1 Serviceguard Extension for RAC Version A.11.20 Release Notes Announcements Effective September 2011, SGeRAC A.11.20 will be available bundled with HP-UX 11i v3 High Availability Operating Environment (HA-OE) and Data Center Operating Environment (DC-OE) September 2011 Update as an optional bundle media. Please note that performing a rolling upgrade from a Serviceguard only cluster with Serviceguard version A.11.19 and earlier version of OE to a Serviceguard and SGeRAC version A.11.
Dependencies and Limitations NOTE: For the most complete and up-to-date list of support and compatibility requirements, see the Serviceguard/SGeRAC/SMS/Serviceguard Manager Plug-in Compatibility and Feature Matrix. Serviceguard and related documentation is available free at www.hp.com/go/hpux-serviceguard-docs —> HP Serviceguard —> General reference. • See “Operating-System Dependencies” (page 7) and “Announcements for HP-UX 11i v3” (page 8). • Serviceguard version A.11.
• • Other Rolling upgrade restrictions: ◦ You can upgrade OS during rolling upgrade only if your cluster uses SLVM and ASM over Raw disks, or ASM over SLVM configuration for the shared storage. ◦ Refer to Oracle documentation if the rolling upgrade involves an Oracle RAC version upgrade. ◦ For more information, see the HP-UX 11i v3 version of the HP Serviceguard Storage Management Suite Release Notes at www.hp.
If you load optional SGeRAC A.11.20 bundle from the HA-OE or DC-OE September 2011 media, beginning with Serviceguard A.11.20 Patch PHSS_42137, Live Application Detach (LAD) will be supported in SGeRAC A.11.20 environment as long as Oracle CRS is not running on that cluster. After you deploy Oracle RAC, using the -d option with cmhaltcl (or cmhaltnode) command on a node in an SGeRAC cluster where CRS are running will return an error message and the cmhaltcl (or cmhaltnode) command is aborted.
Agile addressing is the default on new 11i v3 installations, but the I/O subsystem still recognizes pre-11i v3 device files, referred to as legacy device files. Device files using the new nomenclature are called persistent device files. When you upgrade to HP-UX 11i v3, a set of new, persistent device files is created. The existing legacy device files are left intact and by default will continue to be used by HP-UX and Serviceguard.
IMPORTANT: To enable cDSF functionality in Serviceguard A.11.20, a Patch (PHSS_41225 or later) is required. NOTE: cDSFs apply only to shared storage. They will not be generated for local storage, such as root, boot, and swap devices. HP recommends that you use cDSFs for the storage devices in the cluster because this makes it simpler to deploy and maintain a cluster, and removes a potential source of configuration errors. SGeRAC supports Cluster-wide Device Special File (cDSF) format. See below. 1.
• Patch PHSS_41642 for SGeRAC A.11.20 on HP-UX 11i v3 The patch supports the following new features: ◦ SGeRAC toolkit modular style Oracle Clusterware Multi-Node package (OC MNP) and Oracle RAC instance Multi-Node package (RAC MNP) can be configured through Serviceguard Manager with minimal user inputs. The OC MNP and RAC MNP package attributes will be discovered automatically. This requires Oracle Clusterware and RAC database to be up and running on all the cluster nodes.
• “GMS authorization” (page 16) • Support for DRD—see “Upgrade Using DRD” (page 16) • Support for multi-node online reconfiguration (MORE) of LVM volume groups—see “Support for Multi-Node Online Configuration (MORE)—LVM Version 2.1 Volume Groups Only” (page 14) • “Support for Logical Volume Manager Version 2.0 and later” (page 13) • “Support for Veritas CFS and CVM Versions 5.0.1 and 5.
the same cluster. HP recommends to upgrade all the cluster nodes to the new release level at the earliest. Support for the Oracle Grid Infrastructure 11.2.0.2 HAIP with SGeRAC A.11.20 Starting with SGeRAC A.11.19, Oracle Grid Infrastructure 11.2.0.2 HAIP feature can be configured and used in an SGeRAC cluster. The following network configuration requirements must be met to use the Oracle Grid Infrastructure 11.2.0.2 HAIP feature in an SGeRAC cluster: 1. Any networks in the SGeRAC A.11.
Support for Multi-Node Online Configuration (MORE)—LVM Version 2.1 Volume Groups Only Multi Node Online Reconfiguration (MORE), introduced in the HP-UX 11i v3 September 2009 release, allows you to change the configuration of LVM Version 2.1 volume groups while the volume groups are activated in shared mode on any number of cluster nodes. Applications can continue to use these volume groups without interruption while the volume groups are being reconfigured.
NOTE: For instructions on adding or deleting a Serviceguard node when Oracle RAC and the HP Storage Management Suite are configured, see the HP-UX 11i v3 version of the HP Serviceguard Storage Management Suite Version Release Notes at www.hp.com/go/hpux-serviceguard-docs —> HP Serviceguard Storage Management Suite —> Getting started. Support for Oracle 10gR2 RAC with SLVM and ASM SGeRAC on HP-UX 11i v3 with Serviceguard A.11.20 supports Oracle 10gR2 RAC with SLVM, ASM over SLVM or raw disks/LUNs.
Support for toolkit maintenance mode This feature allows you to perform Oracle OC/ASMDG/RAC maintenance while OC/ASMDG/RAC multi-node packages are running in the cluster. It is implemented in the SGeRAC Toolkit by means of the MAINTENANCE_FLAG parameter. See the white paper Use of Serviceguard Extension for RAC Toolkit with Oracle RAC 10g Release 2 or later, at the address given above, and the SGeRAC Toolkit README.
If, after reading and understanding the restrictions, you decide to perform a rolling upgrade using DRD, follow the instructions under “Performing a Rolling Upgrade Using DRD” (page 20). Non-Rolling Upgrade Using DRD In a non-rolling upgrade with DRD, you clone each node's root disk and apply the upgrade to the clone, halt the cluster, and then reboot each node from its updated clone root disk.

Compatibility Information and Installation Read this entire document and any other Release Notes or READMEs you may have before you begin an installation.
Ensure that the entries are numbered in proper order. For example, if there are three entries already present for TCP or UDP ports in nddconf, then they are numbered 0 through 3: TRANSPORT_NAME[0]=tcp, TRANSPORT_NAME[1]=tcp, and TRANSPORT_NAME[2]=tcp. The entries you add are then TRANSPORT_NAME[3]=tcp and TRANSPORT_NAME[4]=tcp. TRANSPORT_NAME[5]=udp and TRANSPORT_NAME[6]=udp.
Performing a Rolling Upgrade Using DRD CAUTION: See the limitations listed in Appendix A of Using Serviceguard Extension for RAC. In addition, there are special conditions that apply to upgrading a system to Serviceguard A.11.20. You should read the entire section on “Rolling Software Upgrades” in Appendix A of Using Serviceguard Extension for RAC, and the HP Serviceguard Version A.11.20 Release Notes. Limitations of Rolling Upgrades using DRD CAUTION: Stricter limitations apply to an upgrade to A.11.20.
6. 7. 8. Halt the node. You can do this in Serviceguard Manager, or use the cmhaltnode (1m) command. This will cause the node’s packages to start up on an adoptive node. Reboot the node from the updated clone root disk. Edit the /etc/rc.config.d/cmcluster file to include the following line: AUTOSTART_CMCLD = 1 9. 10. 11. 12. Restart the cluster on the upgraded node, using Serviceguard Manager or cmrunnode (1m). Restart Oracle (RAC, Clusterware) on the upgraded node.
Steps for a Non-Rolling Upgrade Using DRD Use the following steps for a non-rolling software upgrade using DRD: 1. Create a clone root disk for each node. 2. Upgrade each clone disk to the new HP-UX release (if necessary), including Serviceguard (using drd runcmd update-ux), or upgrade Serviceguard alone (using drd runcmd swinstall). 3. Upgrade each clone disk to the new release of SGeRAC. 4. Halt Oracle (RAC, Clusterware) on all nodes in the cluster. 5. Halt all nodes in the cluster: cmhaltcl -f 6. 7.
Removing Serviceguard Extension for RAC without Removing Serviceguard If you want to remove SGeRAC and return the cluster to use as a Serviceguard cluster, use the following steps: 1. Take a back-up of cluster configuration using cmgetconf –c command. 2. Take a back-up of package configurations using cmgetconf –p command for all the packages that you want to retain in the target Serviceguard cluster. 3. Halt the cluster using cmhaltcl –f command. 4.
