Behavior of Unavailable Fibre Channel Ports
The Library Controller FC Port 2 is unavailable and supports a limited set of commands until you activate it with a hardware activation file.

Port 2 is unavailable until you install the redundant control paths (multi-port) hardware activation file. See the SL4000 Library Guide for more information. The library can receive commands on an unavailable port. However, the library only fully supports the following commands on an unavailable port:

-
Sets the sense key to Not Ready (02h), ASC to 04h, and ASCQ to 0ch — Not Ready, Logical Unit Not Accessible, Target Port in Unavailable State
