You cannot delete the System defined pool and even if the pool is just there it will not harm any thing as it does on have any disk in it.
I want to delete a Celerra pool as it is not being used. This is a "System" pool and not a "User" generated pool. Do I need to shrink the pool first and then delete the pool OR I can go ahead and delete the entire pool itself from GUI and the volumes will also get deleted?  If I shrink a the pool by seleting the volume, will the volumes get deleted and the "nas_disk -l " will show the assossiated disks are unused and then I can delete them will -perm and -unbind option?  The cli manual says, use   -delete with -deep option and it recursively deletes each member of the storage pool. Should I use that option to delete the entire pool instead of deleting from GUI?
