Serviceguard Version A.11.16 Release Notes, 2nd Edition, September 2004

Serviceguard Version A.11.16 Release Notes, Second Edition
Patches and Fixes in this Version
Chapter 142
The cmcheckconf and cmapplyconf have been enhanced to not
allow verification of a cluster if at least one of the netmasks in the
cluster has been changed in the system. This is to prevent users from
changing their network masks, which is an unsupported
configuration change, after the cluster has been up and running.
JAGae91402 Cmscancl ’network connection checking’ is wrong
• What was the problem? The PPA values of the HyperFabric interfaces
are the same as ethernet network interfaces thus causing the
linkloop command used in cmscancl to give incorrect results.
Clic0(HyperFabric interface) has PPA 0, same as lan0 (Ethernet
interface). Linkloop uses the card PPA number, and so can’t really
distinguish between cards.
• What was the resolution? Skip the network connectivity check for
non-LAN hardware (i.e. HyperFabric, ATM etc.), if any, since linkloop
command is supported only for LAN hardware.
JAGae91372 WARNING statements from config cmds cause
undue concern
• What was the problem? Serviceguard configuration commands
(cmquerycl, cmcheckconf, cmapplyconf and cmgetconf) all generate
the following sort of messages when they detect a disk which does
not belong to an LVM volume group or a VxVM disk group:
Warning: Disks which do not have IDs cannot be included
in the topology description. Use pvcreate(1M) to
initialize a disk for LVM or, use vxdiskadm(1M) to
initialize a disk for VxVM.
and
Warning: The disk at /dev/dsk/c1t2d0 on node eon does not
have an ID, or a disk label.
• What was the resolution? (1) Removed the frequent message: Unable
to determine a unique identifier for physical volume %s
on node %s. Use pvcreate to give the disk an identifier.
(2) Reworded this one-time message:
