NOTE:
If you have not created a security key for the storage array, the Create
Security Key option is active. If you have created a security key for the storage
array, the Create Security Key option is inactive with a check mark to the left. The
Change Security Key option, the Save Security Key option, and the Validate Security
Key option are now active.
The Secure Physical Disks option appears in the Disk Group menu. The
Secure Physical Disks option is active if these conditions are true:
• The selected storage array is not security enabled but is comprised entirely
of security capable physical disks.
• The storage array contains no snapshot base virtual disks or snapshot
repository virtual disks.
• The disk group is in an Optimal state.
• A security key is set up for the storage array.
NOTE:
The Secure Physical Disks option is inactive if these conditions are not true.
The Secure Physical Disks option is inactive with a check mark to the left if
the disk group is already security enabled.
The Create a secure disk group option appears in the Create Disk Group
Wizard - Disk Group Name and Physical Disk Selection dialog. The Create a
secure disk group option is active only when these conditions are met:
• A security key is installed in the storage array.
• At least one security capable physical disk is installed in the storage array.
• All of the physical disks that you selected on the Physical tab are security
capable physical disks.
You can erase security-enabled physical disks so that you can reuse the drives
in another disk group or in another storage array. When you erase security-
enabled physical disks, ensure that the data cannot be read. When all of the
physical disks that you have selected in the Physical pane are security enabled,
and none of the selected physical disks is part of a disk group, the Secure
Erase option appears in the Physical Disk menu.
The storage array password protects a storage array from potentially
destructive operations by unauthorized users. The storage array password is
independent from self encrypting disk, and should not be confused with the
pass phrase that is used to protect copies of a security key. However, it is good
practice to set a storage array password
