HP Serviceguard Version A.11.19 Release Notes, March 2009

Root Access to an Unconfigured Node” in Chapter 5 of Managing Serviceguard for more
information.
cmviewconf Deprecated
cmviewconf is deprecated as of Serviceguard A.11.19; this command will be obsolete
in a future release. Use cmviewcl 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 11) make the
Serviceguard Extension for Faster Failover (SGeFF) obsolete. If SGeFF is present, it will
be removed from the system when you install Serviceguard A.11.19.
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 configuration of Serviceguard on HP-UX 11i v2 or 11i v3 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.11.19 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
