Creating a New Stack

Prior to creating a stack, know which unit will be the management unit and which will be the standby unit.

  1. Power up all units in the stack.
  2. Verify that each unit has the same Dell EMC Networking OS version prior to stacking them together.
    EXEC Privilege mode
    show version
  3. Manually configure unit numbers for each unit, so that the stacking is deterministic upon boot up.
    EXEC Privilege mode
    stack-unit stack—unit—number renumber stack—unit—number.
    Renumbering causes the unit to reboot. The stack-unit default for all new units is stack-unit 1.
  4. Configure the switch priority for each unit to make management unit selection deterministic.
    CONFIGURATION mode
    stack-unit stack—unit—number priority priority
  5. Connect the units using stacking cables.
    NOTE There are two fixed mini-SAS stacking connectors on the PSU side. You can connect mini-SAS cables between units to form stacking.
  6. Reload the stack one unit at a time.
    EXEC Privilege mode
    show system brief
    Start with the management unit, then the standby, then each of the members in order of their assigned stack number (or the position in the stack you want each unit to take).
    Allow each unit to completely boot, and verify that the stack manager detects the unit, then power the next unit.

Example of a Syslog

Figure 1. Creating a new stack
Illustration of creating a new S3100 stack.
In the above example, stack unit 1 is the master management unit, stack unit 2 is the standby unit. The cables are connected to each unit.

Reload each unit in the stack. After the reload is complete, the four units come up as a stack with unit 1 as the management unit, unit 2 as the standby unit, and the remaining units as stack-members. All units in the stack can be accessed from the management unit.

NOTE Before executing show commands, you must wait for 10 to 15 seconds for the download-agent process to start.

To view the stack unit information after the reload, use the show system brief command.
