Use this task to pass the ownership of your user managed GPFS™ cluster
to the IBM® DB2® pureScale® Feature.
Before you begin
- You need root access on each host to perform these steps.
- The DB2 pureScale Feature must
be installed on all hosts in the GPFS cluster
About this task
Only
GPFS clusters
created by
DB2 data
server products are registered in the
DB2 global
registry. Performing this task will take your existing user managed
GPFS cluster
and treated it as if it had been created by a
DB2 data
server product.
Procedure
To take over a user-managed GPFS cluster:
- Log on as root on any machine in your cluster.
- Run the db2cluster_prepare command
with the following parameters:
db2dir/instance/db2cluster_prepare -cfs_takeover
- Check the error return code using the echo $? command.
If there are errors, resolve the errors and rerun the command as specified
in Step 2.
- To verify that you've properly added the record, run the
following command:
db2dir/bin/db2greg -dump
The
following sample output should be returned: V,GPFS_CLUSTER,NAME,db2cluster_20111117140104.torolab.ibm.com,-,DB2_MANAGED
What to do next
You can now proceed with the installation of the
DB2 pureScale Feature.
