unsupported drive, critical error.

I am operating a PowerStore 1000T at an IT company. Three months ago, I purchased five drives to expand capacity. A Dell 3rd party engineer came to install them, and everything worked normally that time.

Recently, due to electrical issue at the company, we powered off the 1000T and turned it back on. That’s when a terrible issue occurred. The five expanded drives reported the following critical errors:

• Drive in bus 0 enclosure 0 slot 10 has failed for this reason: unsupported drive.

• Drive in bus 0 enclosure 0 slot 11 has failed for this reason: unsupported drive.

• Drive in bus 0 enclosure 0 slot 12 has failed for this reason: unsupported drive.

• Drive in bus 0 enclosure 0 slot 13 has failed for this reason: unsupported drive.

• Drive in bus 0 enclosure 0 slot 14 has failed for this reason: unsupported drive.

The services provided by these drives have stopped, and we can no longer access the data.

I contacted Dell regarding a possible drive installation issue, but Dell said there was no problem with the drives themselves and that they could not resolve the issue.

I suspect the problem occurred because the system is treating the drives as unrecognized/unsupported. I’m wondering if installing the OS and drive drivers could resolve this. The PowerStore OS version is 3.6.0.0, which was released on September 14, 2023.

My biggest concern is that the data has been corrupted and will no longer be accessible.

Is my response plan appropriate, or is this something that requires a Dell engineer to handle?
