As you have RAID 5 you will be able to replace the data with out data lost. You can refer below link for details on replacing the drive. You need to ensure new drive is from same family and type of current drive with same or higher capacity than current one. In your case you need to use SATA HDD. [URL]  In summary as the current drive is failed you can remove and replace with new drive. Once replaces wait for rebuild to start. If rebuild is not started within 2 to 3 minutes assign the drive as hot spare for rebuild to initiate.  There will be performance impact on the virtual disk during rebuild. So It is recommended to shutdown the server while rebuilding. It is good practice and recommended to backup your data before carrying out any such maintenance tasks to handle any unforeseen behavior.
Hello, Good day!  I just recently got this error after upgrading the VD by installing a new PD on drive 4-7. I guess my question is what are the pre-requisites that I need to do before pulling out the disk and reseating? Will there be any data loss? And can I do it in a live system? Or do I need to shutdown the server first?    [IMAGE]   Raid configuration is RAID5. And I have no hot spare configured. [IMAGE] Thank you in advance.
