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

• Increases the default limit of DLI packets to 16 K and makes the limit tunable. This
corrects a problem in which attempts to sent packets larger than 5000 bytes (jumbo
packets) can fail.
• Updates DDR for the MSA array controller and for other future devices.
• Adds recognition for possible future devices.
• Fixes various problems in the bcm driver for DEGXA Gigabit Ethernet adapters.
• Updates ICMP code to add redirect timeout support and non-modifiable route
table entries.
• Provides modifications for emx hardware.
• Provides device support for the SDLT160/320 tape drive.
• Fixes various problems in the ee driver for DE60x.
• Sets a software limit to prevent serious performance problems that can occur when
TCP connections that have an rate-limit enforced by a downstream network device
overrun the device.
• Corrects a problem in which /sbin/ddr_config does not accept values for
ReadyTimeSeconds larger than 255. The new limit is 86400 seconds (24 hours).
• Fixes problems with NUMA disk statistics
• Fixes a KMF problem that can happen if some of the nodes in cluster are rebooted
and a device is shared by all the nodes.
• Changes the CAM subsystem message that is printed to the error log on a recovered
read error from "bad block number" to "block number."
• Corrects a problem that can cause a core dump when the fwupgrade command is
executed with qualifiers.
• Enhances HP-XP Array controller support.
• Corrects several potential security vulnerabilities where, under certain
circumstances, system integrity may be compromised. These may be in the form
of improper file or privilege management.
• Fixes an I/O hang condition on Fibre Channel.
• Corrects a problem in which Tru64 UNIX sees an HP-XP RAID array controller as
a disk after an HP-XP storage device is added to the system.
• Updates the Radeon graphics driver to not reject multi-headed configurations.
• Fixes a memory fault condition in the emx driver that occurs when responding to
an inquiry command from a remote port in the fabric.
• Updates DDR for the SDLT600, DLT VS, SuperDLT1, SDLT320, and VS series of
tape drives.
• Modifies a script that sets up entries in /dev to solve the following problem: When
creating a cluster, certain old style /dev entries should be removed, but in some
configurations they are not.
• Provides support for the Ultrium 2 SCSI tape drive.
