Displaying the Host Card Diagnostic Results
Use the host card diagnostics to determine these statuses of the host card:
- Boot-level diagnostics determine basic functionality of the host card.
- User-initiated basic diagnostics validate basic operations.
- User-initiated extended diagnostics examine functionality in depth.
Boot-Level Diagnostics
The boot-level diagnostics run automatically and compare writes from and reads to one or more registers to the I/O chip of
the host card.
Diagnostic results include these statues:
-
Optimal status – All ports or initiators can transport I/O.
-
Degraded status – One or more ports or initiators cannot transport I/O but at least one port or initiator can connect and transport I/O.
-
Failed status – The host card cannot transport I/O on any port or initiator.
In addition, boot-level diagnostics might return these messages:
-
New Host Interface Card – A previously empty host interface slot has been filled.
-
Removed Host Interface Card – A previously populated host interface slot is now empty.
-
Host Card Replaced by Card with Same Board ID – An existing host card is replaced with a different host card that has the same board ID.
-
Host Card Replaced by Card with Different Board ID – An existing host card is replaced with a different host card that has a different board ID.
User-Initiated Diagnostics
User-initiated diagnostics are specific to the type of host card: 2-Gb Fibre Channel (FC), 4-Gb FC, InfiniBand, iSCSI, and
others.
Diagnostic results include these statuses:
-
Optimal status – All ports or initiators can transport I/O.
-
Degraded status – One or more ports or initiators cannot transport I/O but at least one port or initiator can connect and transport I/O.
-
Failed status – The host card cannot transport I/O on any port or initiator.
Diagnostic results are stored until diagnostics are run again.
If you try to retrieve the diagnostic results before they are complete, the remaining time for completion appears.
