Change PowerScale IP Address

Introduction

Changing the IP address of a PowerScale cluster that is managed by Eyeglass requires careful handling to avoid service disruption or configuration mismatch. This guide walks you through the necessary steps to update the IP address in Eyeglass safely.

The process includes disabling configuration replication, updating the SmartConnect Service IP, verifying communication, and restoring normal operations. These actions help ensure that Eyeglass continues managing cluster configuration and failover functionality without interruption.

During this procedure, there will be an Eyeglass service interruption. Any configuration items added, updated, or deleted on the source will not be synchronized to the target until the procedure is completed.

1. Prepare Eyeglass for the IP address change by disabling configuration replication.

   Disable from Eyeglass UI

   1. Log into the Eyeglass web page.

   2. Click Jobs to open the Jobs module.

   3. Select all configuration replication jobs. You can use the checkbox at the top of the Job Name column.

   4. Scroll down the Job list and confirm that all Jobs have the state User Disabled.

      note

      If a job is already in Policy Disabled state because the related SyncIQ policy is disabled, it will remain in this state. Eyeglass also does not run configuration replication for jobs that are Policy Disabled, so this state is acceptable to proceed with the Edit IP address procedure.

   5. Click Select a bulk action.

   6. Select Disable.

   Disable from Command Line

   Alternatively, wait for all running Configuration Replication jobs to finish, then run the following command on the Eyeglass Appliance:

   igls admin schedules set --id Replication --enabled false

2. Change the IP Address on the PowerScale Cluster itself.

3. Update Eyeglass for the new IP Address information.

4. Ensure networking between Eyeglass and the new IP address is set up.

   1. Login to the Eyeglass web page.
   2. Click Inventory View.
   3. Right click your desired cluster.
   4. Click Edit.
   5. Enter the new IP Address in the SmartConnect Service IP field and Submit.

   Once you submit, you cannot edit the IP address again without having run the Eyeglass Replication Task at least once.

5. Enable Eyeglass configuration replication.

   1. Enable one Configuration Replication job.
      1. Select: Select a bulk action, then select: Enable/Disable.
      2. The Job State will be updated to the last known state.
   2. Wait for the next Replication Task to begin (within 5 minutes it will start)
      1. Check the status of the Configuration Replication job from the Jobs/Running jobs window.
      2. The Job should run without any error related to unknown source or target.
      3. If no errors, enable the remaining Configuration Replication jobs.
   3. Procedure complete.
