DMP, MPIO, MSDSM, SCSI-3 and ALUA configuration settings
Ok, I'm somewhat confused and the more I read the more confused I think I'm getting.
I'm going to be setting up a 4 node active/active cluster for SQL. All of the nodes will have 2 seperate fiber channel HBAs connecting through 2 seperate switches to our NetApp. The NetApp supports ALUA, so the storage guy wants to use it. It is my understanding that I need to use SCSI-3 to get this to work. Sounds good to me so far. My question is, do I need to use any of Microsoft's MPIO or MSDSM? This is on Win 2008 R2. Or does Veritas take care of all of that?
Also, I read that in a new cluster set up, only connect 1 path first and then install and then connect the 2nd path and let Veritas detect it and configure it. Is that accurate?
Any info or directions you can point me will be greatly appreciated. Thanks!
