Storage instance-specific persistent parameters
A
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 PCI function number for the port where you want to set the log level.
-coalesce | c Sets the coalesce flag. Possible values are on or off.
-l latency Sets the latency monitor timeout value. Latency can be between 0 to 225
microseconds. A latency value of 0 disables latency monitor timeout
interrupt.
-d delay 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.
NOTE
You can also modify vHBA Interrupt Coalescing parameters through HCM. Refer to the Brocade
Adapters Administrator’s Guide for details.
