I have a questen about the Network configuration for ISCSI Failover
at the open-e Webinars the sample IP Config are:
Virtual IP Storage: 192.168.10.250 and 192.168.20.250. the Storage Client 192.168.10.251 and 192.168.20.251
all Subnet mask are 255.255.255.0
I know that the virtual IP address must be on a different subnet than the physical IP addresses
But is it possible to use a Subnetmask for the Virtual IP like 255.255.0.0 ? (and the physical IP are not 192.168.xxx.xxx )
For a Multipath config at the Storage Client the Client .10.251 can connect to the Storage over .10.250 and .20.250, also the second NIC at the Storage Client. - four way multipath
At the sample Config from the webinar, the Storage Client .10.251 can only connect to the storage over .10.250 and the .20.251 to the Storage over .20.250 - two way multpath
No, because I get a Error, if I config the sec. VIP:
The entered virtual IP is in the same subnetwork as one of the network interfaces or virtual IPs that already exist in the system.
It is recommend to use IP that has a unique subnetwork class and is not used in any other place in your configuration.
Do you want to continue?
first VIP: 192.168.8.40 / 255.255.248.0
sec. VIP: 192.168.9.40 / 255.255.248.0
Even though you get the warning, you can still have them in the same subnet.
If your iSCSI subnet is independant from all other LAN traffic, this will not be an issue.
