Changing the master controller
One interface controller is assigned by the Interface Manager card as the master controller. Only the
master controller is designated to send commands to the library robotics controller. If multiple interface
controllers are present, Command View TL software, through the Cabling View, can be used to determine
which one is acting as the master. Changing the master controller requires a service-level password and
command using the CLI (Telnet or serial). The commands are:
SERVICE L&TTPASSWORD
SET IPCONNECTION INTERFACE MASTER X
where L&TTPASSWORD is the Library and Tape Tools (L&TT) password obtained from the web site
http://www.hp.com/support/tapetools and X is the interface controller number. You can find the
interface controller number by using the SHOW INTERFACE INFO ALL CLI command.
Whenever the master controller is replaced in the library, the following manual service steps are
necessary:
1. Remove all partitions.
2. Remove all host maps.
3. Log in to the CLI and obtain service-level access.
4. Use the SET IPCONNECTION INTERFACE MASTER X command to make a particular interface
controller the master. Currently, the Interface Manager card does not automatically fail over an
interface controller, even if the previous master interface controller is missing.
5. Reconfigure maps and partitions.
