RMAN not retrying on media manager errors

I'm using Oracle 10g, RMAN and TDPO (the TSM client for Oracle). I'm trying to do a PITR to a non-production machine, but RMAN is intolerant of any media manager problems that crop up, so things like this

ORA-19511: Error received from media manager layer, error text:

    ANS1017E (RC-50) Session rejected: TCP/IP connection failure

and this

ORA-19511: Error received from media manager layer, error text:

    ANS1314E (RC14) File data currently unavailable on server

result in an immediate 'failover to previous backup'. The first error was caused by a transient network problem; I suspect the second was just bad luck as the file was being reclaimed by the TSM server when TDPO asked for it.

Both these errors would have gone away if RMAN had tried again, so is there any way I can tell it to retry on error? If not, is there something else I could do to improve the situation?

Thanks
- Ian
