The most imp ortant part of y

t Ignition" disk. Y
ou
can protect your data and system from loss, using the general procedures giv
en
in this chapter. (For detailed pro cedures, see
Instal ling and Updating HP-UX

Make sure you create and maintain a backup HP-UX kernel (
/SYSBCKUP
)
on your disk from whichyou can bo ot in an emergency
.A
/SYSBCKUP

Creating a Recovery System
A \recovery system" is a sp ecial tap e con
taining a subset of the HP-UX
operating system. In the event of an op erating system failure that prev
ents you
from b o oting or logging into HP-UX, you can bo ot from the reco
very system
tap e and use the tools on the tap e to repair the le system on y
our disk. A
recovery system is created by using commands rather than by using SAM.
You can also restore your system from a system CD ROM that you can
purchase from your HP sales representative.
You should make a recovery tap e using
mkrs
at the follo wing times:
Immediately after you set up your new workstation.
