Bug Description

Hello,

We are trying to create a HA environment with ubuntu release.
the architecture of the plateform is :
3 servers IBM System x3550 -[7978B9G]-
1 server IBM System x3550 M3 -[7944W6B]-
4 HP Proliant BL680c G5

each server has the same network configuration :
eth0 trunked : public and admin
eth1 not trunked : pxe
eth2 trunked : storage network

during the nodes discovery, it seems there is a problem with the 3 servers IBM System x3550 -[7978B9G]-
they are seen with no disk : Disks 0 drives, 0 bytes total

where as when connecting on the node with ssh from the fuel master node we've got the following result for 'fdisk -l' command:
Disk /dev/sda: 73.3 GB, 73283928064 bytes
255 heads, 63 sectors/track, 8909 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0009ea9c

   Device Boot Start End Blocks Id System
/dev/sda1 * 1 3891 31249408 83 Linux
/dev/sda2 7083 8910 14678017 5 Extended
/dev/sda3 3891 7083 25636863 8e Linux LVM
Partition 3 does not end on cylinder boundary.
/dev/sda5 7083 8910 14678016 82 Linux swap / Solaris

Partition table entries are not in disk order

So there is a disk on the server

So when we try to add them to the environnement we've got the following error

Hello,

The problem is that the disks are detected as external (in ServeRaid controllers) and nailgun agent doesn't see them.

Workaround in Fuel 4.1:

ssh to the node:
vi /opt/nailgun/bin/agent
in REMOVABLE_VENDORS add "ServeRA",
exit

You need to do two times, one during bootstrap and another one after the operating system installation.

Hello,

Do I need to reboot the node after the modification in nailgun agent?
