I'm presuming you're filer is connected to an AD domain, right? Command Line: cifs domaininfo If so, you add your domain user to the local Administrators group using the above commands (it's no different than doing the same on a Windows box). I'd encourage you to read the admin guide mentioned above to familiarise yourself with CIFS administration on NetApp systems. If the issue is just locked user files, you can use the MMC on a Windows box to manage the controller and unlock files, etc. If the issue is with files incorrectly/intermittently denying access to user requests due to some other issue, I'd be interested.

On the console: useradmin help domainuser So, you would do something like this: useradmin domainuser add <domain>\<user> -g Administrators ...to add your ad account as a local admin. If you are using vfilers you'll need to do the same on each of them, eg: vfiler run <vffiler_name> useradmin domainuser add <domain>\<user> -g Administrators Once you are an administrator, you can manage CIFS shares/locked files/etc via the MMC. If you need more details they can be found by reading the CIFS sections in the 'File Access and Protocol Management Guide' which can be downloaded from support.netapp.com.

We're seeing similar issues, but still trying to narrow it down also. Will keep an eye on this thread. Regarding the MMC, you need to have an AD account which has admin rights on the storage controller. Start mmc.exe on your Windows PC/Server logged in as that user (or Shift-Right-Click and open as that user), then add the 'Shared Folders' snap-in and point it at the controller name. You should them be able to view/edit/manage shares, etc and also view Open Files. It's not uncommon to have to unlock files (eg when a user has left a file open on their laptop, etc).

We had a very similar situation recently. We were using volume snapmirror to replicate the templates datastore, then mount the mirror via NFS (effectively read-only). This worked well, and I setup a backup job in VSC so the VM admins to take a backup and effectively trigger a mirror update on demand without the storage guys needing to get involved. This was often used when a template was changed/created in the primary site, then they wanted to use it to deploy in the remote sites. However, they would obviously need to wait for the backup/mirror update to complete. This worked OK, and the number of template changes is minimal so we never encountered any issues with the templates changing during use, but I would imagine that is a possibility. We've now changed this:- our license bundles include FlexCache, so I've changed this to use FlexCache volumes. This has the advantage that changes are recognised immediately. ESX has mounted the cache vols read-only to avoid changes being made by the remote vcenter boxes, but you could theoretically allow this (as long as you accept the write latency is going to be poor). If we lose the WAN, we lose the caches (it's set not to retain the cache on loss of connectivity), but we accept that. Worst case (or in a DR situation) we can still go back to mounting the snapmirror destinations. Anyway, hope that helps in some way! Craig

Hi Adai, Quick question: What/Where does the xml go to define custom events and event classes on OC? Today I run a script manually to check my snapmirror destination vols are >= the autosize max set on the source vols, and I'd like to generate custom alerts/alarms in Ops Manager if the script finds any that are non-conformant. One of many possibilities!! Thanks, Craig

sysstat and client-side monitoring will give you the number of protocol level operations. These are not the same as disk ops. ONTAP will build up the writes in memory (and NVRAM) and commit writes when the NVRAM buffers are full. these will be organised in memory to form contiguous chunks of data, and written in chunks. Try using statit to get more info around the number of IOPS each disk is doing - that should make more sense.

GARDINEC_EBRD · ‎2012-11-13

Not much to be going on with here, but at a quick glance your disks look busy (Disk Util) and you're in consistency points most of the time (CP Time), so I'd guess you've not got enough disks. However, you also have around 2X the amount of data being read from disk as you have going out the network. If I was a betting man I'd say you've got your VM's are misaligned (check with mbrscan, etc), which in turn is driving your disks too hard. Check block alignment, and consider more or faster disks. Hope that helps, Craig

Sorry to re-visit an old thread, but having read through I'm wondering if it should be possible to run VSC and OCHP 1.1 on the same host (the vcenter server) with VSC version 4.0 as opposed to 2.x? I've tried it here, but I get the following issue during the host package install: I've checked that the IP address for vcenter is correct, and the hostname blanked out above is also correct. Does anyone know if this should work? Thanks, Craig

GARDINEC_EBRD · ‎2012-11-08

Ideally gather a perfstat and send to NetApp support, but for a quick check in the meantime... During the period of high latency, run a sysstat -x 1 on the console. Firstly look at the 'CP ty' column, watch out for any 'B' or (worse) 'b'. This suggests your NVRAM is not big enough, or you're not flushing data to disk fast enough (busy disks). Also for a rough disk utilisation figure, check the 'Disk Util' column to see how busy the busiest disk on the system is. If the problem is NVRAM being full ('B' or 'b') you would normally expect ALL write workloads on the filer to be affected, not just those on the affected aggr. To see how busy the disks are, you can use statit. Hope that helps, Craig

Hi, Question from our DBA's: We’re about to start a smo 3.1 to 3.2 upgrade exercise. Our current 3.1 setup has two repositories which are held in separate Oracle schemas (PROD and DEVUAT) in the same database. We intend to use the rolling mechanism to upgrade host by host. Can you tell me at the end of this upgrade will we still have two Oracle user schemas (PROD and DEVUAT), or will the upgrade create new users and transfer data from the old schemas to the new schemas as part of the upgrade (so we end up with four Oracle users – two old 3.1 users and two new 3.2 users). Many thanks, Craig

Hi All, Sorry, I seem to be posting endless questions about vCenter 5.1... We're testing VSC 4.1 right now and have a problem with RBAC configuration. We have configured RBAC for vcenter as per https://kb.netapp.com/support/index?page=content&id=1013941. However, having installed VSC 4.1 and registering it with vcenter, we are getting a permissions issue when trying access the VSC in the vsphere client: If we change the roles to full admin in vcenter it works correctly, so there must be some privilege we're missing. Is there any updated RBAC doc covering VSC 4.1 on vCenter 5.1, or does anyone have any experience of this? Many thanks, Craig

GARDINEC_EBRD · ‎2012-10-31

Hi Andy, The simulators get installed with the same serial number, so you have to change one of them to use a different id. See: https://communities.netapp.com/videos/2513 Then you'll be able to add multiple sims to OC. Craig

Hi Himanshu, OK, thanks for the clarification. Regards, Craig

Hi, I'm just working through and upgrade plan for an environment using SMO 3.1 on HPUX and Linux over NFS, upgrading to SMO 3.2. According to the Install and Admin guide for SMO 3.2, the repository database needs to be upgraded after the upgrade of SMO. There seems to be a post-upgrade task to do this either as a whole repository upgrade or on a host-by-host basis using the rolling upgrade. My questions are 1) If I'm upgrading from version 3.1 to 3.2 is the repository upgrade required - it seems to imply this is if upgrading from a version prior to 3.1?, and 2) if it is required, are there any issues running 3.1 and 3.2 together (there are a couple of hosts still running Oracle 9i)? Many thanks, Craig

Sorry, but I don't think there is a way to see what individual vol usage in the cache is - as far as I'm aware, the stats only give usage, inserts, ejects, invalidates, etc across the whole cache. Would be nice if we could though... By the way, 97% usage is a good thing. Your cache should be as close to full as possible. It will keep inserting blocks until full, then you would see blocks being ejected (extremely overly simplified, but to illustrate the point). Craig

GARDINEC_EBRD · ‎2012-10-24

Not sure why this is, but I would start by going into the Operation Manager GUI, select the physical filer (eg Member Details -> Physical Systems -> filer), then select 'Diagnose Connectivity'. Check everything looks OK there, in particular at the end under 'Performance Advisor Checklist'

Hi Diego, Thanks for the info. That gives us a few more clues! Craig

GARDINEC_EBRD · ‎2012-10-19

Thanks Diego. We'll probably hang on until version 4.1 for production, but like some other folk, we need to get moving on vmware upgrades, so we'll plan to test 4.0 in our lab environment anyway. I noticed the release note for VSC 4.1 beta doesn't mention vCenter 5.1 support, it seems to be mostly a c-mode compatibility release. Do you know if there is any news or even an estimate on a release date for version 4.1, or any idea if interop between VSC 4.0 and vCenter 5.1 is actually going to be tested by NetApp? It would be useful to know either way. If this isn't going to happen, we can at least avoid investing time testing 4.0 ourselves. Thanks again, Craig

GARDINEC_EBRD · ‎2012-10-17

In IMT, when selecting VSC as the Storage Solution, there is no mention of vCenter 5.1 (only 5.0 update 1). When you say it's not compatible, does that mean it definitely will not work or that it is yet to be certified by NetApp/Vmware? We are also looking to update vcenter from 5.0 update 1 to 5.1, but have a reliance on VSC for backups, etc. Thanks in advance, Craig

GARDINEC_EBRD · ‎2012-10-16

Just re-ran the upgrade from 2.1.2 to 4.0 in test. This time, when the installer asked "Do you want to completely delete the contents of the Virtual Storage Console?" I selected No rather than the default of Yes. Now I still have my backups post-upgrade. It does actually say select 'No' in the install/admin guide on page 27 near the bottom of the page, but it is easy to miss.

GARDINEC_EBRD · ‎2012-10-12

OK, I thought that might be the case, but thanks for confirming. Do you happen to know if this feature is on any roadmap?

GARDINEC_EBRD · ‎2012-10-12

Hi All, Background: We're running SMO in a Unix environment over NFS. We're using SMO to clone databases, but some we are splitting in order to provide a base from which to clone several other DB's. We would like name these 'base' split clone volumes based on a particular naming convention. When SMO creates a clone it creates a flexclone called something like SnapManager_YYYYMMDDHHMMSS_<original_vol_name> so once SMO is finished we have to take the DB down, unmount the vol, rename it on the filer, mount it again on the unix host. Is there any way to tell SMO what to name the clone volume on the filer? I can define the mount point in the clone spec, but not the volume itself. Thanks in advance, Craig

GARDINEC_EBRD · ‎2012-10-08

Yes, we're using NFS datastores, plus VMFS via FC for the RDM mappings. Our vmware guy here is itching to upgrade to vcenter 5.1, so would be great if anyone has any target release dates for these. Yeah, we're wanting to upgrade ONTAP to version 8.1.2 which apparently includes a fix for CSB-1208-02. Also have some compatibility issues with SnapDrive for Unix & Windows, and some snapmanagers which need resolving before we can go to 8.1.x according to IMT. We're hoping to avoid having to go to 8.0.3 then 8.1.2 a short time later...unless there's a strong case otherwise. Thanks, Craig

GARDINEC_EBRD · ‎2012-10-08

Just trying the upgrade in a test environment, upgrading from VSC 2.1.2 to 4.0 on a vCenter 5.0 Update 1 server running on Windows 2008 R2. I have the same issue - lost all backup jobs...

GARDINEC_EBRD · ‎2012-10-08

Hi All, With vCenter 5.1 having been released last month, does anyone have any experience (good or bad) with it in a NetApp environment? We're currently running 5.0 Update 1, VSC 2.1.1, ONTAP 8.0.2 7-Mode and looking to upgrade vCenter in the next few weeks. Does anyone have any visibility into when it will appear in the IMT? Thanks, Craig
