Per metalink note,
Subject: RMAN Duplicate fails with ORA-19870, ORA-19507, ORA-27029 and ORA-19511
Doc ID: *562780.1*
In this case the failing routine:
ORA-19507: failed to retrieve sequential file,
ORA-27029: skgfrtrv: sbtrestore returned error
The actual eror is:
ORA-19511: Error received from media manager layer, error text:
Vendor specific error: Cannot find requested element ERR(2:OBE_INVARG)
If you are restoring to a new host there will be additional media manager
environment variables that need to be set to tell the media manager that a
backup created on one host, is to be restored to another.
The specific error: Cannot find requested element ERR(2:OBE_INVARG), is a media manager error, pleas contact your media manager vendor.
There looks to be the issues with Media manager.
Hope this helps.

I agree Hemant. It does seem to be this error"sbtrestore: Job44240 thread3696: CVArchive->open() failed." My sysadmins have opened a call with Commault the backup software vendor. I will be talking with them soon.
In the mean time I have run a RESYNC CATALOG and performed a full backup and tried the DUPLICATE again with the same errors.
