Hi,

Here's my situation, I've a 8200 with 1 LFF enclosure. The storage now is configure using raid6 CPG.
I'm planning to add another LFF enclosure with 24 disk. Could I create a new CPG for the new LFF disk enclosure?

No
Add the Disks with admithw.
If Tunesys did not start automatic (depend on OS Version), start Tunesys.
Thats all.
No Need to add Disks to CPG or create a new One.

When adding the disk enclosure, Do I need to set the 3par in maintenance mode?

Maintenance Mode suppress E-Mails and HPE is notifyed that you are doing something.
So they did not Call back you for error messages.
No change on the Array itself.
So the answer is: Yes it is better, but nothing serios is happend if not.

+1, there is no requirement to create new CPGs when you add Physical disk enclosures, in fact it is recommended not to. A CPG is simply a logical rule set that will apply to any available disks of the specified type, and the more the merrier.

If you run tunesys it will run a back end process that will re-stripe your current data evenly to all applicable HDDs. That said, if you are running NL drives in R6 I would run tunesys at a period of low activity.
