Enabling/Disabling Automatic Self-Healing

Automatic self-healing and the self-healing delay timer are server group settings. The setting is enabled by default.

The self-healing delay timer can be set to a value to allow for possible outages of a temporary nature. In the console, the delay value may be set from a minimum of one minute to a maximum of 1,000 minutes. The default is eight minutes.

Using the DataCore Cmdlet Set-DcsServerGroupProperties, the minimum self-healing delay value that can be set is 5 seconds. When set to 5 seconds, the value in the console is displayed in minutes and therefore will be reflected as zero.

  • A Witness must be configured for use with automatic self-healing in the event that virtual disks lose all mirror access between storage sources and management communication paths. See Witness.
  • If the setting is disabled after the timer has started, but before the restoration process has begun, the self-healing will be canceled and the timer is stopped. If the setting is disabled after the restoration process has begun, the process will not be stopped.

To enable and set the delay:

  1. In the Task Details page>Settings tab, under Advanced Settings, select the Automatic Self-healing Enabled check box. This enables the delay timer settings.
  2. In Self-healing delay, keep the default value or enter the number of minutes required.
  3. Click Apply.

To disable:

  1. In the Task Details page>Settings tab, under Advanced Settings, clear the Automatic Self-healing check box. (This disables the delay timer settings.)
  2. Click Apply.
