SAS Disk not recognized

@DELL-Joey C​

Led indicator blink about 2 times on some disks on server start but then just dark.

Im new owner so i don't know.

All cables look good.

I don't see that prompt.

I use this: XP569

Hello,

Are you saying you are new owner and don't know if the server worked?

Try power off and reseat the backplane. Remove it and the cables then reinstall it with cables. Test results.

Since you are unsure if it worked you may try a minimum to post configuration. If it POST you can put other components back a little at a time until you find the faulting component.

Minimum to post (this is minimum components to POST, it won't boot, this is to test POST. If successful POST, put things back a little at a time until find faulting component)

The minimum components to allow the PowerEdge R520 to complete POST are:

*System Board

*CPU1 with heat sink (minimum for troubleshooting)

*Single DIMM configuration with DIMM in socket A1

*Control Panel with cable (to power system on)

*Expansion Riser

*PSU (and for redundant PSU also the PDB/PIB)

Remove anything not on that list: DVD, Hard drives, PERC controller, backplane, network card, NIC cable, any pcie cards, keyboard, mouse, USB devices, …. anything not on the list remove.

If it does not post then the issue is with one of those components.

If you get successful POST, put things back a little at a time until you find the faulting component.

Problem is BIOS don't recognise disks.

Hi, it may a hardware problem. Please try at firs power drain then if you have still same issue try to How to use the Repurpose or retire system feature of the PowerEdge Lifecycle Controller https://dell.to/3UNOXvr

1. Power the server down.  
2. Disconnect server from all power cables, Network cables. 
3. Hold down the power button continuously for at least 10 seconds.  
4. Insert power cabless and network cables back to the system.  
5. Wait about 2 minutes before powering on the server for iDRAC to be refreshed.
6. Power the system on.
