• Initialize: Fast — Updates the metadata on the physical disks so that all the disk space is available
for future write operations. The initialize option can be completed quickly because existing
information on the physical disks is not erased, although future write operations overwrites any
information that remains on the physical disks.
• Initialize: Full — All existing data and file systems are erased.
NOTE: The Initialize: Full option is not applicable for PERC H330 controllers.
• Check Consistency
• Encrypt Virtual Disk — Encrypts the virtual disk drive. If the controller is encryption capable, you
can create, change or delete the security keys.
NOTE: The Encrypt Virtual Disk option is available only if the virtual disk is created using the
Self-Encrypting Drive (SED) drives.
• Manage Dedicated Hotspares — Assign or unassign a physical disk as a dedicated hot spare. Only
