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

• Provides enhancements for NetRAIN operation.
• Adds the ability to decouple RPC client retransmission activity from the UDP or
interface transmission completion handling.
• Fixes a logic error in the virtual memory macros used for accessing the memory
descriptor.
• Allows multiple retries to mount the root file system and the ability to adjust the
retry period.
• Fixes a problem in which the operating system receives an environmental machine
check packet from the firmware but fails to correctly recognize the sensor that is
identified as faulty by the machine check.
• Fixes a problem that prevents keyboard input during interactive booting (SRM
boot flag "i") when in graphics mode on GS1280/ES80/ES47 AlphaServers.
• Enhances the fuser command to provide a cluster-wide query capability. A revised
fuser(8) reference page describes this enhancement.
• Fixes mass storage disk subsystem handling of specific important events reported
by the HSG80 and HSG60 array controllers.
• Provides improvements to the TCP Selective Acknowledgment (SACK) option.
• Provides a workaround for the firmware limitation on SAS kernel size.
• Raises the highest ID handled by edquota and repquota and converts the repquota
program to using the GETQUOTA/GETQUOTA64 quotactl's for obtaining data,
instead of directly reading from the quota file. This results in more recent data
and, in a cluster, consistent data across all nodes. It also enables handling the
highest UIDs (up to 4294967294).
• Fixes a problem that corrects the status message which is output during boot
operations before the binary.errlog log file is available.
• Fixes a memory troller panic during a boot in low-memory conditions.
• Fixes a rare kernel memory fault that can occur when booting an AlphaServer
ES80.
• Changes I/O retry processing when a command time out is encountered by causing
the retry code to attempt to take advantage of other active paths during retries if
command time outs are encountered.
