DEFAULTS Restores the system to its default configuration.
This command is used to restore the system to its default configuration. The system will halt all I/O requests, delete all the LUNs, and restore all the parameters back to their defaults values. This is a destructive operation which will delete all the data stored in the system. The system will then ask if it should erase all the configuration information stored on the disks. This will prevent the system from retrieving the backup copies of the configuration settings from the disks after the system is restarted. This means that to read the parameter blocks off the disk, the current controller will have to be removed and replaced by another system. After the defaults have been loaded, the system will ask if it should begin reconfiguring by scanning for the disks. New LUNs can be created after the disks have been added back to the system.
The following table outlines the combinations of answers to the defaults questions and shows what the outcome will be for each combination:
| Erase Configuration | Disk Scan | Outcome |
|---|---|---|
| Y | Y | IP address saved NVRAM cleared. Disk information is cleared. S2A remains powered up. Disk scan occurs. IP address is restored. |
| Y | N | IP address cleared NVRAM cleared. Disk information is cleared. S2A remains powered up. |
| N | N/A | IP address cleared, NVRAM cleared. Disk information is preserved. S2A powers down. |
| Y | Y | IP address saved, NVRAM cleared. Disk information is cleared. S2A remains powered up. Disk scan occurs. IP address is restored. |
| Y | N | IP address cleared, NVRAM cleared. Disk information is cleared. S2A remains powered up. |
| N | N/A | IP address cleared, NVRAM cleared. Disk information is preserved. S2A powers down. |
