Prepare to add the drive shelf

Before you hot add a drive shelf, you must check for critical events and check the status of the IOMs.

Before you begin
  • The power source for your storage system must be able to accommodate the power requirements of the new drive shelf. For the power specification for your drive shelf, see the Specifications of drive shelves.
  • The cabling pattern for the existing storage system must match one of the applicable schemes shown in this guide.
  1. In ThinkSystem System Manager, select Support > Support Center > Diagnostics.
  2. Select Collect Support Data.
    The Collect Support Data dialog box appears.
  3. Click Collect.
    The file is saved in the Downloads folder for your browser with the name support-data.7z. The data is not automatically sent to technical support.
  4. Select Support > Event Log.

    The Event Log page displays the event data.

  5. Select the heading of the Priority column to sort critical events to the top of the list.
  6. Review the system critical events for events that have occurred in the last two to three weeks, and verify that any recent critical events have been resolved or otherwise addressed.
    Note: If unresolved critical events have occurred within the previous two to three weeks, stop the procedure and contact technical support. Continue the procedure only when the issue is resolved.
  7. Select Hardware.
  8. Select the IOMs (ESMs) icon.
    The Shelf Component Settings dialog box appears with the IOMs (ESMs) tab selected.
  9. Make sure that the status shown for each IOM/ESM is Optimal.
  10. Click Show more settings.
  11. Confirm that the following conditions exist:
    • The number of ESMs/IOMs detected matches the number of ESMs/IOMs installed in the system and that for each drive shelf.
    • Both of the ESMs/IOMs show that communication is OK.
    • The data rate is 12Gb/s for DE120S, DE240S, and DE600S drive shelves.

Go to Install the drive shelf and apply power.
