eva Health checks

[yamoo]

I  am planning the scope to carry out overall health check of our EVA and just wondering if any one could share his experience on this. I know combination of tools need to be used to gather data from the EVA,host and possibly the connected SAN switches to figure out any non-best practice configuration. but the questions is what are the elements to look for? Read in some HP service documentation that there are 25 elements- i take this as including, disk group,vdisk,DR,controller etc.. right?

So I will appreciate if you can share some guides on this .

Thanks.
