Troubleshooting
Problem
The cfgmgr command (or cfgdev on VIOS) displays the following warning and fails to discover a new device:
cfgmgr: 0514-621 WARNING: The following device packages are required for
device support but are not currently installed.
device support but are not currently installed.
This message is followed by one or more file set names such as:
devices.fcp.disk
devices.fcp.changer
devices.fcp.tape
devices.sas.changer
Cause
The cfgmgr command displays this message when it discovers a device for which a driver cannot be identified. However, these file sets listed in the message do not exist. They are generic names based on the type of device. For example,
- devices.fcp.tape means that a fibre-channel attached tape drive was found
- devices.sas.changer means that a SAS-attached media changer (tape robot) was found
File set names printed by cfgmgr for FCP devices
Peripheral Device Type Fileset
0x00 Direct-access device devices.fcp.disk
0x01 Sequential-access device devices.fcp.tape
0x02 Printer device devices.fcp.printer
0x03 Processor device devices.fcp.tm
0x04 Write-once device devices.fcp.worm
0x05 CD-ROM devices.fcp.disk
0x06 Scanner device devices.fcp.scanner
0x07 Optical memory device devices.fcp.disk
0x08 Medium changer device devices.fcp.changer
0x09 Communications device devices.fcp.commo
0x0c Storage Array controller device devices.fcp.array
For SAS attached devices "fcp" is replaced by "sas".
Resolving The Problem
If you see this error while trying to configure new hardware, install the driver file set prerequisites specified by the vendor of the new hardware.
If you are unsure what device is triggering these errors, the devscan tool is useful for scanning storage devices.

Another Probable Cause
Faulty hardware could prevent the device from being identified, which also produces this message. In the following example, the error was due to a faulty FCoE adapter in slot C6:
$ cfgdev
or
# cfgmgr
