By using DRM concept we can perform the tape moment from on-site to off-site and vice-versa. The main advantage of DRM is we can recover the complete TSM server if any disaster occurs.
In DRM concept we will be moving copy tapes and TSM DB backup tapes from on-site to off-site.and we have to move scratch tapes and copy tapes from off-site to on-site as per the requirement.
PROCEDURE TO IMPLEMENT DRM:
1) We needs to check the DRM parameter by using the below command
Q drmstatus
2) Once we get the DRM status we need to set the DRM parameters by using below commands.
3) We need to set the DRM recovery plan prefix by using below command
Set drmplanprefix “location”
DRM plan prefix specifies location of the plan file. The plan file contains complete TSM Server configuration information. If any disaster happens we can recover the TSM Server by using this plan file.
This plan file will be generated by running “prepare” command in TSM Server.
4) We need to set DRM Primary storage pool name by using below command.
Set drmprimstgpool stgpoolname
5) We need to set DRM copy storage pool name by using below command.
Set drmcopystgpool copystgpoolname
6) We need to set the DRM courier name by using below command.
Set drmcouriername couriername
7) We need to set the DRM vault name by using below command.
Set drmvaultname vaultname
8) We need to set the DRM notmountable name as notmountable.
Set drmnotmountablename notmountable
9) We need to set DRM DB Backup expire days by using below command.
Set drmdbbackupexpiredays no. of days
10) We need to set DRM Recovery Plan Prefix Expire days by using below command.
set drmrppexpiredays no. of days
