Troubleshooting the Upgrade Procedure
When upgrading the Entry Shared PowerEdge VRTX storage subsystem to Fault Tolerant configuration, it
is critical that you follow the steps in order. Observe the following precautions:
• Back up all critical data to a storage independent of the PowerEdge VRTX storage subsystem.
• Record the storage configuration and mapping information to a storage independent of the
PowerEdge VRTX storage subsystem.
• Observe safety guidelines when handling electronic equipment.
• Do not exert too much pressure when removing and reinstalling hardware components.
Failure to follow the steps in this document may result in the following issues:
• Shared storage virtual disk to server node mapping may be lost or changed.
• Fault tolerance may be reported as degraded in CMC.
• The PowerEdge VRTX system may fail to become operational.
Basic Troubleshooting Steps
For any issue, perform the following checks:
• All hardware components are properly seated. This includes the hard-drive backplane, the backplane
expander boards, the Shared PERC 8 cards, and any other hardware that you may have reinstalled
during the upgrade procedure.
• All the cables are connected and routed in the chassis as instructed in this document.
• All components have been updated to the latest driver or firmware version.
Troubleshooting the Storage Subsystem
If the basic troubleshooting steps did not resolve the issue, perform the following steps:
1. Turn off all the server modules and the PowerEdge VRTX system.
2. Remove the shared drives from the PowerEdge VRTX system.
3. Turn on the PowerEdge VRTX system and confirm if fault tolerance is enabled.
4. Turn off the PowerEdge VRTX system.
5. Reinsert the shared drives in the system.
6. Turn on the PowerEdge VRTX system.
7. Log in to the CMC GUI and confirm the shared storage virtual disk to blade mapping is correct:
a. ClickChassis Overview → Storage → Virtual Disks → Assign.
b. If the mapping no longer exists or is incorrect, reconfigure the mapping in the Assign page in
CMC. Power cycle the system and confirm the mapping changes.
If Virtual Disk mapping is still missing or incorrect; perform the following steps:
8. Turn off all the server modules and the PowerEdge VRTX system.
