HP 3PAR Cluster Extension Software Release Notes for Linux (5697-1431, March 2012)

Enhancements

None.

Fixes

Issue: When a service is moved from one cluster node (Node A) to another cluster node (Node B)

resulting in a failover being triggered, a CLX resource must be online. If a CLX resource fails to

come online for some reason on Node B, entire service goes to the failed state on Node B and

the cluster does not relocate this service to the next preferred node (Node C) or to any other cluster

node. This is a known LVM tagging related problem. Please contact RHEL to resolve the tagging

issue..

Workaround: Disable and enable or start this service on a cluster node to recover from this state.

Prerequisites

• After you install a permanent license key on a cluster node, make sure the instant-on license

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

Extension Software Installation Guide.

• Coexistence of 3PAR Cluster Extension with EVA Cluster Extension and XP Cluster Extension

on the same system is not supported.

Installation instructions

NOTE: In RHEL, before starting CLX installation, HP 3PAR Inform CLI should be installed. The

default installation path of the HP 3PAR Inform CLI version 3.1.1 is mentioned as a value for the

variable INFORM_CLI_PATH in the file /usr/share/cluster/clx3par.sh for CLX to work

in a desired fashion. The default path of the HP 3PAR Inform CLI version 3.1.1 mentioned for the

variable INFORM_CLI_PATH is “/opt/3PAR/inform_cli_3.1.1/bin”. Based on the CLX support

matrix, if user wants to use any other version of the HP 3PAR Inform CLI or if user wants to install

the HP 3PAR Inform CLI in any other path other than the default path, then the variable

INFORM_CLI_PATH in the file /usr/share/cluster/clx3par.sh should be modified

accordingly for all the resource agents used for configuring the services.

In SLES, the INFORM_CLI_PATH needs to be updated in the file /usr/lib/ocf/resource.d/

heartbeat/CLX3PAR if HP 3PAR Inform CLI version other than 3.1.1 is installed in the system

or if HP 3PAR Inform CLI is installed in a different path other than the default path. This variable

INFORM_CLI_PATH needs to be updated when HP 3PAR Inform CLI is upgraded to a newer version

from the existing version in the system.

To enable parallel start of services configured with CLX resources in certain versions of RHEL, the

configuration steps that need to be followed are as follows:

• Make as many copies of CLX resource agent (that is "/usr/share/cluster/clx3par.sh”) as there

are services. Change the file names of these resource agents (clx3par.sh). For example,

if there are 3 resource agents, you can name them as clx3par1.sh, clx3par2.sh and

clx3par3.sh.

• From each service, call a unique CLX resource agent. There is no change in the content of the

resource agent (other than the INFORM_CLI_PATH in case user wants to install Inform CLI

version other than 3.1.1 or wants to install Inform CLI in a customized path).

For installation instructions, see HP 3PAR Cluster Extension Software Installation Guide.
