OpenVMS__SHADOW ALPSHAD01_070 Alpha V7.0 Volume Shadowing ECO Summary

NOTE: An OpenVMS saveset or PCSI installation file is stored on the Internet in a self-expanding compressed file. The name of the compressed file will be kit_name-dcx_vaxexe for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha. Once the file is copied to your system, it can be expanded by typing RUN compressed_file. The resultant file will be the OpenVMS saveset or PCSI installation file which can be used to install the ECO. Copyright (c) Digital Equipment Corporation 1996. All rights reserved. ******************** WARNING! ******************** * * * Engineering has discovered a problem with this * * ECO kit and has requested that it be placed on * * hold. They are currently researching the * * problem. * * * **************************************************** PRODUCT: Volume Shadowing for OpenVMS (Phase II) OP/SYS: OpenVMS Alpha V7.0 COMPONENT: Shadow Driver Bugcheck SOURCE: Digital Equipment Corporation ECO INFORMATION: ECO Kit Name: ALPSHAD01_070 ECO Kits Superseded by This ECO Kit: None. ECO Kit Approximate Size: 882 Blocks Kit Applies To: OpenVMS Alpha V7.0 System/Cluster Reboot Necessary: Yes ECO KIT SUMMARY: An ECO kit exists for Volume Shadowing on OpenVMS Alpha V7.0. This kit addresses the following problems: o Failures occur during attempts to start copies or restart copies, usually after a node halt, shutdown or reboot. Additional symptoms observed include inconsistent values for HBS_CIP when compared to SHADOW_MAX_COPY, negative values for HBS_CIP and copies that should continue start over from the beginning. o If a DCD copy is interrupted by a mini-merge, the copy will restart at 0% copied (LBN 0) rather than continuing from where it left off. DCD copies should restart at the last copied LBN after it was interrupted by mini-merge. o System hangs may occur when I/Os pending to a shadow set do not complete. o A two member shadowset with member index 0 a copy target and index 1 the only source member experiences a node failure on a node serving the disks. The source member goes "available". The source index is never packacked and the system remains with the set hung in mount verification forever. o UCB$L_MAXBCNT is not set up for system disks before the first writes are enabled for that device. The attempt to issue a write without having this field initialized results in a SHADDETINCON bug check. INSTALLATION NOTES: In order for the corrections in this kit to take effect, the system must be rebooted. If the system is a member of a VMScluster, the entire cluster should be rebooted.
