IA: fdisk Profile Keyword

fdisk disk_name type size

fdisk defines how the fdisk partitions are set up on an IA based system. You can specify fdisk more than once. This is what happens by default when fdisk partitions an IA based system:

• All fdisk partitions on the disk are preserved unless you specifically delete them with the fdisk keyword (if size is delete or 0). Also, all existing fdisk partitions are deleted when size is set to all.

• A Solaris fdisk partition that contains a root (/) file system is always designated as the active partition on the disk.

  ---

  IA only -

  The system boots from the active partition by default.

  ---

• If the fdisk keyword is not specified in a profile, the following fdisk keyword is used by default during the installation:

  fdisk all solaris maxfree

• fdisk entries are processed in the order in which they are listed in the profile.

disk_name - Choose where the fdisk partition is to be created or deleted:

• cxtydz or cydz - A specific disk, for example, c0t3d0.

• rootdisk - The variable that contains the value of the system's root disk, which is determined by JumpStart (described in "How the System's Root Disk Is Determined").

• all - All the selected disks.

type - Choose what type of fdisk partition is to be created or deleted on the specified disk:

• solaris - A Solaris fdisk partition (SUNIXOS fdisk type).

• dosprimary - An alias for primary DOS fdisk partitions (not for extended or data DOS fdisk partitions). When deleting fdisk partitions (size is delete), dosprimary is an alias for the DOSHUGE, DOSOS12, and DOSOS16 fdisk types (they are all deleted). When creating an fdisk partition, dosprimary is an alias for the DOSHUGE fdisk partition (a DOSHUGE fdisk partition is created).

• DDD - An integer fdisk partition. DDD is an integer between 1 and 255 inclusive.

  ---

  IA only -

  You can specify this value only if size is delete.

  ---

• 0xHH - A hexadecimal fdisk partition. HH is a hexadecimal number between 01 and FF.

  ---

  IA only -

  You can specify this value only if size is delete.

  ---

The following table shows the integer and hexadecimal numbers for some of the fdisk types.

size - Is one of the following values:

• DDD - An fdisk partition of size DDD (in Mbytes) is created on the specified disk. DDD must be an integer, and JumpStart automatically rounds the number up to the nearest cylinder boundary. If 0 is specified, it is the same as specifying delete.

• all - An fdisk partition is created on the entire disk (all existing fdisk partitions are deleted).

  ---

  IA only -

  This value can be specified only if type is solaris.

  ---

• maxfree - An fdisk partition is created in the largest contiguous free space on the specified disk. If an fdisk partition of the specified type already exists on the disk, the existing fdisk partition is used (a new fdisk partition is not created on the disk).

  ---

  IA only -

  There must be at least one unused fdisk partition on the disk, and the disk must have free space or installation fails. This value can be specified only if type is solaris or dosprimary.

  ---

• delete - All fdisk partitions of the specified type are deleted on the specified disk.
