Move existing CIFS Share between CIFS Servers on Celerra

Hello All,

I have been working on a migration from Windows shares onto Celerra CIFS Shares,

However I have a small problem. Due to typo error in a migration document 3 of the windows shares have been migrated to the wrong CIFS shares on the Celerra.

\\CIFS1\Share1 2 & 3 should have been \\CIFS2\Share1 2 &3

All the data has been migrated and the system is live, however I need to move these CIFS Share from CIFS1 to CIFS2 on the Celerra. Both of these CIFS servers are on the same data_mover Server_2.

Any Advise on limiting the impact on the production enviroment.

Thanks

    are these individual file systems or just directories on the same file system ?  If these are individual file systems you could simply unmount them from CIFS1 and mount them to CIFS2 if they are directories ..the easiest method you could copy them with emcopy/robocopy to another file system.

    i would use host based tools like emcopy/robocopy and copy them over.  If both CIFS1 and CIFS2 are joined to the same AD domain, emcopy/robocopy will preserve NTFS ACLs. There are also other tools like NDMP copy but i find host based tools easier to use.

    They are directories on \\CFIS1 which should have been created on \\CIFS2 which are on the same data mover.

    Thanks

    Hi,

    if I understood correctly, you have more than one CIFS server on the same Data Mover, and some shares were incorrectly set to an specific CIFS server ( -netbios option on the server_export command ).

    If this is the case, you can simply edit the CIFS share properties and uncheck the incorrect CIFS server, then check the box for the correct one.

    Keep in mind if user are connected using the 'incorrect' CIFS server they will loose access.

    It really depends if only the share is wrong or if the data needs to be moved as well (different file system or different structure)

    If that is the case you need to use your host side copy again to correct it

    CIFS Server that should have been created:

    \\CIFS1 on Server_2 with a number of shares

    \\CIFS2 on Server_2 with a number of shares

    A number of shares had been created on \\CIFS1 for the migration, but due to a typo error in the documentation 3 shares should have been created on \\CIFS2

    All the data was migrated using EMCopy all worked well.

    However after running some testing, it was spoted that 3 of the shares that had been migrated, where on the wrong CIFS Server.

    So I need to make sure those 3 shares are moved onto the correct CIFS server, with all data in place and minmal impact to the customer. All this will take place on the same Celerra.

    Thanks

    CIFS1 has its own file system and CIFS2 has its own file system ?  If that's the case use emcopy to "pre-copy" the data mover and than on the date of cut-over, disconnect people from shares being migrated, run final emcopy and remove shares from CIFS1 and create them on CIFS2.
