RE: adding new DS14mkII shelves
by Francett, Robert D (SAIC) 12 May '05

I think he's wanting to add several FC shelves, starting with address 1, to an already existing FC adapter, hot. Add & configure shelves, or at least the first one, turn on adapter, away you go, filer doesn't hiccup (gulp!). I've also added shelves hot when there's already at least one up, but haven't tried what he has in mind - if I understand 'the plan' properly. -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Skottie Miller Sent: Wednesday, May 11, 2005 3:21 PM To: Michael Schipp Cc: rob-7704(a)austin.rr.com; John Stoffel; toasters(a)mathworks.com Subject: Re: adding new DS14mkII shelves Hot adding ds14 shelves not only works, it's supported and documented by NetApp. I've installed many a shelf live, on 9x0 filers and R200 systems. -skottie -- Scott Miller skottie(a)DreamWorksAnimation.com

Snapmirror and locked files
by Umerov, Mark 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

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.

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

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.

Snapmirrors force a lot of disk write IO, and hence a lot of CPs. That's both when when a snapshot is created, and even more when a snapshot is deleted. If your filers do a lot of writes in general, then you might be maxing out CP. When you reach the state of being in back-to-back CP's, then the filer starts not honoring Read requests, so that it can finish flushing its writes. Run "sysstat -u 1" and watch the CP columns. I'd bet that during the problem, you'll see that you're in CP continuously, and that you end up seeing #'s or B's in the CP type column. (I'm speaking for ONTAP 6.4.x - but I don't expect that this has changed much in 7.x.) Davin.

OnTap 7.0.1 and Legato Network 7.2
by John Stoffel 06 May '05

06 May '05

Hi all, We're about o refresh our Netapps and move to OnTap 7.0.1 and back them up with Legato Networker 7.2, and hopefully NDMP, though we currently do NFS mounts to the (Solaris 5.8, E450) backup server. We'd like to setup one large aggregate, with a small root FlexVol and a large large large data FlexVol, with a bunch of qtrees inside the flexvol. So what are others doing to make their backups run quicky, and their restores to run reliably? I've got the release notes for Networker 7.2 and I see the limitation of one (1) million files in DAR restores, and since I know our volumes have lots more files than that... it could be a problem. But maybe if we broke down our backups on a per-qtree basis, that would work? What are other people doing for backups? Any gotchas or performance tuning hints would be appreciaited.

This program will take a directory (or directories) and reset the permissions for each found file, based on the file permissions inside of the related snapshot directory. For instance, if you have: bash-2.05b# pwd /home/johnk/tmp/netapp bash-2.05b# ls -l total 1264 ---------- 1 root wheel 24 Oct 7 2004 e0_20041007_132410.trc ---------- 1 root wheel 24 Oct 7 2004 e3a-4_20041007_132410.trc ---------- 1 root wheel 1286589 Oct 7 2004 e3a-8_20041007_132410.trc ---------- 1 root wheel 24 Oct 7 2004 e3a_20041007_132410.trc ---------- 1 root wheel 24 Oct 7 2004 e3b_20041007_132410.trc ---------- 1 root wheel 24 Oct 7 2004 e3c_20041007_132410.trc ---------- 1 root wheel 24 Oct 7 2004 e3d_20041007_132410.trc ---------- 1 root wheel 24 Oct 7 2004 lo_20041007_132410.trc bash-2.05b# and the snapshot looks like: bash-2.05b# ls -l /home/johnk/tmp/.snapshot/nightly.1/netapp total 1264 -r-------- 1 johnk wheel 24 Oct 7 2004 e0_20041007_132410.trc -r-------- 1 johnk wheel 24 Oct 7 2004 e3a-4_20041007_132410.trc -r-------- 1 johnk wheel 1286589 Oct 7 2004 e3a-8_20041007_132410.trc -r-------- 1 johnk wheel 24 Oct 7 2004 e3a_20041007_132410.trc -r-------- 1 johnk wheel 24 Oct 7 2004 e3b_20041007_132410.trc -r-------- 1 johnk wheel 24 Oct 7 2004 e3c_20041007_132410.trc -r-------- 1 johnk wheel 24 Oct 7 2004 e3d_20041007_132410.trc -r-------- 1 johnk wheel 24 Oct 7 2004 lo_20041007_132410.trc ...this script will reset all of your broken root owned files, to be owned by 'johnk' with the correct permission bits (as found in .snapshot). http://www.southwestern.edu/~johnk/scripts/NAfixperms/NAfixperms-v1.6.pl Please use caution when using this script, as I am an amateur perl coder (things may not be done "correctly").

RE: VFM and DFS
by Louis Elias 05 May '05

05 May '05

Guys, I have no intention of vendor slamming or trying to sell anything. However, once again, for the sake of posterity (and accurate technical knowledge) I am compelled to set the record straight. This unsolicited slam on VFM, DFS, or whoever the intended target was is very inaccurate. I will only respond to the inaccuracies. Please see my responses below. 1.==================================================================== [Original] VFM or NuView StorageX (they are the exact same product) is an enhanced management GUI for Microsoft DFS with some additional hooks for automating failover in a NetApp(and other?) environment. [Response] Actually, StorageX is an integrated set of applications that enables enterprises to build unified, global namespaces across CIFS and NFS protocols and enables administrators to perform policy-based heterogeneous data management activities without interrupting end user access to data. These policies automate data and storage services, such as: heterogeneous network data management, data migration and consolidation, business continuity, storage optimization, data lifecycle management, remote site data management, and data classification and reporting. Yes, VFM/StorageX supports Microsoft DFS, as well as NFS. It is used to manage data on platforms such as Windows, NetApp, Linux, Unix, Netware and much more from a single, easy-to-use GUI. 2.==================================================================== [Original] If there is anything Microsoft hates more than anything else, it is telling a customer that they need to purchase a third party product to manage a Microsoft service. This means that either A) Microsoft is going to purchase technology so that they can give it to you for free or B) they are going to develop technology so that they can give it to you for free. Either way a commercial third party product for managing DFS has a relatively short shelf life with a fairly steep price tag if you have significant amount of storage. [Response] What backup software do you use and why aren't you using the built-in Windows backup software? Using VFM/StorageX reaps many benefits for organizations, including those that are currently running Microsoft DFS. The truth is that VFM/StorageX is not limited to managing only DFS, nor does it come with a steep price tag, despite the author's assertions. We have many advocates at Microsoft that like us because we make DFS scalable and offer an alternative to FRS (which caused their field much pain). Microsoft likes anyone who promotes their technologies. 3.==================================================================== [Original] NuView knows this and has started bundling additional "modules" with their StorageX/VFM product to make it a more attractive solution. [Response] We never set out to be a DFS management tool. VFM/StorageX is an integrated suite of applications, which are not bundled modules, rather they are included as part of the product as a whole. There are instances of customers who initially purchased VFM/StorageX for a migration project and later found that they didn't have to purchase additional software for archiving, or to create global namespaces for uninterrupted user access to their data, since it was already in StorageX. The reality is that hundreds of customers love the integrated applications and continue to leverage it, while managing and moving multiple terabytes of data. 4.==================================================================== [Original] All I can say is that you need to take a close look at where it has been installed and ask to talk to customers that have implemented the add-on modules to see what level of success they have seen. [Response] There are numerous cases studies and customers who freely talk about the immediate and long-term benefits that their organizations have gained, since implementing VFM/StorageX. Another aspect that one needs to look at is how long a vendor has been providing these solutions, as well as what the industry says about them. Finally, one only needs to look at the recent industry awards that VFM/StorageX have received to see that VFM/StorageX is a cost-effective, scalable solution that can manage the unstructured CIFS and NFS data of medium and enterprise customers. 5a.==================================================================== [Original] If you are considering a 3rd party tool to configure and manage your DFS environment you should understand a couple of things. 1) You MUST be running MS Server 2003 for your DFS root. Win200 is missing some key functionality and stability enhancements which will create a less than stable and less than scaleable DFS environment. Even VFM/StorageX require a Windows 2003 Server./ Their GUI is just that, a "better" GUI for administering DFS. It still requires MS Windows DFS. [Response] The author would do well to familiarize himself with chapter 17 of the 2000 resource kit before making assertions about DFS. Most of our 300+ customers are running DFS on 2000. 2003 lets you host more than one root on a single box and improves site referrals. I don't know how it is more stable. DFS is stable. It is part of the CIFS protocol. 5b.===================================================================== [Original] 2) Your DFS root will either need a Active Directory Domain Controller(s) or a dedicated DFS root server (cluster) depending upon the size and complexity of your environment and the level of authority you want to assign to your DFS administrators. [Response] DFS roots are stored in the Active Directory (domain-based roots) or in the registry of a server (stand-alone roots). This does not mean the roots are on DCs. The benefit is that VFM/SX is software and therefore you can leverage resources you already own, rather than purchase additional hardware or an appliance. The other benefit is that you can adjust the configuration and storage of your resource as you see fit and without affecting your CIFS/NFS management. VFM/StorageX supports and can leverage Active Directory, but it isn't required. 5c.====================================================================== [Original] 3) If you want to delegate the administration of DFS to less than domain administrators, you cannot install your DFS root on your AD domain controllers. You will be implementing distributed domain DFS. This means you need one or more clusters of DFS root servers to insure the availability of your DFS resources. [Response] It is not best practice to load a DFS root on a DC as field experience has shown. You can grant a user rights to the DFS configuration bucket in AD without making that user an admin. But most of our customers are domain admins so that seldomly comes up anyway. It is common to use one domain admin-like account to run the VFM service under and then delegate authorities through VFM. (pretty cool as MS did not provide this granularity.) 5.d====================================================================== [Original] 4) If you install DFS on your domain controllers, you must create a domain administrator account to administer DFS. [Response] Not a true statement although it does make things easier. We have customers not using domain admin accounts to manage DFS. See the above response. 5.e====================================================================== [Original] 5) DFS R2 is currently in beta. Patches have been released in December and again in 2005 (March?) which have significantly improved the Microsoft tools for configuring and managing DFS. If you are seriously looking gat DFS, contact Microsoft and ask them to come in and show you what they have currently available for free before you spend any significant time or $$ or a tool you will have to pay for. [Response] Since R2 is still in beta we can't discuss specifics, but we agree that customers should evaluate R2 and they'll find that VFM/StorageX fully supports and enhances R2. It's important to recognize the environments that R2 supports and for those that aren't supported under R2 or those that desire additional value-add can leverage VFM/StorageX. Finally, benefits have been realized by customers who initially chose DFS and realized that they could immediately and seamlessly manage their roots after installing VFM/StorageX. 6.======================================================================== [Original] If what you are really looking for is a tool to transparently monitor, manage and optimize your storage environment, both CIFS and NFS and support multiple vendors without having to install software on your filers or clients, without having to install Windows servers and 3rd party software to manage your heterogeneous environment, there are significantly more robust solutions which integrate into industry standard global name spaces and which ELIMINATE downtime, not just reduce it. [Response] A final thought regarding product viability is further evidenced by the recent industry awards that StorageX/VFM has received in the past couple of months, including: * Network Magazine - 2005 Innovation Award for the "Most Influential" solution in the storage product category (April, 2005) * Redmond Magazine - Redmond Most Valuable Product award (May, 2005) * TechTarget's Storage Magazine and SearchStorage.com - 2004 "Product of the Year" Silver Medal in the category of storage management (December, 2004) You can download a copy of StorageX/VFM and test it out immediately in your environment. Sorry I had to do this, Louis

RE: Home directories become owned by root
by Sphar, Mike 05 May '05

05 May '05

Are you using "mixed" mode for security? Whenever I've seen that happen in the past it was become some windows admin made some global permissions change on a mixed-mode share. I never use mixed mode, personally. I just don't like it. I've never had sudden permission changes like that on my servers whereas a co-worker who uses mixed-mode has had them many times. Others mileage will probably vary. -- Michael W. Sphar - IS&T - Lead Systems Administrator SMBU Engineering Support Services, BMC Software -----Original Message----- From: Michael Coxe [mailto:mcoxe@opsware.com] Sent: Wednesday, May 04, 2005 2:33 PM To: toasters(a)mathworks.com Subject: Home directories become owned by root Hi, We have a Netapp using shared NFS/CIFS. Yesterday several accounts became owned by root. Users couldn't even cd to their homes via NFS, though from the Windows side all looked OK. As root from the administration server I couldn't access their directories either. I thought of restoring from .snapshot but those directories (nightly.o, etc) are also onwed by root and are inaccessable from the Unix side. The only way to allow access was to use SecureShare from the Windows side and change ownership from "root" back to the username. Files & subdirectories appear to be owned by the user but the Unix permissions are all set to 777, and they can't access these files/directories. I could reset them via SecureShare (and did so for 2 users) but they won't be what the user(s) originally set them to. Ontap: NetApp Release 6.1.2D1 Filer: F740 Anyone have an idea how I can restore the original ownership & file permissions other that restoring from tape. -- Michael Coxe, IT <mcoxe(a)opsware.com>
