I was installing Database Firewall version 18.104.22.168.0 on a Dell x86 machine (with 5 * 500 GB local HDDs configured in RAID 10) and it got successfully installed. Later on, I came to know that this version doesn’t support host monitor functionality on Windows hosts. The latest version that supports that is 22.214.171.124.0. So that was the time to download and install 126.96.36.199.0. The installation started fine but it failed with an error:
Exception occured anaconda 13.21.263 exception report File "/usr/lib/anaconda/storage/devices.py", OSError: [Errno 2] No such file or directory: '/dev/sr0'
From the script that it is calling i.e. device.py, I guessed it had something to do with the storage. Maybe it was not able to figure out something that was created by the latest version installation. So I removed the RAID configuration and created it again. After this the installation went through without any issues.
