from discovering unnecessary disk controllers. For optimal performance, where practical,
dedicate HBAs for disk and tape.
NOTE: Overlapping zones are supported.
Use the StoreOnce Management GUI to find out the WWPN for use in zoning. The WW port
names are on the
VTL-Libraries-Interface Information tab.
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.
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 example 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 is 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. HP recommends removing these devices from the switch zone that is also used for
virtual drives and loaders.
