Library Operation Troubleshooting Troubleshooting There are two ways to get information and run tests when errors occur in library operation. Operating system-based support tools allow use of a consistent user interface that spans product lines, as well as remote access. Library firmware-based diagnostics require use of the library’s control panel and display window. Operating System-based Support Tools Several different types of operating system-based support tools exist.
Library Operation Troubleshooting Running Support Tools The Support Tools Manager (STM) can be accessed through any of three interfaces: • xstm (X Window graphical) — for X Windows terminals and workstations. Execute: /usr/sbin/xstm or /usr/sbin/stm/ui/bin/stm -x • mstm (menu-based) — for non-graphics terminals. Execute: /usr/sbin/mstm or /usr/sbin/stm/ui/bin/stm -m • cstm (command line) — for running scripts. Execute: /usr/sbin/cstm or /usr/sbin/stm/ui/bin/stm -c 1.
