Troubleshooting SCSI Configuration Problems

This section explains error messages and provides possible solutions to SCSI configuration problems. For more information about troubleshooting SCSI configuration problems, see the cfgadm(8) man page.

Busy Component System Errors

To troubleshoot the error cfgadm: Component system is busy, try again: failed to offline: device-path, note the resource information provided with the message.

device-path
Resource              Information
------------------  --------------------------
/dev/dsk/c1t0d0s0   mounted filesystem "/file-system"

/dev/dsk/device-name   swap area

Cause:  You attempted to use the cfgadm command to remove a system resource, such as a swap device or a dedicated dump device, but the system resource was still active.

Solution:  Unconfigure the swap area on the specified device and retry the cfgadm operation.

Solution:  Unconfigure the dedicated dump device and retry the cfgadm operation.

Resolving a Failed SCSI Unconfigure Operation

If you perform a SCSI unconfigure operation and one or more targeted devices are busy, the operation fails. Subsequent DR operations on this controller and target devices will also fail. The following message is displayed:

dr in progress

To resolve the failed operation, reconfigure the controller.

# cfgadm -c configure device-apid

After verifying that the device has been configured, you can proceed with unconfiguring the device again.
