SCSI over IP Protocol (SIPP)

Libraries can function in SIPP mode or non-SIPP mode, but not both. A library in SIPP mode looks the
same as a library that is not in SIPP mode, except for the absence of the SCSI HBA and its cable, and the
absence of any e1200–160 interface controllers. The mode is recognized when the library is powered-on.
If a library is equipped with SIPP functionality, it transports SCSI commands through the interface
controller's FC port to the library's robotics controller Ethernet port. SIPP delivers the error handling
and retry capabilities of a TCP/IP connection.
SIPP is compatible with e2400–260, e2400–FC 2G, and e2400–FC 4G interface controllers. It is not
compatible with e1200–160 interface controllers. If there is more than one interface controller in the
library, the "master" interface controller receives the move commands. The Interface Manager assigns as
"IC SIPP Master" the first interface controller that it detects during the first boot of the library after SIPP is
enabled. Use Command View TL to find out which IC is the IC SIPP Master.

Interface Manager card

The HP StorageWorks Interface Manager is a management card designed to consolidate and simplify
the management of multiple FC interface controllers installed in the library. It also provides SAN-related
diagnostics and management for library components including interface controllers, drives, and robotics.
The Interface Manager card, in conjunction with HP StorageWorks Command View TL software, provides
remote management of the library via a serial, telnet, or web-based graphical user interface.
In a SIPP-enabled library, the Interface Manager card is located in the bottom-most slot in the card cage;
otherwise, it is located to the right of the cluster controller in drive cluster 0
