Suggestions for Loading from a Non-AIX Host

In this procedure, you must request the 7318 BIOS console to store the load host name, the boot file name and path, and the 7318's IP address in the 7318's nonvolatile RAM. This information enables the 7318 to load its operating image and configuration file. The BIOS console is a command interpreting shell for setting and changing 7318 NVRAM parameters.

The 7318 supports the BOOTP protocol. Refer to "Enabling a 7318 to Load from a Host" for a discussion of the required parameters that the bootptab file should contain. Refer to the non-AIX host bootpd daemon and bootptab file documentation for differences in implementation or file formats.

When enabling the tftpd daemon, note whether you are implementing insecure or secure TFTP. If you enable secure, your 7318 files (load image and configuration file) will need to reside in the directory specified as secure. Otherwise the load will fail.

Prerequisites

1. You must have root user authority.
2. You must be in password privilege mode on the 7318.
3. You must enable the tftpd daemon on the non-AIX host.

Procedure

1. Copy the contents of the /usr/lib/cns directory to a diskette by typing:

   tar cvf /dev/Device /usr/lib/cns

2. On the non-AIX host, extract the entire contents of the diskette by typing:

   tar xvf /dev/Device

   This will create a directory called /usr/lib/cns and extract files into that directory.
3. On the 7318, request the BIOS console. Refer to "7318 BIOS" for information on how to issue a BIOS console request. At the BIOS console prompt, set the host1 field by typing:

   set host1 XXX.XXX.XXX.XXX

   where the XXX.XXX.XXX.XXX parameter is the IP address of the non-AIX host. This tells the 7318 BIOS to skip the bootp query when it powers up and jump immediately to a TFTP download from the host specified by the IP address.
4. Run the loadi command to specify the load image and its path, for example:

   set loadi /usr/lib/cns/cns-s20)

5. Run the following commands on the BIOS console to set the parameters for this configuration, for example:

   set protocol=2
   set inet=66.55.44.33
   set netmask=255.255.255.128

6. Enter:

   save

   to store the host1, loadi, and inet fields in the NVRAM.
7. Enter:

   load

   to initiate downloading. The 7318 will immediately begin a TFTP load of the specified load image from the specified load host.
