Environmental Shutdown Chassis Over Temperature after I/O module changes
Applies to
- ONTAP 9
- AFF A900, FAS9500
- AFF A700, FAS9000
Issue
- During an I/O module (card) swap from one type of module to another, the node experiences an environmental shutdown for temperature issues after ONTAP reboots
- For example, X91440A (40GbE) module replaced with X91153A (100GbE) module:
