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

• Fixes a klog inconsistency during node boot in which it is possible that no nodes in the
cluster respond to a klog sync request and the booting node simply clears the disk group
klog.
• Decreases CLSM boot times in large cluster configurations.
• Fixes problems in the vol_new_disk ioctl when errors are encountered when loading a disk
in the kernel.
• Fixes the cause of a panic in LSM voldrl_commit_delete that occurs during a transaction
abort.
• Corrects the cause of a panic in LSM voldrl_commit_delete seen during a transaction abort.
• Adds performance enhancements to help reduce LSM cluster-wide plex-detach processing
time.
• Fixes a problem whereby LSM does not properly removing plex detach entries from its
kernel change log in a TruCluster environment.
• Fixes an issue with kernel plex detach by attempting to further reduce the number of
redundant detach events sent from the kernel to vold.
• Fixes a boot problem with the LSM I/O performance change when the root file system is an
LSM volume.
• Adds a configurable fastfail option to the LSM driver for mirrored volume I/O.
• Modifies conditions to allow multiple retries to mount the root file system and provide the
ability to adjust the retry period.
• Corrects a locking issue in KCL local lock.
• Fixes an "assert wait" panic caused by automatic LSM error tracing when DRD uses LWC
(light weight context) switching and many I/O and plex detaches occur.
• Fixes a problem in which I/O requests hang when multiple LSM kernel-initiated plex detaches
are processed simultaneously by different cluster members across different diskgroups.
Patch 27052.00
OSFLSMX11540
• Prevents a process hang occurring when large I/O's are performed on multiple drl-enabled
LSM volumes simultaneously on Multi-CPU systems.
• Causes zero length I/O requests to be flagged with the proper error message to the user
rather than causing a panic.
• Fixes a “clsm_config" dlm_lock deadlock issue.
Patch 27053.00
OSFLSMX11540
• Fixes a problem in the LSMSA GUI where the application throws a Null Pointer Exception
while trying to display volume and fileset information on systems having ASU file-on-file
mounts.
Patch 27054.00
OSFMANOP540
• Updates the uucp(1), gethostbyaddr(3), getnameinfo(3), sys_attrs_io(5), kdbx(8), named(8),
and volwatch(1) reference pages.
• Updates the dd(1), ksh(1), vi(1), aio_return(3), sshd2_config(4), emx(7), dxshutdown(8),
newfs(8), prpasswdd(8), sshd2(8), and ypset(8) reference pages.
• Revises the EvmEventPost(3) reference page to document the return value

• Revises the nsdispatch(3) reference page.
• Revises the getaddrinfo(3) reference page to document the POSIX_SOURCE compiler flag.
