    Does vMotion or SVmotion work with NPIV enabled.

    nicholas1982 Hot Shot

      If anyone can accurately advise on this it would be much appreciated.

       

      We are building a new FC fabric using the Cisco MDS 9000. After reading many docs, it seems it would be best practice to enable NPIV.

       

      However I just read some conflicting info on the following URL:

       

      http://pubs.vmware.com/vi35/fibre_san_config/wwhelp/wwhimpl/common/html/wwhelp.htm?context=fibre_san_config&file=esx_san_cfg_manage.8.19.html

       

      “Note If you want to use VMotion for a virtual machine with enabled NPIV, make sure that the RDM file is located on the same datastore where the virtual machine configuration file resides. You cannot perform Storage VMotion, or VMotion between datastores, when NPIV is enabled. “

       

      One part say if you want to use vMotion for a VM with NPIV do the following.. The last bit says you can’t vmotion if NPIV is enabled.

       

      We are not currently using RDM’s but we thought if there is a requirement in the future NPIV would be enabled.

       

      My main question is what do they mean by.. You cannot perform Storage VMotion, or VMotion between datastores, when NPIV is enabled. ?

       

      And can anyone tell me if there is any reason why we should not enable NPIV ?
