Creating an independent disk pool

Create an independent disk pool.

Start of changeTo create an independent disk pool, you can use the New Disk Pool wizard or the Configure Device ASP (CFGDEVASP) command. These assist you in creating a new disk pool and adding disk units to it. The disk pool wizard and the command can be used 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.End of change

Start of changeThe disk pool wizard and the command can also be used to configure disk encryption. You must set the ASP master key before you can create an encrypted independent disk pool.End of change

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.
