reads the written buffer back. It is nondestructive to disk data.

CAUTION!

Before doing a read/write buffer test, make sure that the adapter does not

have any outstanding I/O operations.

–STOP = Stop the test if a failure occurs.

–RWPAT n = Set the pattern to write to the buffer, one of the following:

n = 1 (8 bytes of 0x55h) (default)

n = 2 (8 b.0tes of 0x5Ah)

n = 3 (16 bytes of 0xAAh)

n = 4 (16 bytes of 0xFFh)

hba_port_inst = The adapter port tested.

-CNT = Used with Test Count to set the number of tests, with one test

as default.

Test Count = The number of tests to do, with one as default. Type a num-
