sphps01:
define = define an object
change = change an object
′
s attributes
remove = remove an object
allocate = allocate a resource for use
deallocate = deallocate a resource
diag
= enable a machine to boot a diagnostic image
cust = perform software customization
bos_inst = perform a BOS installation
maint = perform software maintenance
reset = reset an object

s NIM state
lslpp = list LPP information about an object
fix_query = perform queries on installed fixes
check = check the status of a NIM object
reboot = reboot specified machines
This
-O
option of the
lsnim
command is very useful in determining the set of
operations that can be performed on a specific object (the object sphps01 of type
machine, in this case).
define This operation creates a new NIM machine object. In the RS/6000
SP environment, it is called by
setup_server
for all nodes which are
known to the SDR.
# nim -o define -t standalone -a if1=
′
spnet speth02 10005aa88123
′
\
-a cable_type1=dix newhost
This operation creates the standalone NIM machine object newhost.
The NIM Network object
spnet must exist at this time. Several
checks are made; for instance, whether the IP address for
hostname
speth02 is reachable from the net spnet. Furthermore,
the attribute cable_type1 is a required for Ethernet network objects.
There are other optional attributes for machine objects:
iplrom_emu
,
cpuid
,
comments
,
ring_speed
,
cable_type
, and
platform
.
The script setup_server uses the attributes
platform
and
cpuid
in
addition to the given example.
change This operation changes the values of attributes.
# nim -o change -a cable_type1=bnc newhost
or
# nim -o change -a comments=
″
This is a comment...
″
newhost
To remove an optional attribute, just let the value for the attribute
void while changing the object.
# nim -o change -a comments= newhost
remove This operation removes a NIM machine object. Removing machine
objects is successful in case no resources are allocated to that
machine object and its
Cstate
is
Ready for a NIM operation
. This
state can be enforced by resetting the object:
# nim -o remove newhost
The script setup_server removes and redefines machine objects, for
instance, in case some of the node-specific information like the
hardware address of the SP Ethernet adapter changes. This
