Servicing the CPU 2-5
Another important environment variable, not shown in Table 2-1, because
it is not a default variable but may be defined by the customer, is a nick-
name. Should the customer want to have a default boot path for a cluster
and a different local one, a nickname variable may be used for that pur-
pose. Nicknames are set by a console command of the form
create -nv
old_disk dua0.0.0.4.0.
The
-nv
option indicates this nonvolatile environ-
ment variable will be stored in EEPROM. Once
old_disk
is so defined,
one can type
boot old_disk
at the console prompt. Once the environment
variable
old_disk
has been defined, it can be modified with the
set
com-
mand.
