Unconfiguring Clustering

1. Select the storage controller that will be reset to its factory configuration. Note that if replacing a failed storage controller, you can skip to step 3, provided that the failed storage controller will not be returned to service at your site.
2. From the system console of the storage controller that will be reset to its factory configuration, perform a factory reset.
3. The storage controller will reset, and its peer will begin takeover normally. NOTE: Prior to allowing the factory-reset storage controller to begin booting (i.e., prior to progressing beyond the boot menu), power it off and wait for its peer to complete takeover.
4. Detach the cluster interconnect cables (see above) and detach the powered-off storage controller from the cluster's external storage enclosures.
5. On the remaining storage controller, click the Unconfig button on the Configuration -> Clustering screen. All resources will become assigned to that storage controller, and the storage controller will no longer be a member of any cluster.
6. The detached storage controller, if any, can now be attached to its own storage, powered on, and configured normally. If you are replacing a failed storage controller, attach the replacement to the remaining storage controller and storage and begin the cluster setup task described above.

   Note -  If your cluster had 2 or more pools, ownership of all pools will be assigned to the remaining storage controller after unconfiguration. In software versions prior to 2010.Q1.0.0, this was not a supported configuration; if you are running an older software version, you must do one of: destroy one or both pools, attach a replacement storage controller, perform the cluster setup task described above, and reassign ownership of one of the pools to the replacement storage controller, or upgrade to 2010.Q1.0.0 or a later software release which contains support for multiple pools per storage controller.
