Also, why has using /16 networking come up twice this weekend? I've gone years without hearing of someone trying something like this and suddenly, twice in a weekend?
Why is the SAN bigger than a /26? Why so many addresses for something that should have so few?
The move from a /24 to /16 was due to a "MSP" claiming flattening out the network would solve vlan issues that were occurring.
A /16 is worlds beyond flattening. Flattening is /22 maybe a /21. But what you are showing isn't in the scope of that flattening, these networks are all over the place and can't be covered by a /16.
I am aware of that. This was all decided long before I came on board. Yet I am tasked with identifying the issues and as you can see there are plenty.
Right, but the SAN hasn't been flattened. The flattened network is somewhere else.
This is what the "MSP" has identified as flattening. All the 172 addressing is new.
so the 172.20.200.x and 172.20.201.x are now flattened.. but why where they separate in the first place?
How are they flattened? They are tiny.
they are flattened because they no longer require a router to talk to any address, the fact that there is a HUGE collision domain doesn't really matter from a flatness POV. But yeah, that was crazy, a /21 would have solved it, without a calculator, I don't know if a /22 would have.
They DO require a router, they are small at just /24 and unflattened. So to talk to each other, they have to route.
I thought he said they flatted the SAN network into a /16?
This is what the "MSP" considered flattening compared to the old /24 with VLANs.
They didn't consider it that, they just lied.

But this hasn't been done according to your pictures.. it was only done on the 172.30.x.x network.

The lying thing is very common for this vendor.

time to fire them and find another support channel.

Now that we've determined that there is a huge networking issues. Do you guys thing the Event ID 5120 issue is a connection issue to the SAN loosing connectivity and the cluster going into an auto pause scenario?
No reason to think so. I can't imagine how the weird networking would be related to an IO issue like that.

There is always something that you can do. Just report it. State the facts. Bring it to the attention of the people in charge. Let them decide what to do. Explain that you are curtailed by the lies and incompetence and that you aren't being allowed to fix obvious problems and that the work ordered hasn't been done. Let them decide if they care that they have an enemy in their midst or not.

We have slowly been getting our documentation as we run into it.
You mean you have extortion going on and no one has called the FBI yet? Why won't they give the docs?

We get them as we run into issues requiring the need for certain things. They essentially kept everything and only provided necessary information as needed. They were actually holding all MS licensing until the SR. Admin demanded they turn that over.

Essentially they are ensuring they are needed until the very end as the end game is to ensure all IT is brought in house instead of through a MSP.
