Question : Problem: WTF's up with my iSCSI network config ???
|
|
Experts:
I just purchased an EMC AX4-5i dual-SP SAN appliance; two racks, one for SAS drives and the other with SATA drives. I'm just setting up the appliance and I'm stuck, hoping you all can help me figure something out.
If you look at the attached file you'll notice my vanilla setup: 1 server with 3 NICs connected to a pair of GigE switches configured in a meshed network connecting a pair of SP units, each with two iSCSI ports of their own.
The problem I'm having is that on the server i can only ping one of two switches and only two of four iSCSI ports

So before I go any further and start configuring iSCSI initiators or LUNs, etc...I wanted to clear up this networking mystery
Thanks, juckyt

All you need is Windows 2003 Server Advanced Server
Windows Server 2003 provides an alternative, optional quorum mechanism that is known as majority node set. By using this quorum mechanism, you can build cluster configurations without using a shared, block-level disk device as the quorum disk. In a majority node set server cluster, the quorum data is mirrored on the system disks of all the nodes in the cluster instead of having a single copy on the quorum disk. The Cluster service makes sure that the data is always kept consistent across the different mirrored copies. http://support.microsoft.com/default.aspx?scid=kb;en-us;812504&Product=winsvr2003
