raid 5 sas replacement


I have a dell poweredge r750 server, with raid 5.
1 sas hdd failed, if I replace the faulty hdd, will the raid rebuild be done automatically or do I have to rebuild it?

You should be able to remove the failed drive, wait 30 seconds, then insert the replacement drive, then a few moments later it should start automatically rebuilding. Now in the case it doesn't automatically start, then you will need to assign that replacement drive as a Global Hotspare and then that should trigger the rebuild. 


Let me know if this helps.

Unfortunately, water got into the connector, which is why the hdd became defective.
If I put the new hdd in another sas connector, can I rebuild the raid or do I have to make a completely new raid block?

if in the other connector the new hard drive is recognized then it should start the rebuild. The position of the hard drive in the controller is not important.
