Installing a Storwize V7000 Gen2 compression accelerator adapter

Use this procedure for installing a Storwize® V7000 Gen2 compression accelerator adapter.

About this task

Extra compression performance can be gained by replacing the compression pass-through adapter in slot 1 on each node canister with the compression accelerator adapter.

If you are installing multiple options in a node canister that is already open on the bench, refer to steps 4 through 10 to add the compression adapter to the node canister.

Otherwise, this procedure installs a compression acceleration adapter in both node canisters.

Procedure

To install a new adapter, complete the following steps:

  1. Locate node canister 1, the node canister on the left of the enclosure when viewed from the rear.
  2. Complete Procedure: Removing a node canister and return here.
  3. Remove the lid of the node canister as described in Procedure: Removing and replacing the lid of a Storwize V7000 Gen2 node canister and return here.
  4. Locate the compression pass-through adapter in slot 1 of the node canister.
  5. Pull the compression pass-through adapter straight up so that its connecting edge disconnects from the connector on the main board.
  6. Remove the compression accelerator adapter from its package.
  7. Place the connecting edge of the compression accelerator adapter on the interface adapter connector.
  8. Ensure that the adapter is perpendicular to the canister main board so that the small tab on the top of the bracket is aligned with the alignment hole in the top edge of the adapter slot.
  9. Maintain alignment while applying pressure to the top edge of the adapter opposite the connecting edge to push the connecting edge into the adapter connector.
  10. Check that the adapter is installed squarely in its slot. If the small tab of the mounting bracket is not positioned correctly, pull the adapter out of the slot slightly and repeat steps 7 onwards to install the adapter correctly.
  11. Replace the canister lid, as described in Procedure: Removing and replacing the lid of a Storwize V7000 Gen2 node canister and return here.
  12. Reinstall the node canister into the enclosure from which it was removed in step 2. If the system is powered, the node canister starts.
  13. Reconnect the cables to the canister, ensuring that the cables go back to the same ports.
  14. When the canister is back online, check the event log for new events and run the fix procedures for any errors present.
    Notes:
    • An event with error code 1199 indicates that a valid hardware change needs to be confirmed. Use the management GUI to run the fix procedure for the event.
    • An event with error code 1470 indicates that the two canisters in the enclosure do not have the same hardware configuration. The event is fixed when the second node canister is also upgraded.
  15. Repeat steps 2 to 14 on node canister 2, the node canister on the right of the enclosure when viewed from the rear.
  16. When the node canister is back online, use the management GUI to check the event log and run the fix procedures for any errors present.
