Creating an independent disk pool

Create an independent disk pool.

To create an independent disk pool, you can use the New Disk Pool wizard. This will assist you in creating a new disk pool and adding disk units to it. The disk pool wizard allows you to include unconfigured disk units in a parity set, and start device parity protection and disk compression. As you add disk units, do not spread disk units that are in same parity set across multiple disk pools, because failure to one parity set would affect multiple disk pools.

The disk pool wizard also allows you to configure disk encryption. You must set the ASP master key before you can create an encrypted independent disk pool.

To use the disk pool wizard to create an independent disk pool using IBM® Systems Director Navigator for i5/OS, follow these steps:

Select Configuration and Service from your IBM Systems Director Navigator for i5/OS window.
Select Disk Pools.
From the Select Actions menu, select New Disk Pool.
Follow the wizard's instructions to add disk units to a new disk pool. Select Primary or Secondary for the type of disk pool.
Print your disk configuration to have available in case of a recovery situation.
Record the relationship between the independent disk pool name and number.

To use the disk pool wizard to create an independent disk pool using System i® Navigator, follow these steps:

In System i Navigator, expand My Connections (or your active environment).
Expand the System i you want to examine,Configuration and Service > Hardware > Disk Units.
Right-click Disk Pools and select New Disk Pool.
Follow the wizard's instructions to add disk units to a new disk pool. Select Primary or Secondary for the type of disk pool.
Print your disk configuration to have available in case of a recovery situation.
Record the relationship between the independent disk pool name and number.

Note: Add independent disk pools when your system is fully restarted. If you must use the disk pool wizard in the dedicated service tools (DST) mode, you need to create an associated device description for the independent disk pool when the system is fully restarted. Use the Create Device Description (ASP) (CRTDEVASP) command to create the device description. Name the device description and resource name the same as you name the independent disk pool. You can use the Work with Device Descriptions (WRKDEVD) command to verify that the device description and independent disk pool name match.
