How to Add a SCSI Device to a SCSI Bus

SCSI controller c1 provides an example of adding a SCSI device to a SCSI bus.

Only SCSI attachment points are listed. The attachment points displayed on your system will depend on your system configuration.

When adding devices, the ap_id of the SCSI HBA (controller) to which the device is attached is specified, not the ap_id of the device itself.

1. Become superuser.

2. Identify the current SCSI configuration.

   # cfgadm -al ap_id Receptacle Occupant Condition c0 connected configured unknown c0::dsk/c0t0d0 connected configured unknown c0::rmt/0 connected configured unknown c1 connected configured unknown c1::dsk/c1t10d0 connected configured unknown

3. Add a SCSI device to a SCSI bus.

   # cfgadm -x insert_device c1 Adding device to SCSI HBA: /devices/sbus@1f,0/SUNW,fas@1,8800000 This operation will suspend activity on SCSI bus: c1 Continue (yes/no)? y SCSI bus quiesced successfully. It is now safe to proceed with hotplug operation. Enter y if operation is complete or n to abort (yes/no)? y

   1. Type y at the Continue (yes/no)? prompt to proceed.

      I/O activity on the SCSI bus will be suspended while the hot-plug operation is in progress.

   2. Connect the device and then power it on.

   3. Type y at the Enter y if operation is complete or n to abort (yes/no)? prompt after the new device has been inserted.

4. Verify the device has been added.

   # cfgadm -al Ap_Id Receptacle Occupant Condition c0 connected configured unknown c0::dsk/c0t0d0 connected configured unknown c0::rmt/0 connected configured unknown c1 connected configured unknown c1::dsk/c1t10d0 connected configured unknown c1::dsk/c1t4d0 connected configured unknown

   A new disk has been added to controller c1.
