%ì VAX-11 Librarian V04-00`ïT†%„™vV†%„™ ü 5TESTDEV­vV†%„™ 1 TESTDEVK This utility program performs read-IO's to a disk and produces performance statistics. Format: TESTDEV disk-device= Values typical of normal VMS activity would be reflected by: /BLOCK=4 /SEEK=MEGABYTE=100 2 ParameterK Specifies the (logical or physical) device name of the disk to be tested. 2 Qualifiers /BLOCK_PER_IO /BLOCK_PER_IO[=number]F Specifies the size of each IO, in blocks. The default is 1 block/IO. /COVERAGE /CO VERAGE=patternC Specifies the seek pattern. The default is random seek within the default or specified range.+ Pattern: RANDOM[=seed] (default=12345678) or SEQUENTIAL9 Sequential coverage operates over a single stream only./IO /IO[=number]J Specifies the total number of IO's to perform. The default is 1000 IO's. /SEEK_RANGE /SEEK_RANGE=(boundary[,...])A Specifies the logical or physical maximum area to seek on disk.: Boundary: MEGABYTE[=value] (default= 0 for entire-volume) or# FROM_LBN=lower_number (inclusive)! TO_LBN=upper_number (inclusive)/STREAM /STREAM[=number]E Specifies the number of parallel IO's to perform to the device. The! default is a single (1) stream.ww
