Physical disks from controller do not show up
I have a PowerEdge FX2s blade server with 3 nodes:
- Server node #1
- Server node #2
- Storage node
- Empty
The storage node has 2 controllers, being the first assigned to #1 and the second to #2.
Yesterday 2 of the disks in the second controller (assigned to #2) were showing up as "removed". We shutdown all of the servers and chassis, and the 2 disks were reseated, to check if they were badly connected.
After that, when starting the server, all of the second controller shows up as disconnected in node #2 idrac, the server does not even boot. We no longer see the 2 "removed" disks, but instead we see that all the controller from storage node is not attached to the server.
This is what I see: https://snipboard.io/78QHKF.jpg
I have shutdown servers and chassis, drained power, reset idrac for node #2, and nothing changes.
Node #1 sill boots up properly, but not the other one.
In the chassis idrac, I can see the storage node, and it appears to be ok: https://snipboard.io/C6Fr9h.jpg
How can I try and understand what is happening?

Hello blunt_,
Sorry to read that. Well, this would require a log analysis to really check what happened to those first 2 disks on Controller #2. We should also be checking what were the HDD models and the firmware versions of the hardware components. Also, if you had RAID arrays it is important to know what kind of RAIDs you had. Depending on the RAID resilience you can recover from a 1 or 2 failed disks.
This raid resilience RAC0501 normally is an incorrect connection between the iDRAC interface and the storage controller. Normally, on Chassis Overview / Troubleshooting / Reset componentes you can launch a iDRAC Reset oepration for the storage node. You mentioned you already did this and nothing changed, right?
The storage module is a FD332. I would suggest you both the Troubleshooting HDD setps and then the Troubleshooting for Storage Controller:
1 - Run the appropriate controllers test and the hard drive/SSD tests in system diagnostics (If the tests fail, go to step 3)
2 - Take the hard drive/SSD offline, remove, and reseat the drive assembly in the sled drive slot.
3 - Restart the sled, enter the System Setup and confirm that the drive controller is enabled.
4 - Ensure that any required device drivers are installed and are con gured correctly.
NOTE: Installing a hard drive/SSD into another bay may break the mirror if the mirror state is optimal.
5 - Remove the hard drive/SSD assembly and install it in the other drive bay.
6 - If the problem is resolved, reinstall the drive assembly in the original bay.
7 - If the hard drive/SSD is the boot drive, ensure that the drive is con gured and connected properly.
8 - Partition and logically format the hard drive/SSD.
9 - If possible, restore the les to the drive.
And then, for the Storage Controller Module:
1 - Open the drive drawer.
2 - Check the storage controller module indicators. If the indicator blinks amber, it indicates a fault condition.
3 - Turn off the compute sled to which the storage sled is mapped. The storage sled also turns off.
4 - Remove the storage sled from the enclosure.
5 - Reseat the storage controller module, module cable, and the storage controller battery.
6 - Install the storage sled in the enclosure.
7 - If the storage controller module functions properly, close the drive drawer.
8 - If the storage controller module does not function properly, log in to the CMC web interface and view the properties of the storage controller.
Let us know the result.
Regards.
