Serviceguard Version A.11.17 on HP-UX 11i v3 Release Notes 1 Chapter 1 Serviceguard Version A.11.
Serviceguard Version A.11.17 on HP-UX 11i v3 Release Notes Announcements Announcements Serviceguard allows you to create and manage high availability clusters. This new version of Serviceguard is officially known as Serviceguard A.11.17 on HP-UX 11i v3, but is sometimes also referred to as Serviceguard A.11.17.01. Serviceguard Bundled Components - New Product Structure The following Serviceguard components are now available for HP-UX 11i v3: • Product T1905CA —A.11.
Serviceguard Version A.11.17 on HP-UX 11i v3 Release Notes Announcements Advantage of the New Product Structure This new product structure for the first time allows Serviceguard customers who subscribe to Update services to download Serviceguard from the web (along with the three sub-products classed as Serviceguard components and listed above) via Software Update Manager (SUM).
Serviceguard Version A.11.17 on HP-UX 11i v3 Release Notes Announcements • two heartbeat subnets; or • one heartbeat subnet with a standby To provide the required redundancy for both networking and mass storage connectivity on servers with fewer than three I/O slots, you may need to use multifunction I/O cards that contain both networking and mass storage ports. Veritas CVM and CFS Not Yet Supported Serviceguard A.11.
Serviceguard Version A.11.17 on HP-UX 11i v3 Release Notes Announcements When you upgrade a system to HP-UX 11i v3, the I/O subsystem by default will start performing load balancing and multipathing for all multipath devices (whether or not they are managed by VxVM/DMP, and whether or not you decide to migrate the system to agile addressing); you do not have to take any additional steps to make this happen.
Serviceguard Version A.11.17 on HP-UX 11i v3 Release Notes Announcements Online Replacement of LAN Cards Requires Patch Before you can replace a LAN card online (without bringing down the cluster) as described under “Replacing LAN or Fibre Channel Cards” in chapter 8 of Managing Serviceguard, you must apply patch PHNE_35894. See “Patches and Fixes in this Version” on page 46 and “JAGag27186 (SR8606472298): OLR of a LAN Card in SG cluster fails” on page 55.
Serviceguard Version A.11.17 on HP-UX 11i v3 Release Notes Announcements High Availability Consulting Services Because Serviceguard configurations can be complex to configure and maintain, HP strongly recommends that you use its high availability consulting services to ensure a smooth installation and rollout; contact your HP representative for more information.
Serviceguard Version A.11.17 on HP-UX 11i v3 Release Notes What’s in this Release What’s in this Release This release of Serviceguard A.11.17 (also known as A.11.17.01) supports HP-UX 11i v3 and adds new functionality, specifically: • Serviceguard supports HP-UX agile addressing, sometimes also called persistent LUN binding, for device special files (DSFs). See “About Device Special Files (DSFs)” on page 13. • Serviceguard supports HP-UX native multipathing and load balancing.
Serviceguard Version A.11.17 on HP-UX 11i v3 Release Notes What’s in this Release — Serviceguard now supports Virtual LANs (VLANs) over APA. (VLANs over physical interfaces were already supported.) For more information, see the sections “Automatic Port Aggregation” and “Configuring VLANs” in chapter 3 of the latest edition of Managing Serviceguard in the High Availability collection on docs.hp.com. • Hostnames for Serviceguard cluster nodes can be up to 39 characters (bytes) long.
Serviceguard Version A.11.17 on HP-UX 11i v3 Release Notes What’s in this Release Under the agile addressing convention, the hardware path name is no longer encoded in a storage device’s name; instead, each device file name reflects a unique instance number, for example /dev/[r]disk/disk3, that does not need to change when the hardware path does. Agile addressing is the default on new 11i v3 installations, but the I/O subsystem still recognizes pre-11.
Serviceguard Version A.11.17 on HP-UX 11i v3 Release Notes What’s in this Release scheme without bringing the cluster down. For the requirements and a procedure, see “Updating the Cluster Lock Configuration” in chapter 7 of Managing Serviceguard. For more information about agile addressing, see following documents at http://www.docs.hp.com.
Serviceguard Version A.11.17 on HP-UX 11i v3 Release Notes What’s in this Release NOTE If you are replacing, rather than removing, the interface, and you have applied patch PHNE_35894,you do not need to bring down the cluster, and you may be able to do the replacement online; see “Replacing LAN or Fibre Channel Cards” in chapter 8 of Managing Serviceguard.
