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

• Eliminates a performance problem when a node acting as CFS server of an NFS
client file system is write-appending to an external NFS server.
• Prevents a panic when an AutoFS file system is auto-unmounted.
• Corrects the cause of a cluster member panic with kernel memory fault when
running nmap or nessus targeting at the cluster alias.
• Resolves a problem in which the caa_register command allows a CAA resource
to be registered even when its profile contains an unknown attribute. This fix
prevents the caa_register command from registering a resource with an unknown
attribute and will cause it to return an error message that includes the unknown
attribute information.
• Fixes a condition in which uptimes greater than 100 percent are reported for
resources by caa_report.
• Fixes a problem in which resources that never started have an ending timestamp.
• Fixes a problem in which CAA dumps core when trying to deal with cluster
member ID 63.
• Fixes an problem where access to the quorum disk can be lost if the quorum disk
is on a parallel SCSI bus and multiple bus resets are encountered.
• Relieves pressure on the CMS global DLM lock by allowing AutoFS auto unmounts
to back off.
• Fixes cfsmgr to properly return a failure status when a relocation request has failed.
• Fixes a race condition where stale name cache entries allow file access after file
unlink.
• Corrects a problem in which cfsd will terminate prematurely and core dump when
a node leaves the cluster very shortly after joining the cluster.
• Fixes a timing window during asynchronous reads on a CFS client.
• Fixes a panic that may occur during an unmount.
• Corrects several problems with various installation commands and utilities.
• Fixes a memory leak in the clu_get_info interface.
• Enhances cluster file system performance when using file locks to coordinate file
access.
• Causes the correct error message for freezefs -q to be displayed on a non-AdvFS
file system.
• Fixes a problem in one of the shipped rc scripts whereby Oracle fails during startup
on a clustered system.
• Addresses a panic that occurs on a booting node.
• Fixes a coding error, a memory leak, and a deinitialization problem in the cluster
interconnect networking layer.
• Fixes a problem in the Device Request Dispatcher.
• Provides clu_upgrade enhancements.
