# Test SCSI VERIFY commands issued via the sg ioengine
# All of the jobs below should complete without error
#
# job			description
# precon		precondition the device by writing with a known
#			pattern
# verify00		verify written data on medium only
# verify01		verify each block one at a time by comparing to known
#			pattern
# verify01-two_ios	verify same data but with only two VERIFY operations
# verify11		verify each block one at a time
# verify11-five_ios	verify data with five IOs, four blocks at a time,
#			sending 512 bytes for each IO
# verify11-one_ios	verify all 20 blocks by sending only 512 bytes
