SANDISCOVERY

The SANDISCOVERY option specifies whether the Tivoli® Storage Manager SAN discovery function is enabled.

To use SAN discovery, all devices on the SAN must have a unique device serial number. When set to ON, the server completes SAN discovery in the following instances:

When the device path is changed
When the QUERY SAN command is issued

Using SAN discovery, the server can automatically correct the special file name for a device if it is changed for a specified tape device.

The Tivoli Storage Manager server does not require persistent binding with the SAN discovery function enabled. To display a list of devices that are seen by the server, you can issue the QUERY SAN command.

Parameters

ON: Specifies that the server completes SAN discovery when the device path is changed, or when the QUERY SAN command is issued.
OFF: Specifies that the server does not complete SAN discovery when the device path is changed, or when the QUERY SAN command is issued. If the Tivoli Storage Manager server is not able to open a device, a message is issued but the path that is associated with the device is not taken offline. This value is the default.
UNSCANNEDPATHOFF: Specifies that the server does not complete SAN discovery when the device path is changed, or when the QUERY SAN command is issued. If the Tivoli Storage Manager server is not able to open a device, a message is issued and the path to the device is taken offline.
