HP Tru64 UNIX and TruCluster Server Version 5.1B-5 Patch Summary and Release Notes (March 2009)

• Fixes the long delay during an NFS connection failover when servicing cluster
member dies.
• Fixes a panic in clua.mod that is caused by receiving a delete-cnx-request from a
member when that cnx is in the UNREGISTER state.
• Fixes a reconnection problem when an interface comes down and then goes up.
• Fixes a panic problem in clua.mod that occurs when max_aliasid is increased and
aliases are added.
• Fixes a situation that causes a core dump in aliasd when all interfaces are removed
on a cluster member that is set up with at least one cluster alias that was added
with virtual=t and without a subnet.
• Fixes a problem when disabling and re-enabling cluster alias source route on a
given interface.
• Fixes a problem where clua.mod does not handle TCP RST messages appropriately.
• Fixes a problem of restoring static routes when an interface revives.
• Corrects a problem in which a rolling upgrade stops advancing when adding a
cluster member to a one-node cluster.
• Fixes an initialization issue with the internode communications subsystem.
• Corrects a problem in which a domain panic on the cluster_root does not result
as it should in a regular panic for the cluster node on which the domain panic
occurs.
• Fixes several small issues with clu_upgrade:
— A "process not found" message displayed when finishing the setup stage of
clu_upgrade has been removed.
— The ability to roll on a one-node cluster is maintained.
• Addresses a problem on LAN clusters related to improper keep-alive timeouts
that can be identified when the following console message is displayed during
normal operations (that is, no know failures and no nodes are rebooting):
— WARNING: ics_socket_event: error 60 on channel 0, assume node # is down
• Fixes a problem that occurs when the interconnect is configured using NetRAIN,
cluster_rebuild_delay is set significantly below the default value, and members
are rebooting or failures are occurring on the active links. The console message
seen when this occurs is “CNX QDISK: Yielding to foreign owner with provisional
quorum.”
• Fixes a problem in which I/O barriers may be stalled when a drive becomes hung.
• Prevents write failures from a cluster NFS client that may occur when a second
user without write access is concurrently reading the file.
• Fixes a problem that occurs during reboots on heavily loaded cluster using the
LAN interconnect and generates the following messages:
— WARNING: ics_socket_event: error 54 on channel 0
— WARNING: ics_socket_event: error 60 on channel 0
