io3000 classes and subtests
io3000 consists of a series of tests grouped together in classes beginning
with verification of the most basic functionality and progressing toward
more complex functionality. Each class is broken down into subtests
which target specific functionality.
The following sections describe the classes and individual subtests.
io3000 classes
io3000 has 10 classes of tests shown in Table 31.
Table 31 Classes of io3000 tests
Class Name Description
1 SAGA CSR Test Verifies successful writes and reads of
SAGA CSRs.
2 SAGA Memory
Test
Verifies the functionality of SAGA
context/shared memory and prefetch
memory.
5 SCSI Disk
Interface Test
Verifies the ability to successfully issue
SCSI commands to every selected disk or
Fibre Channel target.
6 Channel Mode
Test
Verifies the ability to successfully build
and use SAGA channels in all the
supported modes. Also, every channel can
be verified to be usable.
7 DMA Boundary
Conditions Test
Verifies that various DMA conditions and
every possible interrupt vector work
correctly. Also verifies every possible
interrupt vector.
8 MultiDisk
Concurrency
Test
Queues up all selected disks for
simultaneous transfers. In this test, all
disks operate in a parallel fashion.
