Dell PERC 4/im - Manual (Page 10)

Restore
Defaults Executable Press Enter to obtain default settings.
Verify Executable Allows verification of all sectors on a device and reassigns defective
Logical Block Addresses, if enabled. To verify all sectors, select the
device from the menu and use the arrow keys to move the cursor to
the Verify column. Press Enter.
Format Executable Allows low-level formatting on a disk drive, if enabled. Low-level
formatting will completely and irreversibly erase all data on the drive.
To low level format a device, select the device from the menu and use
the arrow keys to move the cursor to the Format column. Press
Enter.
NOTE: Formatting will default the drive to a 512-byte
sector size even if the drive had previously been formatted to
another sector size.
MT/Sec Configuration
[async/5/10/20/40/80/
l60] Indicates the maximum synchronous data transfer rate of the adapter
in megatransfers per second. Can be changed to a lower transfer rate.
The default value is 160.
MB/Sec Configuration
[async/5/10/20/40/80/
160/320] Indicates the maximum synchronous data transfer rate of the adapter
in megabytes per second corresponding to the width and transfer rate
settings that follow. The default value is 320.
Data Width Configuration
[8/16] Displays the maximum data width of the adapter in bits. Can be
changed to narrow width. The default value is 16.
Scan ID Configuration
[Yes/No] Indicates whether to scan for this SCSI identifier at boot time. Utilizing
this setting allows you to ignore a device. This decreases boot time by
disabling inquiry of unused SCSI identifiers. The default value is Yes.
Set this option to No if there is a device that you do not want to be
available to the system. Also, on a bus with only a few devices
attached, you can speed up boot time by changing this setting to No
for all unused SCSI IDs.
Scan LUNs
> 0 Configuration
[Yes/No] Indicates whether to scan for Logical Unit Numbers (LUNs) greater
than zero for a device. LUN 0 is always queried. Use this option if a
multi-LUN device responds to unoccupied LUNs or if it is desired to
reduce the visibility of a multi-LUN device to LUN 0 only. The default
value is Yes.
Set this option to No if you have problems with a device that responds
to all LUNs whether they are occupied or not. Also, if a SCSI device
with multiple LUNs exists on your system but you do not want all of
those LUNs to be available to the system, set this option to No. This
will limit the scan to LUN 0.
Disconnect Configuration
[On/Off] Indicates whether to allow a device to disconnect during SCSI
operations. Some (usually newer) devices run faster with disconnect
enabled, while some (usually older) devices run faster with disconnect
disabled. The default value is On.
SCSI
Timeout Executable
[0-9999] Indicates the maximum allowable time for completion of a SCSI
operation in seconds. Since timeouts provide a safeguard that allows
the system to recover should an operation fail, Dell Computer
recommends that a value greater than zero be used. A value of zero
allows unlimited time for an operation to complete and could result in
the system hanging (waiting forever) should an operation fail. The
default value is 10.
