RMAN mixed backups -on tape and disk

Hello Gurus,

I have a very basic question as you may call it. Suppose I have a MML for sbt_tape backups. I have a daily incrementals scheduled using this MML ,which are going on tape.

If I run an RMAN incremental backup from cmdline and target it to DISK, will this interfere the chain of my incremental backups to tape using MML?

What I mean is , suppose I have an incremental to tape on Day1 at night, and following day Day2 I took an incremental to DISK in afternoon, so when my next incremental to tape will run at Day2 night, RMAN should give me changed blocks since last night ( Day1 night, prev tape incremental). Is my understanding correct? Or, RMAN will just give me changed data blocks since the Day2 afternoon incremental to DISK?

Howdy, Stranger!
