Figure 3-56: First Scsi Reset Warning - ADIC Scalar 100 User Manual

Bus Reset on Power Up is typically enabled. Removing the check mark from this box
disables SCSI bus reset on power-up.
Enable Termination is typically enabled. Removing the check mark from this box
disables the internal termination circuits.
The default Alternate Initiator ID is set automatically by the SNC. When the SNC scans
the SCSI Bus, it determines which IDs are currently being used by target devices and sets
the Alternate ID to the highest ID not in use. You can change the Alternate ID using the
pull-down or typing a new number. To restore the automatic default selection, choose "-1"
from the drop down list. This option is grayed out when the SCSI channel is being set to
Target Mode.
You can press the Rescan SCSI Bus button to rescan the SCSI bus so the SNC can
discover devices that have been added or removed. It also refreshes the data for the
devices on the SCSI channel and updates the display.
Pressing the Reset button reinitializes the SCSI Channel. This will cause the SNC to abort
all pending commands, reset the channel, and perform a rescan.
When you are finished viewing or setting SCSI Channel parameters, you may press
Cancel to abort all changes and return to the main screen or you may press OK to keep
your changes and return to the main screen. If you press OK, two warnings about the SCSI
reset are issued. See Figure 3-56. See also Figure 3-57.

Attention: Use Reset carefully because it causes pending I/O commands to
return failed status back to the host operating system and may have
unexpected results. Make sure all I/O is stopped before issuing this
command.
Attention: when a SCSI channel is changed from Target to Initiator mode,
the values that appear in the Host Id and Alternate Host Id combo boxes do
not default to 0. They default to values that the SNC has most recently used.
