Introduction
Your Easy Setup hp-ux workstation comes with hp-ux preinstalled and configured. You can use
this default setup, called Easy Setup Instant Ignition, or cold install the software yourself from the CD.
The benefit of installing the system yourself is that you have more control over the file system layout.
On the default system:
The two disks are placed in one volume group (meaning they appear to the system as one disk).
The disks are striped (meaning they are accessed simultaneously to improve performance).
There is equal swap on both disks (which gives the same performance benefits as striping).
This setup is explained in detail in The Default File System on page 18.
Decide How to Proceed
If you can use the default setup, go to the Instant Ignition Overview on page 13 in this manual.
If you want to install from CD, go to CD Install Overview on page 11 in CD Install for EasySetup hp-ux 11.0.
If you need to learn more, use the following tables to determine which method to use.

Instant Ignition Overview
If youve chosen Easy Setup Instant Ignition, you will do the following:
You may need to refer to CD Install for Easy Setup hp-ux 11.0 in certain situations.
For More Information on Easy Setup

If you questions, comments, or suggestions, please send email to:
We respond to all email.
A Connect the systemto the network.
Youll be connected in five easy steps. See Task A: Connect the System
to the Network on page 14.
B Modify your filesystem layout.
The system can be used as soon as it is connected to
the network. However, you will probably want to
make some modifications to your file system.
Note: If you want to increase the size of/, you must
install from CD.
See Task B: Modify the File
System Layout on page 16.
C Choose how tomount your NFS
file system.
You can mount NFS file systems two ways:
With automounting. You can use either AutoFS
(default) or automounter. AutoFS offers several
advantages over automounter; however, someapplications may have problems with AutoFS.
The older automounteris slower than AutoFS and
limits data files to a maximum of 2 GB.
With static mounts (using /etc/fstab). In
some situations, static mounts are the best
solution.
See Task C: Configure for Your
NFS File System on page 23.
D Perform optional,but recommended,
modifications to
the setup.
You may want to:
Set up NIS+ client services.
Add local users.
Modify kernel parameters.

Using the Easy Setup Instant Ignition System
Task A: Connect the System to the Network
14
Task A: Connect the System to the Network
1. Gather system information.
You need the:
Hostname. The hostname must be 8 characters or fewer (for example, snoopy). The fully
qualified domain name must be 64 characters or fewer (for example: snoopy.hp.com).
IP address
Subnetwork mask
Gateway IP address
DNS domain name (for example, hp.com)
DNS server IP address
NIS domain name if using NIS (for example, hp.com)
Time
Time zone
New root password
Network settings. Check with your network administrator to verify the duplex setting (full,
half, or auto) and speed (10 or 100 Mbits/sec) of your network connection.
2. Check connections and settings.
If you are using a graphics monitor, make sure the keyboard, mouse, and monitor are attached
properly.
If you are using a serial (RS-232/terminal) console, you must disconnect the keyboard, mouse,
and monitor from the system. Use common settings (baud rate = 9600, data bits = 8, parity =none, stop bits = 1, flow control = none). To connect from a Windows system or Sun system,
see Working with Consoles and Serial Terminal Emulators on page 44 in CD Install for Easy
Setup hp-ux 11.0 for more information.
3. Turn on the system and check for activity.
The LCD display on the system indicates various system checks, then displays either:
Console is SER_1 for terminal (for example, DEC VT100 on serial port 1)
Console is GRAPHx for graphics, where x is the slot number of the graphics card
Shortly after this message appears, you should see activity on your monitor or terminal. Note the
following:
If there is no activity on your graphics monitor, press Tab. The system cycles through variousmonitor settings at 20-second intervals. When you see activity, press Enterto save the setting.
If your graphics monitor still shows no activity, try connecting with a serial line. See Working
with Consoles and Serial Terminal Emulators on page 44 in CD Install for Easy Setup hp-ux
11.0.
If you still do not see console activity, power off the workstation, verify your connections and
settings, and try again.

4. Configure your network connection.
You must perform this step if you are using the built-in network interface. For PCI LAN interfaces,
see Setting Up an Optional Network Card on page 52 in CD Install for Easy Setup hp-ux 11.0.
a. When prompted, press any key to stop the boot process.
b. Execute the appropriate command:
If your network uses auto detect, execute:
co lanconfig auto
If your network uses full or half duplex, execute:
co lanconfig speed/duplex_setting
wherespeedis 10 or100 (Mbits/sec), and duplex_settingis full_dx orhalf_dx.
For example:
co lanconfig 100/full_dx
Check with your network administrator for the proper settings. Note that this only affects the
built-in LAN interface.
c. Execute the boot command to restart the boot process:
bo
d. When the system asks if you want to interact with IPL (initial program loader), press N.
NOTE This is a very important step that will affect your system performance. If you did not stop the boot
process in time, perform these steps by rebooting after you complete the system setup.
5. Enter networking information when prompted.
When you select the NIS server, enter a dot (.) in the NIS server field to indicate that you want to
locate the NIS server automatically. You must enter the NIS domain name to allow the system toautodetect and use either the master or slave servers. After you enter the dot (.), the install
interface will say (not set). Ignore this message.
Whats Next?
You can use the system as soon as it is connected to the network. However, you will likely want to:
Modify the file system. The first two pages of the next section (Task B: Modify the File System
Layout on page 16) explain how to set up and manage the file system.
Configure NFS. See Task C: Configure for Your NFS File System on page 23 for a description
of the two configuration methods.
For example, if you are mounting /home using NFS, you may want to perform both of these tasks. Inthis case, you would comment out the mounting of/home in /etc/fstab. Then you could delete the
corresponding logical volume used for/home locally, which would turn the disk space used by
/home into unallocated space.

Task B: Modify the File System Layout
Understanding the File System and Logical Volumes
On hp-ux, disk space is managed through logical volumes. Logical volumes are implemented by the
Logical Volume Manager (LVM), a set of commands for handling your system's entire disk storage.
LVM combines one or more physical disk devices into a complete disk management system, allowing
you to allocate disk space according to current need.
Before you plan your disk layout, understand the following terms:
Physical Volume a hard disk.
Volume Group a collection of one or more physical volumes. Each collection appears to the
operating system as a single disk. A physical volume can belong to only one volume group.
Logical Volume a slice of a volume group (similar to a Sun Slice).
Like disks, logical volumes can hold file systems, raw data areas, dump areas, or swap areas.Unlike disks, logical volumes let you choose their size when you create them and later expand that
size. You can also spread logical volumes across multiple disks.
Physical/LogicalExtents the smallest unit of space that LVM can allocate.
Physical extent is the breakdown of the physical volume. Logical extent is the break-down of the
Logical Volume. The default size for each of these is 4 MB. When you create file systems, swap,
or raw slices, the system rounds to multiple of 4 MB.
For More Details on File System Layout
Go to docs.hp.com and search for striped or swap to access a wealth of information on these
topics and on file system layout.

Task B: Modify the File System Layout
17
Understanding Swap Space
Swap space is initially allocated when you configure your disks. There are three types of swap space:
Device Swap This type of swap space occupies a logical volume (slice), which is then reserved
expressly for paging and swapping.
File System Swap You can use available space in a file system for swap space. Setting up such
file system swap space allows for extra swap if there is occasional need for more than the allocated
device swap space. It is used only when device swap space is insufficient.
Pseudo-Swap You can use system memory as a third type of swap space. In hp-ux, swap space
can consist of up to seven-eighths (87.5%) of system memory capacity.
By default, pseudo-swap space is configured to be available. If you do not want to use it, re-set the
tunable system parameter, swapmem_on, to 0 (off).
Swap Priority
When you add swap areas, you can assign a priority to each. Priorities range from 0 to 10:
The system uses the swap areas with higher priority first. The system gives device swap priority over
file system swap when each has the same priority.
Follow these guidelines:
If you have multiple swap devices on different physical hard disks and the swap devices have
similar performance, assign each an identical priority. This allows the system to use each of them
on an interleaved basis, which enhances performance.
Assign higher priorities to the swap areas that have faster performance and lower priorities to areas
that are slower.
File system swap should only be used as an overflow to device swap.
0 (highest priority)1 (default)
10 (lowest priority)

The Default File System
NOTE The CD Install for Easy Setup hp-ux 11.0 manual explains file system configuration in detail.
Looking at the default file system layout will help you decide how to lay out your own file system.
The pre-loaded system is configured as follows:
The two hard disks are set up in one volume group.
The two disks are grouped in a way that makes them appear to the system as one disk.
The two disks are striped.
Disk striping can increase the performance of applications that read and write large, sequentially
accessed files. Data access is performed over the two disks simultaneously, resulting in a
decreased amount or read/write time as compared to the same operation on a single disk.
There is equal swap space on both disks.
This allows the system to access swap areas on the two disks simultaneously, giving the same
performance benefits as striping.
Below are approximate file system sizes for a default system with two 18 GB disks striped and 4 GB
RAM. Additionally, lvol2 and lvol4 are each 4096 MB and are used as swap space. About 22.8
GB of disk space is unallocated.

Using the System Administration Manager (SAM)
HPs System Administration Manager (SAM) helps you perform most system administration tasks.
For example, SAM lets you add, modify, or delete file systems, logical volumes, or volume groups.
To start SAM, login as root, then execute sam.
The X-Windows version of SAM uses a graphical user interface. If you are using a terminal(non-graphics monitor), you will have the text version of SAM. Use the Tab and Arrow keys to
navigate in the text version.
Working with Logical Volumes
Creating a Logical Volume
You have at least one volume group: vg00. You may have created other volume groups during
installation. You can use SAM to create, modify, or delete logical volumes within your volume
groups.
1. Start SAM. Go to Disks and File Systems, then go to Logical Volumes.
2. Select Actions > Create.
3. Click Select Volume Group.
4. Select one of the existing volume groups, then clickOK.
5. Create the logical volume. Go to Define New Logical Volume(s) and set the following:
LV Name: the default naming convention is lvol1, lvol2, lvol3, etc.
LV Size in MB: the approximate free MB remaining on the disk(s) is noted below the LV Size
field.
Usage: select File System, Swap Device, orNone (Raw) from the drop-down list, then
specify the necessary information.
If you select File System, specify the:
Mount Directory (for example, /scratch or/project)
Modify FS Defaults: VxFS (journaled) is the default. It is a Veritas file system, which can
handle large volumes of data. HFS (non-journaled) is a plain UNIX file system (UFS). Set
the following:
Access: read/write or read only
Allow Large Files: allows files larger than 2 GB (by default, this option is off; we
recommend you turn it on)
When to Mount: select Now and Every System Boot
VxFS Options: use the defaults (see the online help for more information)
If you select Swap Device, specify:
Swap Priority

6. Go to Modify LV Defaults. Note the following:
General: When you set up a swap device, select Use Contiguous Allocation for best
performance (recommended, but not required). You can turn it off, however, if the LVM
system cannot allocate that much contiguous space.
Mirroring: Available only when you install the optional Mirror Disk System software package,which lets you create a mirror of the working disk. For more information, see the Mirror-UX
documentation.
Striping: Available if you have two or more disks in your volume group. If you use striping,
we recommend you set the stripe size to 64 KB.
7. Select Add and OK to exit the screens.
The logical volume is now created.
Modifying or Removing a Logical Volume
Do not delete any logical volumes that hold standard hp-ux file systems, such as /, /opt, /stand,
/tmp, /usr, or/var.
1. Start SAM. Go to Disks and File Systems, then go to Volume Groups.
2. Select the logical volume you want to modify or remove.
3. Select either:
Actions > Modify. Make your changes, then clickOK.
Actions > Remove. ClickOK.
Extending a Logical Volume with SAM
You must unmount a logical volume before you extend it. Keep in mind that certain file systems
cannot be unmounted while the system is in multiuser mode; you may need to boot to single-user
mode.
The / file system cannot be extended unless you have On-Line VxFS.
If you purchased the On-Line VxFS software, you can extend a file system while it is mounted.
For unmounted or advanced VxFS file systems, do the following:
1. Start SAM. Go to Disks and File Systems, then go to Logical Volumes.
2. Select the logical volume to extend.
3. Select Actions > Increase Size. Enter the new size, then clickOK.
NOTE You cannot decrease the size of a logical volume. To make a logical volume smaller, you must back
up the data in the logical volume, remove the logical volume, recreate the volume with the reducedsize, and restore the data. (Make sure the reduced size is large enough to hold the data you need
to restore.)

Extending a Logical Volume in Single-User Mode
1. Boot the system to single-user mode:
a. Boot the system. When prompted, press any key to stop the boot process.
b. Restart the boot process. Execute:
bo
c. When asked if you want to interact with IPL (initial program loader), pressY.
d. At the ISL prompt, execute:
hpux -is
2. After the system boots, execute the logical volume extend command:
lvextend -L size_in_MB /dev/volume_group/logical_volume
Example:
lvextend -L 600 /dev/vg00/lvol5
NOTE If you do not know the logical volume name, use cat to list /etc/fstab. This shows the logical
volume names.
3. Execute the extend file system command:
extendfs -F FS_type /dev/volume_group/logical_volume
Example:
extendfs -F vxfs /dev/vg00/lvol5
4. Reboot the system or execute:
init 3 (to switch to multi-user mode)

Working with Volume Groups
You can create new volume groups or extend existing volume groups if you have additional disks.
Creating a Volume Group
1. Start SAM. Go to Disks and File Systems, then go to Volume Groups.
2. Select Actions > Create. The Create New Volume screen appears.
3. Create the volume group. Use the interface to:
Select New Volume Group Name. The default naming convention is: vg00 (root volume),
vg01, vg02, vg03, etc.
Select the disk(s) you want to add to the volume group.
4. If desired, create logical volumes. Go to Define New Logical Volume(s) and specify the
information required (see Creating a Logical Volume on page 19).
5. Select OK and Add to exit the screens.
Extending or Removing a Volume Group
You can extend a volume group only if you have additional disks.
You cannot remove the root volume group (vg00).
1. Start SAM. Go to Disks and File Systems, then go to Volume Groups.
2. Select the volume group you want to extend or remove.
3. Select either:
Actions > Extend, then Select the Disk(s) to add to the volume group. ClickOK.
Actions > Remove. ClickOK.

Configuring Automounting Using AutoFS
AutoFS is the default for both the HP factory preinstalled system and the CD-installed system. Follow
these steps if you are using automounter and want to change to AutoFS.
1. In /etc/rc.config.d/nfsconf, the following activates AutoFS:
AUTOMOUNT=1AUTOFS=1
2. Modify any scripts you have that kill and restart your automount (AutoFS rarely needs to be
restarted). If you need to make changes to your automounting maps, run the
/usr/sbin/automount program after modifying the maps.
NOTE Make sure none of your maps are executable. If the x permission bit is set on any automounting
map file, the system hangs when a mount is attempted. Set permissions to 644 (rw for owner, r for
group and others).
3. Increase the block transfer size to improve performance:
a. On the HP client, increase the read and write block sizes from the default value of 8192 to
32768:
i. Create the /etc/auto_home file with the contents:
* NFSServername:ExportDirectory/&
For example:
* dragon:/export/home/&
ii. In the /etc/auto_master file, add the following line:
/home auto_home -rsize=32768,wsize=32768
NOTE Do not use tabs use only spaces. If you use a tab, AutoFS will not work.
b. Make sure the /etc/nsswitch.conf file has the following:
automount: files [NOTFOUND=continue] nis
c. Restart AutoFS. Execute:
/usr/sbin/automount
NOTE AutoFS creates any nonexistent directories between the root directory and the configured mount point.
For example, if you attempt to mount a remote file system on /dir1/dir2, AutoFS creates /dir1
and /dir1/dir2, then mounts the remote file system on it.

Configuring Automounting Using automounter
Follow these steps if you are using AutoFS and want to change to automounter.
1. Stop the Automount daemon:
/sbin/init.d/nfs.client stop
2. In /etc/rc.config.d/nfsconf, set the following:
AUTOMOUNT=1
AUTOFS=0
3. On the HP client, add the following line to /etc/auto_master:
/home auto_home
4. Specify the servers:
a. Create /etc/auto_home.
b. Add the following line to /etc/auto_home:
* servername:/path/&If you have multiple servers, you must add this line for each server. For example:
* dragon:/export/home/&
* laser:/export/home/&
5. Reboot the system.
Configuring the nsswitch.conf File
The nsswitch.conf file is put into place by Easy Setup. It must be set up according to your needs.
The default file is commented for your guidance.
Using Static Mounts
To add a static NFS mount:
1. Export the file system on the server.
2. Login as root and execute: sam
3. Go to Disk and File Systems, then to File Systems.
4. Select Actions > Add A Remote File System > Using NFS.
5. Enter the information, then clickOK.
This mounts the remote file system and updates the /etc/fstab file to always mount on boot up
(assuming you left when to mount defaults checked).
