Naming and Formatting Drives on the Shared Storage System
When the LUNs have completed the binding process, assign drive letters to the LUNs and then format the drives as NTFS drives. Format the
drives and assign volume labels from the first cluster node. When completed, the remaining nodes will see the file systems and volume labels.
NOTICE: Accessing the hard drives from multiple cluster nodes may corrupt the file system.
Assigning LUNs to Hosts
If you have Access Control enabled in Navisphere Manager, you must create storage groups and assign LUNs to the proper host systems.
Assigning Drive Letters
NOTICE: If the disk letters are manually assigned from the remaining node, the shared disks are simultaneously accessible from both
nodes. To ensure file system integrity and prevent possible data loss before you install the MSCS software, prevent any I/O activity to
the shared drives by performing this procedure on one node at a time, and ensure that all other nodes are shut down.
The number of drive letters required by individual servers in a cluster may vary. Dell recommends that the shared drives be named in reverse
alphabetical order beginning with the letter z.
To assign drive letters and format the disks on the shared storage system:
1. With the other node shut down, open Disk Management on node 1.
2. Allow Windows to enter a signature on all new physical or logical drives.
NOTE: Do not create dynamic disks on your hard drives.
3. Locate the icon for the first unnamed, unformatted drive on the shared storage system.
4. Right-click the icon and select Create from the submenu.
If the unformatted drives are not visible, verify the following:
The HBA driver is installed.
The storage system is properly cabled to the servers.
The LUNs and hosts are assigned through a storage group (if Access Control is enabled).
5. In the dialog box, create a partition the size of the entire drive (the default) and then click OK.
NOTE: The MSCS software allows only one node to access a logical drive at a time. If a logical drive is partitioned into multiple
disks, only one node is able to access all the partitions for that logical drive. If each node needs to access a separate disk, two or
more logical drives must be present in the storage system.
6. Click Yes to confirm the partition.
7. With the mouse pointer on the same icon, right-click and select Change Drive Letter and Path from the submenu.
8. Assign a drive letter to an NTFS volume.
To assign a drive letter to an NTFS volume:
a. Click Edit and select the letter you want to assign to the drive (for example, z).
b. Click OK.
9. Click Yes to confirm the changes.
