FS: F330
by Bill Bradford 10 Jun '01

10 Jun '01

Well, after a fruitless search for affordable (at least on my current budget) drives/cannisters for my F330, I've decided to give up and just get rid of it to someone that can use it for spares if nothing else. So: FS: One F330 According to people @ NetApp, this unit was probably a pre-release/ prototype/engineering model. Has a putty/beige front panel instead of a dark blue one, and the cover for the floppy drive area was either never finished or painted silver sometime before I got it. Has 2meg NVRAM (4 if I can find those other two NVRAM SIMMs), one DEC BA350 SESCSI drive shelf (no power supply or drives). No RAM on the motherboard, but we all know where to get that... System Serial # 02005 Email me if interested.. Bill -- Bill Bradford mrbill(a)mrbill.net Austin, TX

RE: Changing UIDs on LOTS of files
by Nail, Larry 08 Jun '01

08 Jun '01

One of our admins sent this out a couple of days ago... Might be helpful. Hi All, This weekend, I found myself changing the UID of all files which belonged to a particular user in ~40 directories. Since the majority of these directories contained snapshot directories, this task was impossible to complete within the time frame of the weekend without "pruning" the snapshot directory out of the find statement that I used. Since I expect that we will be seeing more and more need to perform this type of task with the merge, I thought that I would share the syntax that I used to accomplish this. Lets assume that I am changing the UID of all files and directories, within the current directory, from 444 to 555 and that I do not want my find command to run through the .snapshot directory. find . -name .snapshot -prune -o -user 444 -exec chown -h 555 {} \;

Greetings toasters, For network product planning purposes, I am taking a very brief & un-scientific poll on your use of NFS. Your participation is entirely optional but greatly appreciated. All replies will be kept confidential. Do you use: NFSv2, NFSv3 or both? If both, what % mix? TCP, UDP or both? If both, what % mix? CIFS, HTTP, FTP, etc. in addition to NFS? If so, what % mix? A layer 2 protocol *other* than Ethernet? If so, which one? Optional Bonus Round - What is (are) your: State, or country if outside the USA? Top three applications for filers? (one or two is OK as well) Application server platform(s) of choice? Ethernet speed (10,100 or gigabit)? In the interest of minimizing postings to the toasters list, please reply directly to me, arnie(a)netapp.com. Thank you for your participation!

NDMP is proven and has no problems. It is fast and reliable. If you have a Drive dedicated you can Direct attach the drive which is good and fast and has less overhead. I have a Adic Scalar 100 with AIT II Tape drives connected to Netapp and it works well for me.

Backup: Tape Libraries
by Puneet Gulati 08 Jun '01

08 Jun '01

Hi All, I just bought a F840 with 300gb usable but our growth rate is pretty rapid. One year from today the expected space usable will touch 1.5 TB. I am looking at two products for backup (using Veritas Netbackup 3.4/ data center running on a Sun Solaris 220R) that can handle it properly with good support and technology. This is what I short listed 1. Adic Scalar 100 with AIT II Tape drives. 4 drives( 2 drives for reserved for Netapp and 2 for other stuff ....) 2. Spectra Logic Bulll frog with AIT II but few months down the line I might have to upgrade to new drives which is AIT II (whenever sony releases it ) and/or buy another box. The tape library will be connected to Netapp using LVD running NDMP. Also the second HVD interface will be connected to 220 R which is my media server, master for netbackup. We are a startup and don't want to burn the cash instantly. Please help me with your feedback regarding the products and their support issues, if any, good/bad, will really appreciable. Thanks for your time for reading my e-mail/concern. If you have any question. pl. feel free to get back to me. Thanks, Puneet Gulati Afara Web Systems Email : Puneet.Gulati(a)afara.com

I believe we have the license for snapmirror, but have not been using it. Would snapmirror be a better solution in this situation? Is it relevant for snapmirror that source and destination volumes have different number of drives and RAID sizes? And that they reside on the same filer? Thanks again, Robert

SQL Server Performance Problem on Filer
by Dale Wolf 07 Jun '01

07 Jun '01

In case anyone remembers I wanted to let you know our local NetApp System Engineer discovered flow control was turned off for our environment. Once the network setting was changed we started getting better performance. Testing is continuing. I want to extend my thanks to all of you who replied to my email earlier in the week.

RE: Moving data from one volume to another
by Robert.Sabo＠ecomm.bc.ca 07 Jun '01

> In my experience, the quickest way to move whole volumes > within a filer is vol copy. There seem to be several concerns with using 'vol copy' in our situation: 1. The downtime - judging from our previous experience with 'vol copy', around 2 hours would be required to move 45 Gigs of data. 2. Someone has pointed out that 'vol copy' would not work in situation where the source and the destination volumes have different number of hard drives and different RAID group sizes. > If you need incremenal support, > then SnapMirror also works great. The only downside to SnapMirror > is it isn't free. Someone already suggested using SnapMirror, and it seems it could be a viable option for us. Is there anything not mentioned in "Data Protection Guide" (related to SnappMirror procedure) that would be relevant to our situation? > But do you really need "infinite incrementals" I mean you should > be able to do it with minimal downtime with only a few levels.

How long do you intend to strech it out? It has been reported in this tread that there are possible problems even with '-level 0' and '-level 1' backups with the Java version of NDMPcopy. Robert

Puneet, We using StoraeTek L 700 with 4 fiber attached 9840 tape drives ( StorageTek claims that their are the fastest on the market (?) ) Tape drives and NetApp and the SunBox 220r running NetBackup 3.4 are connected to a Brocade fiber switch. We have set up 3 zones on the switch with @ tape drives visible to SUN box ( for other backups) and other 2 tapes drives visible only to two NetApps. Runing NDMP backup, excellent throughput, after 6.1R no issues. Since each of the NetApp have a dedicated tape drive in the robot, we are able to back up efficiently through scheduled and user initiated backups. If you want more details I can send you a diagram.

Dumb and possibly impossible question
by Edward Hibbert 07 Jun '01

07 Jun '01

I'm having difficulty accessing NOW just now, so forgive me if a) this is on there or b) it's a stupid question. I'm debugging a client-side problem, using pktt trace from the NetApp. To assist with this I want to be able to go from the file handles I which I see in the pktt trace to a filename on the client. Normally I would try to to ls -i on the client to find an inode and work from there, but I'm not sure if that makes sense in a NetApp context. Any pointers?
