Continuous Access Storage Appliance Installation and Maintenance Guide
Hardware device failure
When a storage device fails, it is marked as failed by the appliance and monitored for recovery.
A hardware device failure, which occurs when a storage device develops a physical defect,
causes the following error message to appear:
RPIC DPF : IOFD dvfd : Device hardware failure : adapter %d bus %d
SCSI %d LUN %d : DPF Lun %d : Status %x Sense %x ASC %x ASCQ %x
This error condition is recorded in the event log.
The first four values, all expressed in decimal format, represent the identification numbers for
the adapter, bus, SCSI port, and physical LUN, respectively. The fifth number, also in decimal
format, repeats the physical LUN number. The final four values, all hexadecimal, represent
back-end SCSI information, in the following order: SCSI Status Code, Sense Code, Additional
Sense Code (ASC), and Additional Sense Code Qualifier (ASCQ). These four values may be
interpreted by referencing either SCSI documentation or the vendor product specification.
Hardware device recovery
A hardware device recovery code is reported when a failed storage device, which is being
monitored for health, is replaced or restored to operation. The following message appears:
RPIC DPF : IOFD rcvy : Device recovered : adapter %d bus %d SCSI %d
LUN %d
This message is entered into the event log. Variables are used in the above format because the
actual values will be dependent on the specifics of the event. The four decimal numbers
included in this message indicate the adapter identification number, the bus number, the SCSI
port number, and the physical LUN number, respectively. This message is used for information
purposes only and is not indicative of a problem within the storage network.
