Solution:


Starting Enginuity 5875, Virtual LUN VP mobility feature can be used to move thin devices, metadevices between the pools.

This is Online Process and allows thin device data to be migrated between high-performance drives and high-capacity drives. Data can be moved between storage pools configured on different drive technologies, and with different RAID protection types.

 

You can follow the below given steps for migrating a group of thin devices contained in VP_ProdApp1 storage group, currently bound to a RAID 6 (14+2) on SATA thin pool, to a RAID 1 on FC thin pool (FC_R1_VP) :

 

1. Validate the migration:

 

  symmigrate –sid xxx –sg VP_ProdApp1 –tgt_pool –pool FC_R1_VP –name VP_migration validate

 

2. Establish the migration:

 

  symmigrate –sid xxx –sg VP_ProdApp1 –tgt_pool –pool FC_R1_VP –name VP_migration establish


3. Monitor the migration progress:

 

  symmigrate –sid xxx –name VP_migration query


4. Verify the migration has completed:

 

  symmigrate –name VP_migration verify –migrated

 

5. Terminate the migration:

 

  symmigrate –name VP_migration terminate
