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

• 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.
