Replace a membership partition To replace a membership partition, use this command: mx config mp set Specify the UUIDs for the new membership partition and for the two existing membership partitions that will be retained. The mprepair utility The /opt/hpcfs/lib/mprepair utility is invoked from the command line. IMPORTANT: HP Scalable NAS cannot be running when you use mprepair. To stop the cluster, issue the command # /etc/init.d/pmxs stop on each node. Membership partition file Each server in the cluster has a membership partition file, which is called the "local MP list." This file specifies the locations of the membership partitions. Each membership partition also has its own MP list. Because the membership partitions control access to the SAN, it is important that each server in the cluster have the same view of where the partitions are located. However, it is possible for these views to get out of sync if changes to the membership partition configuration are made when all servers are not accessible. Therefore, before a server can negotiate for control of the SAN, it must have a local MP list that matches the membership lists stored on each of the membership partitions, and each membership partition must be in the Active state. The mprepair utility can be used to repair any problems if a failure causes servers to have inconsistent views of the membership partitions. View membership partitions and their status To view the current membership partitions, type the following command: mprepair --get_current_mps HP Scalable NAS File Serving Software administration guide 365
