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

• Removes a delay in the TruCluster component DRD (Device Request Dispatcher)
event threads during system booting.
• Corrects a kernel memory fault in drd_local_device_close.
• Fixes a kernel memory fault issue on LAN-based clusters that do not have a
Memory Channel adapter installed on the systems.
• Fixes problem of non-root users not being able to execute the caa_stat command.
• Provides enhancements to CAA commands and the caad daemon.
• 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.
• Allows 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 inaccessible 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.
