If a node pool consists of C72 nodes, the node pool can contain 2 to 10 nodes. - After deployment, nodes in a node pool cannot be modified. - If you want to modify a node, you must delete the node from its original pool first, and then add the node to a new pool.

Method used to change owning controllers of LUNs
1. For a RAID group consisting of SATA disks, it is recommended that LUNs in the same RAID group be configured with the same owning controller. For a RAID group consisting of other types of disks, it is recommended that LUNs in the same RAID group be allocated to different owning controllers. 2. Go to the Modify LUN dialog box. In the ISM navigation tree, choose All Devices > SN_XX > Storage Resources > LUN. (SN_XX is the name of the target storage system.) In the right function pane, select the LUN you want to modify. Click Modify. The Modify LUN dialog box is displayed. Modify the basic and advanced attributes of the LUN.
