Use host card diagnostics to determine these statuses of the host interface card:
The boot-level diagnostics run automatically and compare writes from and reads to one or more registers on the I/O chip of the host card.
The basic diagnostics are specific to the type of host card: 2-Gb Fibre Channel (FC), 4-Gb FC, InfiniBand, iSCSI, and others.
The basic diagnostics take approximately 30 seconds to complete.
The extended diagnostics are specific to the type of host card: 2-Gb FC, 4-Gb FC, InfiniBand, iSCSI, and others.
The extended diagnostics take approximately five minutes to complete.
If the controller cannot perform the diagnostics, a message appears that indicates that the diagnostics could not start.
You can verify the status of extended diagnostics. The controller responds with one of these statuses:
When you check the status, this information appears:
Diagnostic results include these statuses:
Diagnostic results are stored until diagnostics are run again.
