Selecting pool volumes

You can select a pool-VOL to add when creating pools. The selected pool-VOL’s information is used to calculate Total Selected Pool Volumes and Total Selected Capacity in the Create Pools window.

1. In the Explorer pane, click Storage Systems, expand the storage system tree, and then click Pools.
2. In the Pools window, select Create Pools.
   
   
   
3. In the Create Pools window of the Create Pools wizard, in the Pool Volume Selection section, click Select Pool VOLs.
   
   
   
4. In the Select Pool VOLs window, from the Available Pool Volumes table, select the pool-VOL you want to add to the pool, and then click Add.
   The pool-VOL is added to the Selected Pool Volumes table. You can add a maximum of 1,024 volumes in a pool.

   Note: Before you add an LDEV belonging to a parity group which has the accelerated compression setting enabled, see the information about whether accelerated compression can be enabled in the Provisioning Guide for Open Systems.

   Note: Note the following when you add an external volume:

   • External volumes with cache mode enabled and external volumes with cache mode disabled cannot be contained in the same pool.
   • External volumes with cache mode disabled and internal volumes cannot be contained in the same pool.
   • When setting the tier rank of an external volume to a value other than Middle, select the tier rank from External LDEV Tier Rank, and then click Add.

   Note:

   • To specify conditions to display pool volumes, click Filter to open the menu, specify the filtering conditions, and then click Apply.
   • To select all pool-VOLs in the table, click Select All Pages. To cancel the selection, click Select All Pages again.
   • To specify the unit or the number of rows to be displayed, click Options.
5. Click OK.
