Rekeying all disk LUNs manually
2
4. Click Add.
The Add Disk LUNs dialog box displays. This dialog box includes a table of all LUNs in the
storage device that are visible to the hosts.
5. Click Re-keying Details.
The LUN Re-keying Details dialog box displays. The dialog box contains the following
information:
• Key ID: The LUN key identifier.
• Key ID State: The state of the LUN rekeying operation.
• Encryption Algorithm: The algorithm of the LUN rekeying operation.
• Re-key Session Number: The session number of the LUN rekeying operation.
• Re-key Role: The role of the LUN rekeying operation.
• Re-key State: The state of a manual LUN rekeying operation. Options are:
• Read Phase
• Write Phase
• Pending
• Disabled
• Block Size: The block size used on the LUN.
• Number of Blocks: The number of blocks written.
• Current LBA: The Logical Block Address (LBA) of the block that is currently being written.
• Re-key Completion: The status of the LUN rekeying operation’s progress.
Viewing the progress of manual rekey operations
To monitor the progress of manual rekey operations, complete these steps:
1. Select Configure > Encryption from the menu task bar to display the Encryption Center
dialog box (Refer to Figure 1 on page 14).
1. Select an encryption group from the Encryption Center Devices table, then select Group >
Re-Key Sessions from the menu task bar.
The Re-Key Sessions Status dialog box displays, which enables you to check on the status of
each LUN that is being rekeyed within an encryption group (Figure 73).
