StorNext 3.1.3 Installation Guide 22
Planning for LUNs Larger
than 1 TB 2
StorNext supports LUNs greater than 1 TB in size if they are allowed by
the operating system. To enable support for 1 TB or larger LUNs, all
StorNext LUNs must be correctly labeled according to the requirements
of the operating system running on the MDC as well as the operating
system running on all connected clients. Disk LUNs can have one of three
labels: VTOC, EFI, or sVTOC (short VTOC).
Required disk LUN label settings based on operating system and LUN
size are presented in
Table 9. Before installing StorNext, decide what
label type will be used, and then install any required operating system
patches or updates (for both MDC and client) as indicated in the notes for
Table 9.

Labels
Caution: StorNext does not support the connection of multiple
devices through fibre channel hubs. Multiple devices must
be connected using fibre channel switches.
Note: After labeling a disk LUN, you must reboot systems running
Solaris before they can access the disk LUN.
