- Red Hat Virtualization
I have created an iSCSI target that has access from 2 networks: 18.104.22.168 and 22.214.171.124. On the RHEV host, I have setup multipath to access this disk in a round-robin fashion, using friendly name "blue":
# multipath -l
blue (188424d93-8676-425d-9c63) dm-0 Perrier,VIRTUAL-DISK
size=198G features='0' hwhandler='0' wp=rw
|-+- policy='round-robin 0' prio=0 status=active
| `- 10:0:0:1 sdb 8:16 active undef running
`-+- policy='round-robin 0' prio=0 status=enabled
`- 9:0:0:1 sdc 8:32 active undef running
This disk was handed to the datacenter as a data/iSCSI domain. I checked both paths in the New Domain dialog box, see attachment.
I believe that both paths are being used when I create VMs on this disk.
Is this the correct way to implement multipath in RHEV?
I preferred to not use NIC bonding, because of past difficulties getting the NetAdmin to adjust Cisco properties on the core switch.
