Hello colleague We use RHEL4 update 3, RHCS and SAN device. There are different possibilities for persistent naming/binding. What are the advantages and disadvantages of the different solutions? Which is recommended? I would be very gladly for short configuration excerpts. 1) RDAC driver /var/mpp/devicemapping 2) udev a new rule in /etc/udev/rules.d 2) devlabel assigned name (mapped to UUID), this label in cluster.conf further possibilities?
