HP-UX 11i Version 2 Release Notes (October 2003)

General System Administration

MC/ServiceGuard

Chapter 4

— ServiceGuard supports only one IPv6 address belonging to each scope type

(site-local and global) on each network interface (that is, restricted

multi-netting). Therefore, up to a maximum of two IPv6 STATIONARY_IPs can be

mentioned in the cluster ascii file for a NETWORK_INTERFACE: one being the

site-local IPv6, and the other being the global IPv6.

— Quorum Server, if used, has to be configured on an IPv4 network. It is not

IPv6-capable. A Quorum Server configured on an IPv4 network can still be used

by ServiceGuard IPv6 clusters that have IPv6 networks as a part of their cluster

configuration.

— ServiceGuard supports IPv6 only on the Ethernet networks, including 10BT,

100BT, and Gigabit Ethernet.

The following are not supported on SG A.11.15.00:

• Advanced Tape Services

• ServiceGuard SAM interface is not included

•Partitioned Luns

• Virtual Partitions (vPARs)

• Mixed Itanium-based and PA-RISC nodes within a cluster

• Auto Port Aggregation (APA)

• Virtual LAN (Vlan)

• HP-UX 11i v1.6

• The rx9610 and rx4610 servers

• U2 SCSI cards and combo cards

• Boot support with Tachlite

Impact

If you want to use the new features of SGeRAC A.11.15.00, then you may need to edit the

existing ASCII configuration files and control scripts, and you must reapply them to the

cluster.

Rolling upgrade will be provided from MC/ServiceGuard A.11.14.01 (Itanium-based) to
