Pinned topic Rationale Clearcase version v7.0.0

‏2013-09-02T13:35:39Z |

Hi everyone,

We are in process of shifting the clearcase installed server from one place to another. During this server movement, we need to understand the impact for the clearcase tool in this server,

What happens to the licensing factors? This is just a physical location change.

Kindly help me answering this. it would be really helpful for us.

    Hi,

    This is a unix server in which clearcase installed . This is a VOB server.

    There is no domain change after this server movement.

    This is just a movement of server from one building to another  and hence there is no change in host name.

     

    If it's just moving to a different building and connectivity to the clients and other resources (for example NAS, NIS, registry, license) are not negatively affected you may not have any change at all. You should certainly test it of course ... if you are moving to a different subnet you can always run into a situation where packets are suddenly dropping due to a switch that's configured differently another one that worked fine for ClearCase.

    You haven't really given any details on what is involved in your migration, or what exact questions you have. What kind of server? vob / view / web / registry / license / other? What OS? Is it part of a domain, and if so is the domain changing? Are you moving it closer or further away from the clients?

    If you need some detailed guidance, please do open a PMR so the support team can assist.

    Hi Benray,

    Thanks for your information.

    I have few more doubts whether there is a possibility of application configured using IP address.

    Do we have any IP dependency in any parameters like licenses,registry etc.

    That depends on your configuration. Licenses would be tied to MAC address generally although I don't know what OS or license type you have -- but it should not be related to ip address. If you use ip address rather than hostname for your clients to get licenses then yes changing ip will have an effect. Same with your registry server. Most people use hostnames so this is not an issue. If your vobs/views are registered / tagged using ip rather than hostname you'll need to reregister / retag them. But again this is not common ... most are using hostnames for this.

    Hi Benray,

    Thanks and I do have another query related to data(VOBS) that are present in the SAN disk.

    Will you please help us understand how to move the files to another SAN?

    Can we consider this as a ordinaty data file/ any specific method to be followed?

    In some senses yes you can treat vob storage as ordinary files. However you take the same considerations as you would in backing up the data, for example the requirements listed here

    http://pic.dhe.ibm.com/infocenter/cchelp/v8r0m0/index.jsp?topic=%2Fcom.ibm.rational.clearcase.cc_admin.doc%2Ftopics%2Fc_backup.htm

    If you are just moving same between same architecture servers and the SANs are seen as local disks you can follow this process

    http://pic.dhe.ibm.com/infocenter/cchelp/v8r0m0/index.jsp?topic=%2Fcom.ibm.rational.clearcase.cc_admin.doc%2Ftopics%2Ft_mvvob_ux_1arch.htm

    If you are keeping the same server and _only_ moving the storage it would be even easier. Just lock the vob, stop Clearcase, tar + gzip the vob storage in such a way as to preserve the ACLs, unzip in the new location, move or rename the old storage directory (in case any clients have that storage path cached this will ensure they don't accidentally touch the old one before you remove it), bring clearcase up and reregister/retag the vob. describe the vob to make sure it is working.

    Hi Benray,

    Your inputs are really knowledgable.

    We are moving the VOBS from one storage to another storage and the Unix server where the application installed still remains the same.

    http://pic.dhe.ibm.com/infocenter/cchelp/v8r0m0/index.jsp?topic=%2Fcom.ibm.rational.clearcase.cc_admin.doc%2Ftopics%2Ft_mvvob_ux_1arch.htm

    Having few queries on what will happen when we perform the reregister/retag the vob.

    Also the question is if the vobs are copied from one to another storage. There should not be any change in Clearcase server.

    Thanks a lot!!!!

    The only change to the procedure you've referenced in the case where the server is the same is you should _unregister/rmtag_ before stopping ClearCase. Then after you have moved the vob storage to the new location you will register/mktag.
