Customizing VMware HA Behavior

VMware HA attributes:

• das.isolationaddress[1..9] you can specify up to 10 isolation address. Default isolation address is the gateway of service console network
• das.usedefaultisolationaddress (ture|false, true by default)
• das.failuredetectiontime host monitoring, 15 seconds. If there are extra isolation address, increase value to 20 or greater.
• das.failuredectioninterval 1 second by efault
• das.defaultfailovehost takes precedence over failover host name in the policy. Only one candidate.
• das.isolationShutdownTimeout 300 second for host isolation VM to be shutdown will be powered off
• das.slotMemInMB if used, slot size is memory reservation plus VM memory overhead in the cluster.
• das.slotCPUInMHz if used, slot size is CPU reservation plus VM CPU overhead in cluster
• das.vmMemoryMinMB VM memory reservation value, 0 by default
• das.vmCPUMinMHz VM CPU reservation is not zero or not specified, the default value is 256MHz
• das.iostatsinterval VM Monitoring reset after 120 seconds. 0 will disable VM Monitoring.

Changing the attribute value in bold, requires disable/re-enable HA to take into effect.
