Preparing an Existing Storage Subsystem for Secure Path
Operation
Perform the following steps before proceeding to installation procedures if you have
an existing storage subsystem that is currently being used in a production
environment and plan to reconfigure for Secure Path operation.
1. Follow normal procedures to back up the data stored on all drives configured on
the storage subsystem.
CAUTION: If you currently have a storage subsystem in a production
environment that is being converted to Secure Path operation, be sure that all
end users have logged off the server and that all I/O to the storage subsystem
has ceased before proceeding.
2. Before installing Secure Path, refer to Table 4-2 for the maximum logical unit
limits that Secure Path supports.
Table 4-2: Secure Path LUN Maximums

CAUTION: Secure Path only recognizes the maximum logical units listed in
Table 4-2 after the software is installed.
NOTE: Offsets may be used, but to properly restrict access, use the selective storage
presentation. Units should begin with D1 and continue consecutively.
