We installed OpenStack on one R720(use JuJu and MAAS). Use another R720 as the storage.
The system is Ubuntu 14.04.1 LTS txhbw tyy1
configed it to start in PXE mode.
at first everything went well.
After a power failure, we restart all the servers. Then the R720 for storage just can't be started, just keep restarting automaticly again and again in the PXE mode.
the whole restart process is like this:
first config the memory and iDRAC.
Then the DELL screen.
Starting the PXE mode, during the PXE there is two fails:
(1) Starting load fallback graphics devices.(I don't think this device load fail can cause any problem)
(2) Starting Seed the pseudo random number generator on first boot. as fallow
Then keeping going,
after init the cloud, it shows generation complete and reboot the system. as follow
Now the R720 keeping cycling like this, anyone knows what's the point, any reply will be appreciated.
Thank you guys.
