UNKNOWN host type or model
Viewing UNKNOWN host type or model
Run lshosts. A model or type UNKNOWN indicates the host is down or the LIM on
the host is down. You need to take immediate action. For example:
%
lshosts
HOST_NAME type model cpuf ncpus maxmem maxswp server RESOURCES
hostA UNKNOWN Ultra2 20.2 2 256M 710M Yes ()
Fixing UNKNOWN
host type or
model
1
Start the host.
2
Run lsadmin limstartup to start up the LIMs on the host. For example:
#
lsadmin limstartup hostA
Starting up LIM on <hostA> .... done
You can specify more than one host name to start up LIM on multiple hosts. If you
do not specify a host name, LIM is started up on the host from which the command
is submitted.
On UNIX, in order to start up LIM remotely, you must be root or listed in
lsf.sudoers and be able to run the rsh command across all hosts without
entering a password. See “Prerequisites” on page 86 for more details.

Wait a few seconds, then run lshosts again. You should now be able to see a
specific model or type for the host or DEFAULT. If you see DEFAULT, you can
leave it as is. When automatic detection of host type or model fails, the type or
model is set to DEFAULT. LSF will work on the host. A DEFAULT model may be
inefficient because of incorrect CPU factors. A DEFAULT type may cause binary
incompatibility because a job from a DEFAULT host type can be migrated to
another.
DEFAULT host type or model
Viewing DEFAULT
host type or
model
Run lshosts. If Model or Type are displayed as DEFAULT when you use lshosts
and automatic host model and type detection is enabled, you can leave it as is or change
it. For example:
%
lshosts
HOST_NAME type model cpuf ncpus maxmem maxswp server RESOURCE
S
hostA DEFAULT DEFAULT 1 2 256M 710M Yes ()
If model is DEFAULT, LSF will work correctly but the host will have a CPU factor of
1, which may not make efficient use of the host model.
If type is DEFAULT, there may be binary incompatibility. For example, there are 2 hosts,
one is Solaris, the other is HP. If both hosts are set to type DEFAULT, it means jobs
running on the Solaris host can be migrated to the HP host and vice-versa.
Fixing DEFAULT
host type
1
Run lim -t on the host whose type is DEFAULT:
%
lim -t
