Hi everyone! I'm helping out with a non-profit server that's running on an older Dell machine with a PERC H310 RAID controller and 8 x 1 TB drives configured in RAID-10. One of the drives showed signs of failing, so I booted into the PERC BIOS Configuration Utility to replace it. The new drive is being rebuilt, but it seems to be taking a long time—after 12 hours, it's only at 12%. The rebuild rate is currently set to 30%, but I read somewhere that it can be adjusted. I'd like to bump it up to at least 75% since there are no users on the server currently. However, to do this, I need to reboot and access the OpenManage Server Administrator or iDRAC7. My question is: is it safe to reboot the server while the rebuild is in progress? And what reboot option should I choose from the following: Power Off System, NMI, Graceful Shutdown, Reset System, or Power Cycle System? Any advice would be greatly appreciated!

I see your point, but you can safely reboot to adjust the rebuild rate if there aren't any users currently on the server. Just keep in mind that the rebuild might not speed up drastically by increasing that percentage. It’s designed to prioritize reliable operations, so it might be worthwhile to let it cook a bit longer. Just choose 'Graceful Shutdown' for the least risk.
I’d recommend letting the rebuild finish before rebooting. Interrupting it can lead to serious issues, and it might take a while, but patience is key here. The rebuild rate is set to a lower percentage to avoid impacting users; raising it to 75% could affect performance if you had users onboard, so it’s best to just wait this one out.
