Use this procedure to replace an existing quorum device with another quorum device. You can replace a quorum device with a similar device type, such as replacing a NAS device with another NAS device, or you can replace the device with a dissimilar device, such as replacing a NAS device with a shared disk.
Configure a new quorum device.
You need to first add a new quorum device to the configuration to take the place of the old device. See Adding a Quorum Device to add a new quorum device to the cluster.
Remove the device that you are replacing as a quorum device.
See How to Remove a Quorum Device to remove the old quorum device from the configuration.
If the quorum device is a failed disk, replace the disk.
