Hi, can you explain what is the purpose of the -rs switch when creating a cpg ?
Despite the help explaination I don't understand the meaning of that option.
-ssz and -ss are ok for me.
Thanks for your help.

SolutionRow size: The row size determines the level of additional striping across more drives. For example, a RAID 5 LD with a row size of 2 and set size of 4 is effectively striped across 8 drives.
See the HPE 3PAR StoreServ Architecture technical paper (4AA3-3516ENW).
And something I picked up from a 3PAR engineer waaaay back: "Just because there is a knob or switch does not mean it's a Good Idea to fiddle with the default setting." <smile>
Don't bother changing it, like a lot of the options, let the system use its default value.

Re: createcpg -rs
Cool. And a note to any and all that happen to come by these notes: The 3PAR developers have spent a lot of time looking at the data sent in over the years by the Service Processors. The various defaults on the options throughout the system have been tuned to provide optimal use.
To any and all: When in doubt, use the default.
