HP 3PAR Cluster Extension Software 2.00.00 Release Notes for Linux (5697-2049, June 2012)

Notes

• The package start will fail on the alternative nodes for any scenario where the package (with

volume group module configured) does not get a chance to halt and the cluster status of

previous owner node is not failed. Since the volume group tags would be left, they have to

be cleared manually (see package logs for the steps). This is intentional to bring manual

intervention to avoid any data corruption issues. For more information see Managing HP

Serviceguard for Linux on the HP High Availability website http://docs.hp.com/en/ha.html.

• Manual intervention is required to bring the package online on the cluster nodes in the other

data center when the package failover is triggered manually (owning node is alive) in the

state when HP 3PAR Remote Copy link is down. See the package logs for the steps to bring

the package online.

• For achieving automated failover to next preferred node in case of disk access loss at the

package owning node, you must set the HP Serviceguard cluster software property in the

package configuration file service_fail_fast_enabled to yes. For more information

see Managing HP Serviceguard for Linux on the HP High Availability website http://

docs.hp.com/en/ha.html.

• After you install a permanent license key on a cluster node, ensure the instant-on license is

removed. For instructions, see Removing an instant-on license key in the HP 3PAR Cluster

Extension Software Installation Guide.
