No, its different. Passing "-z" tells the adapter to assume all the data on the 
drives is zeroed.
The "--skip-format" just lets iprconfig create a RAID array and not do the 
format. In this case,
the adapter would be told NOT to assume the drive is zeroed and the adapter 
would then do the
parity generation for RAID 5/6/10 as well as T10 DIF initialization.
