HP SAN, LUN, and iSCSI help
Posted on 2010-11-12
Our organization just purchased and 'installed' an HP MSA2312 SAN device. Currently it has two physical hard drives installed:
It has two storage controllers, each with an ethernet port (for management) and 2 iSCSI gigabit ports.
I created a vdisk using the 2TB drive and 3 equal sized volumes of about 665GB in that vdisk.
The 4 iSCSI ports connect into an HP 2524 Gigabit switch. The servers that will use the SAN connect into this same switch as well.
From what I understand, you cannot 'mount' the same iSCSI drive (volume?) to multiple machines without causing corruption unless you have a clustering file system.
What I would like to do is connect each of the 3 volumes to a different server, but make it possible for the transfer of data to take place over any of the 4 iSCSI ports on the controllers. Is this possible? Does an iSCSI connection have to be mapped to a specific port and specific server? As long as I have different volumes, can I mount them to any number of servers using any combination of the 4 ports?
Please let me know if I need to clarify anything
