volume managment

Can anyone tell me why its a bad idea to have rootvg span multiple physical drives

i.e.

hdisk0 00014861356a3c77 rootvg
hdisk1 0001486111354c7c rootvg
hdisk2 00014861fcef6a5d rootvg
hdisk3 none None

thanks

Hi,
in my opinion it's REALLY good idea to have rootvg spanned to multiple volumes. Use LVM to make mirror of logical volumes to at least two physical volumes. By doing that you will avoid problems if one physical volume of rootvg get broken.
