E.g.: $ smartctl -i -d megaraid,0 /dev/sda | grep Serial Serial number: 3JR4LK23M $ smartctl -i -d megaraid,0 /dev/sdb | grep Serial Serial number: 3JR4LK23M This has been a known problem for 9 months: http://sourceforge.net/apps/trac/smartmontools/ticket/46 Unfortunately, the smartctl documentation doesn't mention this bug at all. _______________________________________________ Linux-PowerEdge mailing list [email protected] https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
