Creating Disk Groups

Detailed Steps

To create a disk group, follow these steps:

1. Open DCNM-SAN Web Client. Log in with the user name and password.

For login information, refer to the Cisco DCNM-SAN Fundamentals Guide.

2. In the DCNM-SAN Web Client, click the SME tab.

3. Create a disk-capable cluster. For more information, see “Creating a SME Cluster Using the SME Wizard”.

4. Select Disk Groups. Click Add.

The disks in an SME cluster can be grouped functionally into disk groups.

Note The Disk Group tab is displayed only when a disk-capable cluster is created.

5. Enter a name for the disk group. Click Next.

Note The disk group wizard allows you to create an empty disk group when you click Finish. If you click Finish, an empty disk group is created that can be used for pre-provisioning. The series of filters allows you to add the disks to a disk group from the Fabric > VSAN > Zones > Select Disks menu option.

6. Select specific VSANs for the disk group. Click Next.

VSANs are displayed for single as well as dual fabrics. You can select the VSANs for each fabric that you would like to discover the path for.

7. Select specific zones for the disk group. Click Next.

8. Select the hosts for the disk group. You can select single or multiple hosts. Click Next.

9. Select the disk targets for the disk group. You can select single or multiple disk targets. Click Next.

10. Select the disks to create the disk group. Click Next.

Caution Failure to add all of the paths from the host to storage can result in data loss or data corruption.

The select disk path screen shows the Disk Name that you can modify, Vendor ID (VID), Product ID (PID), Device ID (DID), and number of paths for the disk. Along with this information when you click on the zoom icon, you can see the Initiator PWWN, Target PWWN, and the number of LUNs for the corresponding disk.

11. Verify the information shown on the confirmation screen. Click Confirm to save and activate the changes.

12. View the disk group that is successfully added to a cluster.
