The server has been restarted; but no luck. We don't think it is a zoning issue; because the same storage has been zoned to another server in the RAC cluster and the other node is able to see the storage. Also; the server was able to see the LUNs until a couple hours ago. The storage administrator does not see WWN's for HBA's login to the SAN fabric. So at this point it is either kernel/HBA/connectivity issue. On Sun, Feb 26, 2012 at 4:50 PM, Marco Shaw <marco.shaw@xxxxxxxxx> wrote: > The server can be restarted/rebooted?
