Driver for VMware ESX Configuration Parameters
All HBA-specific parameters have an lpfcX_ prefix (where X is the driver instance number); e.g., setting
lpfc0_lun_queue_depth= 20 makes 20 the default number of maximum commands which can be sent to
a single logical unit (disk) for lpfc instance 0.
Dynamic parameters do not require the driver to be unloaded and reloaded for changes to take effect.
lpfc_use_adisc 0 0=Off 1=On Sends ADISC instead of
PLOGI for device discovery or RSCN.
