Hi,

When I try to create a virtual disk in IVM ( integrated Virtual Machine VIO ) I get this message

Problems occurred while processing the data. A summary of all problems for this page are listed below. Additional details for each problem may be located next to the field causing the problem.

  • The partition was successfully created, however virtual disk nimrootvg was not created. The following errors were received:

0------------------------------0
But If manually do it from CLI it works
mkvdev -vdev LV -vadapter vhostx

but how to create vhostX in IVM ?
