hi how can i monitor free Space for presented LUN at Exchange Server to know Free Space for this LUN. thanksAhmed Ali

Well, if you present the lun as one disk to the server and you use it as a whole you can use the windows server MP to monitor disk space. If you mean the part where you monitor the LUN perse you will have to monitor the storage itself.. so the SAN.Bob Cornelissen - BICTT (My BICTT Blog)

yes i presented the LUN as DISK for the server but scom can only see local logical disk not LUNAhmed Ali

Just monitor the logical disk.Regards, Marc Klaver http://jama00.wordpress.com/

Yep as long as the LUN = the logical disk.... (one-to-one relationship) than you can use that one. If it is dedicated the data will be the same.Bob Cornelissen - BICTT (My BICTT Blog)

Hi, As mentioned above, LUN should appear as logical drives the same as local storage. they can be discovered and monitored by SCOM.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Hi! Is this Server 2003 or 2008? You should really read the MP documentation for this (well you should ALWAYS read it :). There is a disabled discovery rule, called Discover Windows Physical Disks. If you enable this one (do it in test first) OpsMgr will discover the physical disks and create objects for these. Whether this works for LUNs or not, I can't tell. There does not seem to be any monitors tracking Free Space for Physical Disks so if this works, and you get the disk objects, you would have to build a monitor for this.This posting is provided "AS IS" with no warranties, and confers no rights.

Well actually in most cases people place 1 logical disk on 1 physical disk (and in sometimes this physical disk happens to be 1 san LUN. In that case you will not see any difference in the data. You can stay with logical disk counters. In some cases people partition a physical disk into two logical disks. In that case there is a difference and you can enable the physical disk monitors if you want to know the total impact of all partitions on that disk put together. If this happens to be a san lun again this is the same. Windows doesnt care much about san disk or other disk. It just activates and you place logical disks on it. If this is a 1-to-1 relationship I would suggest to monitor logical disk statistics which is already enabled. If you really want to look at it from another side you should monitor the SAN storage itself and see if you can drill down to LUN level in that, but that is not always the case. But this is not something the windows server will see as it just gets a disk presented to it.Bob Cornelissen - BICTT (My BICTT Blog)
