Configuring disks on a new system
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.
Disk protection provides more information about the disk protection that is available.
Attention: When
you perform the tasks in this checklist, the system moves large amounts of
data. Make sure that you have completely saved
your system in the event that you need to recover from an error situation.
Before you begin
Print a copy of this checklist. Check off the configuration tasks as you perform them. This checklist provides an important record of your actions. It might help you diagnose any problems that occur.
Most tasks in the checklist include references to other topics. Refer to these topics if you need more information about how to perform a particular task.
| Task | What to do | Where to learn more |
|---|---|---|
| 1.___ | Display your disk configuration. Currently, all of your disk units except the load source disk unit appear as non-configured. | Evaluating the current configuration |
| 2.___ | Use the Add Disk Unit wizard to add non-configured disks to the correct disk pools. You will have the option to start device parity protection or to start compression if disks are available for these actions. | Adding a disk unit or disk pool |
| 3.___ | You can change this to a different storage threshold for any disk pool if required. The default storage threshold for each disk pool is 90%. | Setting the threshold of a disk pool |
| 4.___ | If you chose to create protected disk pools and included pairs of disk units to be mirrored, you might want to restart to the dedicated service tools (DST) mode and start mirroring for those disk pools now. | Starting mirrored protection |
| 5.___ | If you started mirrored protection for the system disk pool or a basic disk pool, wait until your system completely restarts. | |
| 6.___ | Verify that your disk configuration is correct. | Evaluating the current configuration |
| 7.___ | Print your disk configuration to have available in case a recovery situation occurs. | Printing your disk configuration |
