Hi,
We are using PowerPath in our current Oracle VM production environment and have created a test setup of OLVM.
Now am trying to switch from MultiPath to PowerPath on the KVM server, but OLVM gives some errors/warning if multipath isnot running.
Any idea's about how to switch from MultiPath to PowerPath ? should I have powerpath installed before add the KVM Host to OLVM ?
Or do I need to do some extra configuration ?
What I did to install PowerPath ?
- Stop multipath, disabled the service, set a blacklist in mutlipath.conf, installed the powerpath rpm, replaced the initramfs img
After reboot only powerpath was actve, but I had to do a reinstall from OVLM to get the KVM host active in OLVM.
That restored the multipath.conf and started multipathd. Now I can list the luns via multipath -ll and powermt display dev=all.
Regards,
Pascal
