When two or more disk shelves have the same ID, the system assigns the duplicate disk shelf a soft ID
number equal to or greater than 100. You must change the soft ID (duplicate) number.
a. Run Active IQ Config Advisor to check for duplicate shelf ID alerts or run the
storage shelf show
-fields shelf-id
command to see a list of shelf IDs already in use including any duplicate IDs.
b. If your system has any duplicate shelf IDs, change the duplicate shelf IDs by repeating this procedure.

SAS cabling rules - shelves with IOM12 modules
Disk shelves with IOM12 modules can be cabled in HA pair and single-controller
configurations (for supported platforms) by applying the SAS cabling rules: configuration
rules, controller slot numbering rules, shelf-to-shelf connection rules, controller-to-stack
connection rules, and if applicable, mini-SAS HD SAS optical cable rules.
The SAS cabling rules regarding controller slot numbering rules, shelf-to-shelf connection rules,
and controller-to-stack connection rules described in this guide are the same rules that apply to
all SAS disk shelves, whether they have IOM12, IOM6, or IOM3 modules. However, the
information in this guide is specific to the unique characteristics of disk shelves with IOM12
modules and their use in supported configurations.
