Hi Yuan,
thank you for your advice.
We configured again all xcat tables (hosts, mac, nodehm, nodelist,
noderes and nodetype) using "arc06" instead of "arc06.lcg.cscs.ch" as
node name and we realized that the problem wasn't xcat but the the
resolv.conf. In effect we missed lcg.cscs.ch in the resolv search list
on our installation server and this explained why xcat failed.
Now everything is working as expected.
Best regards,Carmelo
