update-ux checks for required swap space but does not check for
minimum memory. For more information, see “Adjusting Required
Minimum File System Sizes” on page 63 for directions on how to
increase file system sizes.
To update your HP server or workstation to HP-UX 11i v1, it must have
the following:
• All servers require a minimum of 128 MB (256 MB recommended).
Exceptions include the following:
— A-Class servers with HP A5838A LAN-SCSI Combo Card: 256
MB minimum
— All other systems: 64 MB minimum (256 MB recommended)
• Total swap space required when updating or installing is 1 GB. A
minimum of 128 MB of free swap space is required.
• LVM or VxVM partitions:
— / (root): 30 MB free space
— /usr: 220-771 MB free space (see Table 3-5, Free Disk-space
Requirements for /usr and /opt,)
— /stand: 100 MB free space (to expand /stand, see “Increasing
/stand” on page 65)
— /var: 160 MB free space.
— /opt: 225-685 MB free space (see Table 3-5, “Free Disk-space
Requirements for /usr and /opt,” on page 62)
• 4GB root disk, minimum, whether installing or updating to HP-UX
11i v1, with or without an OE. This can be a single disk drive or
combination of physical disks configured as one root volume.
Disk-space requirements for the /usr and /opt partitions depend upon
the update task. Typical requirements for various updates are listed
