(Perform Read/Write Buffer Test
)
The read/write buffer test writes an 8- or 16-byte pattern to the disk’s buffer and
reads the written buffer back. It is nondestructive to disk data.
reads the written buffer back. It is nondestructive to disk data.
To do a read/write buffer test, issue the -rwt command as follows:
-rwt <hba_port_inst> [-STOP] [-RWPAT n] [-CNT <Test Count>]
Where:
To continue, press ENTER.
-save
(Save Host Configuration)
To save the configuration (in XML) of all adapters detected, issue the -save
command as follows:
-save <file_name>

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)
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-
ber between 2–(2
31
) for more than one test.
