Oracle Solution for Error ora-19500

ORA-19500: device block size string is invalid

What triggered the Error:

e device block size returned by sequential I/O OSD is invalid

What should we do to fix it:

the block size was set by using the PARMS option of the Recovery Manager ALLOCATE CHANNEL command, then the specified block size must be changed. If no PARMS option was specified on the ALLOCATE CHANNEL command, then this is an internal error that should be reported to Oracle.
