Hi All,

What parameters do i need to modify in the kernel configuration

None that I am aware of. You should be ok without modifying the kernel. You'll just have a larger PE size.

Hi:

There are no kernel changes required to create a 1TB volume group.

Regards!

The items you indicate, PE SIZE, MAX PE PER PV, etc. are NOT kernel parameters. These are parameters that you specify when you create the VG with vgcreate. It is better to create the VG on the command line rather than with SAM.

Do a 'man vgcreate' and you will see information about the items you mention.

We have a 3 x 1TB VG's on one of our servers. They Have a PE SIze of 256MB

Can't remember doing anything else special though (except specifying largefiles etc) and definitely didn't do anything to the kernel.

Good Luck & let us know if you hit any problems
