RE: Ait2 Robots supported?

I have been researching AIT2. FYI please look at http://www.spectralogic.com/NetApp/ which describes a SAN solution for multiple filer environments.

> Apparently the file uses the NT security model in the mixed qtree > and the file owner has locked himself and others out. If this is the case, you should be able to take ownership from NT. There was a bug with take ownership (#21325), which is fixed in 5.3.5R2. You should also be able to do a "chmod" or "chown" from NFS root and get control of the file. If that fails, you should do the rc_toggle_basic command "lock_dump -f" and see if your file is locked. These steps and others are all spelled out in the troubleshooter guide referred to earlier in this discussion. Let us know if you still can't solve this problem.

Check your routing tables with 'netstat -rn' is there a route to the other subnet? Is there a default route? Can you ping the router?

RE: Samba Vs CIFFS

It's not free like SaMBa, and SaMBa was a bit faster than TAS, but comparable. Regardless, I had a dozen or so Sun Ultra2 boxes running as many different CIFS servers, which could each support one development build, one NFS development build, and one CIFS development build. It was a pain to keep each of these suckers up to date and running. The Sun server could barely keep up with one NFS and one CIFS client. One upgrade choice was an 8 - 16 processor Sun box, to keep up with running all those TAS or SaMBa servers and NFS. I converted the whole thing over to a single 400 MHz 21164A processor F740 filer. Lock, stock and barrel. And, today, I'm still sane. We needed consolidation and horsepower. WAFL and snapshots and the other features mentioned were just icing on the cake. The microkernel-level CIFS implementation is just so much *faster* than SaMBa, TAS, or anyone else's user-level implementation. A lot of companies will tell you they have NFS and CIFS multi-protocol file sharing. But, if you ask them if they do it "natively," there are only three players we found: NetApp, EMC, and Auspex. My biggest problems today are adding more disk to support even more development sandboxes, and worrying about now managing a bank of filers. "An 800, an 800, my kingdom for an 800-series filer!"

Many enterprises have tried employing "free" software like Samba and even some vendors like SGI have tried to incorporate it into a "product"; hopefully some of these folks on this list will respond to your request but from working with "some" of these enterprises I can tell you from experience that Samba neither "scales" in the enterprise nor does it perform beyond about 75 clients doing useful work in a medium to large domain structure..it also is not an easy beast to administer( as explained to me be by several admins); it is "free" , however... Netapp glues the MS smb(cifs) code into our microkernel at the protocol level; Samba and other bolt-ons sit above kernel space as any other user app would and is subject to the context switching and shufflings that go on in a general purpose server; this (primarily) is why the Netapp CIFS solution both scales well and performs well as we add hundreds of users(see our Netbench results, for example); this is why the solution is not "free" -----Original Message----- From: Philip Thomas [mailto:thomas@act.sps.mot.com] Sent: Friday, May 26, 2000 11:03 PM To: toasters(a)mathworks.com Subject: Samba Vs CIFFS Hi, Why should some one pay good money to buy CIFFS license from NetApp when apparently the similar functionality is available "free", Samba?

If ICMP (ping) traffic can cross subnets, but CIFS traffic can't, I might suspect an access list on a router between those subnets is blocking TCP traffic (or specific TCP ports). You may want to check with your networking folks to make sure that they don't have access lists that are blocking your traffic. Also check your subnet mask and your default gateways to make sure they are working as well. As a last resort, you could try to run a packet trace on the network to see if packets are reaching the filer. Hope this helps. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com -----Original Message----- From: Uros Lampret [mailto:uros.lampret@ourspace.si] Sent: Wednesday, May 31, 2000 1:58 AM To: toasters(a)mathworks.com Subject: F740 and subnet problems Hi!

CIFS Woes
by Gunn, Billy 31 May '00

31 May '00

Is there a file similar to LMHOSTS for the filer. In attempting to implement CIFS after running an initial setup the filer is able to find a domain controller. After stopping and restarting CIFS or after some period of time it becomes unable to find a domain controller in which case the shares are unavailable. NT systems on the same subnet however are able to find a DC with the help of LMHOSTS. There are no DC's on the subnet in question however broadcasts are forwarded. I assume the filer is simply broadcasting for a DC and timing out rather rapidly. TIA, Billy Gunn Interadnet, Inc

RE: SQL Server 7 with data files on toaster?
by chris.hackett＠netapp.com 31 May '00

31 May '00

Colm, I was in charge of our Vantive database for the Sales department when we switched it over to a Filer for storage. Our internal sales group uses Vantive to track their contacts and leads. This application runs in an NT environment on a Dell Poweredge 6350 with four processors. Vantive itself runs on top of a MS SQL database. We connect all of the data files from this database out to a pair of clustered F760s. This has been in place since last December, and has been working great since. The system has only been down twice since we went to this configuration - both planned. Once to move the equipment to a different subnet, and a second time when we installed the CFO hardware. The Cluster Failover setup provides us with additional security and flexibility. Though, due to the stateful nature of CIFS, a successful failover requires some manual SQL Server intervention, we feel the overall configuration saves us time when we need to run scheduled maintenance on the Vantive Filer and provides us with availability should we experience unscheduled downtime of this Filer. As for the performance, it's great. In fact, I would say that if anything we have seen a slight performance increase due to the fact that many of the searches are repeated across many diffferent users (such as a search for all of the new leads from a particular tradeshow), in addition to all of the other normal reasons. Additionally, we have installed the SnapRestore software onto these machines and have snapshots running every hour. If something were to happen, we can recover from the snapshot taken at the top of the hour, instead of relying on the more manual process (where it has taken multiple hours to restore in the past). As you probably know, when we perform the SnapRestore, it's a simple reboot of the Filer, then we are working again. The value this provides to the Sales team is difficult to measure. If you have any other questions, please let me know. chris > > -----Original Message----- > From: Colm Buckley [mailto:colm@tuatha.org] > Sent: Friday, May 19, 2000 9:38 AM > To: toasters(a)mathworks.com > Subject: SQL Server 7 with data files on toaster? > > > > Hi - > > Another request for success or horror stories; does anyone on the list > have experience with running MS SQL Server 7 using a toaster to store > the data (as described in http://www.netapp.com/tech_library/3042.html > and http://www.netapp.com/tech_library/3044.html)?

RE: CIFS permissions
by rob.hawley＠netapp.com 30 May '00

The information below would imply that the user would get by the share permissions. It would still have to also get by the file permissions. You should also confirm the permissions assigned to your user by doing a cifs sessions -s. Here are two articles that will allow you to diagnose security problems: http://now.netapp.com/NOW/knowledge/docs/olio/guides/53_troubleshooting/ts2… l http://now.netapp.com/NOW/knowledge/docs/olio/guides/53_troubleshooting/ts1… l This is a more detailed article on the security model http://now.netapp.com/NOW/knowledge/docs/olio/guides/53_troubleshooting/con… .shtml If the answer does not fall out of the above troubleshooters (or you need access to NOW), please contact customer support. I would suggest having the qtree type, the output of cifs sessions -s, and the reported ACL for the directory you are trying to write to available when you call. You should also report the version of the filer and the version of the client. They should be able to solve this very quickly. -----Original Message----- From: Gunn, Billy [mailto:bgunn@InterAdNet.com] Sent: Tuesday, May 30, 2000 2:20 PM To: 'toasters(a)mathworks.com' Subject: CIFS permissions Hi.
