Add Another Local Disk on XenServer as a new Storage Repository
from xenserver console:
that should return an error like this:
Disk /dev/sdb doesn't contain a valid partition table
your local hard drive is "/dev/sdb" or whatever the error the first command shows you
run this command
that will return something like this:
uuid ( RO) : 3614fba9-f5fc-1c57-0b42-58513c51fc1c
name-label ( RW): xenb
name-description ( RO): Default install of XenServer
copy the UUID of your host server to the clipboard.
xe sr-create host-uuid=<your host UUID> content-type=user type=lvmohba device-config:device=/dev/sdb shared=false name-label="Local_Stor_2"
if you get an error you may need to unmount your current local storage in order to add the new one.
to do this, run this command:
get the UUID of your current storage
xe pbd-unplug uuid=<your storage UUID>
then try mounting your Hardware HBA through Xencenter.
This worked for me, hope it does for you too
