Baremetal hardware has been configured to have a dedicated LUN from HP EVA 8400 using multipath. When applying Nova proposal, just below the volume settings, I see 8 disks sdb to sdi with identical sector size. There are 8 multiple paths to this LUN. Before applying Nova proposal, following steps were done to support multiple path and setup a physical raw device to be configured as Nova-volume:
After OS installation, install multipath-tools
apt-get install multipath-tools
Run the following to get WWID for the dedicated LUN
/lib/udev/scsi_id -g -u -d /dev/sdb
Copy the template multipath.conf file to /etc folder:
cp -ip /usr/share/doc/multipath-tools/examples/multipath.conf.synthetic /etc/multipath.conf
Edit the /etc/multipath.conf file to replace the following:
defaults {
user_friendly_names yes
multipaths {
multipath (
wwid <derived from step 4.>
alias
Reboot the machine
Validate if shows up in the folder /dev/mapper
Please point if I missed any specific step.
