The performance problem is most evident with large file transfers, but also occurs with smaller transfers. 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 will also be available in the next mainstream patch kit - HP TruCluster Server 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 TruCluster Server 5.1B PKssb (BLssb) prior to installing this Early Release Patch Kit. KNOWN PROBLEMS WITH THE PATCH KIT: None. RELEASE NOTES FOR TCV51BBssb-C0003400-19120-E-20030630: Release Notes This document summarizes the contents and special instructions for the TruCluster Server 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 96011 DE_G06530 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 SPECIAL INSTRUCTIONS for TruCluster Server V5.1B Patch C34.00 The following patch should be installed on ALL EV7 architecture systems in a TruCluster. The patch only needs to be applied to the EV7 class systems. However, the patch is structured so that it can be safely applied across the cluster to different architecture systems as well if clusterwide patch consistency is desired. The operation of these systems will not be affected. 3 Summary of CSPatches contained in this kit TruCluster Server V5.1B PatchId Summary Of Fix ---------------------------------------- C34.00 ERP for Memory Channel I/O Performance on EV7 4 Additional information from Engineering None 5 Affected system files This patch delivers the following files: TruCluster Server V5.1B Patch C34.00 ./usr/opt/TruCluster/sys/rm.mod CHECKSUM: 01378 427 SUBSET: TCRBASE540 [R] UNIX is a registered trademark in the United States and other countries licensed exclusively through X/Open Company Limited.
