SANDISCOVERY
The SANDISCOVERY option specifies whether the IBM Spectrum® Protect 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
The IBM Spectrum Protect 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.
Restriction: If tape devices are zoned together with disk devices, the
SAN discovery operation skips discovery of tape devices when the first detected device is a disk
device from a port on a Fibre Channel. If all tape devices are zoned with disk devices, the tape
devices are not found when you issue the QUERY SAN command. The following
messages are
displayed:
ANR2034E QUERY SAN: No match found using this criteria.
ANS8001I Return code 11.
If
the first device on the device mapping from the Fibre Channel port is a tape, either a full or
partial list of tape devices is displayed when you issue the QUERY SAN command.
The number of tape devices displayed depends on how the tape devices are zoned.Syntax
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 IBM Spectrum Protect 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 IBM Spectrum Protect server is not able to open a device, a message is issued and the path to the device is taken offline.
