Mellanox IB SB7800 Drive Failure

[barnstormer]

Good morning,

We've had an SSD on our sb7800 infiniband switch fail, have installed a new drive with a cloned image from one of our other identical switches. So far everything looks ok in the management interface, aside the Host ID. Though we do get 1003, 1006 errors when trying to modify some settings, and the time.

Does anyone know how this can be changed? I was unable to locate it in the manual or menus

Also, in the event of an SSD failure, I also contemplated installing the mlnxOS via usb with a blank SSD installed. Curious if anyone has had to do this and can recommend the best course of action.

Thank you in advance!

if you're running 7800 in anything resembling a production environment, I'd rather buy support and RMA the switch.
From the SX6012 experience and a few forum threads here, there are some manufacturing scripts that run on the device that populate the internal database which is located on a different partition. That DB can include information about BIOS, serial numbers and other HW-specific information. TBH I wouldn't waste time if the switch performs its functions and monitoring works.

It is a 6 year old switch we want to keep as a spare for our cluster, was hoping someone had done the process before. I have the ONIE iso and an image of mlnx OS 3.10.4006 that I manage to find online.

I suppose I will try a usb install to a blank drive, hopefully the scripts will run

Aware this is 27 months old, i wonder if you went ahead and succeeded with your plan? or whether others have experience with this?

You can use the recovery installers available in the Mellanox Thread

Buying a decent mSATA SSD shouldn't be too much of an issue hopefully (30-50€...)

No, the 50€ are certainly not an issue - i just hadn't seen the box open yet, and wasnt so sure how easy to get to and swap that SSD is - now after watching this unboxing vid,

, i am confident ... Storfly 300xe SSD.

(I hadnt been able to find any images of the open SB7800 before)
