Logical Volume Configurations
On the DR550 SMB, LUNs have been configured based on the total storage capacity ordered. All
disk capacity is allocated for use by TSM. No disk capacity is set aside for other applications or
servers. Below are the LUN configurations set at the factory. If you view the LUN id from AIX, it will
be displayed as a hexadecimal address.
