System Configuration Requirements for AS/U

An HP 9000 Series 700 or 800 computer with HP-UX version 10.20 or later . Verify by using the uname -a command.

The HP LAN/9000 Link networking hardware installed (on some systems, the link, or hardware card, is factory installed).

A minimum of 32 MBytes of RAM. This information appears on your screen during reboot. If you missed the information when you rebooted, you can type the following to see this information (if you are logged in as root):

/etc/dmesg (note: output is in KBytes. Convert to MBytes)

A minimum of 46 MBytes of free disk space is required to install the Advanced Server/9000 software. Additional disk space (minimum 150 MBytes) is required for Advanced Server/9000 operations such as adding users, creating printer spool files, and creating shares.

	NOTE: Depending on your system size and configuration, additional disk space and memory may be required for AS/U system configuration and operation.

To see the available disk space on your system, type:

/usr/bin/bdf
(note: output is in KBytes. Convert to MBytes if consulting the following table)

If the disks on your system are configured to use LVM, the minimum available disk space for installation of Advanced Server/9000 or migration to it should be as follows:

If the disks on your system are configured to use LVM, the recommended minimum available disk space for operation of Advanced Server/9000 should be as follows:

The Advanced Server/9000 event logs, ACL files, user account files, sharefile, and spooler information (such as submitted files, spooler state and so forth) will be saved in /var/opt/asu/lanman. Therefore, you may want to allow additional disk space in this directory based on your usage predictions.

Ensure that you have adequate free disk space in /home or other volumes where your user files will be saved. This amount of disk space depends on your usage of Advanced Server/9000.

Note: On LVM configurations, you cannot use SAM to expand the /var volume. You must use the command line interface. See the HP-UX System Administration Tasks for information on how to expand the /var volume.

Swap space required for AS/U is as follows (this is in addition to swap space required by other applications):

AS/U minimal configuration 7.5 MB swap space
AS/U large configuration 15.0 MB swap space
Each ten clients beyond the first ten 3.0 MB swap space
(need for lmx.srv processes)

Minimal configuration is defined as < 10 each configured users, printers, queues, and shares. Large configuration is defined as 10000 configured users per domain, or 256 printers, 256 queues, and 5000 shares per server. Using this information as a guideline, scale the swap space on your system as appropriate for your configuration. Swap space can be viewed and configured using the HP-UX SAM utility.

Supported Advanced Server/9000 maximums are as follows:

The HP LAN 9000 networking fileset installed and configured. To verify that, examine the /etc/hosts file to ensure that your hostname is there by typing: grep hostname /etc/hosts

Also, ensure that the IP address for your hostname is different than the loopback address configured for localhost (for example, not 127.0.0.1). If this is not true, go to the HP-UX System Administration Manager (SAM) and modify the configuration of the LAN card (lan0) to set up the network. For further information on IP addresses and subnetting, see the Hewlett-Packard link manual for the type of LAN installed .

A hardware drive for the distribution media (such as CD ROM) that contains the Advanced Server/9000 software.

An existing netdemon must not be running. Verify that the netdemon process is no longer running. Type:

ps -ef | grep netdemon

If a netdemon process exists, you must explicitly kill that process:

kill -9 xxxx (where xxxx is the pid of the netdemon process.)
