Planning File Systems and LUNs
The storage-system disk IDs and Storage Group LUNs are as follows.
With 36-Mbyte disks, the LUN storage capacities and drive names are
as follows.
Database Server — 540 Gbytes on four LUNs
Database Server LUNs (DS) - SP A Clustered System LUNs
File Server LUNs (FS) - SP B Mail Server LUNs (MS) - SP A
