VNX Unisphere Error code 0x7211, 0x740a, 0x7409, 0x7404, 0x724b, 0x7211

Hi. I checked available our old storage VNX5100, VNX5400,

but connected unisphere error code many occured,

I don't know how about resolve errors..

This storage alert history are below.

0x724b(The following hosts have initiators that no longer have an active connection to the storage system)

0x7404(SPS is faulted)

0x724a(There are hosts whose initiators may not be connected to a storage group properly)

0x7211(Server ~~~ has some HBAs that are active but not registered ~)

0x740a(DAE 1/1  is faulted)

0x7409(DPE 0/0 is faulted)

I excepted disk faulted alert.

I wonder if the alarm "SPS is failed" caused all the rest to happen.

If I replace DPE,  DAE, and SPS, Disks will they all be cleared?

please advise me.
