When archiving to disk, CA Disk automatically adjusts the optimal blocksize value for the device type of the volume; that is, half track blocking on 3375s and 3380s, and full track blocking on other devices. You can override the defaults by specifying sysparm ARCDSKBZ. The blocksize selected for a disk device is also used for any tape or 3480 copy that is being created concurrently.
If you have more than one device type in your archive pool, use sysparm ARCDSKBZ to specify a blocksize appropriate for all devices; that is, one that provides optimal performance and space usage on all the devices.
