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

• 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 involving
hung N_Ports of a storage controller in a switched fabric environment.
• Updates Mobile IPv6 code to be compliant with the latest RFC.
• Modifies the DDR database to add support for the HP DAT72X6 changer.
• Updates the bcm driver to V1.0.23 to fix issues with Jumbo frames.
• Corrects a problem with HSZ events that cause I/O errors rather than doing the appropriate
retries so the I/O can be successful.
• Adds read/write ability to XP control ports.
• 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 by the
HSG80 and HSG60 array controllers.
• Corrects default tape devices as /dev/tape/tape0_d1 for dump and restore as per device
naming convention in V5x versions.
Changes I/O retry processing when a command time out is encountered. With this change,
the retry code attempts to take advantage of other active paths during retries if command
time outs are encountered.
• Corrects a problem with the DAT160 tape drive in which tape devices with no ddr entry
would not get compression correctly enabled or disabled as appropriate to the device special
file that was used.
• Adds ddr.dbase support for the DAT160 tape drive.
• Corrects A potential security vulnerability.

• Allows the hwmgr redirect scsi command to work with lockmode 4.
• Fixes device recovery timing by improving the chances for a problem disk to recover.
• Allows the first path to be removed with hwmgr if it is stale.
