If selected, you must acknowledge your understanding of the risks associated with RAID 5 before continuing. For more information about the supported drive types and available RAID levels, see Chapter 2, “IBM DS8880 hardware components and architecture” on page 25.

## Manually assigning arrays to existing pools 

The storage administrator can manually unassign arrays or reassign assigned arrays to existing pools when the current configuration needs to be modified, such as when the administrator adds storage capacity. To manually assign arrays, complete these steps: 

1. Select an array and click Assign  or Reassign , as shown in Figure 11-45 on page 313. This action opens the Assign Array window. 

2. Select the target pool from the drop-down list, and the RAID level that you want. 

3. Select the Redistribute  check box to redistribute all existing volumes across the pool, including the new array. 

4. Click Assign . 

Note:  In a pool that is managed by Easy Tier, redistributing volumes across the pool is automatic. This redistribution is called Dynamic Pool Reconfiguration . For more information, see IBM DS8000 Easy Tier (for DS8880 R8.5 or later) , REDP-4667.
