Herb, why don't you use client option sets - that way you don't put anything into any of the TSM client directories and furthermore, any change can be done at the TSM server via Web Admin as opposed to having to go to the client and editing dsm.sys/opt files. Joerg Pohlmann "Herb Girard/CanWest/IBM" <[EMAIL PROTECTED]> on 2000-11-07 11:26:53 AM Please respond to "ADSM: Dist Stor Manager" <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] cc: Subject: Configuring dsm.sys and dsm.opt for multiple clients on one host Our environment includes an AIX/HACMP cluster. Some disks are shared, non-concurrently, by the active and standby hosts. We have configured three TSM client nodes, one permanently on each host to back up its non-shared disks, and a third that runs on whichever host is accessing the shared disks. In order to do this, we need separate include/exclude lists for the nodes, which requires separate dsm.sys files. The TSM 3.7 "Installing the clients" manual (p.34) says "Do not put any user created files into /usr/tivoli/tsm/clients/ba/bin, the directory into which the TSM product is installed.... Include-exclude files, dsm.opt and dsm.sys files should not reside in this directory". Later on (p.48) the same manual says that the DSM_DIR environmnet variable must "point to the executable file dsmtca, the resource files, and the dsm.sys file. ... If DSM_DIR is not set, the executables are expected in the default installation directory." Sounded to me like you can;t get there from here. Our solution was to make a copy of /usr/tivoli/tsm/clients/ba/bin, put the second client's dsm.sys and dsm.opt files in there and point to it with DSM_DIR and DSM_CONFIG. This works but seems kind of clumsy. Has anyone else encountered this problem and found a more elegant solution?
