This checklist shows the sequence of tasks that you use to add a new input/output adapter (IOA) and new disk units to your system. Use this checklist if you plan to protect some or all of the new disks with device parity protection. You can use this procedure whether you have mirrored protection on your system because you start device parity protection before you add the disk units to a disk pool. If you do have mirrored protection and you are adding disks that do not have device parity protection, you must add them in pairs that have equal capacities.
Print a copy of this checklist. Check off the configuration tasks as you or the service representative perform them. This checklist provides an important record of your actions. It may help you diagnose any problems that occur.
| Task | What to do | Where to learn more |
|---|---|---|
| 1.___ | Install the new input/output adapter in the server. This is normally done by a service representative. | Evaluate the current configuration |
| 2.___ | Physically attach disk units to the new IOA using the Install Disk Unit wizard, which you can access from the Disk Units Graphical View window. | Evaluate the current configuration |
| 3.___ | Use the Add Disk Unit wizard to add nonconfigured disks to the correct disk pools. Use the option to start device parity protection. | Add a disk unit or disk pool |
| 4.___ | If you want a different storage threshold for any disk pool, change it. The default storage threshold for each disk pool is 90%. | Set the threshold of a disk pool |
| 5.___ | You may want to restart to the dedicated service tools (DST) mode in order for the device parity protection to take effect. | Work with device parity protection |
| 6.___ | Wait until your system completely restarts. | |
| 7.___ | Verify that your disk configuration is correct. | Evaluate the current configuration |
| 8.___ | Print your disk configuration to have available in case a recovery situation occurs. | Print your disk configuration |
