NCR - 53C8xx SCSI I/O Processor Tests
These sections describe the individual NCR 53C8xx (SCSI I/O Processor)
tests.
The firmware now provides support for testing of multiple SCSI
controllers within PCI configuration space. This means that the SCSI
diagnostics can now be run on multiple SCSI controllers. This is “only
”
true for any firmware supported SCSI devices.
Examples of where SCSI tests run include:
1. On a PowerPC board that has two (2) SCSI devices on the board.
2. On a PowerPC board that has one (1) SCSI device on the board and
one (1) SCSI PMC/PCI card attached to the board.
3. On a PowerPC board that has one (1) SCSI device on the board and
a SCSI PMC attached to the PMC Carrier plugged into the
backplane of the chassis.
Entering NCR without parameters causes all NCR tests in the order shown
in the table below.
To run an individual test, add that test name to the NCR command.
The individual tests are described in alphabetical order on the following
pages.
