SPARC: Installing With WAN Boot (Tasks)

This chapter describes how to perform a WAN boot installation on a SPARC based client. For information about how to prepare for a WAN boot installation, see Chapter 43, Preparing to Install With WAN Boot (Tasks).

This chapter describes the following tasks.

Task Map: Installing a Client With WAN Boot

The following table lists the tasks you need to perform to install a client over a WAN.

Table 44-1 Task Map: Performing a WAN Boot Installation

Task

Description

For Instructions

Prepare the network for a WAN boot installation.

Set up the servers and files that are required to perform a WAN boot installation.

Chapter 43, Preparing to Install With WAN Boot (Tasks) 

Verify that the client system supports WAN boot.

Check the client OBP for boot argument support of WAN boot.

Checking the Client OBP for WAN Boot Support 

Verify that the net device alias is set correctly in the client OBP.

Use the devalias command to verify that the net device alias is set to the primary network interface.

Checking the net Device Alias in the Client OBP 

Provide keys to the client

Provide keys to the client by setting OBP variables or entering key values during the installation.

This task is required for secure installation configurations. For insecure installations that check data integrity, complete this task to provide the HMAC SHA1 hashing key to the client.

Installing Keys on the Client 

Install the client over a wide area network.

Choose the appropriate method to install your client.

Preparing the Client for a WAN Boot Installation

Before you install the client system, prepare the client by performing the following tasks.

Checking the Client OBP for WAN Boot Support

To perform a hands-off WAN boot installation, the client OpenBoot PROM (OBP) must support WAN boot. The following procedure describes how to determine if the client OBP supports WAN boot.

ProcedureTo Check the Client OBP for WAN Boot Support

  1. Become superuser or assume an equivalent role.

    Roles contain authorizations and privileged commands. For more information about roles, see "Configuring RBAC (Task Map)" in System Administration Guide: Security Services.

  2. Check the OBP configuration variables for WAN boot support.

    # eeprom | grep network-boot-arguments

    • If the variable network-boot-arguments is displayed, or if the previous command returns the output network-boot-arguments: data not available, the OBP supports WAN boot installations. You do not need to update the OBP before you perform your WAN boot installation.

    • If the previous command does not return any output, the OBP does not support WAN boot installations. You must perform one of the following tasks.

      • Update the client OBP. See your system documentation for information about how to update the OBP.

      • Perform the WAN boot installation from the Solaris 9 Software CD in a local CD-ROM drive. For instructions about how to boot the client from a local CD-ROM drive, see Installing With Local CD Media.

Example 44-1 Verifying OBP Support for WAN Boot on the Client

The following command shows how to check the client OBP for WAN boot support.

# eeprom | grep network-boot-arguments
network-boot-arguments: data not available

In this example, the output network-boot-arguments: data not available indicates that the client OBP supports WAN boot.

Checking the net Device Alias in the Client OBP

To boot the client from the WAN with the boot net, the net device alias must be set to the client's primary network device. On most systems, this alias is already set correctly. However, if the alias is not set to the network device you want to use, you must change the alias..

Follow these steps to check the net device alias on the client.

ProcedureTo Check the net Device Alias

  1. Become superuser on the client.

  2. Bring the system to run level 0.

     # init 0

    The ok prompt is displayed.

  3. At the ok prompt, check device aliases that are set in the OBP.

    ok devalias

    The devalias command outputs information that is similar to the following example.

    screen                   /pci@1f,0/pci@1,1/SUNW,m64B@2
    net                      /pci@1f,0/pci@1,1/network@c,1
    net2                     /pci@1f,0/pci@1,1/network@5,1
    disk                     /pci@1f,0/pci@1/scsi@8/disk@0,0
    cdrom                    /pci@1f,0/pci@1,1/ide@d/cdrom@0,0:f
    keyboard                 /pci@1f,0/pci@1,1/ebus@1/su@14,3083f8
    mouse                    /pci@1f,0/pci@1,1/ebus@1/su@14,3062f8

    • If the net alias is set to the network device you wan to use during the installation, you do not need to reset the alias. Go to Installing Keys on the Client to continue your installation.

    • If the net alias is not set to the network device you want to use, you must reset the alias. Continue.

  4. Set the net device alias.

    Choose one of the following commands to set the net device alias.

    • To set the net device alias for this installation only, use the devalias command.

      ok devalias net device-path

      net device-path

      Assigns the device device-path to the net alias

    • To permanently set the net device alias, use the nvalias command.

      ok nvalias net device-path

      net device-path

      Assigns the device device-path to the net alias

Example 44-2 Checking and Resetting the net Device Alias

The following commands show how to check and reset the net device alias.

Check the device aliases.

ok devalias
screen                   /pci@1f,0/pci@1,1/SUNW,m64B@2
net                      /pci@1f,0/pci@1,1/network@c,1
net2                     /pci@1f,0/pci@1,1/network@5,1
disk                     /pci@1f,0/pci@1/scsi@8/disk@0,0
cdrom                    /pci@1f,0/pci@1,1/ide@d/cdrom@0,0:f
keyboard                 /pci@1f,0/pci@1,1/ebus@1/su@14,3083f8
mouse                    /pci@1f,0/pci@1,1/ebus@1/su@14,3062f8
