RE: Appending backups to tapes
by Fox, Adam 24 May '01

24 May '01

It should be. It kind of depends on the software you are using. If you're just using our dump and mt commands on the filer, then just use non-rewinding tape devices and dump again. Then when you do finally rewind you can use mt to fast forward past a specific number of EOFs. Other backup software may have this feature built-in and I can't speak for most of them, but at least natively it's possible. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com > -----Original Message----- > From: John F.

I need to retract this statement. I was working off of outdated info. This does *not* work. However, the on-board on the F840 does support VLAN tagging (which I think was another one of your questions). I researched this while I was verifying my first response. Sorry about that. Was working off of faulty memory cells. :) -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com > -----Original Message----- > From: Fox, Adam > Sent: Wednesday, May 23, 2001 5:22 PM > To: 'kevin graham'; toasters(a)mathworks.com > Subject: RE: interface fun > > > > > > Since I don't have the extra interfaces to play with, does > > anyone know if > > a VIF made up of vlan'able interfaces can also be vlaned? > > Rolling all of > > our interfaces into a VIF then VLAN'ing that would be > beautiful, but I > > don't want to go to the trouble having someone persue it if its not > > currently feasible. > > This is in fact true.

NetApp F720 -- Password recovery
by Rafi Khardalian 23 May '01

23 May '01

Anyone know how to reset the password and configuration on an F720, without physically having the boot disks? In the past, I called NetApp support with the same problem, at which point I was given instructions on how to emulate a floppy boot. Unfortunately I misplaced this valuable piece of information. The only part I recall is setting a variable at the "ok"/bios prompt named something like ?floppy-boot?. Help would be greatly appreciated. Thanks.

This is in fact true. You can create a big vif and then use vlan tagging to get up to 4 vlans per vif. This requires at least ONTAP 6.1. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com

On a pre-6.0 system, you halt to the ok prompt, then do the following: ok setenv floppy-boot? true ok boot Then part way up it will ask floppy booy? Type yes, then you get to the 1-5 menu. 3 is password recovery. Just remember to unsetenv that variable when you are done. Otherwise everytime you reboot, it will stop and ask if you want to floppy boot. This could be a real pain down the line. If you are on a 6.x or later, you can hit CTRL-C at a sepcified time (it will tell you) in the boot process and it will go there automagically. Of course, we ALWAYS recommend having working boot floppies around just in case. It's a good idea for emergencies. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com > -----Original Message----- > From: Rafi Khardalian [mailto:toasters@pennyweb.com] > Sent: Wednesday, May 23, 2001 4:33 PM > To: toasters(a)mathworks.com > Subject: NetApp F720 -- Password recovery > > > Anyone know how to reset the password and configuration on an > F720, without > physically having the boot disks?

interface fun
by kevin graham 23 May '01

It seems that .1Q isn't supported on the 760's onboard 100mbit interface and that only the "FastEnet-10/100 Ethernet Controller" will do it (besides the gige ints). Is this the onboard for the 840, or is it orderable as a separate part#? Since I don't have the extra interfaces to play with, does anyone know if a VIF made up of vlan'able interfaces can also be vlaned? Rolling all of our interfaces into a VIF then VLAN'ing that would be beautiful, but I don't want to go to the trouble having someone persue it if its not currently feasible. Also, does anyone know the difference in the GigE II and GigE III? I know the I was an Alteon, the II is an Intel, how about the III? I was wondering about jumbo framing in a VIF, and noticed the SAG said jumbo frames were available on a trunked GbE II -- should this reead Gb III instead? since the GbE II only does 1500 in standalone, why would the the limitation go away in a vif? Docs also state that mixed MTU's are unsupported. While this makes sense for a multimode trunk, it wouldn't seem to be necessary for a singlemode (ie, the vif adopts the mtu of the active interface). Does Ontap enfore the lowest mtu of all interfaces irregardless of trunk mode? Thanks.. ..kg..

740 ndmp backups
by Leonard, Roger 23 May '01

23 May '01

I am backing up a 740 with veritas using the "3 way ndmp" config. i.e. the 740 is backing up via ndmp to an 840 with a dlt8000 directly attached to it. the network is ATM LANE with combo of 1.5mbps and 622mbps. my performance is real bad, like 1 mb/s for a backup. has anyone had any experience with this type of scenario and have any suggestions?? i am going to try the NFS type backup as an experiment but would like to get ndmp to work properly.

RE: BlueARC SI7500 NAS

Can you please,sir, educate us all on how BlueARC has suceeded in making their disks spin faster than all of the other storage companies? Assuming most people can't afford 3 TBs of memory for their storage systems just how do they get around the mechanical latenices and rotational latencies of a rotating media device(which btw, is what WAFL is good at doing)? -----Original Message----- From: Dilbert Dickweed [mailto:blome840@hotmail.com] Sent: Tuesday, May 22, 2001 3:02 PM To: toasters(a)mathworks.com Subject: BlueARC SI7500 NAS Obviously nobody here has really touched one from the statements made. I have and have done direct compare between IP4700 (EMC) and 840 as well as the BlueArc box and it is very refreshing. It is true that some of the feature set is not there yet but they do have NDMP and unlike Netcrap, back-ups online don't crash the server. I have done my own IOmeter tests with various settings using some FreeBSD clients and this thing blows away 840 and IP4700. IP4700 is a joke anyway. Those who are in doubt (as I was) need to check these guys out because they are really onto something huge here. We are talking about eliminating the bottlenecks that exist in ALL server architecture today and reaching the next level of speed. I am not talking out-my-ass here...check 'em out! See for yourslef and don't listen to the dinks from Netcrap or Evil Machine Corporation EMC! If you do manage to get a beta unit as some have, make sure you get the failover cluster because this works much better than anything I have seen yet....
