Compute Module: MFS5520VIR
Boot Drive: Storage pool consisting of 2 Intel 320 Series 80GB SSDs (part # SSDSA2CW08) . Two virtual drives configured as RAID 1 arrays
OS: VMWare ESX 5.1
There are two compute modules that each have their boot drives configured on this storage pool. There are other compute modules in this chassis that use non-SSDs for their storage pools & virtual drives.
The two compute modules using the SSD virtual drives consistently have issues booting. The watchdog timer always performs a hard reset at least once on these compute modules during reboots, often two and three times. The two events that appear in the event log are:
3522 - BIOS FRB2 Watchdog timer expired - The server was hard reset
3520 - Watchdog timer expired - The server was hard reset
The compute modules that boot to drives in the non-SSD storage pools never have this issue. Has anyone else experienced this?
Did you monitor the boot process and see in which stage was the server rest? Did you assign a non-SSD VD to this compute module and see if it still has this issue?
Also please check the following BOIS settings:
Server Management => FRB-2 Enable [Enabled] It will reset the server if it doesn't complete the POST in ~6 mins.
Server Management => OS Boot Watchdog Timer [Disabled] This should be disabled unless Intel System Management Software is installed (not available on VMware ESXi)
Also, do you have AXXTM3SATA installed? See http://www.intel.com/support/motherboards/server/mfsys25/sb/CS-030937.htm Intel� Modular Server System MFSYS25 — AXXTM3SATA board and bracket assembly install guide
The drives do have the AXXTM3SATA adapters installed.
I was monitoring the boot process via remote KVM, but during the first two attempts nothing actually displayed in the KVM remote screen.
I will double check the BIOS settings you mentioned and also attempt booting to a non-SSD device.
