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?
