RMAN-03009: failure of backup command on t1 channel at 03/14/2013 01:03:55
ORA-19502: write error on file "incr2_810002889_17o4fae9_1_1", block number 1 (block size=512)
ORA-27030: skgfwrt: sbtwrite2 returned error
ORA-19511: Error received from media manager layer, error text:
ANS0278S (RC157) The transaction will be aborted.
其中ORA-19511: Error received from media manager layer, error text這一句提示很明顯，與media manager有關，這裏使用的是TSM，就是TSM出了問題。
原因主要有如下:
第一：磁帶的空間不夠
第二：TSM備份軟件出現問題
第三：DRIVER 壞了或者不夠用的
