I saw a file server (Dell Server); say it Server1
I saw Dell PowerEdge FX2s (FC830) which i believe functioning as a SAN for Server1
I saw at Dell PowerEdge FX2s a blinking light (Possibly it is a warning lighting to inform there is something wrong?), then most of the employees can not access their files (which are in the file server= Server1)
1) How to check what is "the blinking light" tells at the Dell PowerEdge FX2?
2) How to troubleshoot this problem? (my feeling; just reboot the Server1)
you could connect with iDRAC8 with Lifecycle Controller to remotely manage and view the units status. I have a feeling that the disk array has failed (2 or more drive failures) (hope you have a recent backup)
If you have a maintenance contract with Dell time to get some onsite support.
