Figure 15. Example Device Concurrent Maintenance display

To perform concurrent maintenance on a device, specify the location of the device by providing the physical location (frame ID and card/device position) of the device. If you do not know the location, use the following information to determine the correct location:

Frame ID

The frame ID is a unique identification number for a frame. It is usually on the control panel of the frame.

Position

This field represents the position of the device within the enclosure as labelled on the frame.

Device resource name

This field shows the logical name assigned to the resource that is the target of device concurrent maintenance. An example of the resource name for a disk unit would be ’DD037’. See the information for the specific resource either in the Hardware Service Manager displays or in the Display Disk Configuration displays. As an example, consider the disk unit device information in Figure 16 on page 60.

Frame serial number

In a limited set of service cases, it may be possible for a server to have more than one frame with the same frame ID. This typically happens in a clustered system environment when a server fails and ownership of its frames transfers to a different controlling server in the cluster. When this happens, the new controlling server now may have two frames with the same frame ID but different frame serial numbers. In this case, you also need to specify the serial number of the CEC that controls the power for the frame on which you want to perform concurrent maintenance.
