Diagnostic Fibre Channel Device

For each FC port there will be a Diagnostic Fibre Channel Device presented to the Fabric. There
will be one per active FC physical port; this means there are wo ports for an HP D2D41 12, 4312
or 4324 appliance.
The Diagnostic Fibre Channel device can be identified by the following example text:
Symbolic Port Name "HP D2D S/N-CZJ1440JBS HP D2DBS Diagnostic Fibre Channel
S/N-MY5040204H Port-1"
Symbolic Node Name "HP D2D S/N-CZJ1440JBS HP D2DBS Diagnostic Fibre Channel
S/N-MY5040204H"
A virtual driver or loader would be identified by the following example text:
Symbolic Port Name "HP D2D S/N-CZJ1440JBS HP Ultrium 4-SCSI Fibre Channel
S/N-CZJ1440JC5 Port-0"
Symbolic Node Name "HP D2D S/N-CZJ1440JBS HP Ultrium 4-SCSI Fibre Channel
S/N-CZJ1440JC5"
In the above the S/N-CZJ1440JBS for all devices should be identical. If this is Node Port 1, the
Node Name string will be as above but, if Port 2, the Node Name string will end with "Port-2".
Often the diagnostic device will be listed above the other virtual devices as it logs in first, ahead
of the virtual devices. The S/N-MY5040204H string is an indication of the QLC HBA's SN not any
SN of an appliance/node.
At this time these devices are part of the StoreOnce VTL implementation and are not an error or
fault condition. It is recommended that these devices be removed from the switch zone that is also
used for virtual drives and loaders.
