San Device Discovery Support - IBM E16RMLL-I - Tivoli Storage Manager Implementation Manual

In Example 16-20, we define the required paths.
Example 16-20 Storage agent path definition to the shared tape drives
tsm: ATLANTIC>d
cont> library=3582_shared device=mt0.0.0.2
ANR1720I A path from STA_DIOMEDE to 3582_SHARED DR00 has been defined.
tsm: ATLANTIC>
cont> library=3582_shared device=mt1.0.0.2
ANR1720I A path from STA_DIOMEDE to 3582_SHARED DR01 has been defined.
We review our settings using the query path command, which reveals all defined
paths, as shown in Example 16-21.

16.4 SAN device discovery support

With Tivoli Storage Manager V5.3 and later, the server and Storage Agent option
sandiscovery, if specified, means that the server will perform SAN discovery
during both server initialization and if the device path has changed.
Essentially, if the SAN device identification has been changed due to SAN
environmental changes, such as device, cabling changes, or bus resets, the
server or Storage Agent will discover these changes during server or Storage
Agent startup or when accessing the paths during operations with the drives and
will perform the necessary changes to the path definition, based on the drive
serial number. Thus, the path will not go offline. Instead, it stays online and
available for the operation.
On Windows platforms this option is set by default. On other platforms enable
SAN discovery using the SANDISCOVERY on option in the server options file
