Understand Device Numbering

When the driver is configured, there are various configuration parameters that rely upon

device numbers. This section explains the two levels of device numbering and how they

apply to specific configuration parameters.

The first level of device numbering is the driver instance number. This is the number that is

displayed in log messages to syslog or the console, for example: lpfcX. The adapCfg.h

configuration parameters that use lpfcXtY rely on X to be the driver instance number and Y

to be the FCP target number. This format is used to configure persistent binding. In

systems where adapters are moved around or changed, it is possible for the driver

instance number to exceed the number of adapters.

The second level of numbering is the SCSI controller number. This number is assigned by

the system for each Pseudo HBA driver it detects. It is typically in the special files created

to access each SCSI device: for example, /dev/dsk/cZt0d0s2.

Once these numbers are assigned, they stay the same between reboots if there are no

LightPulse hardware changes to the system.
