12.2 Backing up data in a JP1/AO system (cluster configuration)

Back up the configuration information and database information of JP1/AO and JP1/Base before you perform tasks such as migrating JP1/AO to a new host or performing database maintenance.

Important note

If you leave too much time after backing up the JP1/Base data, the status of the JP1/AO database will have changed. This can lead to inconsistencies between the current JP1/AO data and the JP1/Base backup data. For this reason, back up JP1/AO and JP1/Base in quick succession.
When you back up and restore data in a JP1/AO system, some aspects of the data do not survive the backup process. For example, some of the detailed task information (step lists and progress information) is lost, and some task statuses are changed.
Make sure that sufficient free space is available on the disk on which the folder for backup files is located. As a general rule, the amount of free space should exceed the size of the backup files by 20 MB.

Who can perform this task:

Domain user with Administrator permissions for the OS and administration permission for the cluster

To back up a JP1/AO system (cluster configuration):

Make sure that there are no tasks in In Progress, Waiting for Response, Abnormal Detection, or Terminated status. If there are such tasks in the system, either stop the tasks, or wait until they enter Completed or Failed status.
Take the following services and scripts registered in the cluster software offline:
- stopcluster command
- HAutomation Engine logical-host-name
- HAutomation Engine Web Service
- HBase Storage Mgmt Web Service
- HBase Storage Mgmt Common Service
- Services of Hitachi Command Suite products
Shut down the JP1/AO system by executing the hcmdssrv command with the /stop option specified.
In the cluster software, take the registered HiRDB/ClusterService _HD0 service offline.
Disable failover of the services and scripts registered in the cluster software.

In the cluster software, set J1/AO so that it does not restart if resources enter Failed status.
- JP1/Base_logical-host-name
- JP1/Base Event logical-host-name
- HiRDB/ClusterService _HD0
- HBase Storage Mgmt Common Service
- HBase Storage Mgmt Web Service
- HAutomation Engine Web Service
- HAutomation Engine logical-host-name
- stopcluster command
- Services of Hitachi Command Suite products
Back up the following JP1/Base configuration information and database information shown below. For details about the backup procedure, see Backup and recovery in the Job Management Partner 1/Base User's Guide.
- Definition file
- Common definition information
Execute the backupsystem command to back up the database and configuration information for JP1/AO.
Tip
The files below are not backed up by the backupsystem command. Back them up manually if necessary:
- SSL server certificate file for HTTPS connection
- Private key file for HTTPS connection
- Private key file for public key authentication
Shut down the JP1/AO system by executing the hcmdssrv command with the /stop option specified.
Enable failover of the services and scripts registered in the cluster software and listed below.

In the cluster software, you can configure JP1/AO to restart resources when they enter Failed status on the current node, and to fail over the resources if they could not be restarted.
- JP1/Base_logical-host-name
- JP1/Base Event logical-host-name
- HiRDB/ClusterService _HD0
- HBase Storage Mgmt Common Service
- HBase Storage Mgmt Web Service
- HAutomation Engine Web Service
- HAutomation Engine logical-host-name
- stopcluster command
- Services of Hitachi Command Suite products
Take the following services and scripts registered in the cluster software online:
- HiRDB/ClusterService _HD0
- HBase Storage Mgmt Common Service
- HBase Storage Mgmt Web Service
- HAutomation Engine Web Service
- HAutomation Engine logical-host-name
- stopcluster command
- Services of Hitachi Command Suite products

Data is backed up to the specified backup folder.
