Managing instance-specific persistent parameters

Use BCU commands to modify instance-specific persistent parameters for storage drivers. For
details on using these commands, refer to the Brocade Adapters Administrator's Guide.
vHBA Interrupt parameters
Following is an example of modifying the vHBA interrupt parameters.
bcu vhba --intr <pcifn-id> <-coalesce | -c> {on|off} [<-l <usecs> <-d <usecs>
where:
pcifn-id
-coalesce | c
-l latency
-d delay
NOTE
You can also modify vHBA Interrupt Coalescing parameters through HCM. Refer to the Brocade
Adapters Administrator's Guide for details.

Adapter instance-specific parameters (continued)
Parameter Default Value
bfa#-port-speed 0
bfa#-port-topology 1
bfa#-port-enable 0
PCI function number for the port where you want to set the log level.
Sets the coalesce flag. Possible values are on or off.
Sets the latency monitor timeout value. Latency can be between 0 to 225
microseconds. A latency value of 0 disables latency monitor timeout
interrupt.
Sets the delay timeout interrupt value. A delay can be between 0 to 1125
microseconds. A delay value of 0 disables the delay timeout interrupt.
