Mount Dir: Modify this field to set the root disk, using the standard HP-UX mount directory designations (/, /usr, /stand, /var, /opt, etc.). You can also specify your own mount points, such as /special or /apps.

Avail: Displays the available disk space on the currently selected volume group.

Size:The Size: selection list is used to select the type of sizing, and the text field allows you to enter the size value. The Avail: display shows the unallocated disk space in the volume group currently selected. Changes will be reflected in the Size(MB) and Size Type columns of the file system list window after Add or Modify is selected.

Note that although you can change the size of file systems, Ignite-UX enforces minimum sizes and modifies the sizes upward if required. These sizes are based on the size of the software to be installed and the size defined for the file system.

For information on file system size limitations, see the following documents:

•For HP-UX 11i v3 LVM, see the appendix LVM Specifications and Limitations in the document HP-UX System Administrator's Guide (volume 3): Logical Volume Management available at http://www.hp.com/go/ hpux-core-docs.

•For VxFS on all versions of HP-UX, see the white paper Supported File and File System Sizes for HFS and JFS available at http://www.hp.com/ go/hpux-core-docs.

•For HP-UX versions earlier than 11i v3, see the section Planning to Manage File Systems in the document Managing Systems and Workgroups: A Guide for HP-UX System Administrators, available at http://www.hp.com/go/hpux-core-docs.

The types of sizing available are:

Fixed MB - The selected file system is set to the size entered in the text field.

All Remaining - The selected file system automatically takes over all remaining file system space on the disk or volume group.

Free MB - This selection is useful when you know how much free space you want the volume to have after the system is installed. The size of the volume will be the specified Free MB amount plus the amount required for the selected software.

Free % - This category is similar to free size, but is expressed in percent. It is used if you know how full you want the volume to be in percentage of the volume size. If you indicate 20 percent, then the volume would be 80 percent full after the installation of the selected software.

Range MB - Select this category in the list to set a maximum size for the file system (the minimum is determined by the software selected for the file system). The /usr file system must have sufficient space to accommodate an operating system update. The absolute minimum is 324 MB for a 64-bit system. See the installation guide supplied with your release of HP-UX.

IMPORTANT: Changes are not saved until you click Add or Modify. If you make any changes and then select another tab without using one of these buttons, your changes are not applied and are lost.
