Hi @Sue_8827 ,
The error code was '0x13c1' (the cluster IP address already in use).
After some research I found that this is a virtual IP that is set the same as cluster IP. Can I delete this?
Try not to do this. If you delete this IP address, the cluster will not find the corresponding IP address. It may be wrong in the case of static addresses. Of course, DHCP may also go wrong, it may find another duplicate address. Rather than delete operation that have a greater impact, I recommend modification operation.
You can right-click the cluster name->Properties->give it an unoccupied static IP and bring it online.
