Power Edge R310 Update firmware PERC S300

Hi everyone.

I have 3 PowerEdge R310 operating with 3 HDD / RAID5  on PERC S300.
If i try  updating PERC firmware (SAS-RAID_Firmware_RPCKX_WN32_2.0.0-016600193000_A06) whilst the server is online, the RAID and SO restarted intact?

I apreciate your answers.

Thanks.
