d. Cable controller 2 port 2b to stack 1, last shelf IOM A port 3.
2. Cable port pair 1c/2d on each controller to stack 2:
a. Cable controller 1 port 1c to stack 2, first shelf IOM A port 1.
b. Cable controller 2 port 1c to stack 2, first shelf IOM B port 1.
c. Cable controller 1 port 2d to stack 2, last shelf IOM B port 3.
d. Cable controller 2 port 2d to stack 2, last shelf IOM A port 3.
How to read a worksheet to cable controller-to-stack connections for quad-pathed connectivity -
shelves with IOM12 modules
You can use this example to guide you through how to read and apply a completed
worksheet to cable stacks of disk shelves with IOM12 modules for quad-pathed
connectivity.
About this task
• This procedure references the following worksheet and cabling example to demonstrate how to read a
worksheet to cable controller-to-stack connections.
The configuration used in this example is a quad-path HA configuration with two quad-port SAS HBAs on
each controller and two stacks of disk shelves with IOM12 modules.
• If you have a single-controller configuration, skip substeps b and d for cabling to a second controller.
• If needed, you can refer to SAS cabling rules for information about the controller slot numbering
convention, shelf-to-shelf connectivity, and controller-to-shelf connectivity (including the use of port pairs).
