Partitioning the Hard Disk

Using the Format Utility to Create fdisk Partitions

Only one Solaris OS fdisk partition can exist on a hard disk. You use the format utility to create fdisk partitions. First, execute the format command and select the appropriate disk (in this example disk 1): # format AVAILABLE DISK SELECTIONS: 0. c0d0 /pci@0,0/pci-ide@7,1/ide@0/cmdk@0,0 1. c0d1 /pci@0,0/pci-ide@7,1/ide@0/cmdk@1,0 Specify disk (enter its number): 1 If the disk does not already have a disk label on it you will be prompted to label it now: selecting c0d1 [disk formatted] Disk not labeled. Label it now? y The format menu is displayed. Enter the fdisk command to display the fdisk menu: FORMAT MENU: disk - select a disk type - select (define) a disk type partition - select (define) a partition table current - describe the current disk format - format and analyze the disk fdisk - run the fdisk program repair - repair a defective sector label - write label to the disk analyze - surface analysis defect - defect list management backup - search for backup labels verify - read and display labels save - save new disk/partition definitions inquiry - show vendor, product and revision volname - set 8-character volume name ! - execute , then return quit format>fdisk The fdisk menu displays information about the disk size, cylinder size, and current fdisk partitions. In this example, the disk does not have any fdisk partitions: Total disk size is 13328 cylinders Cylinder size is 945 (512 byte) blocks Cylinders Partition Status Type Start End Length % ========= ====== ============ ===== === ====== === SELECT ONE OF THE FOLLOWING: 1. Create a partition 2. Specify the active partition 3. Delete a partition 4. Change between Solaris and Solaris2 Partition IDs 5. Exit (update disk configuration and exit) 6. Cancel (exit without updating disk configuration) Enter Selection: 1 To create a single fdisk partition using the whole disk, select option 1 and enter the number of the type of disk partition that you would like to create. Select option 1 which is a Solaris OS fdisk partition. Select the partition type to create: 1=SOLARIS2 2=UNIX 3=PCIXOS 4=Other 5=DOS12 6=DOS16 7=DOSEXT 8=DOSBIG 9=DOS16LBA A=x86 Boot B=Diagnostic C=FAT32 D=FAT32LBA E=DOSEXTLBA F=EFI 0=Exit? 1 You will then be prompted to enter a percentage that indicates how much of the disk you would like to use to make this fdisk partition. Select 100, which represents 100%, to use the whole disk. Specify the percentage of disk to use for this partition (or type "c" to specify the size in cylinders). 100 Because this is going to be a non-bootable partition, do not make the partition active. Only the boot partition should be set as active. Select n for no. Should this become the active partition? If yes, it will be activated each time the computer is reset or turned on. Please type "y" or "n". n Select option 5 to save the fdisk partition configuration. Note: If you want to have multiple operating systems on a drive, create multiple fdisk partitions using fdisk option 1. The following is an example of a disk with three fdisk partitions supporting three different operating systems: Total disk size is 13328 cylinders Cylinder size is 945 (512 byte) blocks Cylinders Partition Status Type Start End Length % ========= ====== ============ ===== === ====== === 1 Win95 FAT32 1 5331 5331 40 2 UNIX System 5332 9329 3998 30 3 Solaris2 9330 13327 3998 30
