In a typical system there is usually one adapter and multiple channels, and each channel has a slave and a master. The adapter/channel/master/slave status of each hard disk is given in the Loc (location) columns of the Free Disks and Array Disks lists. 1.0.M M: Master S: Slave Channel Adapter 0 is used for PATA drives 1 and above is used for SATA drives Figure 2.15 Loc Column Information In Figure 2.15, 1.0.M means the hard drive is attached to Adapter 1, Channel 0, and the drive is set to Master. The following is a list of all possible combinations: Parallel ATA 0.0.M 0.0.S 0.1.M 0.1.S Adapter 0, Channel 0, Master Adapter 0, Channel 0, Slave Adapter 0, Channel 1, Master Adapter 0, Channel 1, Slave Serial ATA 1.0.M 1.1.M 2.0.M 2.1.M Adapter 1, Channel 0, Master Adapter 1, Channel 1, Master Adapter 2, Channel 0, Master Adapter 2, Channel 1, Master Note: There is no such thing as Slave drive in Serial ATA.
