Snapmirror and locked files
by Umerov, Mark 11 May '05

11 May '05

greetings, Does Netapp allow locking of files on snapmirrored (read-only) volumes? If so, how does Snapmirror behave if there are locked files on the target? Please advise if you can... thanks much in advance, Mark

Re: adding new DS14mkII shelves
by Jerry 11 May '05

We've just added DS14mkII shelves on the fly. The only catch for us was using ESH2 modules, you have to have the right version of ontap, or it panics the filer when you open the loop. And yes, once you have the propper requirements it's as simple as flipping the terminator. The drives are seen in 30 seconds or so.

I would suggest go with the latest GA release for 6.5 which would have lot of bug fixes..6.5 is one of the most stable release from Netapp... -V -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Constantin Bogomolnyi Sent: Wednesday, May 11, 2005 6:02 AM To: toasters(a)mathworks.com Subject: raid dp Hello, I have 2 f840 with 72gigsx35x2 , i would like to use the raid dp feature how stable is the ontap 6.5 ? can we use it in prod for only nfs + raid-dp + snapmirror thanks cb

Ultimately we can and will do this. There are certain parties here that claim this can be done live... I suppose I'm catering to their wishes. But a reboot after all the drives are seen is probably a good idea if I have the window. > Robert> Does it matter in which order I flip the terminator switch > Robert> and/or run the "storage" command?

Once you do the enable command, it will go out and > probe that adapter, so it should be physically all setup ahead of > time. > Our SE mentioned in a meeting weeks ago that adding shelves is as simple as cabling them up with Termination "on" and then flipping a switch thus my frame of mind. And in an existing loop that would be true. But these are new loops and the FC controllers have no drives on them and thus the FC controllers came up disabled. I just talked to him and we revised the plan to as you suggest. I'll leave the termination switch "on" and run my fiber cable from FC controllers to the Fiber based ESH's. Then flip the termination switch off on the first shelf and *then* issue the "storage enable adapter x" command last. I'm curious how long it'll take for each FC controller loop to "discover" all the drives. Thanks for your suggestion. -Rob

adding new DS14mkII shelves
by Robert K. Borowicz 11 May '05

11 May '05

I'm adding 8 DS14mkII shelves on Sunday morning. The new FC controllers are already in the Filer (FAS940 running DOT 6.5.4) and blinking away. I also slid the 8 trays in (very carefully) over the past 2 weeks and cabled the copper interconnects up in-to-out between shelves this afternoon. Sunday morning we'll shut the Oracle DB's down and do the following: 1. Run the Fiber cable between the FC controller A/B ports and the Fiber based DS14 shelves. (we installed 2 and are planning on putting 4 each shelves per FC controller) 2. Run the "storage enable adapter n" command. 3. Flip the Terminator switch on the Fiber IN ports of each of the 4 ports across the two Fiber based shelves. My question is: Does it matter in which order I flip the terminator switch and/or run the "storage" command? Should I flip the Terminator switch off and *then* issue the "storage" command? I'm thinking Terminator switch last.... TIA -Rob

RE: New certification path (NACP/NACA)
by Hill, Aaron 10 May '05

For the most part, I must agree. My only gripe is that the requirements have been relaxed significantly; I sat the FAS900 hardware and ONTAP Admin exams when they were still needed for the NACA. Then I sat the ONTAP Advanced and the 3 NACP exams for my NACE. Now I find you only need 4 exams to get to NACE ...... hmmmm. The exams were no nonsense, I either knew all my stuff and passed, or didn't know it all and failed. This happened with the Data Protection exam when the snaplock stuff was introduced in 6.5. So I had to update myself to pass the exam the second time. This was acceptable. There were no long-winded questions that tried to baffle me intentionally like many other vendor exams I have taken. NetApp ask you a question straight up and then you answer it, no unnecessary ambiguity that I could detect. Almost all the exam content is found in the course material as mentioned. It is also very wise to do a NOW search on the technology you are studying and basically learn and read as much as possible. The rest is memory training and as we all know, there are many tricks that can be employed to make that easier. Experience will make answering the troubleshooting questions a breeze. When I felt I lacked experience in a particular area, I read through the KB articles and found them very helpful.

File reconfigurations and upgrading to OnTAP 7
by Lance A. Brown 09 May '05

09 May '05

Greetings, Wanted to run this past y'all before actually doing it. We have a project under way to reconfigure how we are using our netapps (2 FAS940s and 2 F820s) and get thema ll upgraded to Data OnTAP 7. Our two 820s are nearly full, so upgrading them to OnTAP 7 and then getting everything into FlexVols was going to be annoying and drawn out for lack of spare disk space to create an aggregate and get the cascade of traditional volumes to FlexVols going. Instead, we are thinking of attaching a new DS14 shelf to one of our FAS940s which already has OnTAP 7 on it, copy all the data from an F820 to an aggregate built from the disks in the DS14. Reconfigure the F820 by removing old low-density disk shelves and upgrade it to Data OnTAP 7, and then move the DS14 on the FAS940 to the F820. Moving disk shelves and what not around isn't a problem. I'm familiar with that. The kink here is that we need to switch from ESH modules in the DS14 to LRCs when we move it from the FAS940 to the F820. Does anyone know if that will cause a problem? --[Lance] -- Lance A.

I fond the NetApp exams to be probably some of the best in regards to the following: 1) They do not ask questions that are on notes in the training materials. 2) The questions are all on relavent information that is contained in the training materials 3) There are 5 questions related to experience in working with the Filer This is done to help eliminate the 'paper' certifications. 4) On the above experience questions should not cause you to fail if you have studied the training material. 5) After any of the exams I've been able to go to the training material and find the answer rather easily.
