114 Setting up I/O fencingAdditional I/O fencing informationTesting a disk with existing keysIf the utility detects that a coordinator disk has existing keys, you see a messagethat resembles:There are Veritas I/O Fencing keys on the disk. Please make surethat I/O Fencing is shut down on all nodes of the cluster beforecontinuing.******** WARNING!!!!!!!! ********THIS SCRIPT CAN ONLY BE USED IF THERE ARE NO OTHER ACTIVE NODES IN THE CLUSTER! VERIFY ALL OTHER NODES ARE POWERED OFF ORINCAPABLE OF ACCESSING SHARED STORAGE.If this is not the case, data corruption will result.Do you still want to continue : [y/n] (default: n) yThe utility prompts you with a warning before proceeding. You may continue aslong as I/O fencing is not yet configured.About VXFEN tunable parametersOn each node, edit the file /kernel/drv/vxfen.conf to change the value of thevxfen driver tunable global parameter, vxfen_max_delay and vxfen_min_delay.You must restart the system to put change into effect.Table 5-4 describes tunable parameters for the VXFEN driver.Table 5-4vxfen Parametervxfen_debug_szvxfen_max_delayandvxfen_min_delay(See below.)VXFEN tunable parametersDescription and Values: Default, Minimum, and MaximumSize of debug log in bytes■ValuesDefault: 65536Minimum: 65536Maximum: 256KIn the event of a network partition, the smaller cluster delaysbefore racing for the coordinator disks. The time delayed allows alarger sub-cluster to win the race for the coordinator disks. Thevxfen_max_delay and vxfen_min_delay parameters define thedelay in seconds.
Setting up I/O fencingAdditional I/O fencing information115Table 5-4vxfen Parametervxfen_max_delayvxfen_min_delayVXFEN tunable parametersDescription and Values: Default, Minimum, and MaximumSpecifies the maximum number of seconds that the smaller subclusterwaits before racing with larger clusters for control of thecoordinator disks.This value must be greater than the vxfen_min_delay value.■ValuesDefault: 60Minimum: 0Maximum: 600Specifies the minimum number of seconds that the smaller subclusterwaits before racing with larger clusters for control of thecoordinator disks. This value must be smaller than thevxfen_max_delay value.■ValuesDefault: 1Minimum: 0Maximum: 600Example of implementing the vxfen_max_delay parameterThe following is an example of changing the vxfen_max_delay parameter.The default file /kernel/drv/vxfen.conf looks like this:## VXFEN configuration file#name="vxfen" parent="pseudo" instance=0 vxfen_debug_sz=65536 vxfen_max_delay=60 vxfen_min_delay=1;Change the min_delay value to 30.## VXFEN configuration file#name="vxfen" parent="pseudo" instance=0 vxfen_debug_sz=65536 vxfen_max_delay=60 vxfen_min_delay=30;Close and save the file. For the changes to take effect, either restart the system, or reconfigure the VXFEN module.See “Configuring the VXFEN parameters” on page 115.Configuring the VXFEN parametersFor the parameter changes to take effect, reconfigure the VXFEN module.
