Storage Center depends on the controller and enclosure being used.

When adding disks be aware of the following.

• After disks are added, additional space may not be immediately available. Make sure to allow enough time for Unisphere to allocate space for writes.
• Create a new disk folder only to address specific application program requirements. Creating a second disk folder may cause storage to be used inefficiently.
• Data cannot be written to unassigned disks.
• The Assigned disk folder was created during initial configuration of the Storage Center. Managing unassigned disks means moving the disk to a managed disk folder.
• When Unisphere detects self-encrypting drives (SEDs) that are Federal Information Processing Standard (FIPS) 140-2 certified, it formats the drives for Secure Data use.
  • If Self-Encrypting Drives is licensed, disks will be managed in a Secure Data folder.
  • If Self-Encrypting Drives is not licensed, disks will be treated as unsecured drives, but may be upgraded to Secure Data status if a license is purchased in the future.
