Enable multipathing in Solaris 10 after Veritas Volume Manager has been installed and configured
Posted on 2010-01-06
I have a server that I am troubleshooting, but did not build. It is connected to a SAN storage array and is utilizing Veritas Volume Manager. Nothing out of the ordinary so far. However, I have noticed that multipathing in Solaris was never enabled, therefore there are two paths to the storage LUNs. Normally, one would enable multipathing early in the stages of building the server, but now that Veritas Volume Manager has already been installed and configured, accessing the storage from two paths, if I enable multipathing those two paths will change to one (as it should). I am wondering if Veritas Volume Manager can handle this, or will it freak out in some way and have to be re-configured because it will change from two paths to one different path? Does anyone have any experience with this? I'd like to get an idea of just how destructive this will be before I do it. Thanks.
