Presenting same LUN to two vpars @ the same physical server

[Primesh Abeysinghe]

I need to create two vpars (vpar1 & vpar2) in single vparhost (host1) and need to present A Single LUN from EVA to vparhost (host1) and share it with both vpars (vpar1 & vpar2) which in the host

Please tell me is it possible sharing storage as describe above

Thanks in advance

Are you talking about vPars 6.x here? I'm assuming so as you are talking about a vPar host (although you should refer to it as the VSP). So assuming you are talking about vPars 6.x, then yes you _could_ present a LUN to the host (VSP), and to the 2 vPars - although you should know that you really aren't supposed to do any processing or carry out any activities on the VSP - it is there purely as a platform for delivering vPars or HPVMs - so why you would want the host to see the LUN, I'm not really sure.

If you are talking about vPars 5.x or earlier - well there is no "vparhost" to present it to, so you could only present to the vPars.

Either way, once you have a LUN presented to the two vPars what are you intending to do with it? You can't put a standard filesystem on it without using a Cluster Filesystem (normal VxFS filesystems don't support concurrent access from multiple hosts), and the only other use I could think of would be ASM or raw disk with Oracle RAC?

Hi Duncan,
Thank you for your reply, my intention is to present same device file to (/dev/disk/diskxx) to both vpars in the same VSP (vparhost)

Thanks,
