Hi. I am currently using SATA drives in a RAID 1 configuration. I am looking to use SAS drives instead of SATA. As my first experiment I have plugged my SAS drive into a system and I have noticed that Linux sees the individual ports on the device as separate devices, so I have /dev/sdc and /dev/sdd which are both the same physical device. So if I have a system with 2 SAS drives I am going to have 4 devices representing the two physical drives. So my question is how do I create RAID 1 sets for partitions on these types of drive? My existing system carves 3 RAID 1 volumes from a pair of drives. How do I translate this to the dual port SAS devices? Thanks Simon. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
