Raid driver: failed to init SCSI host 0

In this particular situation, the Linux Kernel module megaraid_sas is failing to load and thus you device is unknown for the system.

Needed infos (at least):

  • Server and PC distro
  • Server and PC Kernel version
  • Output of dmesg | grep megaraid on both of your machines

The error you have on your server Init cmd return status FAILED for SCSI host was introduced with this patch and later modified with this other patch to the driver megaraid_sas in the Kernel v4.14

Possible solutions:

  • This issue may occur regarding your DMA settings on the bios (SME or else); reference; you may try a different settings for the DMA on the bios.

  • A different (newer) kernel version may probably fix the problem as the questioned module/driver is actively developed and had merged a lot of changes lately.
