Removing MDisks from an MDisk group

You can remove managed disks (MDisks) from an MDisk group.

This task assumes that you have already launched the SAN Volume Controller Console.

Solid-state drives (SSDs) that are located in SAN Volume Controller 2145-CF8 nodes are presented to the cluster as MDisks. To determine whether the selected MDisk is an SSD, click the link on the MDisk name to display the Viewing MDisk Details panel. If the selected MDisk is an SSD that is located on a SAN Volume Controller 2145-CF8 node, the Viewing MDisk Details panel displays values for the Node ID, Node Name, and Node Location attributes. Alternatively, you can select Work with Managed Disks > Disk Controller Systems from the portfolio. On the Viewing Disk Controller panel, you can match the MDisk to the disk controller system that has the following values for these attributes.
