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

• Corrects a condition that causes bootstrap address collisions after console
heap_expand uses more memory and extends into address range used by the
kernel.
• Updates the tu driver to support Ethernet Multicast addresses larger than 512,
which is necessary to support a large number of IPv6 addresses
• Updates the alt driver to V2.0.20 to fix issues with IPv6, NFS performance and
SNMP
• Fixes an improper handling of domain, area, and fabric RSCNs, or Registered State
Change Notifications by the emx driver that results in the nondetection of path
failures to storage devices in the fabric.
• Fixes and improves the mcutil program by correcting how bus resets are handled
by the program and enhancing its error reporting capabilities.
• Fixes a problem where Ultrium 2 tape drives do not use hardware compression.
• Updates the ee driver to V1.0.27 to fix issues with IPv6 and SNMP
• Adds path failure detection to the Tru64 Emulex Fibre Channel driver for situations

• Corrects a problem with HSZ events that cause I/O errors rather than doing the

• Corrects an issue in which tape devices that have no ddr entry would not get
compression correctly enabled or disabled as appropriate to the device special file
that was used.
• Fixes a problem that prevents keyboard input during interactive booting (SRM
boot flag i) when in graphics mode on GS1280, ES80, and ES47 AlphaServers.
• Fixes mass storage disk subsystem handling of specific, important events reported

• Corrects default tape devices as /dev/tape/tape0_d1 for dump and restore as per
