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

• 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.
• Increases performance by reducing the lock miss rate in the ics_mct_llnode_info_lock.
• Addresses the panic “Assert Failed: (cp-c_flags & CDIRECTIO) = 0” in the cluster file system.
• Corrects a problem where a CFS lookup for a mount could leave stale state behind that could
adversely affect subsequent NFS operations.
• Fixes an internal problem in the kernel's AdvFS, UFS, and NFS file systems where extended
attributes with extremely long names, greater than 247 characters, could not be set on files.
The new limit is 254 + a null string terminator.
• Corrects problems with LSM disks and the cluster quorum tools. When a member having
LSM disks local to it is down, the quorum tools fail to update quorum. This causes other
cluster commands to fail.
• Corrects a problem in which mounting on a directory in a clone fileset fails with the message
"Device Busy."
• Prevents a Kernel Memory Fault Panic in some cases where AdvFS administration commands
are performed on a mounted fileset of an inaccessible AdvFS domain.
• Fixes a problem in which CAAD might dump core due to a race condition when multiple
events to which it subscribes arrive simultaneously.
• Improves the fragment gathering mechanism to boost performance.
• Fixes panic problem when attempting to unload clua.mod.
• Fixes a condition that causes a boot up panic when ippport_userreserved is 1000 or less.
• Fixes a cfsmgr core dump when passing the incorrect number of arguments upon force
unmounting a served file system.
• Fixes a problem in which a CFS client for a file with a hole preceding a frag might drop the
frag.
• Optimizes cluster file system lock recovery, potentially speeding up the time required to
failover a file system to a new server.
• Corrects a condition in which superfluous "rm_event, index too big" messages may appear
on system consoles.
• Addresses a panic that may occur when a node is joining the cluster. A node recognizing
the joining node panics while it is trying to establish a preboot channel connection with the
peer node, causing the following message to be displayed on the console or in
/var/adm/messages:
panic (cpu x): ics_mct: rx conn 3
• Corrects the LSM partition types in the CNX partition of boot disk for the clu_partmgr utility.
• Modifies the aliasd daemon to include interface aliases when determining whether or not
an interface is appropriate for use as the ARP address for a cluster alias when selecting the
proxy ARP master.
• Fixes the potential of multiple assert_wait and timeout panics due to kernel EVM threads
not properly preempting.
• Fixes a problem in the Memory Channel driver.
• Corrects a condition that occurs during a rolling upgrade in which the clu_ifaccess script
removes the tag file for /etc/ifaccess and sends out a warning message.
• Forces a reboot to resolve communications problems in a two node cluster rather than hang.
