Installing HP-UX 11.0 and Updating HP-UX 10.x to 11.0 HP 9000 Computers Edition 1

22 Chapter 2
Updating an Existing Operating System and Software
HP-UX Update Requirements
NFS Diskless Updating a cluster server to HP-UX 10.30 or later is not supported. NFS
Diskless functionality is not supported in HP-UX 10.30 or later. Do not
update your server to HP-UX 11.0 if you intend for that server to operate
as an NFS Diskless server.
For the latest information on system support, consult your HP sales
engineer.
Fiber Link and HPIB HP-UX 11.0 does not support HPIB, or Fiber Link disks or controller
cards. If you are using this hardware, you should first copy the data from
the device(s), and then disconnect it from your system before updating to
11.0. Failure to do this will not cause a data loss, panic, or other
catastrophic problem, but will result in not being able to access the data
on those devices. Updating before copying the data will render the data
inaccessible, except by reinstalling the earlier release.
Memory and Disk
Space Requirements
• RAM: HP-UX 10.x, including NFS, LAN/9000, and CDE, requires 32
MB of RAM. For HP-UX 11.0, a minimum of 32 MB of RAM is
required, and 64 MB is recommended.
• Before you begin the update, you should be sure your target disk has
the space needed to accommodate the new OS as well as your data
files and all needed backups on disk. You should plan on a minimum
disk size of one GB for a general workstation. Disk usage numbers
will vary by a factor of 20%, depending on the installation.
• File System Increments: Compared to HP-UX 10.20, updating
HP-UX to 11.0 (including NFS, LAN/9000, CDE, and the X
Window System), requires the following additional file system size
for a 32-bit update:
• /usr: 120 MB additional.
• /var: 5 MB additional.
• /opt: 55 MB additional.
Since some of these increases may cause the default file system
size and freespace to be exceeded, see“Adjusting File System Size”,
in Chapter 7, “Troubleshooting,” for the procedure for making
adjustments.
