1 Metrocluster with EMC SRDF Version A.05.01 release notes Announcements Metrocluster with EMC SRDF (Metrocluster/SRDF) is a member of Hewlett-Packard’s family of high availability products for customers requiring integrated disaster recovery solutions. Metrocluster/SRDF integrates EMC SRDF/Synchronous and SRDF/Asynchronous with HP Serviceguard, allowing you to build clustering solutions to failover applications and data across geographically separated data centers.
New features in the patch PHSS_41308 on HP-UX 11i v1 Metrocluster/SRDF A.05.01 along with the patch PHSS_41308 provides support for the following new functionalities: • Support for Asynchronous Data Replication with SRDF Multi Session Consistency Feature Starting with this release, you can build a composite group for SRDF/Asynchronous Multi Session Consistency (MSC) data replication. However, you must configure these composite groups with devices that are SRDF/Asynchronous capable within the RDF groups.
Features introduced in Metrocluster/SRDF A.05.01 The A.05.01 version of Metrocluster/SRDF contains the following: • Support for HP-UX 11i v1 • Support for using SYMAPI • R1/R2 swapping recommendation • Fixes Metrocluster/SRDF contains the following files: The Metrocluster/SRDF environment template file for srdf.env defining the application environment. This template must be customized for specific EMC Symmetrix and host system configuration.
NOTE: Sample scripts use the node names ftsys1, 2, 1a, and 2a; change them to match your own cluster node names. Support for using SYMAPI Metrocluster/SRDF no longer depends on SYMCLI commands to retrieve status of and perform operations for Symmetrix devices. It now uses SYMAPI calls for communicating with Symmetrix devices. These SYMAPIs are installed when you install SYMCLI.
To use Metrocluster/SRDF, the following hardware and software must be installed and configured on each HP 9000 server or HP Integrity server that might execute the application package that has been configured for Metrocluster/SRDF. For more information on support, compatibility, and features for Metrocluster/SRDF, refer to the Disaster Tolerant Clusters Product Compatibility and Feature Matrix (Metrocluster/EMC SRDF-MC/SRDF) located at http://www.hp.com/go/hpux-serviceguard-docs.
— Symmetrix “5” ◦ 8130 ◦ 8230 ◦ 8430 ◦ 8530 ◦ 8730 ◦ 8830 — Symmetrix “6” (DMX Series) ◦ 800 ◦ 1000 ◦ 2000 ◦ 3000 — Symmetrix “7” (DMX Series) The two Symmetrix ICDAs connected by SRDF may be different models. DMX requires a minimum of Symmetrix “5” for an SRDF connection. • • • EMC Symmetrix DMX is required for SRDF/Asynchronous data replication. SRDF firmware must be configured, and hardware installed on both Symmetrix units. Symmetrix microcode level.
NOTE: To perform changes in the binary file, either contact EMC personnel or use Symmetrix Configuration Change CLI. • EMC Enginuity Level 5671 or higher is required for SRDF/Asynchronous support. NOTE: It is recommended that the microcode levels for all the Symmetrix systems be upgraded to the latest GA release version.
EMC Symmetrix Software Requirements for Metrocluster/SRDF A.05.01 HP-UX 11i v1 and HP-UX 11i v2: • EMC Solutions Enabler version 6.2, 6.2.1, 6.2.2 and 6.3 For more information on supported versions of Solutions Enabler, refer to the Disaster Tolerant Clusters Products Compatibility and Feature Matrix available at http:// www.hp.com/go/hpux-serviceguard-docs. • Single threaded SYMAPI run-time library. HP 9000 platforms, 32-bit single-threaded SYMAPI library must be installed.
5. 6. 7. 8. 9. For more details on how to upgrade Solutions Enabler, refer to the EMC Solutions Enabler Installation guide available on the EMC website. Once the firmware and the Solutions Enabler upgrades are completed, apply this patch on all the nodes of the Metrocluster. Existing Metrocluster environment files of the package can be used without any changes.
What Manuals are Available for this Version For information about configuring packages, refer to the following manual, which is shipped with Metrocluster/SRDF version number A.05.01.
Patches and Fixes in this Version The following patches need to be installed for Metrocluster/SRDF version A.05.01. However, this is subject to change without notice. For the most current information contact your HP support representative or Hewlett Packard IT Resource Center. Table 1-1 lists the required patches for Metrocluster/SRDF version A.05.01 on HP-UX 11i v2. Table 1-1 Required Patches Patch Number Description PHSS_35452 Metrocluster patch PHSS_35371 Serviceguard 11.
JAGaf05349 Problem: Metrocluster/SRDF package fails to startup on the R2 side if the background split is in progress when performing R1/R2 swap. Resolution: The problem is fixed in this version. The functionality of Metrocluster/SRDF has been enhanced to allow package startup to be enforced. A new value has been introduced for the environment variable AUTOSWAPR2. It can now be set to 2, to indicate that package needs to be automatically started in spite of R1/R2 swap failure.
