In a Flexible Storage Sharing disk group, the default volume layout is not mirror when creating a volume with the mediatype:ssd attribute (3209064)
As per current VxVM behavior, specifying a subset of disks, such as mediatype:ssd, as a command line argument during volume creation, takes precedence over internal FSS attributes. VxVM does not implicitly apply by default the mirrored volume layout for a FSS volume.
Workaround: Explicitly specify the layout=mirror attribute during volume creation.
# vxassist -g diskgroup make volume size mediatype:ssd layout=mirror
