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

• 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 aheads 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.
• Fixes incorrect CFS token structure warnings.
• Prevents file inconsistency due to a race between lookup and remove.
• Provides a new cluster-specific link aggregation distribution algorithm when using LAG in
a LAN cluster.
• Fixes a simple lock timeout panic issue in kch and a possible hang at boot time
• Prevents an AIO DirectIO to return invalid data while reading a fragged file.
• Fixes a cluster hang issue during cluster boot-up, when local disk open operations fail while
disklabel is in progress.
• Fixes an error in the DRD subsystem wherein un-initialized disk attributes can cause a
system panic.
• Fixes KMF in rdg_get_completion() routine.
• Fixes a problem in which a cluster alias subsystem tries to free the mbuf that is already freed
by ICS subsystem.
• Corrects reference counting issues within the DRD subsystem that can prevent the deletion
of hwids.
• Adds a new option, custom_gated, to cluamgr and aliasd.
• Fixes a deadlock that can happen during failover of global root and var file systems when
vfast is enabled on them.
• Fixes resource leaks seen after a locked device file is revoked.
• Fixes system panics seen on relocating file systems with locked revoked devices.
