Library & Drive Code Update (Feature Code 0500); Location Coordinates - IBM System Storage TS3310 Setup And Operator Manual

Control Path Failover
A control path is a logical path into the library through which a server sends
standard SCSI Medium Changer commands to control thelogical library. Additional
control paths reduce the possibility that failure in one control path will cause the
entire library to be unavailable. Use of the control path failover feature further
reduces that possibility.For more information, see "Using Multiple Control Paths"
on page 2-2).
Data Path Failover
Data Path Failover is designed to provide a failover mechanism in the IBM device
driver, which enables you to configure multiple redundant paths in a SAN
environment. In the event of a path or component failure, the failover mechanism
is designed to automatically provide error recovery to retry the current operation
using an alternate, pre-configured path without aborting the current job in
progress. This allows you flexibility in SAN configuration, availability, and
management.For more information, see "Using Multiple Data Paths for Data Path
Failover" on page 2-3.
Library & Drive Code Update (Feature Code 0500)
Order feature code 0500, Library and Drive Code Update, if you would like an
IBM Service Representative dispatched to your location to update your library and
drive firmware.

Location Coordinates

A numbering system is used to identify components of the library. The library
location coordinates contain the following digits: [Module],[Column],[Slot]. The
figure below illustrates how a library with a control module and an expansion
module are numbered.
