Problems with DL380 Gen9 Smart Array
Solution 1:
What operating system are you using?
Are there any warning lights on the exterior of the server chassis.
Post the errors you received. The actual text, please.
Contact the vendor you purchased from.
Call HP for support.
I suspect cache module failure, but this machine has so many built-in health checks that you should not be in the dark about what's happening.
Can you boot into the Intelligent Provisioning screen (press F10 at boot) and see what the diagnostics say?
