The Question is: We are running a mixed cluster consisting of a VAX 6410 and and Alpha 2100 under OpenVMS 7.1. Last week we pulled the VAX node out of the cluster and reconfigured it as a standalone node. We then restored an image backup on the VAX system made prior to the reconfiguration and restored it as a cluster member. The VAX system boots back into the cluster just fine. However, when we reboot the Alpha system, DECwindows no longer appears to be loading correctly. As the Alpha boot process completes, we see t he following error messages: %INSTALL-I-FAIL, failed to create shared linkage entry for DISK$AXPVMSSYS:<SYS0.SYSCOMMON.SYSLIB>DECW$XLIBSHR.EXE -INSTALL-E-NOTSHRADR, CDE$UNIX_ROUTINES is not installed with shareable address data %INSTALL-I-FAIL, failed to create shared linkage entry for DISK$AXPVMSSYS:<SYS0.SYSCOMMON.SYSLIB>DECW$XTLIBSHRR5.EXE -SYSTEM-F-VA_IN_USE, virtual address already in use %INSTALL-I-FAIL, failed to create shared linkage entry for DISK$AXPVMSSYS:<SYS0.SYSCOMMON.SYSLIB>DECW$XMLIBSHR15.EXE -SYSTEM-F-VA_IN_USE, virtual address already in use %INSTALL-I-FAIL, failed to create shared linkage entry for DISK$AXPVMSSYS:<SYS0.SYSCOMMON.SYSLIB>DECW$MRMLIBSHR12.EXE -SYSTEM-F-VA_IN_USE, virtual address already in use %INSTALL-I-FAIL, failed to create shared linkage entry for DISK$AXPVMSSYS:<SYS0.SYSCOMMON.SYSLIB>DECW$DXMLIBSHR12.EXE -SYSTEM-F-VA_IN_USE, virtual address already in use The Alpha console then displays the DECwindows background, but does not display a boot prompt. Killing the DECW$SERVER0 process and rerunning DECW$STARTUP.COM does not correct the problem. The Alpha was not modified and was not rebooted while we had the VAX out of the cluster. We have also reinstalled DECwindows (version 1.4) on the Alpha, which had no impact on the problem. Any suggestions as to what the problem is? The Answer is : This does not initially look related to the removal of the OpenVMS VAX node from the cluster, and its subsequent addition back into the cluster. Please consider an upgrade to DECwindows version V1.2-5. Check the values of the GH_RES_CODE and IMGREG_PAGES system parameters. Also make sure that the DECwindows AUTOGEN pass has not been disabled (via DECW$IGNORE_AUTOGEN or otherwise), and ensure that changes to these and to other key parameter settings have not been disabled via MODPARAMS.DAT, and run a pass of AUTOGEN on the target system. This should reset the above values to permit the system to load DECwindows. If the AUTOGEN and reboot does not succeed in loading DECwindows (and assuming that MODPARAMS.DAT has been cleaned up), please contact the Compaq Customer Support Center directly for assistance.
