HP Serviceguard Version A.11.20 Release Notes, August 2011

ipnodes Entries Needed in /etc/nsswitch.conf
Beginning with version A.11.19, Serviceguard uses calls that require ipnodes entries to be
configured in the /etc/nsswitch.conf. See “Safeguarding against Loss of Name Resolution
Services” in Chapter 5 of Managing Serviceguard for more information.
Legacy Packages
As of Serviceguard A.11.20, new package features are being implemented only in modular
packages (those created using the method introduced in A.11.18).
IMPORTANT: Support for legacy packages (created using the earlier method) will be withdrawn
altogether in a future release. Use the modular method to create new packages whenever possible.
See Chapter 6 of Managing Serviceguard for more information.
STORAGE_GROUP Deprecated
The STORAGE_GROUP parameter (in the package configuration file for legacy packages) is
deprecated as of Serviceguard A.11.19. Support for it will be withdrawn in a future release.
A package using Veritas Cluster Volume manager from Symantec (CVM) disk groups for raw
access (without Veritas Cluster File System from Symantec, or CFS) needs to declare a dependency
on SG-CFS-pkg; see “Creating the Storage Infrastructure with Veritas Cluster Volume Manager
(CVM)” in Chapter 5 of Managing Serviceguard for more information.
Do Not Use .rhosts
Do not use .rhosts file as a means of allowing root access to an unconfigured node. Use
$SGCONF/cmclnodelist instead. See “Allowing Root Access to an Unconfigured Node” in
Chapter 5 of Managing Serviceguard for more information.
cmviewconf Obsolete
cmviewconf is obsolete as of Serviceguard A.11.20. Use cmviewcl (1m) to obtain information
about the cluster. See “Reviewing Cluster and Package Status” in Chapter 7 of Managing
Serviceguard for more information.
Serviceguard Extension for Faster Failover Obsolete
Performance improvements in the New Cluster Manager (page 8) make the Serviceguard Extension
for Faster Failover (SGeFF) obsolete. If SGeFF is present, it will be removed from the system when
you upgrade to Serviceguard A.11.19 (preparatory to a rolling upgrade to A.11.20) or A.11.20.
RS232 Heartbeat Obsolete
The current version of Serviceguard does not support RS232 for the cluster heartbeat (Serviceguard
A.11.17 on HP-UX 11i v2 and A.11.16 on HP-UX 11i v1 were the last versions that did).
A minimum Serviceguard configuration needs 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; or
• one heartbeat subnet using APA with two physical ports in hot standby mode or LAN monitor
mode.
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.
