A LUN exists in the VNX storage group that does not exist in the LUN list. This ERROR was introduced in 4.4 (internal bug 117702). The customer may have configuration issues in their environment at versions below 4.4, but will see this error when upgrading to 4.4. 

Resolution

Workaround:1] The customer needs to remove the LUN from the storage group that was incorrectly added. 2] Followed by a reboot of the site control candidate RPAs.
