Some security questions/wishes
by Holland, William L 24 Jun '03

24 Jun '03

Setting up two new filers, F810 and FAS940, in a new installation. ONTAP 6.4.1 1. Is there a way that I can permit certain users to view filer configurations and statistics without their having the root password or being given full adminstrative access? 2. Is there a way to force logons to the filer (be it console, SSL enabled FilerView) to use Windows groups rather than having to hand out the root password? 3. Is there a way to allow certain people to perform manual snapshots without their being given full admin access? Something akin to a Backup Operator. 4. Along the same lines of 3 above is it possible to permit those same people to restore snapshots on particular volumes without their being able to access other volumes?

Netapp ISCSI and AIXL 5.2
by markallen＠micron.com 20 Jun '03

20 Jun '03

Has anyone had any luck configuring iscsi with an AIXL 5.2 client? I can't seem to get the client to communicate with the filer and thought I would probe the toaster community to see if anyone else has had any such luck. I got to work with Linux and that about it. Any ideas would be greatly appreciated. Thanks Mark Allen

F330 fun
by Daniel Mayfield 20 Jun '03

20 Jun '03

So a friend of mine gave me an f330 and four DEC BA350 shelves. The f330 needs nvram batteries (and more nvram simms if anybody wants to get rid of some, but that can wait. It has four simms) but now the challenge is to give this thing as much storage as possible. Because of the BA350s I'm limited to 1" disks (1.6" don't fit well in the cans). I'm wondering what the biggest disks I can buy are? I've got four narrow scsi channels so I'm assuming I can get 28 disks attached to this thing. 28*36 is ~1tb raw capacity (I figure 700-800GB usable?) The question is, can I put 36 gig disks on an F330? If so which ones? If not, then which 18s work, which 9s? This is for a home network, mostly for archiving video projects and recorded TV shows so I'm not looking to buy disks direct from netapp, nor am I looking for support for the filer. I'm assuming that when (hopefully not "if") something comes of Bill's hobbiest program that I'll be able to get OS media and licenses from that. I guess this goes along with the "how far past spec can you push a toaster" ideas that have floated past recently. daniel

Dave: An even better way for users to play with ONTAP is, of course, to use a "real McCoy" version of ONTAP running on an old NetApp filer head and FC shelf. If solely for the purpose of "experimentation" in the support of a production system, would NetApp be hung up on licensing issues? Thanks.

Microsoft iSCSI

Has anyone tried out MS's iSCSI implementation yet? I filled out their survey on http://www.betaplace.com but it provided no link to download so I guess I have to wait for them to mail it to me.
