Hello, All:
I've inherited an Oracle VM Server cluster made up of three hosts - each with six interfaces. Those six interfaces are combined into three bonded interfaces:
| Interface | Ports | Configuration |
|---|
| Management | eth0 & eth3 | MODE=1 (active-passive) |
| Storage | eth1 & eth4 | MODE=1, MTU=9000 (active-passive) |
| Guest | eth2 & eth5 | MODE=4 (LACP [VLAN's 100, 200, & 300]) |
Clearly: The Storage Interface is not ideal. (Ideally the two interfaces should be independent of one another so that iSCSI-MPIO can be employed.)
| Interface | Ports | Configuration |
|---|
| Management | eth0 & eth3 | MODE=1 (active-passive) |
| Storage #1 | eth1 | Independent, MTU=9000 (Storage Path #1) |
| Storage #2 | eth4 | Independent, MTU=9000 (Storage Path #2) |
| Guest | eth2 & eth5 | MODE=4 (LACP [VLAN's 100, 200, & 300]) |
But how do I get from Here to There? i.e., It seems to me that I'd need to essentially deconfigure the entire cluster just to reconfigure PIF's eth1 & eth4. And then after reconfiguring the networking I'd need to...
- rediscover the Storage Repositories;
- reassemble the cluster, and;
- reintroduce the guests.
Does that seem about right?
TIA,
