Disk Space and Memory Requirements

update-ux checks for required swap space but does not check for minimum memory. For more information, see “Adjusting Required Minimum File System Sizes ” in Appendix B “Known Problems and Troubleshooting” for directions on how to increase file system sizes.

To update your HP server or workstation to HP-UX 11i, 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 3-6 “Free Disk-space Requirements for /usr and /opt”)
- /stand: 100 MB free space (to expand /stand, see “Increasing /stand” in Appendix B “Known Problems and Troubleshooting”)
- /var: 160 MB free space.
- /opt: 225-685 MB free space (see Table 3-6 “Free Disk-space Requirements for /usr and /opt”)
4GB root disk, minimum, whether installing or updating to HP-UX 11i, 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 next.

Table 3-6 Free Disk-space Requirements for /usr and /opt

HP-UX 11i Update Task	/usr	/opt
10.20 -> 11i default update: HPUXBase, HPUXBaseAux, network drivers, CDE and OnlineDiag	400 MB	225 MB

10.20 -> 11i Enterprise OE	731 MB	685 MB
10.20 -> 11i Mission Critical OE	771 MB	685 MB
10.20 -> 11i Technical Computing OE	731 MB	885 MB
10.20 -> 11i Minimal Technical OE	681 MB	665 MB
11.0 -> 11i default update: HPUXBase, HPUXBaseAux, HWEnable11i, BUNDLE11i, network drivers, CDE and OnlineDiag.	220 MB	225 MB
11.0 -> 11i OE	531 MB	435 MB
11.0 -> 11i Enterprise OE	591 MB	635 MB
11.0 -> 11i Mission Critical OE	611 MB	635 MB
11.0 -> 11i Technical Computing OE	591 MB	955 MB
11.0 -> 11i Minimal Technical OE	531 MB	575 MB
11i (no OE) -> 11i OE	320 MB	415 MB
11i (no OE) -> 11i Enterprise OE	372 MB	645 MB
11i (no OE) -> 11i Mission Critical OE	410 MB	645 MB
11i (no OE) -> 11i Technical Computing OE	372 MB	820 MB
11i (no OE) -> 11i Minimal Technical OE	372 MB	385 MB

Extra space needed with TCOE and MTOE

Cold-installing the HP-UX 11i Technical Computing OE and the Minimal Technical OE installs all CDE languages, rather than just a selected language. To remove unneeded CDE language bundles after installing the TCOE or MTOE, list them using swlist and remove unneeded bundles using swremove. See Chapter 7 “Verifying System Migration” for example uses of swlist and swremove.




	IMPORTANT: Any last-minute install and update issues are described in the Read Before Installing or Updating to HP-UX 11i booklet supplied with the HP-UX 11i CD or DVD media. Be sure to review that booklet as well as Appendix B “Known Problems and Troubleshooting” before continuing.
