lpfc_discovery_threads

64

Specifies the maximum number of

No

 

 

 

 

ELS commands that can be

 

 

 

 

 

outstanding for a discovery.

 

 

 

 

 

Note: The discovery_threads

 

 

 

 

 

parameter will default to a value of

 

 

 

 

 

64 for private loop topologies

 

 

 

 

 

regardless of the configured value.

 

 

 

 

 

If there are multiple ports

 

 

 

 

 

configured on the host the value of

 

 

 

 

 

64 will only be used for those ports

 

 

 

 

 

that are connected in a private

 

 

 

 

 

loop topology. The configured

 

 

 

 

 

value will be used for all other

 

 

 

 

 

ports.

 

 

 

 

 

Note: On the VMware ESX Server

 

 

 

 

 

only, range is 30 - 64. The default

 

 

 

 

 

is erroneously set to 1. Set this

 

 

 

 

 

parameter to a valid value. If you

 

 

 

 

 

do not, when you change any

 

 

 

 

 

parameter value, the following

 

 

 

 

 

error message may be displayed:

 

 

 

 

 

“Driver Parameter ‘discovery-
