System Requirements

System Firmware Requirements

Make sure the firmware shipped with the system meets the minimum firmware requirements for the system for the latest HP-UX 11i v3 (B.11.31) release. HP strongly recommends you review the minimum system firmware matrix for HP-UX 11i v3 (B.11.31) systems at the HP Technical Documentation Web site:

Disk Space Requirements for a Cold-Install

Table 2-1 “File Partition Disk Space Allocation by OE ^, ” lists the amount of disk space allocated for the indicated partitions during a default cold-install for each Operating Environment.

	NOTE: During installation, Ignite-UX (on the File System tab) shows a higher percentage of disk space used than the information in Table 2-1 shows. The minimums enforced by Ignite-UX ensure that the cold install completes successfully without filling a file system. This difference exists on all versions of Ignite-UX.

Disk Space Requirements for an Update

To ensure a successful update to HP-UX 11i v3, make sure that you have at least as much disk space allocated to the file partitions listed in Table 2-1 “File Partition Disk Space Allocation by OE ^, ”, and that each partition (most importantly, /usr, /opt, and /var) has at least 10-20 percent free space to allow for any growth.

Disk Space Allocation for File Partitions

Depending on your system’s purpose, you may need to determine how much disk space you will need for each file partition before you cold-install or update to HP-UX 11i v3. For example, if you plan to install applications from other vendors, you may need to modify the size of the /opt partition to accommodate their size. Depending on how much disk space is available, you can change the partition size to meet your needs. For information about modifying your file system, see the HP-UX System Administrator’s Guide at the HP Technical Documentation Web site: http://docs.hp.com

	NOTE: If the default size for the /stand partition is too small for your environment, do not use the lvextend command to increase the size of the /stand partition; doing so may render your system unbootable. Instead, use either System Management Homepage to extend the /stand partition or Ignite-UX recovery to create a recovery image and resize the /stand partition. You can boot from the recovery image and resize /stand as you recover the system. For help using System Management Homepage, refer to the smh (1M) manpages or the HP SMH Online Help included with the product. For help creating a recovery image, refer to the Ignite-UX Administration Guide available on the HP Technical Documentation Web site: http://docs.hp.com
