EMC AX-150 Changing IP-addreses

Hello, Experts! I need to change ip addresses of SPA and SPB of my FC EMC AX-150 storage. As how I know, I need to un-initialize and initialize storage with Navisphere Server Utility to do this. But how will be my LUNs and FC-connections after this? It will be destroyed or it will be OK ?

For FC you don't have IPs, only WWNs. If you change the IPs of your SPs, nothing changes on FC-side. I have done this several times with our FC AX-4. Just change the IPs from inside Navisphere and you're fine.

Problem is on AX-150 I can not change IP from Navisphere. To change IP I need to re-initialize system: To reset the system, power it down by pressing the power button located on the back panel of the storage system. This will initiate an orderly shutdown that can take several minutes to complete. Once the AX150 has turned itslef off, press and hold down the  power button for four to eight seconds. When you release the button, the Storage Processor boot LED starts falshing. Once the LED stops flashing, the array has booted and is completely uninitialized. You can then run the initialization utility to set the username and password and IP address.
My question that what will be with my existing LUNz after this procedure.
