• Fixes a problem of v_numoutput not decremented for aio dio error paths.
• Removes the cause of a panic that may occur in CFS at boot time if a remote node
goes down.
• Corrects several ICS signal-forwarding issues.
• Fixes a race between the close system call for a block device file and the recovery
process for the file system.
• Clarifies a usage message seen with the cfsstat command.
• Corrects a problem in clu_mibs daemon that can cause various eSNMP sub agents,
such as pmgrd and os_mibs, to terminate.
• Fixes a problem to prevent the relocation of UFS read/write file system to the
original node.
• Provides new option to the mountd daemon to specify a port number for mountd
to bind to.
• Corrects a problem in which a DRD event thread may run infinitely while

• Provides enhancements to the caa_relocate command.
• Provides a new command, clu_ping, to determine the status of the interconnects

• Improves CFS client writing to do the following:
— reduce the logging of ERROR 69 for user disk space quota exhausted.
— support partial write success.
— increase the interconnect transfer size for multi-page synchronous writes.
— prevent read ahead past the end of a file.
• Helps ensure more accurate block reservation accounting in CFS.
• Addresses an issue seen on Tru64 UNIX LAN clusters, whereby a booting node
may panic with "lock_wait" while spawning threads for cluster interconnect
channels.
• Provides a solution to display a warning message if deleting a particular cluster
member would cease NTP services for the rest of the cluster.
• Improves the routing fail-over mechanism when one or more network interfaces
on any cluster member fails.
• Fixes a "kernel memory fault" panic in cfs_fo_failover_done().
• Fixes a problem wherein the DRD subsystem may cause a system panic when
