Re: PDC
by Peter Valian 03 May '02

03 May '02

I understand its not supported. It was my belief that someone on the toasters list was able to get it to work something UNIX. Actually the latest version of samba is like 99% of the way there. I got my filer talking to it and passing authentication requests from clients to the samba box. it looks like I just have a permissions issue right now. I was hoping there would be some netapp enineers on here that can *unofficially* offer some tips. The main problem being password syncing between NT and NIS on unix. thanks, peter Puneet Anand wrote: > Hi Peter, > > Non Microsoft domain controllers are not supported with filers at this > time. > This is documented on the NOW site : > > http://now.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=15548 > > -Puneet > ____ > > > Peter Valian wrote: > >>Is anyone using something other than windows to be a PDC? i.e. LSI >>TotalNet, Sun PC Netlink, Samba? >> >>Any suggestions appreciated. >> >>-peter >> >>-- >>Peter Valian >>Network & Systems Administrator >>Southwestern University >>Georgetown, Texas >>-- > -- Peter Valian Network & Systems Administrator Southwestern University Georgetown, Texas 512.863.1586 office 512.863.1605 fax --

UDP v. TCP
by Peter Bryant 03 May '02

03 May '02

*** Before acting on this e-mail or opening any attachment you are advised to read the disclaimer at the end of this e-mail *** Coming out of lurk mode for the first time folks. Kit is 810 filer 12x72GB, 2xSun E250 each connected on private fibre 1GB link, legato Networker to DLT7000 drives attached to the Sun (no NDMP). We've moved on from dotHill SANnet. There's been some discussion I've been following about fast read/slow write (or the reverse). We had our first filer installed in March and whilst performance was OK, backup of 250GB was taking 18 hours or more. Suppliers and NetApp had configured for improved performance but to no effect. Thanks to the thoughts on the list we changed yesterday from UDP to TCP and backup dropped to 5 hours - the expected performance. Daft buggers had optimised performance across the fibre for TCP and not UDP! So all the tuning effort done by the engineers had had no effect. FWIW script is appended for anyone's interest. We're going to get UDP optimised now, because of the reduced overhead - as it is a point to point connection so only the filer and the server are on the fibre. So many many thanks to the list - saved our bacon!

DAFS and DDA
by Joe Luchtenberg 02 May '02

02 May '02

Does anybody in Toasterland have any real-world experience with DAFS and the DAFS Database Accelerator (DDA)? I have a slew of documentation, and I've put together a brief educational overview for a local Unix SIG meeting coming up soon. Would like to: - be able to assert that not only is it available today, but folks are actually using it (without naming names, of course) - understand and present any "gotchas" that may exist - incorporate other real world insights, comparisons versus other db storage architectures, etc. into my presentation Happy to receive any feedback at all either on- or off-list! Thanks in advance. Joe Joe Luchtenberg Dataline, Inc.

Samba 2.2.3a PDC
by Peter Valian 02 May '02

02 May '02

Im sorry if this topic has been beaten to death but searching the archive for weeks I cannot find the info I need. Has anyone successfully gotten Samba 2.2.3a to work as a PDC for OnTAP 6.1.2D3. Or rather, what recent versions of samba and ontap work? I can only find mention of samba pdc dated 1999...was hoping for something a bit more recent. The goal of course being syncing password between windows PDC and NIS. tia, peter -- Peter Valian Network & Systems Administrator Southwestern University Georgetown, Texas --

RE: Data ONTAP Upgrade Procedures
by Martin Hughes 02 May '02

02 May '02

My 2 pence: Let everyone know well in advance and schedule a time when everything front end can be shut down/disconnected. It's more painful and requires more scheduling but it reduces any risk of lost data/corruption if anyone is in the middle of an operations. Remember to check is any backups are still running, we got caught on this last week and took 1/2 hour to check that that all the TSM sessions had been disconnected. Disable autosupport before you reboot the filer each time, and check if it renables after booting. Saves a lot of calls and open support cases from NetApp support.

Anybody do any tests of performance increase by adding disks to a volume?
by Art Hebert 02 May '02

02 May '02

We currently have a couple of Netapp 760 each with a 7x18gb shelf in a cluster config. The best performance we can get out of this is about 10MB writes. So we decided to test out what a gig card would do for us and the best we could get was 16MB writes and 30MB reads. In terms of testing the number of disks in a volume we saw an increase in performance by using a 7disk volume as opposed to a 3 disk volume, but surprisingly we didn't see a substantial increase when we went to 14 disks in a volume. So have any of you been able to test and justify using 14 disks as opposed to 7 disks in a volume? Have any of you been able to get better than 16MB writes? It also doesn't seem to benefit by having one shelf on one FC-AL card and another shelf on another FC-AL card? It seems the entire performance from what I can tell is limited by the nvram size. (16MB, half of 32MB nvram), thoughts? We have determined its not the gig cards in our suns that is limiting it as we can get 100MB sun gig card to sun gig card.

Hi Scott, Thanks for the info. I think that I'd rather get another SCSI adapter in the NetApp. I was looking at one of Qlogic's cards because that's what NetApp uses, here is the card that I'm thinking about getting. http://www.qlogic.com/products/ultra_series/ultra_three.asp Let me know if you think this would work. Thanks, Blake ----- Original Message ----- From: Scott Gelb To: 'Blake Folgner' Sent: Wednesday, May 01, 2002 4:04 PM Subject: RE: Adic FastStore DLT You have an HVD interface on the F760. You need an LVD/SE (LVD supports 25 foot, while SE is much shorter...about .5-1ft) converter. If you check CDW or other online shops, you'll find an HVD to LVD/SE converter that will do the trick... However, it isn't a supported configuration. HVD is +-12V, LVD is +-7V, and SE is +-5V....most SCSI Adapters that are LVD also support SE.

I set the loaders SCSI ID to 0 and the drive to 1 and I have also tried other combinations also, keeping in mind that the SCSI card in the F760 uses ID 7.

Any help would be very appreciated. Thanks for your help. Blake

We tested with it off of both and it seems that the onboard is faster. Thoughts? Art Hebert Email: art(a)arzoon.com <mailto:art@arzoon.com> Arzoon IT Dept. Phone: 650 522-6061 Mobile: 650 444-8667
