Cause

This error means that the JBOD identified in the alert is somehow misconfigured - most likely due to a faulty piece of hardware contained within it.

A common cause of this error is a disk that has failed in such a way that it is reported as "absent" rather than "faulted" in the configuration.

The problem may also be a faulty SIM or a SIM with mismatched firmware to the other SIM in the JBOD.

Check this by reviewing the hardware configuration in the BUI:


Maintenance > hardware
Select the correct JBOD identified by the <Serial Number> in the alert and click on "Show Details"

Alternatively in CLI type:


S7000:> maintenance hardware list
S7000: maintenance hardware> select chassis-00X show                     
where chassis-00X is the chassis with the name identified in the alert.

Solution

If a disk is marked as absent, then check it is seated correctly. Try reseating it and see if it comes back online.

If a SIM is faulted or has mismatched firmware also try reseating this. Before reseating a SIM first check that you have a valid second path to the disks in the JBOD.

This can be seen from the BUI:


maintenance > hardware
Check the number of PATHS listed against the appropriate disk shelf.

or from CLI:


S7000: maintenance hardware select chassis-00X show
where chassis-00X is the name of the chassis identified in the alert.
The number of paths is listed under Properties:

If reseating does not fix the issue, then raise a Service Request with Oracle Support to get the issue investigated and/or the problem part replaced.
