  • When the upload is completed successfully, the user can proceed to Step 2. The user may also decide to use the 'Reset' button to delete the uploaded package. Step 2 in upgrade involves checking the following conditions.
    1. Volume Access Group definition has any of the following conditions
      1. Volumes are assigned to 'Default' Volume Access Group (VAG)
      2. If only IP address of a VAG is configured, CHAP is set to 'Any User' and IQN is not defined
      3. If same IQN is found in another VAG
    2. A Cloud Snapshot of the volumes has been taken (completed) in the past 24hrs.
    3. A version compatibility in the various modules
    4. Cloud accessibility
    5. Critical hardware alert(s) in the system

If any of these criteria are not met, this check will fail. If there is a version mismatch, please contact StorSimple Support to resolve the issue.

  • Click on 'Start Validation' to initiate the validation process as shown below.

  • If the validation is successful, the user can proceed to Step 3 and start the actual upgrade. If the validation check fails, then a 'View Results' button is presented to the user. Click on 'View Results' to understand why the validation check failed.  A sample of such an error message is shown below.

  • In the above case, the user needs to assign a non-default Volume Access Group to the volumes indicated in the above dialog.
  • Once the above issue is resolved, initiate the validation check again. If the validation is successful, the user can proceed to next step that involves the actual upgrade.MFirenze9S.png

  • The controller upgrades are followed by 8 stages of data migration as described below:
    • Stage 1 prepares space for the new data format
    • Stage 2 involves converting Cloud and Volume configurations to new format
    • Stage 3 converts data to new format
    • Stage 4 converts SCSI settings to new format
    • Stage 5 involves converting system settings to new format
    • Stage 6 comprises of cleaning up
    • Stage 7 increases space for current data format
    • Stage 8 optimizes data layouts

Stage 1, 3 and 8 are long. The duration of these stages is determined by the total data residing on the appliance and the appliance model. Stages 2, 4,5,6 and 7 are short.

  • During stage 8 of upgrade, the new software version will be displayed on the top right corner of the home page.
  • While stage 8 is in progress, you can proceed to upgrade the DPC software. If this software is not upgraded following an appliance software upgrade, there will be a version mismatch. As a result, all scheduled backups will fail until the DPC software is upgraded and the client certification process is complete. See 'Install DPC software' for next steps.
