Connecting External SCSI Devices
|
This appendix describes how to connect external SCSI devices to your server.
 To Connect an External SCSI Device
|
1. Locate the SCSI port on your Netra CT server.
You can connect an external SCSI device to the SCSI port on an I/O board, satellite CPU board, or host rear transition module (RTM).
- If you are connecting an external SCSI device to the SCSI port on an I/O board or satellite CPU board, refer to the documentation that came with that board for the location and type of the SCSI port on the board.
- If you are connecting an external SCSI device to the SCSI port on the host CPU RTM, the SCSI port is located on the host CPU RTM installed at the rear of the chassis in I/O slot 1 for the Netra CT 810 server or I/O slot 3 for the Netra CT 410 server.
FIGURE A-1 shows the locations of the connectors on the host RTM. The host RTM is the same for both the Netra CT 810 server and the Netra CT 410 server; only the location in the rear board cage differs.

2. Determine if you need to use the very high density (VHDC) to SCSI 3 adapter cable included in the Netra CT server shipping kit.
- If you are connecting an external SCSI device to the host RTM, connect the VHDC side of the VHDC-to-SCSI 3 adapter cable to the SCSI port on the RTM (see FIGURE A-1).
- If you are connecting an external SCSI device to the SCSI port on an I/O board or satellite CPU board, refer to the documentation that came with the board to determine if the board uses a VHDC SCSI connector.
3. Obtain the SCSI cable from the external SCSI device's shipping kit.
4. Connect one end of the SCSI cable to the SCSI connector on your Netra CT server.
- If you are connecting an external SCSI device to the host RTM, connect the SCSI cable to the SCSI 3 end of the VHDC-to-SCSI 3 adapter cable.
- If you are connecting an external SCSI device to the SCSI port on an I/O board or satellite CPU board, refer to the documentation that came with the board to connect the SCSI cable to the SCSI port on that board.
5. Connect the other end of the SCSI cable to the appropriate SCSI port on the external SCSI device.
Refer to the documentation that you received with the external SCSI device for more information.
6. Set the SCSI ID on the external SCSI device to a SCSI ID that is not being used already by an internal SCSI device in your Netra CT server.
Refer to the documentation that came with your external SCSI device for instructions on setting the SCSI ID on the device.
- If you are connecting the external SCSI device to the RTM in a Netra CT 810 server, add the external SCSI device to the first SCSI chain in the system (c0). Following are the addresses for the SCSI devices on the first SCSI chain in a Netra CT 810 server:
- Upper hard drive (HDD0) - SCSI ID 0 (c0t0d0)
- CD-ROM drive -- SCSI ID 6 (c0t6d0)
- DAT drive -- SCSI ID 5
Note that the lower hard disk drive (HDD1) is on a separate secondary SCSI chain.
- If you are connecting the external SCSI device to the RTM in the Netra CT 410 server, the only internal SCSI device you would have installed in your Netra CT 410 server would be a hard drive, which would be set to SCSI ID 0 (c0t0d0).
- If you are connecting the external SCSI device to the SCSI port on an I/O board or satellite CPU board, verify that the SCSI address for the new SCSI drive is different from the SCSI addresses for any other drives daisy-chained off that SCSI port.
7. Power on the external SCSI device.
Refer to the documentation that you received with the external SCSI device for instructions.
8. Determine if your Netra CT server is powered off or on.
9. Log in to the Netra CT server as superuser.
See Connecting a Terminal Console to a Server.
10. Use the cfgadm command to list all of the attachment-point ID names, including the SCSI controllers.
From the cfgadm list output, find the attachment-point ID name of the SCSI controller where you connected the external SCSI device.
The following example is from a Netra CT 410 server with two SCSI controllers (c0 and c2). The c0 attachment-point ID name is for the SCSI controller on the system's CPU board, and the c0 name is for a SCSI controller on an I/O board installed in the system.
# cfgadm
Ap_Id Type Receptacle Occupant Condition
AL-1 mcd/fhs connected configured ok
CPU bridge/fhs connected configured ok
IO-2 unknown empty unconfigured unknown
IO-4 unknown empty unconfigured unknown
IO-5 unknown disconnected unconfigured ok
c0 scsi-bus connected configured unknown
c0::dsk/c0t0d0 disk connected configured unknown
c2 scsi-bus connected configured unknown
usb0/1 unknown empty unconfigured ok
usb0/2 unknown empty unconfigured ok
usb0/3 unknown empty unconfigured ok
usb0/4 unknown empty unconfigured ok
usb1/1 unknown empty unconfigured ok
usb1/2 unknown empty unconfigured ok
usb1/3 unknown empty unconfigured ok
usb1/4 unknown empty unconfigured ok

11. Use the cfgadm command to configure the external SCSI device to the host system.
Replace controller-ap-id with the SCSI controller's attachment-point ID name.
# cfgadm -c configure controller-ap-id
|
For example, if the attachment-point ID is c2, you would type:
12. Use the devfsadm command to rebuild the /dev and /devices directories.
- If you attached a hard disk, CD-ROM, or DVD-ROM drive to the system, type:
- If you attached a tape drive to the system, type:
After using the devfsadm command, you can use the devices you connected to the adapter's SCSI controller. Refer to the devfsadm(1M) man page for information.
13. Use the cfgadm command to verify that the external SCSI device is connected to the system.
The following example shows a media tray CD-ROM drive, which has an attachment-point ID name of c2::dsk/c2t4d0, configured to the system.
# cfgadm
Ap_Id Type Receptacle Occupant Condition
AL-1 mcd/fhs connected configured ok
CPU bridge/fhs connected configured ok
IO-2 unknown empty unconfigured unknown
IO-4 unknown empty unconfigured unknown
IO-5 unknown disconnected unconfigured ok
c0 scsi-bus connected configured unknown
c0::dsk/c0t0d0 disk connected configured unknown
c2 scsi-bus connected configured unknown
c2::dsk/c2t4d0 CD-ROM connected configured unknown
usb0/1 unknown empty unconfigured ok
usb0/2 unknown empty unconfigured ok
usb0/3 unknown empty unconfigured ok
usb0/4 unknown empty unconfigured ok
usb1/1 unknown empty unconfigured ok
usb1/2 unknown empty unconfigured ok
usb1/3 unknown empty unconfigured ok
usb1/4 unknown empty unconfigured ok
