"device block size %s is invalid"
*Cause: the device block size returned by sequential I/O OSD is invalid
*Action: If 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.
