EVA8100 / Veritas Enterprise Admin

I notice that on an EVA 8100 that we are running about 6 Exchange servers, EVAPERF shows FP1 on the EVA is being utilised highese. Read Requests are showing up as 2100 peak and write req is at about 800 peak. all other ports are at a constant 0 . none of the other ports are being utilised. why is this ?

thanks much,

Sajeev

Hi Sajeev,

You should check that your zoning is setup so that each server can see all the ports on the EVA...

Re: EVA8100 / Veritas Enterprise Admin

What multipathing software are you using ?

Re: EVA8100 / Veritas Enterprise Admin

If you are using veritas DMP, you want to be sure that you have the appropriate Array Specific Library (ASL) installed to support EVA8x00's and also (APM) array policy module.

On UNIX "vxdmpadm listapm all" to make sure you've got HP's A/A-A, active/active-asymetric.

Also, check "vxddladm listsupport all" to ensure that you get a listing for EVA8100 controllers (which will be HSV___ ).

Re: EVA8100 / Veritas Enterprise Admin

Oh, for windows... not sure, but there must be some way to determine the APM and ASL's you have installed and in play for Veritas DMP (dynamic multipathing). That is likely your problem--the multipathing software policy/configuration.

Re: EVA8100 / Veritas Enterprise Admin

Of course if you don't have a performance problem and know that failover of path will occur, do you really even have a problem...
