Subscribe to this informationGetting started with Trusted Logging
Learn about using the Virtual I/O Server (VIOS) command line to configure the Trusted Logging capability for increased log security.
By using the PowerSC Trusted Logging capability, you can configure AIX® logical partitions to write to log files that are stored on an attached VIOS. Data is transmitted to the VIOS directly through the hypervisor. Thus, configured network connectivity is not required between the client logical partitions and the VIOS on which the log files are stored.
The VIOS administrator can create and manage the log files by using the VIOS command-line interface. The following table lists the commands that can be used to configure and manage the Trusted Logging capability.
| Command | Description |
|---|---|
| chvlog | Changes the configuration of an existing virtual log. |
| chvlrepo | Changes the configuration of a virtual log repository. |
| lsvlog | Lists the currently defined virtual logs. |
| lsvlrepo | Lists the current configuration of the virtual log repositories. |
| mkvlog | Creates a new virtual log. |
| rmvlog | Removes an existing virtual log. |

The following figure shows the concepts of the Trusted Logging capability.
- Virtual log repositories
Virtual log repositories are directories in the file system accessible by the Virtual I/O Server (VIOS). You can create one or more virtual logs in a virtual log repository. - Virtual logs
A virtual log is a directory in a virtual log repository. - Virtual log devices
A virtual log device is a virtual target device on the Virtual I/O Server (VIOS), attached to a virtual Small Computer Serial Interface (SCSI) host adapter and backed by a virtual log. - Configuring the virtual log repository
You can configure a virtual log repository by using the chvlrepo command. You can display the properties of the virtual log repositories by using the lsvlrepo command. - Creating a virtual log
You can create a virtual log and attach it to a virtual Small Computer Serial Interface (SCSI) host adapter by using the mkvlog command. - Listing virtual logs or virtual log devices
You can list virtual logs or virtual log devices by using the lsvlog command. - Reconfiguring virtual logs or virtual log devices
You can reconfigure virtual logs or virtual log devices by using the chvlog command. - Removing virtual logs or virtual log devices
You can use the rmvlog command to remove virtual logs or virtual log devices from a virtual Small Computer Serial Interface (SCSI) adapter, or to unconfigure a virtual log device. The virtual log can be specified by using the UUID or by the associated virtual log device name, if it exists. - Live Partition Mobility of virtual log devices
When a client logical partition is moved from one host system to another during Live Partition Mobility, new virtual log devices are created on the destination Virtual I/O Server (VIOS). - Virtual log devices with shared storage pools
You can use the Trusted Logging feature to direct log data to a file system shared across Virtual I/O Server (VIOS) logical partitions.
