The hsmmaxrecalltapedrives option controls how many tape drives participate in tape-optimized recall processing.
By limiting the available tape drives for tape optimized recall processing, you can prevent all drives from being blocked. In this way, some drives remain accessible for transparent recall processing and migration.
If the value of the hsmmaxrecalltapedrives option is greater than the number of tape drives available, a recall thread waits for the next available tape drive. If you plan to run tape-optimized recalls processes in parallel, the number can be decreased accordingly for parallel processing without running out of tape drives.
If the maxnummp option is defined on the Tivoli® Storage Manager server, you can set the hsmmaxrecalltapedrives option to a number that is less than or equal to the maxnummp option. You can reserve tape drives for other operations if you set the number lower than the maxnummp option and the maximum number of tape drives.
