LSI MegaRAID Storage Manager: Servers Could Not Be Found

As a system administrator, it's crucial to ensure that your storage setup is functioning correctly. Recently, I faced an issue where my disks weren't showing up in FreeNAS disk manager, and I needed to troubleshoot the problem to get my storage running smoothly again.

After researching the issue, I found that my onboard SAS controllers had a maximum capacity of 2.2TB per disk, which was limiting my ability to take full advantage of ZFS. To overcome this limitation, I decided to install an additional MegaRAID RAID PCI card (元-25121-61A) from SuperMicro.

The main challenge I faced was getting the RAID configuration to be visible in the MegaRAID Storage Manager. Despite the production server being operational 24/7 without any issues, the RAID setup wasn't detectable by the storage manager. This was a concern because it meant that I couldn't monitor or manage my storage setup properly.

I checked the MegaRAID storage managers on other servers to see if they could detect the problematic RAID configuration, and surprisingly, they were able to detect their own and each other's RAIDs. However, they failed to detect the localhost RAID setup. This led me to suspect that the issue might not be related to the RAID configuration itself but rather with the detection process.

To resolve this issue, I needed to determine why the MegaRAID Storage Manager was unable to detect my local RAID setup. After restarting the server and experiencing the same problem, I started to investigate other possible causes. As a result of this investigation, I discovered that the issue might be related to the firmware version used in our MegaRAID configuration.

In order to resolve this problem, I needed to find out if there was any process or procedure that could help make my RAID setup visible to the MegaRAID Storage Manager again. After researching and experimenting with different solutions, I found that the key to resolving this issue lay in ensuring that the firmware used supported JBOD (Just a Bunch Of Disks) configuration.

By installing a firmware version that supports JBOD, I was able to successfully configure my RAID setup and make it visible to the MegaRAID Storage Manager again. This allowed me to monitor and manage my storage setup properly, giving me peace of mind knowing that my data is safe and secure.

In conclusion, resolving this issue required a combination of research, experimentation, and problem-solving skills. By understanding the limitations of our onboard SAS controllers and installing a firmware version that supports JBOD configuration, I was able to successfully configure my RAID setup and make it visible to the MegaRAID Storage Manager again.
