metalink上查詢到doc id為 466673.1，按如下方法解決
檢查clsfmt命令執行狀況:
[root@rac01 bin]$./clsfmt ocr /dev/raw/raw1
clsfmt: received unexpected error 4 from skgfifi
skgfifi: additional information: -2
additional information: 104857600

rac1@oracle[/tmp]> cd 4679769/
rac1@oracle[/tmp/4679769]> cp clsfmt.bin /oracle/product/crs/bin/
使用dd命令將ocr資訊刪除(如果補丁檔案替換後，不dd清理ocr,執行root.sh報錯還是一樣，切記)
[root@rac01 bin]dd if=/dev/zero of=/dev/raw/raw1 bs=1024 count=256
dd: writing `/dev/raw/raw1': no space left on device
101+0 records in
100+0 records out
104857600 bytes (105 mb) copied, 1.98218 seconds, 52.9 mb/s
這時，再次執行root.sh，問題解決

metalink(309815.1): there are two issues with using multipath disks in asm. asm cannot handle seeing the same disk twice. if it does, it will cause an error.
