This patch corrects the following: - DDR subsystem updated to handle SCSI devices returning a non-standard device type. - Fixes two problems with ddr_config. ddr_config previously would sometimes build partial device records. ddr_config on Digital UNIX V4.0 was not compatible with input files created prior to this version. - Adding device recognition for TZS20. - Fixes a problem in which the DDR database (/etc/ddr.dbase) limited the maximum block size of "unknown" tape drives to 64 kilobytes. The maximum block size is changed to 16 megabytes.
