HP Tru64 UNIX and TruCluster Server Version 5.1B-6 Patch Summary and Release Notes

• Corrects a problem in which the simultaneous booting of multiple nodes results in a panic
due to an unknown node in a remote member node list.
• Corrects a problem in a Memory Channel cluster in which a panic occurs in a booted member
when a booting member goes down because of panic/halt/shutdown.
• Fixes a problem in which a thread enters dio code while an extent map is being refreshed.
• 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 responding for
bid server transaction.
• Fixes and AdvFS domain panic caused by cfsd.
• Corrects a problem in CAA in which a resource does not fail over when two resources have
the same values for the FAILOVER_DELAY and REQUIRED_RESOURCES attributes.
• Fixes a hang during cluster bootup caused by early reservation conflicts.
• Provides enhancements to the caa_relocate command.
• Provides a new command, clu_ping, to determine the status of the interconnects in a stretched
cluster environment.
• 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 strategy
routines are called from a light weight context (LWC).
• Fixes display errors in the cfsstat command when using the icschanbps option.
• Fixes display errors in cfsstat command when using the icschanbps option.
• Fixes a deadlock issue between cluster nodes because of cfs_async_io_thread running on
them.
• Corrects an erroneous error message displayed by drdmgr.
• Fixes a cnx_qdisk_thread hang problem.
• Fixes a memory leak in CFS.
• Fixes disk I/O hang in DRD.
• Fixes a hang with disklabel that occurs if a local open fails for the same disk simultaneously.
