Snapshot question
by Miller, Michael CTR USTRANSCOM J2 07 Feb '07

07 Feb '07

I have a soon to be problem with snapshots coming up. I will be deleting a directory that has 238GB in it and I would really prefer this not to get captured by a snapshot if there is anything I can do about it. I don't want to destroy the exsisting snaps either. Does anyone know of any way to keep this out of the snap? Any thoughts on how to limit the hit?

moving data from trad -> flex vols
by René Bormann 06 Feb '07

06 Feb '07

Hello, we are running an FAS920 with FC9 shelfs with data and new empty DS14 shelfs. On the FC9 we got one volume /vol/vol0 with root and data on it. Last week we upgraded from ONTAP 6.5.6 to 7.2.1 without problems. Now we want to move our data to the DS14 shelfs. We created one aggr1 with lots of drives. After that we created two new flex vols - /vol/root (20GB) and an /vol/vol1 (1TB) for the data. We copied the root data with no clients on the filer with "ndmpcopy -l0 /vol/vol0/etc /vol/root/etc". Worked fine in 7 minutes. Than we change the booting volume with "vol options /vol/root root". Booting from it, no problem -but now by requsting http://filer-ip/na_admin just the first page came and we were not able to start the FilerView Web-App. So so we switch the root vol again with "vol options /vol/vol0 root" and FilerView works fine. In the message file we found that one: Sat Feb 3 09:16:09 CET [httpd.socket.listener.create:error]: HTTPS Initialization failure; could not create listener socket. Nothing else. Can anybody help?

HiThis does sound like SecureAdmin might be the source of these ills, take a look at http://now.netapp.com/Knowledgebase/solutionarea.asp?id=kb6282 and http://now.netapp.com/Knowledgebase/solutionarea.asp?id=kb6270.Basically what you would need to do is:Disable SSL by running the command:secureadmin disable sslRe-create the certificate by running the command: secureadmin setup ssland re-enable SecureAdmin by running the command: secureadmin enable sslIf you disable secureadmin before copying the vol across it may even work; I don't have a filer to hand to be able to test it.Viel Glück und Viele Grüssen!Kenneth> Date: Tue, 6 Feb 2007 23:13:31 +0100> From: bormann(a)bbtel.de> To: toasters(a)mathworks.com> Subject: moving data from trad -> flex vols> > Hello,> > we are running an FAS920 with FC9 shelfs with data and new empty DS14> shelfs.> On the FC9 we got one volume /vol/vol0 with root and data on it.> > Last week we upgraded from ONTAP 6.5.6 to 7.2.1 without problems.> > Now we want to move our data to the DS14 shelfs.

Script to automate Dev System from Production.
by Rod Newcomb 06 Feb '07

06 Feb '07

I am looking for some help. We have two MS SQL servers. One is running in production, and we are snapmirroring the data over to an offsite location. Since Snapmirrors are read only, we would like to use Flexclone to create a writeable copy of this LUN for our off-site SQL server to use. We also have SnapDrive and Snap Managager/SQL software available to us. The trick is that I would like to automate the following process: Snapmirror to our offsite location (done using SMSQL) Shut down SQL at our offsite location. (No Problem) Disconnect the LUN (Using SDCLI ?) Create a new flexclone from our Snapmirrored copy. (Lun Create ?) Reconnect to the new Flexclone LUN (????) Start up SQL Services. (No problem) I would like this process to run automatically every 24 hours. Does anyone have any scripts or suggestions on how I can do this? Rod Newcomb

RE: Vista and Netapp??
by Callaway, Michael 02 Feb '07

02 Feb '07

Can other non-visa clients access this CIFS share in the way you want your vista box to access it? Just because your user is in AD, doesn't give it permissions on the share. You need to make sure that user has access on the filer through group and user permissions as well as the shares have to be given to that user or a group that user is in. I would first make the exact same setup on an XP or 2000 box (whichever you have) and determine if it's a user setup problem or something that can be directly attributed to Vista. -- *--------------------------------------- Michael Callaway (Server Administrator) North Texas Tollway Authority http://www.ntta.org <http://www.ntta.org/> 214-461-2033 o 214-325-5523 m 972-930-2633 f ---------------------------------------- ________________________________ From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Brent Ellis Sent: Thursday, January 11, 2007 9:09 AM To: toasters(a)mathworks.com Subject: Vista and Netapp?? I am just starting to test Vista against our netapp FAS 3020c filers. We use these machines with the CIFS license for basic file sharing. The shares have Active Directory permissions applied to them and the servers have been added to AD. In Vista, I cannot connect to the servers using an AD account. Only the accounts created on the filer itself will allow me to connect from Vista. Has anyone run into this? Any solutions?

RE: NFS speed

I thought of that also. A normal file copy shows the same results.

Had no joy anywhere. Anyone have any thoughts on how to speed this up? I have thought about pulling the backup target in-house and using the Legato clone mechanism to get the data back to the filer but I doubt that would help much.

Steve I sure hope that is not the problem. I had gone down that line of thought but I keep coming back to the snapmirror transfer rates. I don't know the details of a snapmirror transfer but I would expect to see issues there also if latency was the problem.

Losen [mailto:scl@sasha.acc.Virginia.EDU] Sent: Wednesday, January 31, 2007 1:43 PM To: Miller, Michael CTR USTRANSCOM J2 Subject: Re: NFS speed Perhaps your problem is network latency rather than bandwidth. Perhaps you can send a large burst of data to the netapp (high bandwidth) but it takes a while for that burst to travel all the way across the network (high latency). In this situation a process on the NFS client sends a request and has to wait for the request to arrive at the netapp and then wait for the response to before sending the next request. During these wait periods, more data could be sent or received, so the network just sits idle for most of the time. If the load on the netapp is really low (which is probably the case) then I suggest testing this theory by firing up a bunch of parallel processes on the NFS client that each read and/or write a large file on the netapp. If the throughput goes up, then that probably indicates latency.

Re: wafliron output -- is wafl OK?
by Reinoud Reynders 31 Jan '07

31 Jan '07

On the console, he will give information when there are unrecoverable blocks. I'm not sure that he gives info when it's finished. But you can monitor the process (wafl scan status). Depending on the size of the volume, it can take a long time. You can speed up. This (give the process more priority, if you want).

Hi toasters... currently i am running a wafliron. My question now is, do i get any kind of output after wafliron has finished?? Do i see if there where any wrong blocks and if Ontap was able to solve the problem or not?? Or is there any extra command to assure that there is no problem in wafl left?? Regards and thanks for your help Jochen
