Chapter 2 K2 Level 2 RAID Installation Information
Cabling requirements
It is recommended that you use the Fibre Channel cables shipped with your K2 Level
2 Expansion Chassis when making connections. For cable specifications, refer to
Optical cables must meet the appropriate 2-Gbit FC-AL loop standards. You must use
this type of cable to connect a host to the K2 Level 2 controller.
Copper cables must meet the appropriate standards for 2-Gbit FC-AL loops. You
must use this type of cable to connect Expansion chassis.
K2 Level 2 and K2 Level 2 interconnections should maintain consistency. That is, one
FC loop should connect the K2 Level 2’s RAID controller 0 and the K2 Level 2’s
expansion adapter 0. The other FC loop should connect the K2 Level 2’s RAID
controller 1 and the K2 Level 2’s expansion adapter 1. If your K2 Level 2 does not
have RAID controller 1, do not connect any cabling to the K2 Level 2’s expansion
adapter 1.
Do not leave an unused (that is, dangling) cable connected to a Fibre Channel port
because it may cause excess noise on the loop.
Diagnostic cables connect K2 Level 2 and K2 Level 2 units. These cables are required
for the communication of status information between chassis, and support NetCentral
monitoring.
NOTE: Also refer to the K2 Storage System Instruction Manual for cabling
diagrams and step-by-step instructions.
Binding disk modules into groups
After cabling a K2 Level 2 and any K2 Level 2s, you must bind disk modules into
LUNs using the Storage Utility provided by Grass Valley. Refer to the K2 Storage
System Instruction Manual for information on using the Storage Utility to bind drives.
NOTE: Make sure you allow adequate time for binding disk modules into LUNs.
PFR500 and PFR 600 controllers bind each LUN in turn, but take less than a
minute for each LUN. PFC 500 and K2 Level 2 controllers bind multiple LUNs at
the same time, yet take more than an hour to bind a LUN. Large drive capacities
and multiple LUNs can increase the binding time to 10 hours or more.
