I'm shopping for a new server and have been using software RAIDs.
But I wondered about doing recovery on a hardware RAID vs a software one. I know with a software RAID you have to enter a series of commands to get the replacement drive working back in the RAID so it can re-sync.
What has to be done in a hardware RAID after you replace the failed hard drive? Is it easier and less time consuming than for a software RAID?
1Easier depends on what type of failure you have with either one. On hardware raid you replace the drive and the raid controller will rebuild automatically in most cases, sometimes you have to trigger the rebuild process yourself using the raid firmware/software – Moab – 2016-03-21T03:23:41.127
With a hardware RAID, how is the trigger to rebuild done? Using regular CentOS commands or are these commands that communicate with the firmware for the hardware RAID? – Edward_178118 – 2016-03-21T04:45:34.923
1Hardware raid is either controlled by software you install in the OS or via directly the raid controllers firmware which can be edited during bios post by using a certain keystroke to enter the firmware utility before windows begins to load. – Moab – 2016-03-21T18:32:08.373
