M520 in VRTX

Daniel, Thanks for that.

Next question as I have 2 CMC's and it is running on CMC 2 if I power down the enclosure and remove CMC 1 and place CMC 2 in that slot should it recognise that I do not have dual CMC and think I just have a single CMC? Or should I try removing CMC 2 and bringing it up just with CMC 1 to aid troubleshooting?

This started after the enclosure was shutdown to add 2 PRO/1000 PT Dual Port Server Adapters into Slot 2 & 3. They appear to be working correctly and I have disconnected all power and reseated both CMC cards to make sure I didn't disturb one of them whilst installing the Network cards.

Hello

The CMC on the VRTX chassis and the iDRAC on the node both need to be functional for a node to power on. If you are having CMC issues then you should resolve that before troubleshooting the node power issue.

Is the firmware held on the SD card on the CMC?

No, the SD card is used to store information for features like FlexAddress.

Thanks

You should be able to swap the CMCs around in almost any configuration without issue. Redundant CMCs are not required.

There is a lot of shared infrastructure on the VRTX, like power. If this issue started after making a hardware change the first step should be to undo that hardware change.

Thanks
