  1. Very useful page – thanks. There is a distinct lack of cli commands referenced online and I ended up specifically requesting the cli guide from EMC as I could not find a link to it on their website…

  2. where do i run these commands from? do i have to have the command line agent? currently trying to get av software to run on a virtual server with CAVA.

    1. The commands need to be run from a control station login. You can connect directly to the control station with a terminal emulator (I use putty). There is no host agent for the celerra that’s similar to the Navipshere CLI.

  3. Hi, how to verify
    – How many shares?
    – How many clients (windows vs *nix) ?
    – Which protocol (SMB vs NFS) ?
    – Authentication type (LDAP, AD) ?
    – Virusscan information (Cava server list, product version, etc..)

  4. Hi – we recently moved a celerra but now getting the following error messages after running the /nas_checkup script..
    Control Station: Checking if NBS clients are started………………….. Pass
    Control Station: Checking if NBS configuration exists…………………. Pass
    Control Station: Checking if NBS devices are accessible……………….. Fail
    Control Station: Checking if NBS service is started…………………… Fail
    Control Station: Checking if NAS partitions are mounted……………….. Pass
    Data Movers : Checking status……………………………………. ?

    Any help would be greatly appreciated .
    Thanks in advance..

    1. NBS is the Network Block Service, which is a proprietary client/server protocol of VNX/Celerra for file that provides a block device (for example,
      iSCSI device) management functionality over a TCP/IP connection. You can check the parameter by typing server_param server_2 -facility nbs -list, then check the settings for each parameter with server_param server_2 -facility nbs -info *param_name*. To be honest, I’m not at all familiar with NBS, if EMC support is available to you I’d recommend opening an SR. Sorry I can’t be of more help.

  5. I like the valuable info you provide in your articles.

    I will bookmark your weblog and check again here frequently.
    I’m quite sure I’ll learn a lot of new stuff right here! Best of luck for the next!

  6. Great info — thanks for collecting! Very helpful. One suggestion — to allow people to be able to cut’n’paste, some of the commands were put into uppercase (probably an automatic “correction” by your blog software); for example, “Nas_fs”, “Server_stats”, and “Fs_group” are examples of commands not found (because of the initial capital letter). There are also 3 commands with syntax “..server_config” (two leading dots) instead of “.server_config” (one leading dot). For newbies, might have problem debugging what went wrong, and this is so wonderful I wanted to help you make it “perfect” 🙂

    1. You can use -p in the command if you want to specify tcp, udp, icmp, or ip. It is not a required parameter. Here is the syntax: server_netstat movername [ -A {inet|inet6} ][ -a ][ -i ][ -r ][ -s ] [ -p {tcp|udp|icmp|ip} ]

  7. Is there any command to view the domain controller which Celerra contacts for SID lookups? I am creating home folders by a tool and Celerra doesn’t find the newly created users when setting permissions and throws the error – ‘Error 1337 : Invalid SID structure’. It seems celerra doesn’t find users in the DC it contacts. Can we change the DC preference of Celerra for lookups?

    1. It is possible to see which DC’s are being used by the Celerra. To view the current domain controllers visible on the data mover run this command:
      .server_config server_2 -v “pdc dump”

      That command will show you all of the domain controllers that the Celerra can see. It pulls the info from DNS. A successful connection to a DC will show a ‘Cnx=SUCCESS,DC request succeeded’ in the output. If you want to disable certain DC’s from being used, you can enable or disable a domain controller on the data mover with these commands:
      .server_config server_2 -v “pdc enable=” Enable a domain controller
      .server_config server_2 -v “pdc disable=” Disable a domain controller

      With that said, I don’t believe there is a specific command to change the preference for lookups. That’s just my experience, however, there could be a way I’m not aware of. I’ll do a little research and post again if I find anything. Remember that the .server_config command is undocumented from EMC. If you decide to use it, I would recommend opening an SR before using the above mentioned commands on a production system, test it on a test/dev array first. Use the .server_config command at your own risk!

        1. I don’t have any firsthand experience with the issue you’re having so I can’t say for certain that setting those parameters will help, but on the surface it does look like you’d be ok to do it. I of course don’t work for EMC so you’d need to contact them for assurance that it won’t cause another problem. I read that that changing those parameters will trigger SID-to-Name lookup attempts to the Domain Controller for any orphaned SID detected, which could cause performance problems between the Celerra and the DC, so be warned.

          You can modify those CIFS Parameters using the server_param command:

          # server_param server_2 -facility cifs -modify acl.mappingErrorAction -value 3
          # server_param server_2 -facility cifs -modify acl.retryAuthSid -value 600
          # server_param server_2 -facility cifs -modify acl.FailOnSDRestoreError -value 0

  8. This drove me crazy for a few hours …

    When running the below command you have to ensure that you leave off the initial “/” in the export directory you want to add.

    Ex. server_export server_2 -Protocol nfs -name exports/usr/home/ace /ace/path1

    So in this example I wanted to add /exports/usr/how/ace to the /ace/path1 filesystem. After many attempts I found out that I can not have the initial “/” in the command. I couldn’t find this in any documentation and it was trial and error until I figured it out. Perhaps this is common knowledge but just thought I’d share.

    1. Check the following:

      – The source file system MUST be mounted Read-Only (what’s easier is to create a checkpoint of the FS)
      – The destination file system:
      ….. MUST be the same size or larger than the source file system.
      ….. MUST also be mounted Read Only
      – The ReplicatorV2 license must be enabled for nas_copy to work, that is, nas_license -create replicatorV2.

  9. Hi . this is amazing site. You are doing great job. Wondering if you can help me. What is the command to check on LUN’s through CLI

    1. Thanks. Use nas_disk -list to view the connected LUNs. The fifth column in the output is a dash with a four digit number. This number is a hexadecimal representation of the Clariion/VNX LUN (for example, 021D = LUN 541).

      Sample Output:

      [nasadmin@celerra ~]$ nas_disk -list
      id inuse sizeMB storageID-devID type name servers

        i am actually using virtual VNX through VSA.

        One of my major problems is that all the sudden in Unisphere I no longer can see disks and LUN’s tab under storage

        Not sure how to fix it . Any advice would highly appreciated

        1. Unfortunately I don’t know off the top of my head what would be causing that issue for you. This is one of those times I’d probably open an SR with EMC.

  10. Appreciating the persistence you put into your site and detailed information you offer.

    It’s awesomee to come across a blog every once in a while that isn’t the same old rehashed information.
    Fantastic read! I’ve saved your site and I’m including your RSS feeds to my Google account.

  11. What’s Happening i am new to this, I stumbled upon this I have
    found It absolutely useful and it has helped me out loads.
    I hope to give a contribution & aid different customers like its aided me.
    Great job.

  12. i am trying to delete the alerts and warning on a EMC NS480 i found the commands below but the seem to do nothing. any ideas?

    Clear the archived alert_logs filescp -p /nas/log/webui/alert_log /nas/log/webui/alert_log.1cp -p /nas/log/webui/alert_log /nas/log/webui/alert_log.2cp -p /nas/log/webui/alert_log /nas/log/webui/alert_log.3cp -p /nas/log/webui/alert_log /nas/log/webui/alert_log.4

  13. sorry wrong commands below are the ones i found
