This section describes common problems when performing SCSI configuration.

SCSI-Related Configuration Error Messages

This section explains error messages and provides possible solutions to SCSI configuration problems. For more information about troubleshooting SCSI configuration problems, see cfgadm(1M).

Error Message

cfgadm: Component system is busy, try again: failed to offline:
device-path
Resource              Information
------------------  --------------------------
/dev/dsk/c1t0d0s0   mounted filesystem "/file-system"

Cause

You attempted to remove or replace a device with a mounted file system.

Solution

Unmount the file system that is listed in the error message and retry the cfgadm operation.

Error Message

cfgadm: Component system is busy, try again: failed to offline:
device-path
Resource              Information
------------------  --------------------------
/dev/dsk/device-name   swap area

Cause

If you use the cfgadm command to remove a system resource, such as a swap device or a dedicated dump device, a similar error message is displayed if the system resource is still active.

Solution

Unconfigure the swap areas on the device that is specified and retry the cfgadm operation.

Error Message

cfgadm: Component system is busy, try again: failed to offline:
device-path
Resource              Information
------------------  --------------------------
/dev/dsk/device-name   dump device (swap)

Cause

You attempted to remove or replace a dump device that is configured on a swap area.

Solution

Unconfigure the dump device that is configured on the swap area and retry the cfgadm operation.

Error Message

cfgadm: Component system is busy, try again: failed to offline:
device-path
Resource              Information
------------------  --------------------------
/dev/dsk/device-name   dump device (dedicated)

Cause

You attempted to remove or replace a dedicated dump device.

Solution

Unconfigure the dedicate 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. Instead, 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.
