Preparing for the Installation 1-11
Notes for the Sample SCSI Configuration Chart
1
This information is available in the active Windows Registry after you install all SCSI
adapters and the Windows operating system drivers
(HKEY_LOCAL_MACHINE\HARDWARE\DEVICMAP\SCSI)
.
2
One SCSI ID (typically 7) is not available because the SCSI adapter uses it. To determine
which SCSI ID is not available, check the adapter setup and identify the value of the
Initiator Id
. Note that you can reset or change the
Initiator Id
for an adapter,
but it is not recommended unless you are doing this so that it matches its peer adapter on the
other IOP. Check the adapter vendor’s recommendations for this ID, or use SCSI ID 7 if
possible. Note that SCSI ID and Target ID are equivalent in meaning.
3
The IOP boot disk must be the first hard disk detected in the system configuration: lowest
adapter number (determined by the BIOS), lowest SCSI ID. In a typical single SCSI adapter
configuration, this is SCSI ID 0. Some SCSI adapters support booting from IDs other than
the lowest.
4
For the CE boot disk to map to the
c:
drive when the Endurance server is operational, the
CE boot disk must be the first redirected hard disk detected in the configuration: lowest
adapter number, lowest SCSI ID among redirected disk devices. In a typical (single SCSI
adapter) configuration, this is SCSI ID 1.
Additional Notes:
• IOP boot disks are not redirected to CEs and should occupy the same SCSI address on
both IOPs.
• CD-ROMS can be SCSI devices or IDE devices. All other storage devices (mirrored and
non-mirrored) must be SCSI devices. No IDE devices other than CD-ROMs can be
present in the IOPs. Note, however, that the Windows operating system treats IDE CD-
ROMs like SCSI devices for configuration purposes.
• If you configure a non-mirrored device, the same corresponding SCSI address may not be
in use on the
other IOP (same adapter number).
