We check the Solidfire display below error, I can found NetApp KB "NVRAM device problems detected, metadata drive will be removed" but the error not same as "error=deviceCapacitanceOffThePack", should I require open support case?
NVRAM device problems detected, metadata drive will be removed. Contact NetApp support, error=deviceCapacitanceOffThePack 3.926F
Definitively open a support case for all such suspicious errors. Warnings may be temporary, but Errors could become critical.
In this case, after this error maybe one of your nodes lost Drive 0 following this error (check Drives > Available), so although redundancy has most likely been restored by redistributing data on the remaining nodes, you may have one non-functioning metadata drive, which isn't good.
If HCI Solidfire in private subnet without send to ActiveIQ outside, but the mNode can reach vCenter only, if Solidfire have warning or error, could vCenter detect the Solidfire problem and send the email notification to outside?
