Problems with Intel S5520HC and SC5650DP

[idata]

Hello,

I was setting a soft raid under linux going through this document: http://en.gentoo-wiki.com/wiki/Migrate_to_RAID http://en.gentoo-wiki.com/wiki/Migrate_to_RAID

When I restarted my server, the BIOS hung at the AHCI drives detection step. When either unplugin the 2 drives with linux raid partition or setting SATA to IDE ehanced mode, there is no more hang. Therefore I thought to do a BIOS upgrade.

I updated from EFI to those versions:

System BIOS - 54

BMC Firmware - 00.54

ME Firmware - 1.12

FRUSDR - 28

I still have the same problem with ahci and even worst, all fan stay runing at full speed and the status led is amber and blinking.

Someone could help me please.

Make sure fans are connected to the right connector... For SC5650DP, fans should be connected to Chassis Fan 1, 3 and 5, and of course the CPU fan.

As for RAID in Linux, isn't is easier to use the onboard Intel® Embedded Server RAID Technology II? See http://www.intel.com/support/motherboards/server/sb/CS-029508.htm Demo: Configuring Intel® Embedded Server RAID Technology II and http://www.intel.com/support/motherboards/server/sb/CS-030677.htm Demo: Loading Intel® Embedded Server RAID driver during OS installation.

A chasis fan was indeed pluged in the wrong connector. But I still not understand why I didn't have the fan problem before the BIOS update.

For the RAID, I don't know much about Intel's RAID technology. As I don't use either RHEL nor SUSE but gentoo I don't know if it would be easyer. But it is still more a workaround because I think the AHCI ROM should'nt hang when pluging drives with Linux RAID autodetect partitions.

Thanks for solving my fans issue

I see... Maybe you can check hard drive compatibility http://www.intel.com/support/motherboards/server/s5520hc/sb/CS-030220.htm here.

They are on the compatibility list, both are WD5003ABYX from Western Digital. I forgot to tell, but thought it was obvious. Before creating partitions on them and rebooting, they were detected by the AHCI ROM without any problem, and i was even able to hotplug them.

Seems that there is a problem with the AHCI ROM and the Linux RAID autodetect (0xfd) partitions…
