Hey, Here are some helpful tips 1. Capture the output from the commands below on all controllers a. Controller1*> cifs shares b. Controller1*> qtree status c. Controller1*> wcc -s domain\joe 2. You can use SnapMirror or Robocopy to migrate data and retain ACLs. 3. Ensure the NEW volumes retain the same security style (Should be "NTFS" in most instances) 4. If something goes wrong consider these solutions a. Resetting the CIFS connection to Domain Controllers by running the " cifs resetdc" and " cifs sidcache" commands to clear CIFS SID-to-name map cache entries b. Run the "cifs access <share> -m" command to reset the Windows machine accounts access to the share. c. Ensure the Name Resolution and Authentication have been determined as working successfully. Here is a tool provided by NetApp that you can install on a Client machine and change a permission manually. http://support.netapp.com/NOW/download/tools/ssaccess/ Good luck!!

If you go to your "My AutoSupport" portal you should see a "Transition Adviser" option to help you understand the implications and possibility of migrating to C-Mode. You can pretty easily migrate volumes from 7-mode to C-Mode, but it would take some serious leg work to go back. I hope this helps.

Hey! If you have downloaded the latest version of VSC (4.2.1) you want to use an AD account. 1. You can install VSC non-disruptively and you want to do this on the vCenter server 2. Go to https://localhost:8143/Register.html 3. Type the host name or IP address of the vCenter Server and the administrative credentials for the vCenter Server and register. Then... Steps 1. Open the vSphere Client and log into your vCenter Server. 2. Select a Datacenter in the Inventory panel, and then select the NetApp tab. 3. If the discovery process does not start automatically, or if you want to discover new resources and update information, click Update on the Overview panel of Monitoring and Host Configuration. 4. Right-click any discovered storage controllers with the status Authentication Failure and select Modify Credentials. 5. Fill in the information in the Modify Credentials dialog box. After you finish After discovery is complete, use Monitoring and Host Configuration to configure ESX or ESXi host settings for any hosts displaying an Alert icon in the Adapter Settings, MPIO Settings, or NFS Settings columns. SET YOUR TIME OUTS ON EVERY ESXi BOX!!!! (This requires downtime) This is just to get you started, I took all of this from the document listed below. http://support.netapp.com/documentation/productlibrary/index.html?productID=30048 Let me know if you have any additional questions

Hey Scott, I'm sure you already checked this, but just wanted to throw it out there, [-clientmatch <text>] - Client Match Hostname, IP Address, Netgroup, or Domain If you specify this parameter, the command displays information only about the export rules that have the specified client match. You can specify the match in any of the following formats: As a hostname; for instance, host1 As an IPv4 address; for instance, 10.1.12.24 As an IPv6 address; for instance, fd20:8b1e:b255:4071::100:1 As an IPv4 address with a subnet mask expressed as a number of bits; for instance, 10.1.12.10/4 As an IPv6 address with a subnet mask expressed as a number of bits; for instance, fd20:8b1e:b255:4071::/64 As an IPv4 address with a network mask; for instance, 10.1.16.0/255.255.255.0 As a netgroup, with the netgroup name preceded by the @ character; for instance, @eng As a domain name preceded by the . character; for instance, .example.com

Hello, if you're looking to evaluate Data ONTAP in VMware maybe just try this, http://www.netapp.com/us/forms/ontap-test-drive.aspx I havn't used the simulator in a really long time, but if you right click the VM and look at the hardware, I think one of those is actually meant for VM player or something. (I think!) Here is the guide. http://support.netapp.com/NOW/knowledge/docs/simulate_ontap/Simulate_ONTAP_8.1.2.pdf

This should be addressed soon, but even though I hit that error every time I use VSC, it never limits any of my functionality. Are you unable to use any features because of this? Also 4.1 is the latest VSC available. Even though you will probably still hit that same error, it's probably best to be on the latest version. I think Java is also required (too many clicks for me to find the doc)

Checklist for troubleshooting CIFS issues • Use "sysstat –x 1" to determine how many CIFS ops/s and how much CPU is being utilized • Check /etc/messages for any abnormal messages, especially for oplock break timeouts • Use "perfstat" to gather data and analyze (note information from "ifstat", "statit", "cifs stat", and "smb_hist", messages, general cifs info) • "pktt" may be necessary to determine what is being sent/received over the network • "sio" should / could be used to determine how fast data can be written/read from the filer • Client troubleshooting may include review of event logs, ping of filer, test using a different filer or Windows server • If it is a network issue, check "ifstat –a", "netstat –in" for any I/O errors or collisions • If it is a gigabit issue check to see if the flow control is set to FULL on the filer and the switch • On the filer if it is one volume having an issue, do "df" to see if the volume is full • Do "df –i" to see if the filer is running out of inodes • From "statit" output, if it is one volume that is having an issue check for disk fragmentation • Try the "netdiag –dv" command to test filer side duplex mismatch. It is important to find out what the benchmark is and if it’s a reasonable one • If the problem is poor performance, try a simple file copy using Explorer and compare it with the application's performance. If they both are same, the issue probably is not the application. Rule out client problems and make sure it is tested on multiple clients. If it is an application performance issue, get all the details about: ◦ The version of the application ◦ What specifics of the application are slow, if any ◦ How the application works ◦ Is this equally slow while using another Windows server over the network? ◦ The recipe for reproducing the problem in a NetApp lab • If the slowness only happens at certain times of the day, check if the times coincide with other heavy activity like SnapMirror, SnapShots, dump, etc. on the filer. If normal file reads/writes are slow: ◦ Check duplex mismatch (both client side and filer side) ◦ Check if oplocks are used (assuming they are turned off) ◦ Check if there is an Anti-Virus application running on the client. This can cause performance issues especially when copying multiple small files ◦ Check "cifs stat" to see if the Max Multiplex value is near the cifs.max_mpx option value. Common situations where this may need to be increased are when the filer is being used by a Windows Terminal Server or any other kind of server that might have many users opening new connections to the filer. What is CIFS Max Multiplex? ◦ Check the value of OpLkBkNoBreakAck in "cifs stat". Non-zero numbers indicate oplock break timeouts, which cause performance problem Check these as well, 1. enabling SMB 2 on the controller and using SMB 2 enabled clients would give better performance than SMBv1. 2. Make sure there is not much latency between the Domain controllers and the controller 3. Need to make sure that no stale DCs are listed under the preferred DCs What's cifs.tcp_window_size set to?

Scott is right, but do you have any internal drives? or just a single shelf? You will get more space and I/O if it's just a single shelf and you build one massive aggregate, you usually wont peg a single 2220 or 2240 with just one shelf.

The only thing that's changed since NS0-154 to NS0-155 is the new features that 8.1 brought, If you know those, you should be good. Here are some highlights, - 64bit aggrs - FilerView is gone - Flash pools - Flash Cache (not PAM cards anymore) - Vol move - Aggr / Vol maximums that changed with 8.x - Data compression - New controllers that depend on 8.x (2240) - ESH / ESH2 modules for DS14 shelf are no longer supported ...I can't really think of anything else off the top of my head, but if you go to support.netapp.com > documentaiton > Data ONTAP > 8.1.2 7-Mode There is a section that will tell you all of the new stuff that has been released with 8.x, a lot of stuff changed after 8.1.x, and I doubt it made it into the test, but if you understand all the changes in 8.1.2, you're truly ready for the test. Then get ready to embrace C-Mode, which has drastically different material, but is where everything is going. (I think getting yourself prepped and able to pass the 7-mode test is a good idea though)

You can setup a "HA Pair" meaning you have two single controllers clustered together, so that in the event of a failure (controller, cable, nic, switch) the other controller takes over. C-Mode will enable you to cluster multiple "HA Pairs" together, and is pretty much the direction everything is heading. But 7-Mode is perfectly suitable if you only need two controllers in one "HA Pair". Here is a good NetApp 101 I found http://prezi.com/u5_9_ohfgowf/netapp-101/

Hello, This feature has been built into Data ONTAP's C-Mode OS, which is the latest and greatest from NetApp. But, keep in mind, this is a fairly new OS that works very differently than the traditional versions of Data ONTAP and is therefore unfamiliar to a lot of people. Swapping controllers is pretty straight forward, but requires downtime. Moving forward on C-Mode, no downtime is required when you're moving controllers around. If it's on a hypervisor, you can easily move stuff around with storage vMotion or whatever it's called on your specific hypervisor. Just curious, what protocol are the volumes you're trying to move leveraging? I don't know a ton about EMC, so i'm curious to know which feature they have that allows data migration without downtime while at the same time not making a full copy?

Hey Guys, hw_assist relies on the RLM or SP as this is what separates it from a traditional cf_takeover. It's completely supported on the 2240, but if you do not have a RLM or SP card it will not work. (the 2240 and all new controllers by default come with a SP, so your in the clear jbartlett)

Perfect! Glad you're trying to get a better understanding, always happy to answer questions for this cause 1. The disks are in an "active-active" pair, but each controller only serves the data that is assigned to it. So you have to balance the load as evenly as possible across each controllers. 2. If you're using 10g, it's easy enough to vlan each protocol and put everything over the 10g ports as it will be very challenging to max out this pipe. You can even do "multi-level" VIFs and use one of the 1gbit interfaces as a fail over to get better switch redundancy. 3. The vlans look fine, but just put it earlier in the RC file per the example below 4. Use any address you want, just make sure it's not on the same subnet as e0M <== DOUBLE QUAD CHECK THIS! Also, this is a lesser priority, but make sure ACP is not using the same first two octets as the SP. Here is an example of a config that would be suitable for you, --------------------------------------------------------------------------------------- #Created by ccoleman 11-30-2012 hostname hana01 ifgrp create lacp hana-01-10g -b ip e1a e1b vlan create hana-01-10g 14 109 ifconfig hana-01-10g-14 10.140.4.56 netmask 255.255.255.224 partner hana-02-10g-14 mtusize 1500 ifconfig hana-01-10g-109 192.168.5.28 netmask 255.255.255.0 partner hana-02-10g-109 mtusize 1500 ifconfig hana-01-10g-109 alias 192.168.5.20 netmask 255.255.255.0 partner hana-02-10g-109 mtusize 1500 route add default 10.140.4.1 1 routed on options dns.domainname domainname.local options dns.enable on options nis.enable off savecore -------------------------------------------------------- vlan 14 = CIFs vlan 109 = NFS w/ an alias added so I can alternate IPs when presenting datastores to VMware

hmmm..that is a weird looking RC file. you should probably run the "setup" command from each console and rerun the setup. When it comes time to specify the network interfaces use "e1a" and "e1b". I would read through the network documentation, because you can use LACP or MULTI for better throughput and redundancy. You can also just leave one port on stand by just in case a cable gets unplugged, switch fails, or the ports fails. http://www.netapp.com/templates/mediaView?m=tr-3802.pdf&cc=us&wid=83443832&mid=29853432 <== check this doc out. One you rerun setup, paste back your /etc/rc file again, and we can double check everything. I would do some digging on the DELL switches and see which "ifgrp" makes the most since for you. (they're called "VIFs" in this document, but they're called "ifgrps" now) Ping us back with any questions! If you're uncomfortable with any of this, it might be best to reach out to a NetApp partner and get some help on your initial setup. Reaching out to whoever sold you the NetApp will be able to assist you this this.

disk auto assign is good for when a disk fails it will automatically assign a global hot spare before a disk replacement arrives. But as you already mentioned, it's best to assign your disks to each controller based on your requirements. A good option for you is, Controller 1: Make 1 big aggregate with a raid-group size of "23" so you will have two even raid groups of 23, and one spare. Then assign these disks to controller 1. Controller 2: Make another big aggregate with a raid group size of "24" and 1 spare. This will give you the most storage, most iops, best position for dedupe, and a fair balance between the controllers. (you can increase the raid group size as you add more storage to keep even raid groups) Can you type "rdfile /etc/rc" and paste the output and I will show you where to make the necessary Ethernet changes. Just curious, what kind of switches do you have? We can leverage all of these ports for redundancy.
