1 Metrocluster with 3PAR Remote Copy for Linux Version B.01.00.10 Release Notes Announcement HP Metrocluster with 3PAR Remote Copy for Linux is a High Availability (HA) HP product that integrates Metrocluster with HP 3PAR Storage Systems.
Support for Remote Copy volume group monitor In a Metrocluster 3PAR environment, Remote Copy volume group monitor provides the capability to monitor the status of the Remote Copy volume group used in a package. It sends notifications to the user via email, syslog, OPC, or console. The notifications are sent when: • There is a change in a Remote Copy volume group status. • The monitor cannot determine the Remote Copy volume group status.
array. The primary and backup volumes are resynchronized periodically when scheduled or when resynchronization is manually initiated through the syncrcopy command. If an area of the volume is written multiple times between two resynchronizations, then only the last write needs to be sent to the other storage array. Therefore, when using Remote Copy in asynchronous periodic mode, less data is transferred relative to the synchronous mode.
Supported volume managers with Metrocluster with 3PAR Remote Copy for Linux The following volume managers are supported with Metrocluster 3PAR Remote Copy for Linux. • LVM For the supported versions of the volume managers, see Serviceguard Disaster Recovery Products Compatibility and Feature Matrix (Metrocluster 3PAR Remote Copy) available at http:// www.hp.com/go/linux-serviceguard-docs.
NOTE: Starting Serviceuard for Linux A.11.20.20, you can use Persistent Reservations with Metrocluster for Linux when Device Mapper (DM) is enabled. For more information on the restrictions, see HP Serviceguard for Linux Certification Matrix available at http://www.hp.com/go/linux-serviceguard-docs.
NOTE: For more information on support, compatibility, and features of Metrocluster with 3PAR Remote Copy for Linux, see Serviceguard Disaster Recovery Products Compatibility and Feature Matrix (Metrocluster 3PAR Remote Copy) available at www.hp.com/go/linux-serviceguard-docs. To use Metrocluster with 3PAR Remote Copy for Linux, the following hardware and software must be installed and configured on each cluster node.
# rpm –i serviceguard-metrocluster-3parrc-B.01.00.00-0.rhel6.x86_64.rpm (RHEL 6.x only) For SLES: # rpm –i serviceguard-metrocluster-3parrc-B.01.00.00.00-0.sles11.x86_64.rpm The software will reside in the following directories: For Red Hat: /usr/local/cmcluster/bin /usr/local/cmcluster/doc/man For SLES: /opt/cmcluster/bin /opt/cmcluster/doc/man 2. Install the Metrocluster Add-ons B.01.00.00 rpm to install Metrocluster Add-ons for Linux. For Red Hat: # rpm –i serviceguard-metrocluster-addons-B.01.00.00.
For SLES: a. Extract the patch files from the SGLX_00451.tar file. b. Run the mc3parupdate script. You can find the mc3parupdate script under the tools directory. Metrocluster Limitations If the InForm OS version 3.1.2 is used, then the Metrocluster 3PAR Remote Copy for Linux does not support configuring the same WWID for the source side virtual volume and the target side virtual volume in a Remote Copy group.
• QXCR1001260884 When the Metrocluster 3PAR package fails over to different datacenter, the Metrocluster reverses the role of Remote Copy volume group and starts the volume group. The volume group fails to start when the volumes in the volume group are of large size. • QXCR1001267860 The cmapplyconf or cmcheckconf command fails when the name of the Remote Copy volume group specified in the Metrocluter 3PAR package configuration file is a substring of one of its Remote Copy virtual volume name.
