Note

If configuring the disk array using a direct-connect terminal, it is also possible to

complete any RAID configuration modifications before attaching the disk array to the

host computer. If terminal emulation is used, the disk array will come up in the factory-

default configuration of RAID-5 LUNs.

Note

MUX support is not available over the Fibre Channel links because of RS-232C

distance limitations. Configuration of disk arrays on Fibre Channel links more than 50

feet from a MUX panel must be done using SAM or STM.
