Hi Vladimir, It seems you want vm to access storage via fibre channel. I did the same thing in a test environment the other day. I connected devices as shown in the diagram below: You should configure all nova nodes follow this: http://docs.openstack.org/grizzly/openstack-compute/admin/content/fibrechannel.html and also configure cinder node like this: http://docs.openstack.org/grizzly/openstack-block-storage/admin/content/hp-3par-driver.html Then cinder will take over the control of disk array, create or delete volume etc. When a volume attached to vm, vm can access it via fibre channel directly. But I don't think HP p2000 is supported, check this: https://wiki.openstack.org/wiki/CinderSupportMatrix On Tuesday, September 24, 2013 10:44:46 AM Vladimir Parf wrote: Hi! Please help sort out the issue with the setting cinder and SAN. I have a SAN storage HP P 2000, and 10 blade servers all connected via Fibre Channel. I can not understand how I configure Cinder. Do I understand correctly that each Compute- node I will have to connect the LUN. For example: compute-node-2 => LUN 10TB (+LVM); compute-node-3 => LUN 10TB (+LVM); compute-node-4 => LUN 10TB (+LVM); compute-node-5 => LUN 10TB (+LVM); Whether to adjust the cinder on each compute-nodes ? How then adjust cinder ins master node? -- ~ Kai -------------- next part -------------- An HTML attachment was scrubbed...
