Channel Settings
Termination
The termination
terms_termination
for this channel of the Intel RAID Controller SRCMR 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 SRCMR must match the existing SCSI
cabling and cable termination. If the Intel RAID Controller SRCMR 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 willbe 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 while the system is
running. Before starting the hot plug procedure, you should prepare the new hard disk 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 to a free
address if that is not done automatically by your 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.
