2 x ns120 destination and source site, how Usermappers must be implemented

using best practices in DR plan, i need to configure my 2 ns120 in order to continue without autentication problems

what i need is that now they are conected and in production, I forgot configure the usermappers best practice setup.

i have already configure and using the source site nas, and in the destination site nas, is receiving vmd and FS replicas.

i need to avoid authentication disruption. what are the step to configure both.

do i have to copy user and group file from the source to destination yes or not.

thnks

I depends on your setup and whether your DR site has already done mappings.  usermapper has it's own database - so copying passwd / group files won't help.  I would suggest to work with customer service or professional service on this.  If there are are no mappings on one side you could simply configure usermapper to use the other side as primary   Rainer

if mappings means shares?

No, there are no mappings in the recovery site.

it is just replicating the vdm and its files systems of the primary sites.,

Best practices says that destination site must act as "primary usermapper" and the source must act as "secondary usermapper"

if  i do it now, changing parameters, i am going to have any disrruptions?

thank you

ohh sorry for my confusion

no there are no user mappins in the destination site, and its user and group tables are blank, with no sid-id user maped

but source already has 3 user maped.

When the changes is going to be done, specifying the destination box as "primary user mapper" what the next step?

what  test do i need to do in order to confirmed that everything  is ok.

If you only have 3 users mapped, you may still be able to make this change without having a lot of impact.   You can export both the user and group mappings to files, and import them on the destination side.  When you do this, make the destination side primary, and have primary side point to usermapper at DR side.

The command to import/export usermapper database is as follows:

server_usermapper { | ALL }

           | -Import { -user | -group } [ -force ] pathname
           | -Export { -user | -group }  pathname

Examples:

server_usermapper server_2 -Export -user /tmp/userm_user

server_usermapper server_2 -Export -group /tmp/userm_group

Hope this helps.

I would suggest to start with the usermapping manual to get the concepts
