Expanding an existing PowerFlex cluster with SDC authentication enabled

Once a PowerFlex cluster has SDC authentication that is enabled, new SDCs must have the configuration step that is performed after the client is installed. This procedure is not applicable for the PowerFlex management controller 2.0. For Windows PowerFlex compute-only nodes, only firmware upgrades are supported.

Prerequisites

Ensure you have the following information:
  • Primary MDM IP address
  • Credentials for the PowerFlex cluster
  • The IP address of the new cluster members
Ensure you have added the SDC authentication enabled on the PowerFlex cluster.

Steps

  1. Install and add the SDCs as per normal procedures (whether using PowerFlex Manager or manual expansion process).
    NOTE:New SDCs will show as Disconnected at this point, as they cannot authenticate to the system.
  2. SSH to the primary MDM.
  3. Log in to the PowerFlex cluster using the scli tool.
  4. For each of your newly added SDCs, generate and record a new CHAP secret, type: scli --generate_sdc_password --sdc_IP <IP of SDC> --reason "CHAP setup - expansion."
  5. SSH and log in to the SDC host.
  6. If the new SDC is an VMware ESXi host, follow the rest of this procedure.
  7. Type -m scini | grep Ioctl and esxcli system module parameters list -m scini to list the current scini parameters of the host.
  8. Using esxcli, type esxcli system module parameters set -m scini -p to configure the driver with the existing and new parameters.
    For example, esxcli system module parameters set -m scini -p "IoctlIniGuidStr=09bde878-281a-4c6d-ae4f-d6ddad3c1a8f IoctlMdmIPStr=10.234.134.194,192.168.152.199,192.168".
  9. At this stage, the SDC's configuration is ready to be applied. On ESXi nodes a reboot is necessary for this to happen. If the SDC is a hyperconverged node, proceed with step 10. Otherwise, go to step 12.
  10. For PowerFlex hyperconverged nodes, use the presentation manager or scli tool to place the corresponding SDS into maintenance mode.
  11. Once the SDS is in maintenance mode, the SVM may be powered off safely.
  12. Place the ESXi host in maintenance mode. No workloads should be running on the node, as we have not yet configured the SDC.
  13. Reboot the ESXi host.
  14. Once the host has completed rebooting, remove it from maintenance mode and power on the SVM (if present)
  15. Take the SDS out of maintenance mode (if present).
  16. Repeat steps 5 through 15 for all ESXi SDC hosts.
