SMC Library Names The library name on the open_ibmatl (″libname″) or mtlib -l libname parameter determines whether a 3494 library or an SMC library is being used. If the library name is a logical operating system SMC library name then the libsmc support is used. Otherwise, the lmcpd support is used. For example, SMC libraries on AIX are named smc0, smc1, and so on. To issue an mtlib query library command on AIX to a 3584 library named smc0: mtlib -l smc0 -qL To issue an mtlib command on Linux to a 3584 library named IBMchanger0: mtlib -l IBMchanger0 -qL Volume Categories The 3494 library supports the grouping of one or more volumes into categories that can be assigned by an application and operations that can specify a category only rather than a specific volume. SCSI Medium Changers do not provide a similar function. All volumes in an SMC library are category 0000, the NULL category. 210 IBM Tape Device Drivers Installation and User's Guide
