2. what is the step to install a replacement, how does it takes the personality of the failed CS

3. in the san where is the configuration save, that belongs to CS

4. if the hard disk is the root of failed, if i install a new one hd in the CS, how to do a disaster recover restore of DART OS. is it posible?

    Hi Maynor,

    replacement of a control station is done by an EMC or service partner technician.

    They have the necessary tools and procedure (which varies between DART code and models).

    Hello,

    The EMC customer service rep would normaly perform the hardware replacement.I would hope if they are assisting you that they would also be helping you with some instruction. The hardware replacement is pretty straight forward.Not sure if your Control Station is functional or not but there are some files that you may want a backup of.You can copy then off using SCP, Winscp or other methods.Your EMC rep could help you to identify which files they are. You would then simply shutdown the Control station, carefully marking all the cableing before removing. The Control Station then can be removed from the front and the new Control Staion inserted and connected in the reverse order applying the power last.The Nas code CD with the exact version of code, in your case 5.6.40.3 must be inserted in the control station cd/dvd drive to begin the replacement.The script to replace the Control station then can be run by the EMC resource.

    Please understand failure to run the correct replacement script may lead to an outage so care must be taken!

    Thnks Chrisv

    unfortunally, actual CS, is inaccesible, thats the reason of replacement, we have troubles trying to access some filesystem, with errors.

    I want to know if i am unable to access the actual control station and there is no backup of the some files you mentioned

    am i going to see my nas personal configuration intact, after replacements completes

    thanks.

    what do you mean by NAS configuration ..CIFS/NFS ? Control Station can be offline and Celerra will continue to function.

    sure dynamox

    celerra is up and working in a production environment

    i undestand that, but i am unable to configure, add or delete something else

    cause the control station is dead.

    I am awaiting for a replacement.

    what am i trying to explain and ask is, if  the new CS will keep all definitions

    that the failed CS had

    thanks

    i had CS replaced on one of my NS40 a month ago. I had to provide CE with ip/mask/gateway/dns/smtp information so it's either not documented anywhere on EMC side or he did not know how to retrieve that information.  I had a couple of custom scripts in /home/nasadmin and they were gone after replacement so if that's what you mean by definitions then hopefully you have a copy somewhere else.

    The major config like file systems, shares, ... isn’t kept on the control station HDD so it will be recovered and the system config will look like the old.

    There might be some details like control station IP or callhome config that need to be recovered or entered manually during the procedure.

    Also any changes that you have done manually to local files or content in /home/nasadmin will be lost unless you can find a backup.

    If you need the exact procedure than you need to ask the support engineer doing or helping with the replacement for it.

    thanks dynamox

    the thing is more simple,

    am i going to admin the new control station without any diference with the old one.

    and am i going to view all filesystem, cifs servers, datamovers, credentials, etc. as if nothing had happened?

    how do they that?

    what are they going to required from me before adding the CS?

    and what is the step to add this new CS

    i don't have access to CE replacement procedure but i can tell you that you will manage it as if nothing happened.
