CONTAP-491908: Failed to get the temp sensors on FC cards in some systems
Issue
- The system is reporting the following "Temp is not readable" alerts for temperature sensors on Fibre Channel (FC) Target+Initiator I/O modules installed in the following systems:
- AFF A1K, AFF A90, AFF A70, AFF C80
- ASA A1K, ASA A90, ASA A70
- FAS90, FAS70
