The spaces above ADP, CH, and ID are filled in before shipment to identify the drives.
u
ADP means the RAID controller (adapter) number connected to the RAID disk drives.
u
CH means the RAID SCSI bus channel of the adapter (each adapter has two channels).
u
ID means the identification number of the drive in the slot.
NOTE
When the standard disk drives are configured by Intergraph Computer Systems (as described
below), they assume the ID number of the internal disk section slot.
Three or four RAID disk drives may be installed and configured with the Mylex RAID
controller software at the factory. These RAID disk drives are configured to appear as one
logical drive in Windows NT Disk Administrator. The logical drive has a 2 GB NTFS system
disk partition; the rest of the logical drive is formatted as one NTFS partition, for a total of
two partitions. A RAID disk drive installed at the factory assumes the ID number of the disk
drive bay slot in which it is installed.
The default configuration for factory-installed RAID disk drives is as follows:
u
RAID level 5
u
Write-through write policy
u
Cached I/O policy
u
Two disk drives spin up every six seconds
u
Ultra SCSI enabled
You can use the Mylex RAID configuration utility to manage the RAID disk drives. The
following figure shows the correlation between the disk drives (labeled), their slot location in
the disk drive bay (shaded areas), and how they are identified in Mylex BIOS and the Mylex
RAID configuration utility.

NOTE
SCSI ID 3 is for an optional SAF-TE card. This corresponds to Mylex ID 3. The following
figure displays SCSI IDs and Mylex IDs for the disk drives, but Mylex ID 3 is still shown for
clarity since it appears in the Mylex BIOS and Mylex utility display.
