IBM Bladecente/ QL HBA's
OES11 patched current
4 cluster nodes, 11 cluster resources...

As documented elsewhere in this forum, issue with expanding volumes:

SAN admin expands volume
in netware world, "refresh devices" shows new space, expand pool, and done

In linux world. new size does not show unless you reboot OR run "multipath -r"

Question, on a node with resources mounted, can you run "multipath -r" without effecting the live volumes OR do you have to migrate all the resources to another node first?

thanks in advance!
