The software licensing used by CXFS is based on the FLEXlm product from Macrovision Corporation. For all nodes in the cluster, a FLEXlm license is required to use CXFS. Perform the procedures in this chapter to satisfy this requirement.
XVM provides a mirroring feature. If you want to access a mirrored volume from a given node in the cluster, you must install a FLEXlm mirroring license on that node. Only those nodes that will access the mirrored volume must be licensed. For information about purchasing this license, see your SGI sales representative.
This section discusses the following:
When you order CXFS, you will receive an entitlement ID. You must submit the system host ID, host name, and entitlement ID when requesting your permanent CXFS license. The method used to obtain this information is platform-specific.
To obtain the host identifier and hostname of the system on which you will run CXFS, see the information in the CXFS release notes.
For SGI Altix systems, you must obtain the host identifier, hostname, serial number, and CPU count of the system on which you will run CXFS. Execute the following commands:
cat /proc/sgi_sn/system_serial_number /sbin/ifconfig eth0 /bin/hostname hinv -c processor |
The system serial number allows SGI to generate multiple host ID keys for Altix partitioning.
The host identifier is the value for the HWaddr field, minus the colons.
For example:
[root@linux64 root]# cat /proc/sgi_sn/system_serial_number
N0000002
[root@linux64 root]# /bin/hostname
cxfslinux
[root@linux64 root]# /sbin/ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:E0:81:24:77:D1

In this case, the host identifier is 00E0812477D1 and there are 4 processors.
When you are asked for the license manager host identifier, provide this information. You must have a separate license for each host on which CXFS is installed.
Along with your entitlement number, you will receive a URL to a key generation page. To obtain your permanent CXFS and XVM licenses, follow the instructions on the key generation page. After the required information is provided, a key will be generated and displayed on the webpage along with installation instructions.
Use the cxfslicense command with the -d option to verify that the FLEXlm licenses have been installed properly.
For example, if the CXFS license is properly installed on an SGI Altix 3000 system, you will see the following:
[root@linux64 root]# /usr/cluster/bin/cxfslicense -d XVM_STD_IPF license granted. XVM_PLEX_IPF license granted. CXFS_IPF license |
If you do not have the CXFS license properly installed, you will see an error message. For example, if the license is not installed on a client-only node, you will see the following on the console and in the cxfs client logs when trying to run CXFS:
May 12 14:40:17 cxfs_client: cis_main FATAL: cxfs_client failed the CXFS license check. Use the cxfslicense command to diagnose the license problem. May 12 14:40:17 cxfs_client: FATAL: aborting on fatal error |
On an administration node, the error will appear in the clconfd log.
