Secure Disk Pools
You can create a secure disk pool from security capable physical disks. The physical disks in a secure disk pool become
security enabled. Read access from and write access to the physical disks is only available through a RAID controller
module that is configured with the correct security key.
CAUTION: Possible loss of data access – When a disk pool is secured, the only way to remove security is to delete
disk pool. Deleting the disk pool deletes all of the data in the virtual disks that comprise the disk pool.
Whenever the power is turned off and turned on again, all of the security-enabled physical disks change to Security
Locked status. In this status, the data is inaccessible until the correct security key is provided by a RAID controller
module. You can view the Physical Disk Security status of any disk pool in the storage array from the
Disk Pool
Properties
dialog. The following status information is reported:
•
Security Capable
•
Secure
The following table provides a description of the security properties status of a disk pool.
