-rwt (Perform Read/Write Buffer Test)

SN0054667-00  C

6-23

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. 

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.

To save the configuration (in XML) of all adapters detected, issue the -save 

command as follows:

-save <file_name>

                                                                                           

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-

ber between 2–(2

31

) for more than one test.
