This topic describes how to restore your appliance
Layer7 API Gatewayusing the
Gateway Recovery Disk.
This disk restores a hardware Appliance Gateway to its factory state, erasing all information on the hard drive. Do NOT this disk with Software Gateways.
Use this disk when you need to do the following:
- The Gateway appliance needs to be rolled back because of a failed upgrade, or as part of a disaster recovery plan.
- The Gateway appliance becomes corrupted for whatever reason or a faulty hard drive is replaced.
- The Gateway needs to be restored to a baseline state when running in a test environment or when moving from a test environment to a production environment.
The Gateway Recovery Disk is not shipped with the appliance. Support determines whether a reset is required and supplies this disk.
The recovery disk supports the following hardware:
- All hardware configurations listed in Appliance Gateway Compatibility
- nCipher nShield Solo+ HSM
Please note the following points before proceeding:
- The recovery disk is intended for use only onLayer7 API Gateways delivered as an appliance. It does not not work on Software Gateways or Virtual Appliances. DO NOT USE THE RECOVERY DISK ON NON-GATEWAY MACHINES. THE RECOVERY WILL FAIL AND ALL DATA ON THE NON-GATEWAY MACHINE’S HARD DRIVE WILL BE LOST.
- Hardware added to the appliance after delivery by CA Technologies is not supported.
- The recovery process erases theentirehard drive, not just the current partition. Anything stored in other partitions on the hard drive will be lost.
- If possible, back up the Gateway database first. You can restore the database and configuration files when recovery is complete. For more information, see Back Up Gateways.
- Be sure you have a copy of the Gateway license file stored. The license is stored with the database, so if you have backed up the database file first, the license can be applied upon restoration of the database.
Using the Recovery Disk
Layer7 API Gatewayis part of a cluster, contact Support for information on removing the Gateway from the cluster prior to reimaging.
To recover the Gateway using the recovery disk:
- Back up the database, if possible.
- Insert the recovery disk in the disk drive and reboot the appliance.
- Follow the prompts on the screen to begin the recovery process. You can choose to either have the appliance reboot or shut down after the recovery is finished. When the recovery is complete, the appliance is restored to a factory-shipped state.
- Configure the restored Gateway. For more information, see Configure the Appliance Gateway.
- When configuration is complete, restore the Gateway database, if it was backed up in step 1.
- Redo any additional configuration that was made since the Gateway was installed, for example: SNMP, static routing, Gateway redirect rules, keyboard settings, database replication, etc. For assistance, contact Support.
The recovery process cannot be interrupted. If recovery was unsuccessful, the hard drive has already been erased. The only option is to run the recovery disk again.
