Resetting controller conguration using RACADM
To reset the controller conguration:
racadm storage resetconfig:<Controller FQDD>
For more information, see the iDRAC RACADM Command Line Reference Guide available at dell.com/idracmanuals.
Switching the controller mode
On PERC 9.1 and later controllers, you can change the personality of the controller by switching the mode from RAID to HBA. The
controller operates similar to a 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. Before you change the mode of the controller from RAID to HBA, ensure that:
• The RAID controller supports the controller mode change. The option to change the controller mode is not available on controllers
where the RAID personality requires a license.
• All virtual disks must be deleted or removed.
• Hot spares must be deleted or removed.
• Foreign congurations must be deleted or cleared.
• All physical disks that are in a failed state, must be removed.
• Any local security key associated with SEDs must be deleted.
• The controller must not have preserved cache.
• You have server control privileges to switch the controller mode.
NOTE
: Ensure that you back up the foreign conguration, security key, virtual disks, and hot spares before you switch the mode
as the data is deleted.
NOTE: Ensure that a CMC license is available for PERC FD33xS and FD33xD storage sleds before you change the controller
mode. For more information on CMC license for the storage sleds, see the Dell Chassis Management Controller Version 1.2 for
PowerEdge FX2/FX2s User's Guide available at dell.com/support/manuals.
Exceptions while switching the controller mode
The following list provides the exceptions while setting the controller mode using the iDRAC interfaces such as web interface, RACADM,
and WS-MAN:
• If the PERC controller is in RAID mode, you must clear any virtual disks, hot spares, foreign congurations, controller keys, or preserved
cache before changing it to HBA mode.
• You cannot congure other RAID operations while setting the controller mode. For example, if the PERC is in RAID mode and you set
the pending value of the PERC to HBA mode, and you try to set the BGI attribute, the pending value is not initiated.
• When you switch the PERC controller from HBA to RAID mode, the drives remain in Non-RAID state and are not automatically set to
Ready state. Additionally, the RAIDEnhancedAutoImportForeignCong attribute is automatically set to Enabled.
The following list provides the exceptions while setting the controller mode using the Server Conguration Prole feature using the WS-
MAN or RACADM interface:
• Server Conguration Prole feature allows you to congure multiple RAID operations along with setting the controller mode. For
example, if the PERC controller is in HBA mode, you can edit the export xml to change the controller mode to RAID, convert drives to
ready and create a virtual disk.
• While changing the mode from RAID to HBA, the RAIDaction pseudo attribute is set to update (default behavior). The attribute runs
and creates a virtual disk which fails. The controller mode is changed, however, the job is completed with errors. To avoid this issue, you
must comment out the RAIDaction attribute in the XML le.
