than 1 TB on page 21).
• (Linux only) Install the kernel source code (see Installing the Linux
Kernel Source Code on page 23).
Configuring Storage
Devices 2
Before installing StorNext SNFS, make sure that all LUNs are visible to
the MDC. (A LUN, or logical unit number, is a logical device that
corresponds to one or more disks, drives, or storage devices.)
If there are any connection issues, resolve them before installing
StorNext. For assistance in configuring storage devices, refer to the
documentation that came with the storage device, or contact the
manufacturer.
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
Note: LUNs that you plan to use in the same stripe group must be
the same size. Consider this when configuring storage devices.
(For more information about stripe groups, see the StorNext 3.5
User’s Guide.)
Caution: StorNext does not support the connection of multiple
devices through fibre channel hubs. Multiple devices must
be connected using fibre channel switches.
