mapRebuildDatabase
Occasionally, it may be necessary to eliminate the Persistent Device Map
database entirely, allowing the existing devices to have new addresses assigned.
The mapRebuildDatabase command deletes the current database. When the
ADIC Gateway is next booted, the devices found will be assigned new addresses.
When you run this command you will be given the option of also clearing the VPS
access settings. Because devices will be assigned new addresses, clearing the
VPS database ensures that hosts will not have access to the wrong LUNs.
Accepting this option requires that the system administrator must reassign VPS
access permissions between the hosts and LUNs.

- Show the Map Database
- Show currently attached devices
- Remove unatached devices from database
Attention: Clearing the map database will cause device addresses to
change unpredictably. Use this command only when no host systems
are expecting devices to remain at their current addresses. The ADIC
Gateway must be rebooted after executing this command.
