Hi All,
We had client use EMC NAS Celerra in two seperate location. The client using TSM on both site for backup with NDMP. Now the client want perform DR for both site, that is to restore data to the Celerra from one site to another.
What we have do were:
1. Restore the TSM DB from site A into TSM server of site B.
2. Setup the TSM server at site B so that it can read the tape from Site A.
3. Now the TSM at site B contains the TSM instance from Site A, then we configure NDMP setting for that TSM instance.
4. Query toc for tapes from Site A were ok.
5. Then we try to perform restore node with below command
restore node celerra /root_vdm_1/nas001 /root_vdm_2/nas002
where
celerra was the NAS node name, same for both sites
/root_vdm_1/nas001 was the mount on Celerra at site A,
/root_vdm_2/nas002 was the mount on Celerra at site B for restore.
The result was failed with below error:
ANR2020E RESTORE NODE: Invalid parameter - /root_vdm_2/nas002
It seems that the TSM instance at site B does not recognize /root_vdm_2/nas002 as the valid mount. That may due to the fact that TSM server at site A does not have information about /root_vdm_2/nas002, so do the DR instance at site B.
Does anyone had experiences on NAS DR with TSM? Should we create the node name on Celerra at site B in order to perform the restore?
