Re: SAN Connectivity
There is a document called hp san design reference guide. This has lots of best practices guides.
There's quite a few things to consider when connecting a server. Operating system stuff, drivers, hba, multipathing.
Is there something specific you are wondering about?

Re: SAN Connectivity
A) you need to zone the blade to the eva. You may have san switches in the enclosure where you can do this.
B) before that you should install drivers and mpio dsm and manager on the server. You should update the os with patches as well.
C) after these you can present the vdisk to the server. Then a rescan should give you the new disk on the server.
As for best practices there are things like block size on the disk. Queue depth on the hba. There depend on the service you are going to run and you need to do a bit of testing to tune this right. Often though the defaults are ok.
Have the primary path for the server to the eva via the controller that owns the vdisk on the eva.

Re: SAN Connectivity
is the server zoned in with the EVA?
when you add the host in Command View - did the EVA find it automatically or did you add the wwn manually? When you added it, which OS type did you chose?
What kind of HBA do you have? For Qlogic there is the tool sansurfer and for emulex the hbanywhere. These you can use to troubleshoot more.
Did you install the hba drivers and MPIO manager as well?

Re: SAN Connectivity
yes the server is zoned in EVA, earlier server was connected to HP EVA 8000 and we have formatted the server and need the SAN connectivity back.
I have installed the Mpio Dsm drivers but not the HBA drivers,let me search for the HBA drivers

Re: SAN Connectivity
In windows device manager - do you see any HSV200 devices? Or unknown devices?
Have you tried to restart the blade?

Re: SAN Connectivity
You didn't answer my questions about the vdisk/presentation. Can the EVA see the server? Is the server logged on to the SAN-switch?
Neither the one about qlogic san surfer, do check them out.
