Resetting controller configuration
You can reset the configuration for a controller. This operation deletes virtual disk drives and unassigns all hot spares on the
controller. It does not erase any data other than removing the disks from the configuration. Reset configuration also does not
remove any foreign configurations. The real-time support of this feature is available only in PERC 9.1 firmware. Reset
configuration does not erase any data. You may recreate the exact same configuration without an initialize operation which may
result in the data being recovered. You must have server control privilege.
NOTE:
Resetting the controller configuration does not remove a foreign configuration. To remove a foreign configuration,
perform clear configuration operation.

Switching the controller mode
On PERC 9.1 controllers, you can change the personality of the controller by switching the mode from RAID to HBA. The
controller operates similar to an HBA controller where the drivers are passed through the operating system. The controller mode
change is a staged operation and does not occur in real time.
PERC 10 and later controllers supports Enhanced HBA mode, replacing HBA from the current controller mode options. However,
PERC 9 still continues to support the HBA mode.
NOTE:
● Enhanced HBA supports Non-RAID PDs and all RAID level VDs.
