I had a 4 disk RAID 10 configuration (as 2 logical arrays) on one of my servers and noticed that the server was down. When I reboot it, one the disks was missing.
Talked with the datacenter and they have replaced the faulty disk because it was completely dead. I was hoping that the RAID card will accept the disk and rebuild the array automatically but didn't happened. Checked that if the automatic failover feature was on -which it was- and already tried to initialise the disk but still no luck.
I am not sure if I am doing something wrong, so need to get some advices. What's the process and how can I check if the problem with the RAID array or with the disk. Now I can't rebuild the array neither with Adaptec Card Utility nor with arrconf tool.

Not particularly familiar with adaptec, but with most RAID controllers only a disk designated as hot-spare is automatically used to rebuild an array after failure of one of the active drives.
Replacing a failed disk with a new one normally does not automatically trigger an array rebuild. That requires administrator input.
A quick glance in the manual indicates you'll need to do something like:
