With the non-intelligent subsystems we highly recommend you to use only best quality
components (disk shuttles, cables, terminators, etc.).
J.4.3.5 Menu Advanced Setup: Configure Controller, Advanced Settings
Within Advanced Settings there are three settings which control the configuration and ad-
dress behavior of the ICP Controller’s BIOS and DPMEM. Normally, there is nothing to
change here.

J.4.3.6 Menu Advanced Setup: Configure Controller, Cluster Settings
This menu is selectable only with ICP
Controllers which are equipped with
Cluster RAIDYNE® and allows the
user to enable the IO channels of the
ICP Controller for clustering. Special
care must be taken, that the IO-
Processors of a shared channel (SCSI
or Fibre Channel) have different IDs, otherwise there will be conflicts.
J.4.3.7 Menu Advanced Setup: Configure Controller, Clear Log Buffer
The ICP Controller records certain events in a logging buffer which is part of the Flash-RAM.
If it is planned to use the ICP Controller in a completely new system, it is sensible to clear
all events in this buffer. The Clear Log Buffer function detects possible entries and deletes
them.
J.4.4 Menu Advanced Setup: Configure Physical Devices
After selection of this menu option ICPCON displays a list of the IO channels (SCSI or Fibre
Channel) and the available devices. This list can be scrolled with the cursor up/down keys.
The first column displays the IO channel (“SCSI“ stands for SCSI and “FCAL“ for Fibre-
Channel). The next column shows the ID followed by the LUN (Logical Unit Number; nor-
mally always 0). The next column is either filled with a small “i” (for initialized), or empty.
Initialization means the creation of ICP-specific configuration data on the hard disks and
the adjustment of hard disk specific operating parameters (protocol, transfer rate, etc..).
The next entry lists the vendor and type of device, followed by the drive’s attributes (RW for
