RE: Replacing defective DLT7000 drives without rebooting the fil er
by Kelly Wyatt 07 Aug '00

07 Aug '00

We always power down the filer: Halt filer remove scsi cable from tape adapter boot filer ... 2-3 minute outage replace the drive. Halt filer attach scsi cable from tape adapter boot filer ... 2-3 minute outage Two short outages are easier to handle... yes, we have CIFS and NFS connections that are affected. In theory, since we schedule the outage, the users should be prepared... :-) We currently have 2 9710's but will be consolidating into one L700 -- which has, as you mention, hot swappable drives. But I believe that NetApp still recommends that you power down the filer. Would be nice if that was not so...

Lawrence, We have setup a NT4 server as a ScanServer with McAfee on it. We have a point to point connection between the Filer and the scanserver. (Don't forget to set the speed of the network card on the NT server to 100MB Full Duplex) We just map the cifs volume and scan the cifs volume over the point to point connection(to avoid network load). So far we are very happy with this solution and have been able to detect and remove viruses from the Filer. As soon that a virus is detected a popup window appear on my pc.

Nail, We have two F760 filers running CIFS only. We have about 3000-4000 client connecting to the filers from a number of sites. We are presently using McAfee Virus Scan 4.3.0 to scan both filers. We have set-up several high spec workstation each sweeping a section of the filers. We use snap mirror for disaster Recovery so have a combined disk capacity of about 1.1TB. The Virus scanning works pretty well but we are kind of unhappy at losing the on access scanning functions.

If the default raid group is increased the current and subsequent groups ONLY can be added to.

Don't have experience with that, but I can think of a siggestion: In you antivir script: rsh toaster0 options cifs.show_snapshot off <your antivirus part> rsh toaster0 options cifs.show_snapshot on This will hide the ~snapshot during antivirus check.

Jim, We're currently using NAV5 to do this however, we're having to move to Corp. Edition 7.02 because of Windoze 2000, so I'm looking for another command line driven virus scanner that I can use. On a side note, what are you using to exclude snapshots. My efforts to put ~snapshot in the exclusions have been futile.

move command on filer?
by Nick.Mayrath＠envoy.com 04 Aug '00

04 Aug '00

This weekend I need to move alot of files around of my F720. Is there any "move" command locally on the filer that I can use instead of using my NT machine? My concern is that using the NT machine will cause the moves to take longer since they have to "pass through" my NT box. Thanks

Anybody out there using Netapps for Usenet spools?
by kelvin tooth 04 Aug '00

04 Aug '00

Hi all, looking thru the archive of this list, I can't find any real relevant information about Netapp configuration details for usenet since 1997. Things have changed since then in both filer and usenet worlds. Anybody got any suggestions/gotchas/useful web links/tips for me? I am used to having news in an A5000 disk array, but would like to use netapp if possible. regards, Kelvin Tooth Internet Design Engineer Cable and Wireless

Q. on Qtree/Volume/RAID group
by Ng, Pok 04 Aug '00

04 Aug '00

I have few questions regarding qtree, volume and raid group 1) Is it ture that raid group is added to a volume automatically? 2) is there any command for creating new raid group? 3) when a qtree is created on a multi raid group volume, does the qtree span across all raid group? do you have control on which raid group the qtree can reside on? 4) when the max disk per raid group is increased, does it affect all raid groups? 5) I know if a new disk is added, it will be added to the last raid group of a volume. Assuming the answer to Q4 is yes, then what happen if the last raid group of a volume is filled and there exists raid group(not the last one) in the same volume that is not filled? TIA pok
