% lsadmin reconfig
% lsadmin restart on the master LIM
The license file is re-read and the changes accepted by LSF. At this point, the LSF
license has been updated. However, some products may also require installation or
upgrade of LSF software before you can use the new functionality.
Updating a license with INCREMENT lines
If you received one or more INCREMENT lines, update your license by adding the lines
to your existing license file.
1 Edit your license.dat file using a text editor like vi or emacs. See “Viewing
and editing the license file” on page 177.
2 Always append an INCREMENT line, do not overwrite or delete existing license lines
in the process.
❖ If this is the first increment, add the INCREMENT line for each product after the
FEATURE line for that product.
❖ If you already have an INCREMENT line for the product, add the second
INCREMENT line after the first, and so on.
3 Reconfigure LSF by using either of the following LSF commands:
% lsadmin reconfig
% lsadmin restart on the master LIM
The license file is re-read and the changes accepted by LSF.
Interoperation of LSF 4.x and LSF 5.x clusters
Read this if your license file is currently used by multiple LSF version 4.x clusters, and
you wish to upgrade some but not all of the clusters to LSF 5.x.
A permanent LSF license allows only one FEATURE line for each LSF product or
feature. If your license file is used by multiple LSF clusters, and you wish to upgrade just
one cluster, you have to upgrade the licenses all at once (for example, a 5.x FEATURE
line for
lsf_base replaces the 4.x FEATURE line for lsf_base).
Licenses for LSF 4.x are backwards-compatible, for example, a version 4.2 license can
also license clusters running LSF version 4.1 or 4.0. However, the LSF version 5.x
license is not fully compatible with LSF version 4.x. If you want to use one license file
to run both 4.x and 5.x clusters, the 4.x clusters require the
lsf_batch feature, which
is not included in the 5.x license.
To make your license work for both versions of LSF, edit the 5.x license file and append
your 4.x FEATURE line for
lsf_batch, and also any 4.x INCREMENT lines for
lsf_batch. These lsf_batch lines can be deleted after all your clusters have been
upgraded to LSF 5.x.
