HP Serviceguard Version A.11.17 on HP-UX 11i v3 Release Notes, February 2007

Serviceguard Version A.11.17 on HP-UX 11i v3 Release Notes
What’s in this Release
Chapter 1 13
— 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. (The former limit was 31 characters.)
• Serviceguard supports Process IDs (PIDs) of any size, up to the
maximum value supported by HP-UX and the node’s underlying
hardware architecture.
Previous versions of HP-UX imposed a limit of 30,000; this limit has
been removed as of HP-UX 11i v3. For more information, see the
white paper Number of Processes and Process ID Values on HP-UX
on docs.hp.com.
For more information about this release, see the subsections that follow,
and “Announcements” on page 6. For information about documentation,
see “What Documents are Available for This Version” on page 31.
What’s Not in this Release
• RS232 is no longer supported for the cluster heartbeat.
• Cluster Volume Manager (CVM) and Cluster File System (CFS) from
Symantec are not yet supported with Serviceguard A.11.17 on
HP-UX 11i v3.
Version 4.1 of Veritas Volume Manager (VxVM) from Symantec is
supported on HP-UX 11i v3, but VxVM 3.5 is not.
See “Announcements” on page 6 and “Rolling Upgrade Exceptions” on
page 44 for more information.
About Device Special Files (DSFs)
HP-UX releases up to and including 11i v2 use a naming convention for
device files that encodes their hardware path. For example, a device file
named /dev/dsk/c3t15d0 would indicate SCSI controller instance 3,
SCSI target 15, and SCSI LUN 0. HP-UX 11i v3 introduces a new
nomenclature for device files, known as agile addressing (sometimes
also called persistent LUN binding).
