磁盤 write same failed 報錯處理

一、查看報錯信息： #dmesg -T [Tue Mar 17 13:10:16 2020] megasas: FW status 0x3 [Tue Mar 17 13:10:16 2020] megasas: FW status 0x3 [Tue Mar 17 13:10:16 2020] megasas: FW status 0x3 [Tue Mar 17 13:10:16 2020] megasas: FW status 0x3 [Tue Mar 17 13:10:16 2020] megasas: FW status 0x3 [Tue Mar 17 13:10:16 2020] megasas: FW status 0x3 [Tue Mar 17 13:10:16 2020] sd 0:2:4:0: [sde] tag#0 FAILED Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK [Tue Mar 17 13:10:16 2020] sd 0:2:4:0: [sde] tag#0 CDB: Write same(16) 93 00 00 00 00 02 6b 90 4e 68 00 00 00 10 00 00 [Tue Mar 17 13:10:16 2020] blk_update_request: I/O error, dev sde, sector 10394553960 [Tue Mar 17 13:10:16 2020] sde: WRITE SAME failed.
