Booting

The Jaz disk can be used to boot the workstation and run the installation scripts which copy the ISS software onto the internal system disks. To boot the Jaz disk, the workstation must be at the EEPROM boot prompt:

ok 

The workstation should already have an alias for the Jaz boot device, so this command can be used to boot the system:

ok boot jaz -r

The option -r causes the boot sequence to reconfigure the device file entries according to the devices on the workstation being booted, since those devices may not necessarily be the same as on the system from which the distribution disk was created.

If the jaz device alias is not recognized, the Jaz disk will need to be referenced by its full device path name, similar to this:

See Creating the NVRAM Alias for instructions on creating the jaz device alias.

The workstation should boot and run on the Jaz disk, meaning the internal system disks will not be used at all. While running from the Jaz disk, the workstation will use whatever configuration was last set on the Jaz disk, including the host name. The configuration changes once the system is installed, reconfigured, and rebooted.

If the workstation being installed is connected to a network on which its network address is already being used, problems will ensue. If unsure, it is safe to disconnect the ISS workstation from the network while running it from a Jaz distribution disk. The workstation can be reconnected after the installation once it reboots with its correct configuration and new host name.
