Adding MDisks to MDisk groups

You can add managed disks (MDisks) to an MDisk group from the Adding Managed Disks to Managed Disk Group panel.

If you are using a SAN Volume Controller solid-state drive (SSD) managed disk, ensure that you are familiar with the SSD configuration rules.

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.

Table 1. Disk controller attributes for SSDs
Attribute	SSD value
Vendor ID	IBM
Product ID Low	2145
Product ID High	Internal

Note: The first time that you add a new solid-state drive (SSD) to an MDisk group, the SSD is automatically formatted and set to a block size of 512 bytes.

Perform the following steps to add MDisks to an MDisk group:

Click Work with Managed Disks > Managed Disk Groups in the portfolio. The Viewing Managed Disk Groups panel is displayed.
Select the MDisk group to add MDisks to and select Add MDisks from the list. Click Go. The Adding Managed Disks to Managed Disk Group panel is displayed.
Select the MDisks to add and click OK.
