Data cannot be moved from one copy pool to another; this is a design
feature of TSM. However, there is a workaround.







1. Move MOVED_NODE's data from NORM_TAPEPOOL to DR_TAPEPOOL by running

MOVE NODEDATA MOVED_NODE FROMSTG=NORM_TAPEPOOL TOSTG=DR_TAPEPOOL

2. Run

BACKUP STG DR_TAPEPOOL DR_COPYPOOL

This will copy all data in DR_TAPEPOOL to DR_COPYPOOL, including
MOVED_NODE. 

MOVED_NODE's data in NORM_COPYPOOL will then be collected onto a single
tape.

3. Deny access to all volumes belonging to NORM_COPYPOOL and residing in
the tape library by running

UPDATE VOLUME * ACCESS=READONLY WHERESTG=NORM_COPYPOOL
WHEREACC=READW

This will force step #4's action onto a new empty tape volume.

4. Run 

MOVE NODEDATA MOVED_NODE FROMSTG=NORM_COPYPOOL

When finished, all of MOVED_NODE's data in NORM_COPYPOOL will reside on
their own tape volume. Make a note of this new volume's number (tape
000324, for example).

5. Correct the access statuses changed in step #3 command above by
running

UPDATE VOLUME * ACCESS=READWRITE WHERESTG=NORM_COPYPOOL
WHEREACC=READONLY

6. Now delete MOVED_NODE's data from NORM_COPYPOOL by running

DEL VOLUME 000324 DISCARDDATA=YES

You now have all of MOVED_NODE's data in DR_TAPEPOOL and DR_COPYPOOL. If
you're naturally paranoid (like myself) you won't perform step #6 until
all tapes belonging to DR_COPYPOOL are residing in your vault.

Move NodeData and copypools

[Cory Heikel]

I have 2 copypools, one for high priority DR required nodes, and the
other for everything else. The DR copypool is collocated. Every month or
so, I get a request to move a node into the DR pools. I can use the move
nodedata command to move things between the non-copypools, but I need to
find a way to move data between the two copypools. If I can't get the
data moved for a node from the "regular" copypool into the "dr" copypool
then I have to take about 500 extra tapes when we do our dr testing, and
the multitude of tape mounts required for recovery really slows the
process down.

Does anyone have any idea how this could be accomplished?

Thanks in advance!
