PERC H710 hot-swap?
Hi,
I have a PERC H710 RAID controller in the server. On it RAID5 from 7 disks.
The drives are connected directly to the controller with a Mini SAS SFF-8087 to 4xSATA cable.
I have to replace three disks due to poor condition.
Can I do it like this:
Without shutting down the server, I disconnect the first disk to be replaced and connect a new one.
I am waiting for a RAID5 rebuild with a new disk.
After rebuilding RAID5, disconnect another disk to be replaced and connect a new one.
I am waiting for a RAID5 rebuild. After rebuilding RAID5, disconnect the last disk to be replaced and connect the new one.
I am waiting for a RAID5 rebuild.
Is this how I can do it? Do I have to turn off the server with each replace?
I have web access [Dell EMC OpenManage] to manage this controller.
System on the server: Debian 10
The server is DELL T40.

It is not recommended to directly remove the drive when system is powered on as it can lead to data lost. You can still replace the drive when system is powered on by making the drive offline first then remove and insert new drive. If rebuild is not initiated after few minutes of replacement you can assign the new drive as hotspare of the virtual disk so that rebuild will get initiated.
What Dell EMC OpenManage software you have on the server. If it is OMSA you can make drive offline using OMSA.

My server is DELL T40.
I bought the H710 RAID controller separately.
For it to work properly with my server, I had to seal pins B5 and B6 with insulation tape.
Everything works fast and
