lpfc_discovery_threads | 32 | 1 | 64 | Specifies the maximum | No |
|
|
|
| number of 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. |

|
|
|
|
| prevents the driver from |
|
|
|
|
| creating any virtual ports. |
|
|
|
|
| When enabled (set to 1) it |
|
|
|
|
| enables you to create and |
