Figure 187. LME: Drive Encryption Settings window
To change encryption settings for a drive:
1. Select the drives that you want to work with.
Notes:
a. Only drives that are encryption-capable are displayed in the drives
list box. In order to determine if a drive is encryption-capable, the
LM must receive a DRIVE_STATUS message from the drive. This
normally occurs when a 3592 drive initializes with the Library
Manager. If a drive has not communicated its encryption capability
to the LM via a DRIVE_STATUS message, then it will NOT be
displayed in the drives list box.
b. A drive may be encryption-capable but not have encryption enabled.
The column in the drives list box that is titled En will display a Y if
the drive has encryption enabled and a N if the drive does NOT
have encryption enabled.
c. Each drive's current encryption settings are displayed in the drives
list box. The operator can obtain a fresh display of one or more
drives by requesting a Get VPD (Get Vital Product Data), which
sends a request to the drive to send a DRIVE_STATUS message back
to the Library Manager.
2. Select the desired encryption settings.
