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.
