VMware Partial/no Redundancy
Yesterday I made some changes ESXI5.5 servers which is a part if cluster (Vcenter5.5).
I have seen Partial/No Redundancy in Multipathing Status.
Attached the screenshot.
What could be the reason and how to fix?

You've stubbled upon a very old post from 2009, that's 7 years old!
ESXi 5.5 was launched in it's GA version 4 years later!
Check your paths, and re-check you networking.
do you have any paths down, do you have single paths to your LUNs ?

All paths up. No dead paths.
I can see like this on all datastores (see attachment)
I saw this as well now

If you check in your storage adaptors, you should have an even number of paths, if all paths are correct.
if you have an even number, then you are fine.
if you have an odd number, you have a path failure.

5 x 6 = 30
Yes, very good.
All correct, dual paths.

How you calculate 5x6=30?
5 for what and 6 for what?
5 for what and 6 for what?
Connected Targets = 6
Devices = 5
Paths = 30
Devices = 5
Paths = 30
ASKER
I changed as per your advise yesterday. now it shows 7 Connected targets and 5 devices

check all LUNs, and paths, to see if they are multi path.

I checked 2 Luns. All of then having 7 paths. Out if that 4 are Active and 3 are Active(I/O).

I have 5 LUNs i.e. 0 to 4
I can see 7 paths as per my network config. 4 active and 4 Active(I/O).
so it will be 35. Am I right?
I sent you the screenshot.

re-evaluate your networking and storage networking to your SAN.
