HP Serviceguard Version A.11.17 Release Notes, March 2006 (revised)

Serviceguard Version A.11.17 Release Notes
Announcements
Chapter 1 7
Current and earlier versions of Serviceguard on HP-UX support using a
serial line (RS232) as an alternate heartbeat in some configurations, but
future Serviceguard and HP-UX releases will not: Serviceguard A.11.17
on HP-UX 11i v2 and A.11.16 on HP-UX 11i v1 are the last versions that
will support RS232 for heartbeat messaging. Instead, a minimum
configuration will need two network interface cards for the heartbeat in
all cases, using one of the following configurations:
• 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.
Since Serviceguard configurations may be complex to configure and
maintain, it is strongly recommended that you use Hewlett-Packard’s
high availability consulting services to ensure a smooth installation and
rollout. Please contact your HP representative to inquire about high
availability consulting. In addition, you should work with your HP
representative to ensure that you have the latest firmware revisions for
disk drives, disk controllers, LAN controllers, and other hardware.
Release Notes Revisions
Occasionally important new information becomes available that
warrants revising the Release Notes after they have gone to press. In
such cases HP updates the Release Notes on docs.hp.com
(http://www.docs.hp.com ->High Availability->Serviceguard->Release
Notes). If you find a discrepancy between a printed (or CD) version of the
Release Notes and the Release Notes on docs.hp.com, and the part
numbers are the same, you can assume that the docs.hp.com version is
more up-to-date.
