replicating exchagne databse
by SKIP HOFMANN 21 Oct '04

21 Oct '04

Hi all We have our exchange DB on a FAS 250. We take 3 snapshots of the logs and DB everyday. I want to know if I can replicate the most recent snapshot of the DB and logs to my R200, and if a disaster were to hit could I copy this DB back to the FAS 250 and mount it? We use single mailbox recover version 2.11 to restore emails and inboxes. If point this product to the replicated exchange DB on the R200 It does work the product does read the DB and I can recover inboxes and emails. So I guess my question is a snapshot of a DB once moved off of a fAS250 to an R200 can it be remounted by snap manger for exchange once the DB is copied back to the FAS?

Exchange databse on a FAS 250
by exadmin 21 Oct '04

Hi all I am trying to make an argumetn for putting our exchange database (50 gigs) on a filer instead of a windows 2000 box with raid 5 array. We are running Exchange 5.5 Other than the snpshot technology what other benefits will we get with using a filer VS a windows box thanks a bunch This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

If the sole purpose for purchasing the filer is for this 50gig exchange database, it is probably not easy to make a good business case. However, if the filer is part of a larger storage strategy for your organization, it should be much easier to build a convincing business case. I think that the real benefits of NAS/SAN come from the ability to consolidate individual server storage and centrally manage. Other benefits include reliability, strong product support (at least with NetApp) and a proven track-record etc <insert marketing jargon here> For example; If you already connect Windows CIFS (or any other protocol for that matter) on the FAS250 then you may have already proven that the FAS250 works in your environment and that it provided some consolidation/management benefits. You should be able to show that the system is reliable and the performance has met expectations (otherwise you wouldn't be considering it for an exchange DB). If you have used NetApp support, chances are that you had a good experience. Moving more storage services to the FAS250 over time is what this entry-level device was designed for .... expansion, future-proofing, or whatever you want to call it. This is because it can fairly easily become a disk shelf in a larger F9XX series system if you choose to expand to an enterprise or high-availability (aka clustered/mirrored) storage solution. If you do expand, you should be able to do so without significantly increasing the amount of time spent managing the filer(s). Whereas adding a separate RAID array for every server/service could lead to considerably more time spent setting up and maintaining. On the surface, less moving parts (aka RAID controllers, servers, vendors) results in a simpler environment. Hope this helps seed some ideas for you.

Can you post any response directly to you that does not copy the alias? I'd be very interested in knowing the answer.

RE: Troubles with DATAPROTECTOR's HP backup software.
by Derek Lai 18 Oct '04

18 Oct '04

Any reason why you are on 5.0 as opposed to Data Protector 5.1? Data Protector 5.1 is the latest and has been out for a while. I've seen something like this when I first upgraded to Data Protector 5.1 and was trying to use NDMP backup. If I try to backup more than 1 object, it will finish the first object and then timeout. Go to /etc/opt/omni/datalists and look at the backup specification you have. Edit the file and remove the line "DYNAMIC 1 1". After that, the backup worked fine for me.

Downrev from 6.5.1R1 to 6.4.5

We have had some serious problems with NDMP restores since we went to 6.5. I have been unable to get either NetApp or my backup software company (Oracle - Reliaty Backup) to take it seriously.

parity drive rebuild causing ls hangs
by Jerry 18 Oct '04

18 Oct '04

Anyone ever experience really bad performance when rebuilding a parity disk? We had a parity disk fail on our FAS940 and when it was trying to rebuild the disk i/o util went to 100% (observed with sysstat). Reads and Writes did not appear high, but I don't think rebuild traffic effects those numbers. During this time, "ls" was taking between 30 and 60 seconds (unacceptable). We thought for sure this couldn't be normal, since we've had disks fail and rebuild many times. The difference this time is it was a parity disk, but I don't think that should make a difference other than taking a little longer to rebuild. Sure enough, after the rebuild was complete it started working again. Any opinions? Jerry __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
