If your Linux system on a partition image has become non-bootable or is suffering from critical system errors, you can use Rescue Mode option to recover your system data.
The Fabric Manager provides an option to start the Linux partition image in rescue mode so that you can access the Linux partition from the outside in the event of an emergency. You can use the Rescue Mode to troubleshoot and repair the Linux partition image that has become non-bootable or is suffering from critical errors.
Prerequisites:
The desired partition image is in stopped state.
If the partition image is not in stopped state and not responding to the Soft Shutdown option, then point to Advanced and click Force Halt.
The partition image should be running a Linux operating system supported by ClearPath Forward. For example, RHEL x.x or SLES x.x.
The platform on which the partition image resides should have the supporting image LinEZInstall 1.1.00016 or higher.
