SCSI Drive Preparation
To prepare the drives for installation, follow these steps:
1. Remove any terminators attached to the drive or set any drive
termination jumpers to the disabled position.
2. Set the SCSI IDs on the drives.
3. Enable term power on the drives.
Refer to the drive manual for specific information about drive configuration
settings.
Do Not Mix Narrow and Wide SCSI Drives
☛
Note
There is only one internal SCSI channel available to
connect SCSI devices. It is recommended not to mix
narrow and wide SCSI devices on this channel.
In some cases, this may cause signal degradation.
Mixing LVD with Single-ended Drives
If LVD capable drives are installed on a channel with single-ended devices,
all drives on the channel will operate as if they were single-ended devices.
This will also limit the bus length to the single-ended bus length specified in
Table 2-2.
No Fibre Termination
☛
Note
Fibre channels do not require termination; therefore,
no manual termination settings are needed. The Fibre
Channel Cabinet
1
automatically handles Fibre
channel setup requirements.
1. Check the manufacturer’s documentation for the Fibre Channel
Cabinet that you are using.
