Reconfiguring an LCU with larger capacity 3390 volumes

Complete this task to reconfigure an LCU with larger capacity 3390 volumes.

To retain your data, you must offload the data from the address range of the ranks to be reformatted by performing the following steps:

  1. Confirm the raid ranks that are associated with the address range that is being modified.
  2. Vary the address range offline. This causes any associated parallel access volumes (PAVs) to become unbound.
  3. Issue Devserv (DS QP,xxxx,nnnn) using the alias addresses to confirm aliases are unbound.
  4. Undefine the raid rank to allow the configuration of larger capacity volumes.
  5. Reassociate the PAVs.
  6. Vary the base address range online.
  7. Issue Devserv (DS QP,xxxx,nnnn) using the base addresses to confirm that the aliases are bound.
  8. Restore the data that you offloaded.
