It's a Dell bay (or "storage array", I think that's the correct name in 
english...)

Actually I jutt made a test : authorize access only to the second host (on the 
Dell bay), it works but only after setting it to maintenance mode and 
reactivate it.
Then authorizing both of the hosts (as initially) make them both working 
now...It doesn't really makes sense...
It is a very strange behavior. Maybe the second host needed to be set in 
maintenance mode then reactivated ?

I didn't choose if it was multipath or not, someone only gave me access to this 
storage, but I understand what you mean. However, I'll certainly add bonding 
later.


Do you have any idea what setting maintenance mode and reactivating does on a 
host ? Does it restart some services ? I don't really understand what just 
happened actually...
All I know is that it is used for backup, reinstall and update.
