It sounds like the firmware flash didn't quite finish properly.  I suggest starting by shutting down the server, unplugging everything, and draining the flea power by holding the power button in for 10 seconds.  Then reseat the iDRAC 6 Express card.  Then plug everything back in, bring it up again and flash the firmware with the racadm command line.    If it won't flash, try "racadm racreset hard" on the command line and try to flash it again.
  Hi, I have a PE T410 equipped with the iDrac6 Express. The problem: After iDrac firmware upgrade there are connection issues. I updated the firmware for the iDrac6 and after that the system BIOS. I use a web browser from a separate management station to manage the iDrac6, but after the firmware upgrade I lose the connection after a while and it doesn't even respond to ping, SSH or telnet. The IP is set to Static. After a warm reboot of the server the iDrac web interface comes alive and responds to ping and web interface, but again after a while, could be anything from two minutes or longer, the connection is gone. Also, sometimes the fans spin up to full speed and what is logged as a firmware watchdog timeout is logged in the iDrac log. This started happening after the firmware upgrade. If it's related to the NIC and web interface not responding I don't know. Here's a log snippet:   eb 26 20:09:58 SysStatus[1375] Previous reboot was due to a firmware watchdog timeout. Feb 26 20:09:08 fullfw[482] Power Supply 2: Status = 0x00, IOUT = 0x0, VOUT= 0x0, TEMP= 0x0, FAN = 0x0, INPUT= 0x0 Feb 26 20:09:08 fullfw[482] Power Supply 1: Status = 0x00, IOUT = 0x0, VOUT= 0x0, TEMP= 0x0, FAN = 0x0, INPUT= 0x0 NOTE: I don't have a redundant power supply.   Here are some specs: Version of iDrac before upgrade: 1.41 (build 13) Version of iDrac after upgrade: 1.54, A00 Version of BMC: 1.54, A06 Version of BIOS: 1.5.3 The NIC selection is set to Shared, there are no VLANS present.  Is there a workaround? Yes, there is. I did a firmware rollback to the original verion 1.41 (build 13) and the problem is gone, both problems with the dropped connection and the reboot (or fans speeding up) action. I really liked the new GUI in iDrac but the connection loss is unacceptable, so for now I'm using the rollback version. Any ideas or thoughts on this? Thanks!
