RMAN backup hangs on last channel

DDJun 23 2011 — edited Jun 29 2011
I admin several Oracle DB servers. Recently I have had to run backups by hand. I cannot backup one server though. When I do a "backup database" it will go quickly through the first three channels, and then hang on the fourth. This has happened repeatedly. And I have let run for hours, without completion. Eventually, I ctl c it.

It is configured for four channels and it is backing up to disk (nfs to a SAN), OS is Linux, database version is 11.1.0.7.0.

I also tried running a backup on only one channel and it hung.

I am fairly new to RMAN and would appreciate any ideas on this.

Thanks
