Introduction 3. Shut down the system. If you are running HP-UX under HP VUE, shut down your system according to the shutdown procedure described in the Owner's Guide that came with your workstation. If you are running HP-UX without HP VUE, shut down your system by typing the following command: # /etc/shutdown -h RETURN You must have superuser privileges to use the /etc/shutdown command. If you do not have superuser privileges, contact your system administrator. If your workstation is part of a cluster, refer to Managing Clusters of HP 9000 Computers for instructions on shutting down. SCSI-2 Connection and Termination Only single-ended SCSI-2 configuration is supported, with a maximum sustained transfer rate of 5.0 MB/second. Only unshielded connectors can be used. The DDS-2 drive does not support termination on the device itself. Normally, drives such as this are not required to be at the end of a bus, but if this is unavoidable, HP recommends using a feed-through SCSI terminator that plugs directly into the rear of the drive. Use active termination, as the drive is capable of a transfer rate greater than 5 MB/second. If you do not already have a SCSI terminator, you must order either terminator K2291 (bale-lock style) or terminator C2094A (thumbscrew style). NOTICE: Use care when inserting and removing feed-through terminators to avoid damaging the end walls of the terminator and the drive. 1-13

3.
Shut down the system.
If you are running HP-UX under HP VUE, shut down your system according to the
shutdown procedure described in the Owner’s Guide that came with your worksta-
tion.
If you are running HP-UX without HP VUE, shut down your system by typing the
following command:
#
/etc/shutdown -h
RETURN
You must have superuser privileges to use the
/etc/shutdown
command. If you do
not have superuser privileges, contact your system administrator.
If your workstation is part of a cluster, refer to
Managing Clusters of HP 9000 Com-
puters
for instructions on shutting down.
SCSI-2 Connection and Termination
Only single-ended SCSI-2 configuration is supported, with a maximum sustained transfer
rate of 5.0 MB/second. Only unshielded connectors can be used.
The DDS-2 drive does not support termination on the device itself. Normally, drives such
as this are not required to be at the end of a bus, but if this is unavoidable, HP
recommends using a feed-through SCSI terminator that plugs directly into the rear of the
drive. Use active termination, as the drive is capable of a transfer rate greater than 5
MB/second.
If you do not already have a SCSI terminator, you must order either terminator K2291
(bale-lock style) or terminator C2094A (thumbscrew style).
NOTICE:
Use care when inserting and removing feed-through terminators to
avoid damaging the end walls of the terminator and the drive.
