196 The SCSI Adapters Control Panel Lists No Devices
The SCSI Adapters Control Panel Lists No Devices
Symptom Cause/Solution
The SCSI Adapters
Control Panel does
not list any Fibre
Channel devices.
The system SCSI port driver has not updated its list of devices. Run Disk
Administrator to trigger a refresh, then run the SCSI Adapters Control Panel.
There is a Fibre Channel network or storage device problem. The following
are possible solutions:
– Check all Fibre Channel cable connections. If copper cables are used, check the
length and possible earth plane differential potentials.
– Check the hub/switch status.
– If a RAID is connected, check the LUN status and ensure that there are LUNs
created on the RAID.
– If a switch is connected, verify that the correct port types are being used. Most
RAIDs and HBAs use an F port. JBOD drives and some HBAs use an FL port.
The HP SAN Manager LM QLogic HBA driver uses FL port.
– If you are using JBODs on a switch, and devices repeatedly go missing, update
the firmware to the latest Public Loop capable version. JBOD drives have
exhibited poor recovery behavior after hot-plugging on a switched network.
There is a SAN Manager LM installation or configuration problem. Ensure
that the SAN Manager LM service and drivers are installed and running.
SAN Manager LM’s drivers refused to enable any devices because multiple
SAN databases were detected. Run the SAN Manager LM application from the
host in question. If SAN Manager LM detects multiple databases, remedy the
situation as described on page 201.
The SCSI Adapters control panel can only list 32 devices per adapter. If an
adapter has more attached devices than the control panel can list, the adapter will
disappear from the adapters list in the control panel. This does not prevent you
from using assigned storage.
Note This is a Windows NT limitation.
