The Boot Console Interface
Booting Your Workstation
Booting Your Workstation
Usually, you start your workstation by turning it on and waiting for the oper-
ating system to boot automatically. However, you may not always want the
usual sequence to occur.
For example, you may want to start your workstation from an operating sys-
tem that is stored on a device that is different from your usual boot device. If
your normal operating system kernel or the disk on which it resides becomes
damaged or unusable, you may wish to boot from a different disk or perhaps
another type of device, such as a DDS-format tape drive.
Here are some situations and examples:
•
If you know which device you want to boot from, and you know that it
contains a bootable operating system, follow the directions in “Accessing
the Boot Console Interface” earlier in this chapter, and then type the fol-
lowing at the prompt:
Main Menu: Enter command >
boot
device
where
device
is the
hardware path
to the device, specified in Mnemonic Style
Notation. When prompted whether or not to interact with the ISL enter
n
for no.
For example, if you wish to boot an operating system that is stored on a DDS-
format tape in a drive that is located at ‘‘sescsi.1.0’’, follow the directions in
“Accessing the Boot Console Interface” earlier in this chapter, and then type the
following command at the prompt:
Main Menu: Enter command >
boot
sescsi.1.0
Interact with ISL (Y,N,Q)>
n
The operating system on the specified device is used to start your workstation.
