/boot. The kernel files and bootloader sector will be associated with this device. For most common cases, the first DASD or SCSI LUN will be used, but for some unusual cases, this may not be the case. The device number will be used when re-ipling the post-installed system.

- Partitions section. Selecting opens a dialog box. Some or all of the fields can be edited, depending on whether the partition information has already been written to disk.: Used to modify attributes of the partition currently selected in the
- It should only be used if you have experience using RAID. To read more about RAID, see the Red Hat Enterprise Linux Deployment Guide.: Used to provide redundancy to any or all disk partitions.To make a RAID device, you must first create software RAID partitions. Once you have created two or more software RAID partitions, selectto join the software RAID partitions into a RAID device.
17.14.3. Partition Fields
- Device: This field displays the partition's device name.
- Mount Point/RAID/Volume: A mount point is the location within the directory hierarchy at which a volume exists; the volume is "mounted" at this location. This field indicates where the partition is mounted. If a partition exists, but is not set, then you need to define its mount point. Double-click on the partition or click the button.
- Type: This field shows the partition's file system type (for example, ext2, ext3, or vfat).
- Format: This field shows if the partition being created will be formatted.
- Size (MB): This field shows the partition's size (in MB).
- Start: This field shows the cylinder on your hard drive where the partition begins.
- End: This field shows the cylinder on your hard drive where the partition ends.
