Booting Your Workstation - HP Model 745 - VME Workstation Handbook

Booting Your Workstation

Usually, you start your workstation by turning it on and waiting for the operating 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 system 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 boot-
able operating system, follow the directions in "Accessing the Boot Console Interface"
earlier in this chapter, and then type the following at the prompt:
Main Menu: Enter command >
where device is the hardware path to the device, specified in Mnemonic Style Nota-
tion. 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.
• The Initial System Loader (ISL) is the program that actually controls the loading of the
operating system. By interacting with ISL, you can choose to load an alternate version
of the HP-UX operating system. If you wish to interact with the ISL before booting
your workstation, follow the directions in "Accessing the Boot Console Interface" ear-
lier in this chapter, and then type the following at the prompt:
Main Menu: Enter command > boot device
You are prompted:
Interact with ISL (Y,N,Q)>
