PRODUCT: HP Tru64 UNIX [R] 5.1B SOURCE: Hewlett-Packard Company ECO INFORMATION: ECO Name: T64V51BB22-C0019200-19212-E-20030710 ECO Kit Approximate Size: 2.38MB Kit Applies To: HP Tru64 UNIX 5.1B PK2 (BL22) ECO Kit CHECKSUMS: /usr/bin/sum results: 22975 2440 /usr/bin/cksum results: 3929474812 2498560 MD5 results: 533ed96955274d8dc05725c4dbe012ad SHA1 results: 065d66ad36490733fabadc42218b9d065c4445f0 ECO KIT SUMMARY: A dupatch-based, Early Release Patch kit exists for HP Tru64 UNIX 5.1B that contains solutions to the following problem(s): Mandatory patch for the following Gigabit Ethernet LAN-On-Motherboard (LOM) and Network-Interface-Card (NIC) implementations: HP DS25 AlphaServer GbE LOM , UTP copper 3X-DEGXA-SA PCI GbE NIC, MMF 3X-DEGXA-TA PCI GbE NIC, UTP copper HP has determined during on-going Tru64 UNIX stress testing that certain Gigabit Ethernet LAN-on-Motherboard (LOM) and Network-Interface-Card (NIC) implementations may, in response to a rare trigger event described below, experience a DMA Write Engine loss of synchronization when transferring data from adapter/chip memory to host CPU memory. Based on our laboratory analysis, we believe that this loss of synchronization could potentially manifest itself in one or a combination of several ways: o Data integrity issues o Transmit time-out o Network interface stops transferring packets entirely o Bad checksums in the output of "netstat -s" The Patch Kit Installation Instructions and the Patch Summary and Release Notes documents provide patch kit installation and removal instructions and a summary of each patch. Please read these documents prior to installing patches on your system. The patches in this ERP kit are scheduled to be available in the next mainstream patch kit - HP Tru64 UNIX 5.1B Patch Kit 3. INSTALLATION NOTES: 1) Install this kit with the dupatch utility that is included in the patch kit. You may need to baseline your system if you have manually changed system files on your system. The dupatch utility provides the baselining capability. 2) The patch in this ERP kit does not have any file intersections with any other ERP available at this time for this product version. 3) This ERP kit will NOT install over any Customer Specific Patches (CSPs) which have file intersections with this ERP kit. Contact your normal Service Provider for assistance if the installation of this ERP kit is blocked by any of your installed CSPs. INSTALLATION PREREQUISITES: You must have installed HP Tru64 UNIX 5.1B PK2 (BL22) prior to installing this Early Release Patch Kit. KNOWN PROBLEMS WITH THE PATCH KIT: None. RELEASE NOTES FOR T64V51BB22-C0019200-19212-E-20030710: Release Notes This document summarizes the contents and special instructions for the Tru64 UNIX V5.1B patches contained in this kit. For information about installing or removing patches, baselining, and general patch management, see the Patch Kit Installation Instructions document. 1 Release Notes This Early Release Patch Kit Distribution contains: - fixes that resolve the problem(s) reported in: o 221-2-242 * for Tru64 UNIX V5.1B T64V51BB22AS0002-20030415.tar (BL22) The patches in this kit are being released early for general customer use. Refer to the Release Notes for a summary of each patch and installation prerequisites. Patches in this kit are installed by running dupatch from the directory in which the kit was untarred. For example, as root on the target system: > mkdir -p /tmp/CSPkit1 > cd /tmp/CSPkit1 > > tar -xpvf DUV40D13-C0044900-1285-20000328.tar > cd patch_kit > ./dupatch 2 Special Instructions There are no special instructions for Tru64 UNIX V5.1B Patch C192.00 3 Summary of CSPatches contained in this kit Tru64 UNIX V5.1B PatchId Summary Of Fix ---------------------------------------- C192.00 Mandatory patch for DS25 AlphaServer or DEGXA 4 Additional information from Engineering None 5 Affected system files This patch delivers the following files: Tru64 UNIX V5.1B Patch C192.00 ./sys/BINARY/bcm.mod CHECKSUM: 21662 491 SUBSET: OSFHWBIN540 [R] UNIX is a registered trademark in the United States and other countries licensed exclusively through X/Open Company Limited.
