Moving EMC CX-700 DATAMOVER data to new EMC VNX DATAMOVER.

[kevlee]

Hi,
Current NDMP setup:-
EMC cx-700 (3 active datamovers) - all tape aux ports connected to SAN.
IBM3584 tape library (drives connected to same SAN)
NDMP backups set up using normal method (i.e Client Node, Datamover(specifying IP address of datamover, TCP/IP port, user name,etc)), TSM storage path specifying tape device e.g c128t0l0.

We are migrating data to new EMC VNX again with datamover tape ports connected to same SAN so that we can continue perform backups/restores.

Is it a simple case of Changing the IP address of the TSM DATAMOVER setting to the new VNX datamover IP address (after configuring the actual new datamover for NDMP) ??. How do we determine which tape devices picked up by EMC Datamover match the actual TSM tape drives so that each NDMP tape path can be updated correctly to start tape activity for the new VNX datamover's??

Has anyone gone through this procedure before?? any advice would be appreciated. Thanks.

1) You will need to zone aux ports on the VNX to the tape library
2) You will need to discover tape drives on VNX

server_devconfig server_2 -create -scsi -all (discovers new devices)
server_devconfig server_2 -list -scsi -nondisks -all (will list tape drives)
3) create ndmp username on VNX

To create an account by using the MD5 encryption method, type:

# /nas/sbin/server_user server_2 -add -md5 -password user_name
Repeat for each Data Mover.
4) at this point you can update TSM configuration and point it to VNX datamover IP address (not Control Station

As far as figuring out which tape drive corresponds to whitch ctl number on VNX, look at this thread

Sounds reasonably straightforward. Thanks very much for the info, appreciate it.
