So - my guess was right... As

So - my guess was right... As per the first line in my post of 7 March:

Something very wrong with your config. If SSO is setup properly you shouldn't see reservation conflicts.

Re: multipath to robotic path is

as many people contacted me about the issue

i have  kernel: st 1:0:7:0: reservation conflict very offen

i found out that i have media server med01, where is robotic controller and med02, which has shared tape drives with med01

solution: when med01 is rebooted, then reservation conflict appear on med02, so med02 has to be rebooted as well after med01 and errors are gone
