Disk protection checklists

 

There are checklists that you can use for disk protection tasks.

• Adding a new IOA
  This checklist shows the sequence of tasks that you use to add a new IOA and new disk units to your system.

• Adding disk units to an existing IOA
  This checklist shows the sequence of tasks that you use to add one or more disks to an existing IOA that has built-in device parity protection.

• Removing disk units that have device parity protection from a disk pool without mirrored protection
  This checklist shows the sequence of tasks that you use to remove one or more disk units from an IOA with built-in device parity protection.

• Removing disk units that have device parity protection from a disk pool with mirrored protection
  This checklist shows the sequence of tasks that you use to remove one or more disk units from an IOA that is capable of device parity protection.

• Upgrading the load source disk unit with device parity protection
  This checklist shows the sequence of tasks to upgrade your load source disk unit (unit 1) with a disk unit that has at least a 17-GB capacity while keeping device parity active. The disk units that are replaced in this procedure are discarded.

• Adding disk units without disk protection
  This checklist shows the sequence of tasks that you use to configure disks on a new system. Whether you need to perform all the tasks depends on the disk protection that you want on your system.

• Moving disk units between mirrored disk pools
  This checklist shows the sequence of tasks that you use to move one or more disk units from one basic disk pool to another basic disk pool.

• Upgrading the load source disk unit with local mirroring using non-configured disk units
  This checklist shows the sequence of tasks to upgrade your load source disk unit (unit 1) and the mirrored load source with disk units that have equal capacity, are at least 17-GB, and are mirror protected. The disk units that are replaced in this procedure are discarded.

• Upgrading the load source disk unit with local mirroring using newly installed disk units
  This checklist shows the sequence of tasks to upgrade your load source disk unit (unit 1) and the mirrored load source with disk units that have equal capacity, are at least 17-GB, and are mirror protected. The disk units that are replaced in this procedure are discarded.
