Dell doesn't "officially" support QLogic HBAs in their cheaper servers like R210 or R310. They support it with R410 upwards. But "official support" is a dubious concept anyway, at least for real men running Debian etc. ;-)
The qlogic HBA worked absolutely fine on the R210 hardware and we have certified it ourselfes. But with the successor, the R210 II, it doesn't: The system just doesn't boot. The BMC log states:
Date and Time: System Boot
POST Err: Post sensor, Timer refresh failed.
The LED diagnostics show 2 and 3, but LED 1 and 4 are not lit. An error led blinks.
Taking the qlogic hba out makes the system boot again. All firmware updates have been tried, also different HBAs from different manufacturing times.
This question is not really about what Dell officially support etc., but I'd rather love to hear from people who know how to diagnose this: What can be done if a PCI Express cards stops a server from booting? Is there any diagnostics port where one can see what's happening besides the BMC log? Did anybody successfully resolve such an issue with e.g. a poweredge server?
Are there any other experiences with the R210 II where it is more picky about extension cards?
Any guy from Dell knowing how to bypass Dells product policy?
