Chapter 11. How to read a worksheet to cable controller-to-
stack connections for quad-pathed connectivity
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 needed, you can refer to the “SAS cabling rules” section for information about the controller slot
numbering convention, shelf-to-shelf connectivity, and controller-to-shelf connectivity (including the use
of port pairs).
