-eb end_block
Specifies the ending block number (hexadecimal) within the file stream. The
default is 0.
-p pass_count
Specifies the number of passes to run the exerciser. If you specify 0, the exerciser
runs forever or until you enter Ctrl/C. The default is 1.
-l blocks
Specifies the number of blocks (hexadecimal) to exercise. This option has
precedence over the -eb option. If only reading, and you specify neither l nor
-eb, the exerciser reads until it reaches the end-of-file (EOF). If writing, and
you specify neither l nor -eb, the exerciser writes for the size of the device. The
default is 1.
-bs block_size
Specifies the block size (hexadecimal) in bytes. The default is 0x200 except for
tape drives, which default to 0x800. The maximum block size allowed with
variable length block reads is 0x800 bytes.
-bc block_per_io
Specifies the number of blocks (hexadecimal) per I/O operation. The default is 1.
-d1 buf1_string
Specifies a character string that is processed by the eval command and then
loaded into buffer1 to initialize the buffer. By default, the buffer is loaded with
alternating 5s and As (hexadecimal).
-d2 buf2_string
Specifies a string that is processed by the eval command and then loaded into
buffer2 to initialize the buffer. By default, the buffer is loaded with alternating
5s and As (hexadecimal).
-a action_string
Specifies an exerciser ''action string,'' which determines the sequence of read,
write, and compare operations on various buffers. The default action string is
''?r.'' The action string characters are:
r Read into buffer1
w Write from buffer1
R Read into buffer2
W Write from buffer2
