HP ESXI - Extending ESXI Array on HP Server

am trying to see how to expand a disk array on a HP ESXI 5.5 server. We are adding a 6th drive to this current RAID6 array.

I found the commands to do it with the HPACUCLI but can't make sense or want to confirm the commands I have are correct.

This is my current array -

Smart Array P420i in Slot 0 (Embedded)  

  Internal Drive Cage at Port 1I, Box 1, OK

  Internal Drive Cage at Port 2I, Box 1, OK

  array A (SAS, Unused Space: 0 MB)

      logicaldrive 1 (410.1 GB, RAID 6, OK)

      physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 146 GB, OK)

      physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 146 GB, OK)

      physicaldrive 1I:1:3 (port 1I:box 1:bay 3, SAS, 146 GB, OK)

      physicaldrive 1I:1:4 (port 1I:box 1:bay 4, SAS, 146 GB, OK)

      physicaldrive 2I:1:5 (port 2I:box 1:bay 5, SAS, 146 GB, OK)
