Hi,
Vvectorio means, that the task (in this case three datawriters and a logwriter) runs 
the internal 'vectorio' Routine. They are waiting for I/O completion. Vvectorio uses 
'writev' to write a vector of several pages from different locations in the data cache 
by a single system call to a continous space on a volume. Other states are 'Vsleep' 
where the task is blocked by an explicit sleep call or 'Vblockio' which would mean 
task is waiting for a single block written or read from volume.
