Note: System managed tape encryption and library managed tape encryption are
transparent to one another. A tape encrypted using system managed
encryption may be decrypted using library managed encryption, and vice
versa, provided both have access to the same EKM keystore.
• Encryption policy ( library-managed encryption )
– Encrypt All (default) — All tape cartridges loaded into the tape drive are
encrypted.
– Internal Label - Selective Encryption — This option is used only for Symantec’s
Veritas NetBackup™.
– Internal Label - Encrypt All — This option is used only for Symantec’s Veritas
NetBackup™.
• Advanced Encryption Settings — The purpose of these advanced encryption
settings is to allow only IBM Support personnel (under the direction of the drive
development team) to provide a solution to an unforeseen problem or to support a
unique configuration. These options are not intended for use by the customer
without the guidance of IBM Support.
To determine whether a cartridge is encrypted, use Configure Library
→
Library
Map and select the cartridge. The screen displays whether the cartridge is encrypted,
not encrypted, or unknown.
Click Submit to transfer the settings to the library. A dialog message is displayed
when the settings have been updated successfully.
Click Refresh to read the current settings from the library.
Configuring Date and Time Settings
Figure 4-44. Date and Time settings screen
Use Configure Library
→
Date and Time to configure the date and time settings
using one of three methods. The date and time can be automatically updated using a
remote NTP time server over the network. Alternatively, the date and time can be
synchronized with the clock on your host computer. And lastly, that date and times
can be set manually.
The TS2900 Tape Autoloader communicates with an NTP server with the following
conditions:
• client-server basis operation
• UDP (User Datagram Protocol) to access the NTP server
• does not use authentication keys
• library polling is every 12 hours
