Channel Settings
Termination
The termination (
terms_termination)
for this channel of the Intel RAID Controller SRCU31 can
be set to three different states:
ON: The termination of the lower (low byte) and upper data lines (high byte) is enabled
or disabled depending on the occupied SCSI connectors of this channel
OFF: No lines are terminated
AUTO: All 8/16 data lines are terminated
ID
Changes the SCSI ID (
terms_scsi_id)
of the SIOP (0-7)
WARNING
The SCSI bus termination of the Intel RAID Controller SRCU31 must match the existing SCSI
cabling and cable termination. If the Intel RAID Controller SRCU31 represents one end of the
SCSI bus, its termination must be ON or AUTO. If you change the termination to OFF, it is
likely that the SCSI bus will be unstable and the connected devices may fail. Due to the different
technology, these settings cannot be changed with an FC I/O processor (fibre channel).
Rescan ID(s)
This function allows you to rescan one or all ID’s (
terms_scsi_id)
of the selected SCSI channel. It
displays an overview of all powered SCSI devices which are currently connected with the
SCSI bus.
WARNING
If the hard disk contains valid host drive or array drive information, it will be deleted when
creating new logical drives (
terms_logical_drive)
. All data will be lost.
Hot Plug: Add Disk
With the hot plug (
terms_hot_plug)
function you can add a new hard disk drive while the system
is running. Before starting the hot plug procedure, you should prepare the new hard disk drive and
set the jumpers according to the free SCSI IDs and SCSI bus termination. Ensure the correct
termination (
terms_termination)
of the SCSI bus and set the ID (
terms_scsi_id)
of the hard disk
drive to a free address if that is not done automatically by the storage subsystem. If you do not
know which IDs are in use on the selected SCSI channel, you can find this out in the physical
configuration window. Wrong SCSI bus termination and/or SCSI ID conflicts will cause a failure
of the complete SCSI channel.
