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.
