HP StorageWorks Scalable File Share - Manual (Page 59)

6 Licensing
A valid license is required for normal operation of HP SFS G3.2-0. HP SFS G3.2-0 systems are
preconfigured with the correct license file at the factory, making licensing transparent for most
HP SFS G3.2-0 users. No further action is necessary if your system is preconfigured with a license,
or if you have an installed system. However, adding a license to an existing system is required
when upgrading a G3.0-0 server to G3.2-0.
NOTE: HP SFS is licensed by storage capacity. When adding a license for an existing system,
ensure that the storage capacity of the system is reflected in the licensing agreement.
6.1 Obtaining a New License
For details on how to get a new license, see the License-To-Use letters that were included with
the HP SFS server DVD. There will be one License-To-Use letter for each HP SFS G3.2-0 license
that you purchased. An overview of the redemption process is as follows:
1. Run the sfslmid command on the MGS and the MDS to obtain the licensing ID numbers.
2. Use these ID numbers to complete a form on the HP website.
6.2 Installing a New License
The license file must be installed on the MGS and the MDS of the HP SFS server. The licensing
daemons must then be restarted, as follows:
1. Stop Heartbeat on the MGS and the MDS.
2. Copy the license file into /var/flexlm/license.lic on the MGS and the MDS.
3. Run the following command on the MGS and the MDS:
# service sfslmd restart
4. Restart Heartbeat. This restarts Lustre. The cluster status follows:
hpcsfsd1:root> crm_mon -1

5. To verify current license validity, run the following command on the MGS and the MDS as
root:
# sfslma check
SFS License Check succeeded. SFSOSTCAP granted for 1 units.
6.3 Checking for a Valid License
The Lustre MGS does not start in the absence of a valid license. This prevents any Lustre client
from connecting to the HP SFS server. The following event is recorded in the MGS node message
log when there is no valid license:
