Cause

The SRM 5.0 upgrade process requires an update of the MySQL engine from myISAM to InnoDB. To that end, this task is no longer required and can be disabled. The task is not disabled out of the box and must be disabled manually. The optimize-tables.task is no longer required for InnoDB tables.

The situation is documented on the Dell Support SRM Product Page, in the M&R 8.0.0.0 Release Notes; HTLM or PDF format.

Resolution

To disable the optimized tables task, go to the SRM UI and follow the steps below:
  1. Log in to the SRM Frontend UI and go to Admin page
  2. Under Home > Physical Overview, click the Primary backend host
  3. Click Tasks > mysql-maintenance-tool/Default/optimize-tables.task
  4. Click Disable to disable the task
  5. Click Home again, and click each additional backend
  6. Click Tasks > Disable the tasks for each backend
