Re: Two Linux nodes are presented the same storage; but the LUNs are discovered/named differently.



You can configure the names used if you want, but you may want to
consider using oracle ASM - then it won't matter what the disks are
named, only what the ASM volume is called. This would only be done on
the first server, and the ASM data should be read by the second server
automatically.
