Hi all...
I am an IT Technician, and have never dealt with RAID issues before, and would appreciate advice going forward.
I have taken over the maintaining of IT equipment for a company, as the previous IT company was doing the bare minimum to keep the infrastructre afloat.
Upon arriving at the place, and inspecting their equipment, there was an ethernet cable running in the air across a room from one room through to the other, which someone had to tape out the way, drivers missing on the desktops, and a server running Server 2012, which was missing a lot of security updates.
Upon inspection of the server, I realised that it is in a RAID type configuration, with 2 2TB Drives mirroring each other, as there's only one drive showing, at start up the server gets a warning saying the health of the array is in critical status.
The server still works fine, and I upgraded it to server 2019, but now want to tackle this issue with urgency.
HD Senteniel only gives me limited information.
The one 2TB hard drive in the array, reports 75% health, along with the messsage saying
"The hard disk controller provides only a generic self-monitoring (S.M.A.R.T.) status, without additional details.
The S.M.A.R.T. status is: Good" - I cannot see if there are bad sectors or anything.
The second drive is even more vague with the message "
The status of the hard disk is unknown.
This RAID array does not provide access to disk details in the array. Anyway, it can be tested for problems by Disk -> Surface test function."
This server has vital information on it, and this needs to be tackled to prevent the risk of data loss.
Having never dealt with Raid issues like this before, I have questions, which is why I decided to leave this to the professionals before I attempt anything.
1.How do I get detailed information on hard drive health, to see which one is failing?
2.Can I simply remove the hard drive from the server, and place it in another machine, and fire up HD Senteniel for a more detailed report?
3. Will doing so, and plugging the drive into another machine without it's mirrored counterpart cause the data to become unmirrored, and raise the risk of data loss?
4. Once the failing drive has been identified, how does one rebuild the mirroring RAID setup?
Thanks so much.
