6–iSCSI Noninteractive Commands
-rwt (Perform Read/Write Buffer Test)

Where:
If you want to restore all areas of the adapter port, either use the A parameter or
use no parameter. Otherwise, specify which areas to restore. For example, the
following command restores the firmware and NVRAM to the factory defaults:
-rdh <hba_port_inst> F N
-rwt
(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.
To do a read/write buffer test, issue the -rwt command as follows:
-rwt <hba_port_inst> [-STOP] [-RWPAT n] [-CNT <Test Count>]
hba_port_inst = Adapter port whose factory settings you want to restore.
A = Restore the factory settings for the entire adapter (firmware
parameters, network parameters, iSCSI name, targets, CHAP
table, NVARAM, and IPSec).
Issuing this command resets the adapter. If you use this option,
no others are necessary.
F = Restore firmware parameters to the factory default values.
Issuing this command resets the adapter.
N = Restore network parameters to the factory default values.
Issuing this command resets the adapter.
I = Restore the iSCSI name to the factory default value.
Issuing this command resets the adapter.
T = Restore the targets to the factory default values.
C = Restore the CHAP table to the factory default values.
V = Restore the NVRAM to the factory default values.
CAUTION!
Before doing a read/write buffer test, make sure that the adapter does not
have any outstanding I/O operations.
