Add.
3. When prompted, reboot the Windows host.
4. After rebooting, launch Disk Management again and verify that only one instance of each drive is
displayed.
5. Initialize each disk and bring it online.
6. Format each volume.
a. For the Quorum Disk, assign a drive letter of your choice (Q in this example) and assign an
intuitive volume label such as QuorumDisk.
b. For the cluster volume, do not assign a drive letter or path when formatting the volume. Assign an
intuitive volume label such as CSV01.
7. Now that MPIO is enabled on the Windows host servers, follow the recommendations in the Dell EMC
SC Series Microsoft Multi-path I/O Best Practices Guide to configure optimal MPIO settings.
Note: This a critical step to ensure that host server MPIO timeout thresholds are adjusted to tolerate paused
I/O (up to 60 seconds) which is typical during planned maintenance such as staggered controller upgrades.
