The read/write buffer test must be run on a device (disk or tape). Before running

the read/write buffer test, from the SANsurfer FC HBA Manager main window HBA

tree, verify that the HBA port is connected to at least one device.

NOTE: Some devices may not support Read/Write Buffer commands. Check with

your hardware vendor or manufacturer.

You can run the read/write test on all devices attached to the HBA port or to specific

devices attached to the HBA port.
