Cause
Quantum DXI series storage with firmware version prior to 4.0.3 lacks several default devices that exist in typical Linux kernels. The devices below are required by Veeam Backup & Replication, and lack of them generates the error:
- /dev/null
- /dev/zero
- /dev/random
- /dev/urandom
- /dev/tty
Solution
To resolve the issue, perform either of the following operations:
- Upgrade Quantum DXI firmware to version 4.0.3.
- Manually add required devices through Quantum DXi-Series CLI
For example:
sudo /bin/mknod -m 0666 /dev/random c 1 8 sudo /bin/mknod -m 0666 /dev/urandom c 1 9
