Use the EVMSGUI (or EVMSN or EVMS) tool to check the names ofthe devices if needed, and only use the base (leaf) names (such as sdb or mpathd) with the -doption.For example, you might enter something similar to the following:sbdutil -c -n mycluster1 -d sdb -d sdc2 Modify the Cluster object in eDirectory to enable its NCS: Shared Disk Flag attribute.2a In a Web browser, open iManager, then log in to the Novell eDirectory tree that containsthe cluster you want to manage.IMPORTANT: Log in as an administrator user who has sufficient rights in eDirectory todelete and modify eDirectory objects.2b Click eDirectory Administration, then click Modify Object.2c Browse to locate and select the Cluster object of the cluster you want to manage, thenclick OK.2d Under Valued Attributes, select the NCS: Shared Disk Flag, then click Edit.2e Select (enable) the NCS: Shared Disk Flag check box, then click OK.2f Click Apply to save changes.3 Reboot all cluster nodes.
