News from “The Lab” – New server booting!

And finally my server is up, even though not running yet.

Even after trying to fix the backplane joints that seemed to be broken, it didn’t came up as I wanted it to do.

So I firstly purchased on eBay a replacement backplane, and tried it with no luck.

Then I finally got a replacement PERC 5i card, and I solved my problem with not recognized devices.

I only have to install ESXi and start playing now…

News from “The Lab” – New server faulty?

Today I think I found out what was blocking my new server from properly booting.

This is a close-up of SAS backplane.

It’s quite hard to see, but some pins of the main Cypress component are bent. A close look with a (cheap) PCB inspection microscope made me quite sure that this damage could prevent the PERC card to properly detect the backplane itself and, in turn, the disks.

I asked my colleague to fix the problem by reworking the joints, and tomorrow I’ll test if this patch works.

In the meanwhile I’m watching some spare parts on eBay… Murphy is always watching you…

Stay tuned!

News from “The Lab” – New server troubles…

As I recently discovered, my new server is not working as it should.

After some suggestions from my friends, I tried reseating all of the internal cards, starting from the PERC 5i controller and PCIe riser card. None of them made the server to properly boot.

As a last resource I removed the PERC card (the riser card cannot be removed because it’s used to connect the front panel, with power on switch, to the baseboard). Obviously as expected the F/W initializing , along with PERC BIOS messages, didn’t came up. Connecting only the card, removing connections with the SAS backplane, brought me to the conclusion that the problem could reside into the backplane or the disks. If I remove the disks I’m warned about their absence, but reinserting them doesn’t make any blinking LED to came up.

So I suspect that I have to look after some new disks to check and then pray that the problem is not due to a faulty backplane…

More coming…
