Now i am facing problem when using dvd media.
whenever i need a dvd i have to add the path for specific vm.
is there any easy way that after putting the media in host the all media is accessible to all vms??
when i try to add path in second VMs it give me error "backing device not exit"
Question is do i need to add same path in all vms if it is then why its giving error.??
i know One Vm can access the data at a time but why again and again path adding and removing required for VMs to access DVD
Solved! Go to Solution.

Re: Virtual DVD problem
HPVM version B.04.00 will handle this.
For earlier versions you need multipathing software.
Hope this helps!

Re: Virtual DVD problem
as far as I know, begining with HPVM 2.0, you can't have an alternate path presented to a VM in order to use pvlink in the VM to configure LVM and/or have an alternate boot path for the VM. Anyway, hpvmcreate/hpvmmodify will complain if you try to add such a path.
As previously said you must rely on multipating at VM Host level.
If you are working with HPVM 4.0, VM Host should be 11.31. In this case instead of using raw devices like /dev/rdsk/cXtYdZ, use new permanent DSF like /dev/rdisk/diskXX for the VM. Multipathing is a native feature of Permanent DSF
