How to add a new storage array to NAS Gateway (NS40G)

Hi,

How do I add a new storage array (CX4-480) to an existing NS40G which already has a CX as its main storage?

Thanks,

    Hi Triet,

    Welcome to the EMC Support Forums.

    I suspect, you need to engage your local EMC Support team (Customer support engineer) for helping you out here. There is a certain procedure to follow to add the second CLARiiON storage and more importantly the EMC Install Base needs to be updated, if you add the second CLARiiON to the NS40G Gateway.

    There is a script (/nas/sbin/add_clariion) which can be used to do this - the script can take care of the Zoning on the FC Switches and Creation of RAID Group and LUNs on the new CX4. However, the zoning and the CLARiiON Configuration can be done manually as well. Once the second CLARiiON is added - you can configure the new disks following the steps mentioned in the Celerra Tools section in the Powerlink -

    http://corpusweb130.corp.emc.com/ns/common/post_install/Config_storage_gatway.htm

    I 'll personally prefer to engage EMC personnel - as this may lead to some unwanted issues with the CAM table or SCSI device list or the NASDB.

    Thanks,
    Sandip

    the script will actually creates the zones for you ? That's a scary thought considering you could have multiple vsans, IRV ..etc

    The script is capable of doing the zoning provided you feed all the required information - however, you can manually zone as well which I prefer for any complex and large fabric.

    Thank you all for replying so quickly.  It was only after I post that I saw another thread called "Add CX4-120 Storage to an Existing NS502G" which seems to answers a lot of my questions.  It was on the right hand side under "More Like This".  I was using the search option, but posting seems to yield a more fruitful results.

    I will now attempt to manually zone (using Best practice of course) and rescan and see what happens.  Will report back.

    Thanks,

    OK.  I've done zoning.  Now i'm stuck at running the /nas/sbin/add_clariion.

    # /nas/sbin/add_clariion
    usage:  /nas/sbin/add_clariion
                     -init [ -kickstart filename ]
    # /nas/sbin/add_clariion -init

    CRITICAL FAULT:
            Error: unable to acquire storage lock, try later

    What do I need to do here?

    Thanks,

    -Triet

    Hi,

    This error may be caused because of many reasons, I think this Primus emc158431 would help you to resolve the issue.

    Let me know if this helped you to get out this error.

    This may be for many reasons - if you continue to get the message, you may need to open a support case or contact your local EMC personnel.

    Also, as I mentioned earlier, adding a second CLARiiON Box is typically NOT a customer activitiy - which needs to be done by an authorized and trained personnel. The process needs to be followed properly, So please engage your local EMC team if not already done. Or else, this may lead to support issues in future.

    Please keep in mind that the backend device configuration may create significant problems if proper steps and precautions are not followed.

    Thanks,
    Sandip

    Success.  Finally fixed.  It was so simple.  The error is due to "su -" instead of just plain "su" when invoking the /nas/sbin/add_clariion command.  That was it.

    Thanks for all the responses.

    We did some net new installs (In a training class) using the automated method and letting the script create zoning etc. it really did work quite well.  I dont really know of many customer environments where they would trust it (the script) and allow it to do such (you do provide the login/password for the switches).  We also did some installs the standard way of creating zoning prior too the install.

    Robert,

    I completely agree.  I don't like the idea of the script creating zones.  I was in a tight spot and had to get this up and running pretty quickly.  After the script, I went back and manually deleted the script-generated zones since I already created my own cusomized zonings.  I wish there was a way to bypass the zoning part.

    Thanks,
