We have 7 physical drives (6 RAID 10, 1 hot spare) attached to an LSI SAS2008 controller.
Recently a drive failed and the hot spare took over. When the new drive landed I just replaced the failed drive with the new one and that took over as the hot spare.
I then downloaded the LSI RAID Web Console 2 and noticed another 2 drives reporting a predictive failures. The book of words for the web console is for a different, older, version and hours of Google searches have not returned a definitive answer.
I am making an assumption that the correct procedure is to right click the drive in the console and select 'Make offline' - wait for it to spin down and replace it. If so will it start building to the hot spare again and the new drive takes over as hot spare?
