HP Serviceguard A.11.20 Release Notes, September 2012

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 Support for it will be withdrawn in a future release.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cmviewconf is obsolete as of Serviceguard A.11.20.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.
Token Ring and FDDI Obsolete
Serviceguard A.11.20 does not support Token Ring and FDDI technologies for the cluster heartbeat
and data networks (Serviceguard A.11.17 on HP-UX 11i v2 and A.11.16 on HP-UX 11i v1 were
the last versions that did). HP-UX 11i v3 does not support these two technologies.
The unsupported configurations include physical Token Ring and FDDI interfaces, Virtual LAN
(VLAN) interfaces over FDDI or Token Ring, and failover groups of Token Ring and FDDI interfaces
in the LAN Monitor Mode of the APA product.
Parallel SCSI Dual Cluster Lock Obsolete
You must use Fibre Channel connections for a dual cluster lock; you can no longer implement it in
a parallel SCSI configuration (as of Serviceguard A.11.18). See “Dual Lock Disk” in Chapter 3
of Managing Serviceguard for more information about dual cluster locks.
