how does db2 calculate from which lsn to replay transaction when doing crash recovery

I think that each container is marked with a lsn that is committed the last time,when crash recovery ,db2 compare each container's mark and the min(lowtranlsn,minbuflsn) in the logs, and do replay from MIN（lowist container mark, min（minbuflsn，lowtranlsn））.

does it do like this?

thanks
