Subject: RE: Exchange over a SANYou are correct!! I too have an Exchange 2K server clustered on a SAN. (Compaq - StorageWorks) It is not a requirement to implement a SAN for your cluster. It give you the ability to work with your storage more effectively. With the Compaq SAN and several tools you do have the option to grow your storage on the fly!! NOTE: Microsoft does support SAN's with ExchangeChrisList Charter and FAQ at:-----Original Message-----

Subject: RE: Exchange over a SANSorry for the delay on the elaboration. Got pulled away.Here is our story:At the University of North Carolina at Wilmington we are moving from VMS based (pop/imap) mail system to Exchange and Outlook. We are running a Dell SAN over Fibre Channel and Dell PV servers. The SAN adds an extra level of complexity but is a must for clustered environment. Depending on the SAN you are implementing and its "ability" to have lun and or partition sizes changed on the fly, the "virtual" disk size planning plays a major role. With our SAN we cannot grow the partition on the fly. Any growth will require: downing of E2K, a GOOD backup, rebuilding of the LUN and partitions used, re-presentation of the luns, getting W2K to ID the proper LUNs, data restore, much prayer, bring E2K up.In short leave yourself plenty of room. I am currently allotting only .25 of available space to the mailboxes. The system default mailbox size is 20MB. There is a separate partition/lun for each of the 2 nodes in the cluster and another for the public store.The HBA's to connect to the SAN had issues with W2K SP2 and fail over would not work, this has been fixed (about mid year). A thorough understanding of the SAN and its fabrics is very necessary, Don't just have and outsourced implementation team come in and set it up, this will kill you if you need to troubleshoot.I can give more info to the list later if needed or offline.The quick synopsis:E2K on active-active clusterQuorum, logsx2,priv.edbx2, & pub.edb are on SAN partitionsNLB Front-End/OWA 2 node "cluster"Hope this a start for any questions, I can give a more "formal" elaboration after the weekend (taking some time off)--KevinUNCWList Charter and FAQ at:-----Original Message-----

Subject: RE: Error when backing up Exch. 5.5 (using MS backup)Diane,See my answers in context below:1. Is this a new Exchange setup? --Not really. The server's been up for over a year, but we just hooked up a SAN array & ran perf optimizer to redirect the store.We have seven servers total, & this is the only one with a problem.2. Has this ever worked? --No, not on this server. We normally use ArcServe, which worked fine until recently. (before you ask, the error was around _before_the SAN switchover)3. This is a dumb question, but....does this exchange server possibly still have circular logging turned on? --No. (I just checked). Good question, tho.(There are no "dumb" questions, only dumb answers.)4. How many log mdbdata log files do you have? --A whole bunch. Since I haven't been able to get a good backup, they're still there.5. If you can't get it backed up, you probably have many many days worth and a very full partion. --The SAN _greatly_ increased my storage capacity, it'sonly about 50% full. The problem has been around since it was 25-30% full, however.List Charter and FAQ at:Diane (picking at straws here.....)EricList Charter and FAQ at:-----Original Message-----

Subject: RE: Error when backing up Exch. 5.5 (using MS backup)Diane,
Yes, I have. It makes _no_ diff when the job runs. At the present time, I am only running the job manually and it still fails. Sorry, should've told you, the OS is Win2Kserver. I run the same job on two other, identical, servers with no problems. Now, I wouldn't even be using NTBackup, except that ArcSmurf choked on the backup. After reading about similar problems from other folks on this list, I thought I'd try using NTBackup to a file & then have ArcSmurf back that up to tape. Works like a champ on the other two servers, just not this one! Any other ideas? Should I try running some diags on the store?Eric
