Planning the Storage Layout
SAP Instance Storage Considerations
Chapter 2 61
The table can be used to document used device minor numbers. The
device minor numbers of logical volumes need to be identical for each
distributed volume group across all cluster nodes.
If you have more than one system, place /usr/sap/put on separate
volume groups created on shared drives. The directory should not be
added to any package. This ensures that they are independent from any
SAP WAS system and you can mount them on any host by hand if
needed.
