How to remove unused storage pool from volume correctly.

Hi,

my XSAN volume's layout is this:

MyVolume
--- DATA_POOL_A
-- LUN_A1
-- LUN_A2

--- DATA_POOL_B
-- LUN_B1
-- LUN_B2

--- METADATA_POOL
-- LUN_MD1
-- LUN_MD2

All storage pools have data with affinities.

I added new chassis (with 2 LUNS: LUN_NEW_B1, LUN_NEW_B2):

MyVolume
--- DATA_POOL_A
-- LUN_A1
-- LUN_A2

--- DATA_POOL_B
-- LUN_B1
-- LUN_B2

--- NEW_DATA_POOL_B
-- LUN_NEW_B1
-- LUN_NEW_B2

--- METADATA_POOL
-- LUN_MD1
-- LUN_MD2

I emptied DATA_POOL_B and I need to remove (forever) DATA_POOL_B from MyVolume.

So my final volume layout will be:

MyVolume
--- DATA_POOL_A
-- LUN_A1
-- LUN_A2

--- NEW_DATA_POOL_B
-- LUN_NEW_B1
-- LUN_NEW_B2

--- METADATA_POOL
-- LUN_MD1
-- LUN_MD2

How to do it correctly ?

Thank you.

Peter

believe it or not, you can't actually remove a storage pool. but you can mark a stripe group (pool) down. by doing this, you will achieve what you want.
