x86: Creating an x86 Install Server With CD Media

The install server contains the installation image needed to install systems from the network. You must create an install server to install the Solaris software on a system from the network. You do not always need to set up a separate boot server.

If you are using DHCP to set installation parameters or your install server and client are on the same subnet, you do not need a separate boot server.
If your install server and your client are not on the same subnet and you are not using DHCP, you must create separate boot servers for each subnet. You could create an install server for each subnet; however, install servers require more disk space.

x86: To Create an x86 Install Server With x86 CD Media

This procedure creates an x86 install server with x86 CD media.

If you want to create a SPARC network installation image, see SPARC: To Create a SPARC Install Server With SPARC or x86 CD Media.

Note - This procedure assumes that the system is running the Volume Manager. If you are not using the Volume Manager to manage media, refer to System Administration Guide: Devices and File Systems.

On the system that is to become the install server, become superuser or assume an equivalent role.
The system must include a CD-ROM drive and be part of the site's network and naming service. If you use a naming service, the system must already be in a naming service, such as NIS, NIS+, DNS, or LDAP. If you do not use a naming service, you must distribute information about this system by following your site's policies.
Insert the Solaris Software - 1 CD in the system's drive.
Create a directory for the CD image.
```
# mkdir -p install_dir_path
```
install_dir_path

Specifies the directory where the CD image is to be copied
Change to the Tools directory on the mounted disc.
```
# cd /cdrom/cdrom0/Solaris_11/Tools
```
In the previous example, cdrom0 is the path to the drive that contains the Solaris OS CD media.
Copy the image in the drive to the install server's hard disk.
```
# ./setup_install_server install_dir_path
```
install_dir_path

Specifies the directory where the CD image is to be copied

Note - The setup_install_server command indicates whether you have enough disk space available for the Solaris Software disc images. To determine available disk space, use the df -kl command.
Decide if you need to make the install server available for mounting.
- If the install server is on the same subnet as the system to be installed or you are using DHCP, you do not need to create a boot server. Proceed to Step 7.
- If the install server is not on the same subnet as the system to be installed and you are not using DHCP, complete the following steps.
  1. Verify that the path to the install server's image is shared appropriately.
    Use either the share command or the sharemgr utility to complete the verification.
```
# share | grep install_dir_path
```
```
# # sharemgr show -v | grep install_dir_path
```
    Note - Starting with the 5/07 Developer release, the sharemgr utility introduces the concept of share groups. See sharemgr Command in System Administration Guide: Network Services.
    
    install_dir_path
    
    Specifies the path to the installation image where the CD image was copied
    - If the path to the install server's directory is displayed and anon=0 is displayed in the options, proceed to Step 7.
    - If the path to the install server's directory is not displayed or you do not have anon=0 in the options, continue.
  2. Make the install server available to the boot server by using either the share command or the sharemgr utility.
    - Using the share command, add this entry to the /etc/dfs/dfstab file.
```
share -F nfs -o ro,anon=0 -d "install server directory" install_dir_path
```
    - Using the sharemgr utility, enter the following commands:
      # sharemgr add-share -d “install server directory” -s install_dir_path default
      # sharemgr set -P nfs -S sys -p ro="*" -s install_dir_path default
      # sharemgr set -P nfs -p anon=0 -s install_dir_path default
  3. Verify that the nfsd daemon is running.
    - If the install server is running the current Solaris release, or compatible version, type the following command.
```
# svcs -l svc:/network/nfs/server:default
```
      If the nfsd daemon is online, continue to Step d. If the nfsd daemon is not online, start it.
```
# svcadm enable svc:/network/nfs/server
```
    - If the install server is running the Solaris 9 OS, or compatible version, type the following command.
```
# ps -ef | grep nfsd
```
      If the nfsd daemon is running, continue to Step d. If the nfsd daemon is not running, start it.
```
# /etc/init.d/nfs.server start
```
  4. If you are using the share command instead of the sharemgr utility, share the install server.
```
# shareall
```
Change directories to root (/).
```
# cd /
```
Eject the Solaris Software - 1 CD.
Insert the Solaris Software - 2 CD in the system's CD-ROM drive.
Change to the Tools directory on the mounted CD:
```
# cd /cdrom/cdrom0/Solaris_11/Tools
```
Copy the CD in the CD-ROM drive to the install server's hard disk.
```
# ./add_to_install_server install_dir_path
```
install_dir_path

Specifies the directory where the CD image is to be copied
Change directories to root (/).
```
# cd /
```
Eject the Solaris Software - 2 CD.
Repeat Step 9 through Step 13 for each Solaris Software CD that you want to install.
Insert the first Solaris Languages CD in the system's CD-ROM drive.
Change to the Tools directory on the mounted CD:
```
# cd /cdrom/cdrom0/Solaris_11/Tools
```
Copy the CD in the CD-ROM drive to the install server's hard disk.
```
# ./add_to_install_server install_dir_path
```
install_dir_path

Specifies the directory where the CD image is to be copied
Eject CD.
Repeat Steps 15–18 for each Solaris Languages CD.
Change directories to root (/).
```
# cd /
```
Patch the files that are located in the miniroot on the net install image that was created by setup_install_server. Patching a file might be necessary if a boot image has problems. Follow these substeps to patch an x86 network installation miniroot.
1. If the installation server is not running the current Solaris release for x86 systems, log in as superuser to another system on the network that is running the current Solaris release for x86 systems.
  To patch a current Solaris release for x86 miniroot, your system must be running the current Solaris release for x86 systems.
2. Change to the Tools directory of the installation image you created in Step 5.
```
# cd install-server-path/install-dir-path/Solaris_11/Tools
```
  install-server-path
  
  Specifies the path to the install server system on your network, for example, /net/installserver-1.
3. Create a new installation image, and place that image on the system that is running the current Solaris release for x86 systems.
```
# ./setup_install_server remote_install_dir_path
```
  remote_install_dir_path
  
  Specifies the path on the current Solaris release for x86 systems in which to create the new installation image.
  
  This command creates a new installation image on the current Solaris release for x86 systems. In order to patch this image, you must temporarily place this image on a system that is running the current Solaris release for x86 systems.
4. Unpack the network installation boot archive.
```
# /boot/solaris/bin/root_archive unpackmedia install_dir_path \ destination_dir
```
  install_dir_path
  
  Specifies the path to the x86 network installation image.
  
  destination_dir
  
  Specifies the path to the directory to contain the unpacked boot archive.
5. Patch the unpacked boot archive.
```
# patchadd -C destination_dir path-to-patch/patch-id
```
  path-to-patch
  
  Specifies the path to the patch that you want to add, for example, /var/sadm/spool.
  
  patch-id
  
  Specifies the patch ID that you want to apply.
  You can specify multiple patches with the patchadd -M option. For more information, see patchadd(1M).
  
  Caution - Don't use the patchadd -C command unless you have read the Patch README instructions or have contacted your local Sun support office.
6. Pack the x86 boot archive.
```
# /boot/solaris/bin/root_archive packmedia destination_dir \ install_dir_path
```
7. If necessary, copy the patched miniroot to the installation image on the install server.
  If you patched the miniroot on a remote current Solaris release for x86 systems, you must copy the patched miniroot to the install server.
```
# cp remote_install_dir_path/boot/x86.miniroot \ install-server-path/install_dir_path/boot/x86.miniroot
```
Decide if you need to create a boot server.
- If you are using DHCP or the install server is on the same subnet as the system to be installed, you do not need to create a boot server. Proceed to Adding Systems to Be Installed From the Network With a CD Image.
- If you are not using DHCP and the install server and the client are on a different subnet, you must create a boot server. Proceed to Creating a Boot Server on a Subnet With a CD Image.

Example 6-3 x86: Creating an x86 Install Server With x86 CD Media

The following examples illustrate how to create an install server by copying the following CDs to the install server's /export/home/cdx86 directory. This example assumes that the install server is running the current Solaris release.

Solaris Software for x86 Platforms CDs
Solaris Languages for x86 Platforms CDs

Insert the Solaris Software for x86 Platforms - 1 CD in the system's CD-ROM drive.

Set up an install server.

# mkdir -p /export/home/dvdx86
# cd /cdrom/cdrom0/Solaris_11/Tools
# ./setup_install_server /export/home/cdx86

If you have a separate boot server, add these steps.
1. Make the install server available to the boot server by using either the share command or the sharemgr utility.
  - Using the share command, add this entry to the /etc/dfs/dfstab file.
```
share -F nfs -o ro,anon=0 -d "install server directory" /export/home/cdx86
```
  - Using the sharemgr utility, enter the following commands:
    # sharemgr add-share -d “install server directory” -s /export/home/cdx86 default
    # sharemgr set -P nfs -S sys -p ro="*" -s /export/home/cdx86 default
    # sharemgr set -P nfs -p anon=0 -s /export/home/cdx86 default
2. Check if the nfsd daemon is online. If the nfsd daemon is not online, start it and share it.
  If you are using sharemgr utility, omit shareall.
```
# svcs -l svc:/network/nfs/server:default
# svcadm enable svc:/network/nfs/server
# shareall 
```
3. Continue with the following steps.
If you do not need a boot server or have completed the steps for a separate boot server, continue with the following steps.

# cd /

Eject the Solaris Software for x86 Platforms - 1 CD. Insert the Solaris Software for x86 Platforms - 2 CD in the CD-ROM drive.

# cd /cdrom/cdrom0/Solaris_11/Tools
# ./add_to_install_server /export/home/cdx86
# cd /

Repeat the previous commands for each Solaris Software CD that you want to install.

Insert the first Solaris Languages for x86 Platforms CD in the CD-ROM drive.

# cd /cdrom/cdrom0/Solaris_11/Tools
# ./add_to_install_server /export/home/cdx86

Eject CD.

Repeat previous commands for each Solaris Languages for x86 Platforms CD.

More Information

Continuing the Installation

After you set up the install server, you must add the client as an installation client. For information about how to add client systems to install over the network, see Adding Systems to Be Installed From the Network With a CD Image.

If you are not using DHCP, and your client system is on a different subnet than your install server, you must create a boot server. For more information, see Creating a Boot Server on a Subnet With a CD Image.
