Troubleshooting
Steps for FC/SCSI
Tape Pipelining 1. Can the UltraNet Edge 3000 communicate with each other?
a. Run the tankio stats 1 command. (See the “TANKIO”
section in this chapter.)
b. Run either the amdenet stats command or the gnic3
stats command. (See the “AMDENET 10/100 WAN or
Maintenance Interface” or the “GNIC3 Gigabit Ethernet
WAN” sections in this chapter).
2. Is the Fibre Channel link up?
a. Run the fcxl2 dump port command.
b. Check the State status. If State is Offline:
— Check to make sure your cables are plugged in appropriately.
— If the UltraNet Edge 3000 is not plugged in to a Switch, but
instead plugged directly into a server or device, make sure the
server or device is configured for Public or Private Loop.
— If you are directly connecting a server or device into the
UltraNet Edge 3000, verify that the HBA, bridge, or device is
included in the supported matrix.
3. Can the UltraNet Edge 3000 access the server(s) and device(s)?
a. Run the fcxl2 dump fcp_login command.
b. Can you see the server or device PortID and WWN?
— Are the Brocade zones configured correctly?
— Refer to Chapter 9 for Brocade zoning examples, or consult the
Brocade Zoning documentation.
4. Are the devices mapped?
a. Run the ttag luns command.
This command outputs a table which displays the UltraNet
Edge 3000’s FC/SCSI Tape Pipelining LUN map. This table
displays what WWN entries in the LUN map have been
statically configured and dynamically discovered.
b. Run the ttag probe command.
