We run R710s running ESXi 5.1 and they are running in a shared setup. They keep dropping off the network and require a hard reboot.
I have only recently started this role, so I am picking up loads of half finished jobs.
Most have already been upgraded to v1.98 firmware, but one server is currently on 1.80 and just refuses to update to 1.98. I have even tried upgraded to 1.90 firmware as I hought maybe doing it in stages would help but nah. It fails at 30%.
I have tried the web gui multiple rsets and tries and hard reboots. I have compiled my own bootable linux dvd using Dell Repsoitory Manager and it updated everything else but the iDRAC firmware.
I have even used the lifecycle controller repair package and after that I still cant update the iDRAC firmware.
Any body have any ideas on how to proceed?
Also I have been told my numerous people that running in a shared mode is no good for ESXi hosts, but I cant find nay info?
