Connection paths
For the purpose of the software configuration, Examples #1 and #2 are identical because only one
physical path exists between the Profiler appliance and the SAN (the single Profiler port connecting to
the single SAN device port). All other configurations create multiple paths to a single LUN. Although each
path has a unique block device (
/dev/sd?
) created, they all share the same LUN on the SAN device.
Therefore, only one block device has to be used for updating it. Concurrent use of these block devices
will lead to data corruption.
When multiple-path connections to the same LUN are detected, the Profiler appliance automatically
enables the failover.
Preparing to configure the software
After installing the FC HBA hardware and verifying the Link LED is lit on one (single port connection) or
both (dual ports connection) of the Profiler FC HBA ports, allocate a Logical Unit Number (LUN) for the
Profiler appliance to use on the SAN device. The port status can be checked by running the following
command as root on the Profiler appliance.
