-rwt

(Perform Read/Write Buffer Test)

CAUTION!

Before doing a read/write buffer test, make sure that the HBA does not have any outstanding I/O operations.

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 non-destructive to disk data.

To do a read/write buffer test, enter the -rwtcommand as follows:

-rwt <hba_port_inst> [-STOP] [-RWPAT n] [-CNT <Test Count>]

Where:

–STOP= Stops the test if a failure occurs.

–RWPATn = Sets the pattern to write to the buffer, one of the follow- ing:

n = 1 (8 bytes of 0x55h) (default) n = 2 (8 bytes of 0x5Ah)

n = 3 (16 bytes of 0xAAh) n = 4 (16 bytes of 0xFFh)

hba_port_inst = The HBA 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. Enter a number between 2–(2^31) for more than one test.

To continue, press ENTER.
