If you press <Enter> on a specific drive, StorCon opens the Configure Disk menu. Here, all
relevant adjustments and modifications concerning the physical drives can be carried out.

NOTE
If you create new host drives with the Express Setup function, the StorCon and the Intel RAID
Controller SRCU32 will automatically adjust all parameters to their respective best values. The
transfer rate per drive depends on circumstances like cables, terminators, etc. For example, if a
certain configuration does not allow 160 MB/sec, the drive is automatically “throttled” down to the
next trouble-free transfer rate. See Figure 44.
Figure 44. Initialize Disk
SCSI Parameter / Initialize
When a SCSI hard drive is initialized the first time by the RAID controller, its SCSI parameters
may or may not be set automatically set to their optimal settings. The following section describes
manual configuration of these settings.
For certain RAID controllers and/or situations, certain
parameters described in this section may not be configurable.
CAUTION
This option can destroy all data on the hard disk.
StorCon copies Intel RAID Controller SRCU32 specific configuration blocks on the hard drive, a
primary block, and a mirrored secondary block. The possible settings are different if you select a
SCSI hard drive or a Fibre Channel hard drive. With a FCAL hard drive there are only a few
settings which are relevant. You should always check that they are all “Enabled” or “On.” If the
hard drive you have selected is an Ultra1 60 device and the Intel RAID Controller SRCU32 has
Ultra160 SCSI channels, <F4> “Advanced Configuration,” allows you to configure the so-called
“Domain Validation” (a cyclical check of the correct data transfer at a given rate). Normally this
parameter is OFF.
The SCSI bus can operate two methods of data transfer: asynchronous and synchronous. Each
SCSI device must be able to perform the asynchronous transfer; the synchronous is optional. The
advantage of the synchronous transfer is a higher data transfer rate, since the signal transfer times
on the possibly long SCSI cable have no influence on the transfer rate. This mode is only effective
if both devices support synchronous transfer and can communicate with each other in this mode.
