Metrocluster with 3PAR Remote Copy A.01.00 Release Notes

Fixes for A.01.00 in the March 2013 Patch Release

• QXCR1001259829

When the Remote Copy volume group is configured with asynchronous periodic mode, and

if the RESYNC_WAIT_TIMEOUT parameter is configured, then during the package startup

Metrocluster must synchronize the non-current data. Currently, Metrocluster does not synchronize

the data, and allows the package to startup with non-current data even if the

RESYNC_WAIT_TIMEOUT parameter is configured.

• QXCR1001260884

Metrocluster uses HP 3PAR CLI commands to manage the Remote Copy. During failover,

Metrocluster issues CLI commands to swap the replication role and reverse the direction of

replication. If the CLI command startrcopygroup fails, Metrocluster logs the failure and

continues the package startup. It does not retry executing the startrcopygroup command.

• QXCR1001267860

The Metrocluster module script uses the grep command without strict pattern matching to

parse the 3PAR CLI command output. The output is parsed to check the correctness of the

DC1_RC_TARGET_FOR_DC2 and DC2_RC_TARGET_FOR_DC1 parameters. The pattern

matching is not strict. Hence when the virtual volume name is a substring of Remote Copy

volume groupname, the virtual volume name is added to the target name. Therefore, the string

equality check for configured target name and parser output fails, which results in the package

configuration error.

Known problems and workarounds

The following is a known issue with Metrocluster with 3PAR Remote Copy A.01.00:

• QXCR1001319757

When the name of the Remote Copy Volume Group contains “.”, the cmcheckconf and

cmapplyconf commands of Metrocluster 3PAR package fails.

• QXCR1001332281

The Metrocluster with 3PAR during Inform OS cli invocation does not export root user home

directory path if the CLI version 2.3.1 MU5 Patch35, 3.1.1 MU3 Patch27, 3.1.2 MU3 Patch16

is installed, Metrocluster packages fails to start. Do the following on all the Metrocluster

packages nodes:

1. Move the existing symbolic link to the 3PAR cli from “cli” to “3parcli”.

For Example:

# mv cli 3parcli

2. Create a new file named cli in /usr/bin directory and add the following code snippet:

#!/bin/bash

_uid="$(id -u)"

if [[ $_uid -eq 0 ]];then

export HOME=/root

/usr/bin/3parcli $@

3. Set the appropriate execution permission in the/usr/bin/cli file.
