I have RAID1. 1st of disks failed, I've replaced it and made it RAID comaptible. How can I add it to degraded RAID? I have access to OS (Ubuntu Server 18.04) with perccli installed. Here some helpful information about my case:

I've tried to add disk 32:0 to Virtual Disk v0 in Controller c0:

perccli /c0/v0 start migrate type=RAID1 option=add drives=32:0
Controller = 0
Status = Failure
Description = Conversion to this Raid level is not possible.

What's wrong with it?

In this case, you don't want to migrate the raid Virtual Disk, which is about changing the RAID protection type/level (ie migrating from RAID1 to eg RAID0) and/or capacity.

Instead you want to start a rebuild.

Currently, one drive in your Raid1 array is reported as missing (state=Msng). So you need to affect the new drive to the disk group, and then use the rebuild command:

perccli /c0/s1 insert dg=0 array=0 row=0
perccli /c0/s1 start rebuild
