150 Troubleshooting the Pathlight VX
Troubleshooting Cable Connections
Cable problems on the Pathlight VX can be difficult to diagnose, because of the number and different types
of cables used in the system. Typically, the Pathlight VX determines that communication errors are
occurring on components connected by the suspect cable, not the cable itself.
If the Pathlight VX reports that a cable has failed, perform these steps:
1 Verify that the connectors on the cable are seated tightly.
If the cables are seated tightly and the problem still exists, replace the cable.
2 After replacing the cable or correcting a connection problem, power off and start up the Pathlight VX.
Refer to Shutting Down the Pathlight VX
on page 19 and Starting Up the Pathlight VX on page 17.
3 Verify that the cable problem is resolved.
4 Verify that all components associated with the identified cable are operating normally.
If the problem is resolved, close the service ticket. Refer to Closing Service Tickets
on page 138.
The problem is not resolved, perform these steps:
a. Capture the Pathlight VX system state. Refer to Capturing a System State
on page 144.
b. Modify the ticket according to the troubleshooting steps taken. Refer to Modifying Service
Tickets on page 137.
c. Contact the ADIC Technical Assistance Center. Refer to Getting More Information or Help
on
page 4.
Troubleshooting Temperature Errors
Typically, temperature problems are caused by incorrect room temperature, poor air circulation inside the
Pathlight VX rack or components, or a malfunctioning fan. For information on temperature requirements,
refer to ‘Environmental Requirements’ in the Pathlight VX Site Preparation Guide.
Use this procedure if a temperature problem is reported or suspected.
1 Check the ambient temperature of the room containing the Pathlight VX to verify that the temperature
falls within the specified range.
2 Verify that all unoccupied disk slots contain a filler module, that all cover plates are in place on the
Pathlight VX components, and that filler plates/bezels are installed over unused space in the rack. All
filler plates must be in place to enable adequate air circulation.
3 Inspect for adequate air circulation inside the rack. Some racks may provide additional fans to improve
air circulation. Check the fan for proper operation. Clean or replace any air filter as necessary.
4 When a FRU reports a temperature problem, verify that its fan (if installed) spins freely and does not
have excessive dust buildup. If it is necessary to replace the FRU, contact ATAC for assistance. Refer
to Getting More Information or Help
on page 4.
CAUTION
When replacing cables on the Pathlight VX, use new cables instead of
swapping FC cables from other components. Swapping cables can
interfere with Pathlight VX host connectivity and device mapping.
