The read/write buffer test sends specified data through the SCSI Write Buffer command to a target device (disk). It then reads the data back through the SCSI Read Buffer command and compares the data for errors. The test also compares the link status of the target before and after the read/write buffer test. If errors occur, the test indicates a broken or unreliable link between the HBA port and the target.

NOTE:

„Under Solaris, this feature is disabled if you are using the driver from the OS installation CDs (QLC driver).

„Some targets may not support read/write buffer commands. Check with your hardware vendors or manufacturer.
