RE: moving data from trad -> flex vols
by Kenneth Heal 06 Feb '07

06 Feb '07

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?

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.

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??

netapp certified expert
by Leeds, Daniel 30 Jan '07

30 Jan '07

has anyone completed the netapp certified expert exams? coming from a day to day administration level on filers for many years im interested in what sort of topics they cover and if they are geared towards the real world or more of a training course regurgitation. in so many other vendor/system certs the exams focus on trivial and unrealistic aspects of adminstration--for example, sun certs focusing on adding printers and users via the gui---puhlease. mostly im just trying to figure out if someone could reasonably take the tests on experience alone or do i need to shell out 15K plus on all the little courses to get the courseware and then cram that. thanks -- Daniel Leeds Senior Systems Administrator Edmunds.com

RE: Aggregate expansion
by Suresh Rajagopalan 30 Jan '07

30 Jan '07

Thanks for all the responses. This is to meet an IOPS objective. I've run reallocate scans on the LUN's before, but it is not clear if that has done anything. Does a reallocate scan force the data to spread out on more spindles? Suresh -----Original Message----- From: Blake Golliher [mailto:thelastman@gmail.com] Sent: Monday, January 22, 2007 12:06 PM To: Suresh Rajagopalan Cc: Borders, Rich; toasters(a)mathworks.com Subject: Re: Aggregate expansion That sounds fair. The thing you'll need to keep in mind is that all your data written to the 14 disks that you first created. After you add on the other set of disks, the data you write will likely be put there, since that's where the most free contiguous space is. So if you are adding spindles for the space you need, and not to meet an IOP objective, you should be ok. If you are adding more disks, in an attempt to give more disk iop resources to the already existing data set, then it's a bit harder. If you have enough space, you can use reallocate to re spread out the data across the spindles.
