Hi

We had issues with one of RAC node going down and were reported saying the LUN/partition table missing due to which the issue occured. But the ASM, database and CRS logs during the issue occurance were analyzed. The analysis does not reveal any evidence pointing to missing partition table OR even block corruption. In fact database was up during said period. Further, team analyzed OS logs during which the issue occured and beyond that timestamp but did not find evidence to show partition table missed or damaged during the period.

So, we would like to know that,

a) Can ASM work for days with partition table on cache while partition table on disk is damaged?

Howdy, Stranger!
