Yazoo,
Things done before we move any data out of the old DRM pool.
Define new tape library to the SP Server.
Make sure that the SP Server is able to communicate with the new library .
ie:
backup db devclass=devclassname_new_library type=full
Define new DRM storage pool.
Update the "prepare" to use the new tape library.
Update the recovery plan with the new tape library and any information that need to be updated.
1. Update the DRM to use the new DRM tape pool.
When the next schedule "
prepare" runs, the data should be going to the new DRM pool.
NOTE: During this time part of the data will be in the old DRM pool.
Over time all the data in the old library will expire.
When all the data have expire in the old DRM pool, then remove the old DRM storage pool and the old library.
Primary pool -> Stop data being copy to -> Old DRM pool
Primary pool -> Start data being copy to -> New DRM Pool
... move the data as quickly as possible.
Then this option you may not want to do.
2. Migrate all the data from the old DRM pool to the new DRM pool.
Bring back ALL the DRM tapes from the vault location.
Check in ALL the DRM tapes into the old library, update the volume access to "readonly".
On the old DRM tape pool update the "next pool" to point to the new DRM tape pool.
Then issue "
MIGrate STGpool pool_name LOmig=90".
Once the process complete, rerun the "mig stg" command with lo=80, repeat the process until we
reach zero (0)
Be sure that there are plenty of scratch tapes in the new tape library.
Primary pool -> Stop Data being copy to -> Old DRM Pool -> Migrate data to -> New DRM Pool
Primary pool -> Start data being copy to -> New DRM Pool
3. Delete ALL the DRM volumes in the old tape library.
NOTE: This will leave you vulnerable if a disaster happen during this period.
When we run DRM process, all the data will be backed up to the new DRM stgpool.
Be sure that there are plenty of scratch tapes in the new tape library.
Delete ALL DRM volumes in the old DRM pool
Primary pool -> Start data being copy to -> New DRM Pool
Good Luck,
Sias
