Linux disks and partition names may be different from other operating systems. You need to know the names that Linux uses when you create and mount partitions. Here's the basic naming scheme:
The first hard disk detected is named
The second hard disk detected is named
and so on.
The first SCSI CD-ROM is named
The partitions on each disk are represented by appending a decimal
number to the disk name:
sda2 represent the first and
second partitions of the first SCSI disk drive in your system.
Here is a real-life example. Let's assume you have a system with 2
SCSI disks, one at SCSI address 2 and the other at SCSI address 4.
The first disk (at address 2) is then named
and the second
sdb. If the
sda drive has 3 partitions on it, these will be
sda3. The same applies to the
sdb disk and its partitions.
Note that if you have two SCSI host bus adapters (i.e., controllers), the order of the drives can get confusing. The best solution in this case is to watch the boot messages, assuming you know the drive models and/or capacities.
