How to Remove Unverified System in VNX Domain

VNX Storage arrays can be added to a domain for centralization logging and management for multiple storage arrays. Also Unisphere Central can be added to a VNX domain.

Sometimes, storage administrator makes mistake about adding or removing VNX storage arrays from VNX domain. As an example, administrator has to remove a VNX for send to repairing but forget removing storage array from domain. Another example, when there is multiple domains with multiple range of IP addresses, may be administrator add array to domain wrongly and after that, change IP and add to another domain.

In these situations, domains will contain some systems as unverified system, the unverified systems should verify again and otherwise should be removed.
