I have to tell that MD3000i has 2 iscsi controler and 4 ethernet
ports.

CentOS is connected with 2 ethernets cables (1/controler) to the
MD3000i. Does the 2 devices are 2 controlers ?

Why have I these error in message log ?
Mar  5 11:14:36 nas1 kernel: Buffer I/O error on device sdc, logical
block 0
Mar  5 11:14:36 nas1 kernel: end_request: I/O error, dev sdc, sector 0
Mar  8 11:54:16 nas2 kernel: Buffer I/O error on device sdc, logical
block 438666224
Mar  8 11:54:16 nas2 kernel: end_request: I/O error, dev sdc, sector
3509329792

Thanks for reading.
Derrick.
