HP Tru64 UNIX and TruCluster Server Version 5.1.B-4 Patch Summary and Release Notes (13156)

• Resolves a resource exhaustion problem in the TruCluster kgs/kch subsystem on high-end
clusters, typically with large storage configurations.
• Fixes an assert failure in cfs the server.
• Resolves a problem that occurs when adjusting sysconfig clua attributes sticky_entry_timeout
and sticky_db_cleanup_interval.
• Ensures that if only a portion of an AIO/DIO write completes, the correct number of bytes
written will be returned.
• Alows CFS to correctly handle a token race condition without creating a panic.
• Prevents a node in a cluster from hanging at boot time.
• Corrects misspellings of file system in the cfsmgr utility.
• Implements the fast fail policy within DRD.
• Corrects a problem in which backplane RAID devices can become inaccessible when installed
on systems running Version 5.1B-2 (Patch Kit 4).
• Enhances the fuser command to provide cluster-wide query capability.
• Ensures that the number of icsmct receive threads does not exceed the number of CPUs.
• Corrects a condition in which drd_get_disk_attributes hang if too many errors are
encountered, causing new devices to be inaccesible in a cluster from some cluster members.
• Corrects a problem in which a cluster CFS client would panic in cfscall_writepages, reporting
ASSERT (error != EDQUOT) . This correction eliminates that failure and allows for the proper
writing up to the fileset quota and to the end of space for a domain.
• Fixes a rare, three-way deadlock condition when Internode Communication Services (ICS)
traffic is in a throttled state and a cluster member that is participating in the throttled traffic
is halted.
• Fixes a kernel memory fault in strlen on a cluster member during a mount of an AdvFS files
ystem with an improperly specified file system.
• Allows the ulimit -f command to function correctly in a cluster.
• Prevents a kernel memory fault panic that may occur with client writes on nearly full
domains.
• Prevents a panic on a device close when device connectivity is lost.
• Fixes a mounting KMF of partitioning file system in a cluster.
• Fixes a problem in which a CAA resource and its dependents become inaccessible when the
resource fails to start on the node where it is failed over to and there are no more nodes to
consider for failover.
• Fixes Oracle socket connection problem.
• Fixes incorrect error handling that could result in memory leak.
• Provides event definitions for traps in cluster MIB files to support Openview NMS.
• Modifies ics_tcp to check response buffer for NULL before freeing it.
• Fixex a problem in which booting times in excess of 2 hours occur in a two-node LAN cluster
using an ee (DE6xx) adapter as the cluster interconnect and connected directly by a crossover
cable.
• Corrects a scenario during a cluster member boot whereby a booting member may cause
booted members to panic on a kernel memory fault shortly after the messages "Registering
CMS Services" and the "rm slave" are printed to the booting console for each MC card.
• Fixes a problem that could cause the system panic "clua_realloc_port: corrupt list pointers
panic".
• Corrects trapOID for traps generated from the clu_mibs subagent and provides event
definitions for traps in MIB files to support Openview.
• Fixes an inappropriate message that is displayed during CAA resource relocation when
invoked from SysMan.
• Fixes 64-byte memory leak in the drd/kgs interface.
