138With the non-intelligent subsystems we highly recommend you to use only best qualitycomponents (disk shuttles, cables, terminators, etc.).J.4.3.5 Menu Advanced Setup: Configure Controller, Advanced SettingsWithin 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 tochange here.Parameter Alternatives DescriptionShrink BIOS afterPostOffOnAutoThe BIOS is not shrinked after the post phaseThe BIOS is always shrinked after the post phaseThe ICP Controller decides on the BIOS shrinkBIOS RAM alloca-tion methodAutoOlderThe BIOS address space is automatically allocatedThe BIOS address space is allocated according to anolder PCI specificationDMEM mapping Move below 1MBDo not moveThe DPMEM address space is allocated below 1MBThe DPMEM address space is always above 1MBJ.4.3.6 Menu Advanced Setup: Configure Controller, Cluster SettingsThis menu is selectable only with ICPControllers which are equipped withCluster RAIDYNE® and allows theuser to enable the IO channels of theICP Controller for clustering. Specialcare must be taken, that the IO-Processors of a shared channel (SCSIor Fibre Channel) have different IDs, otherwise there will be conflicts.J.4.3.7 Menu Advanced Setup: Configure Controller, Clear Log BufferThe 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 clearall events in this buffer. The Clear Log Buffer function detects possible entries and deletesthem.J.4.4 Menu Advanced Setup: Configure Physical DevicesAfter selection of this menu option ICPCON displays a list of the IO channels (SCSI or FibreChannel) 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 andthe 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
