Got an issue with mkwpar? Have you checked your WPAR filesets?
If you attempt to create a rootvg WPAR with a VSCSI disk, on a system running AIX 6.1 TL6 and you encounter the following error:
# mkwpar –O -D rootvg=yes devname=hdisk5 -n rootvgwpar1
mkwpar: 0960-587 hdisk5 has un-supported subclass type.
Then you should check that the following filesets are installed:
lslpp -L | grep wio
Once these filesets are installed (from the AIX 6.1 install media), then you should be able to create a rootvg WPAR using a VSCSI disk.
