NOTE: This field is executable and must be selected with
the Enter key. You also input the new value with the number
keys from either the keyboard or number pad.
Queue
Tags Configuration
[On/Off] Indicates whether to allow the use of queue tags for a device. This
item specifies queue tag control to higher level device drivers. The
default value is On.
Changing a setting for the host adapter (for example, SCSI ID 7) will change the setting for all Target IDs. The
number of fields displayed requires the menu to scroll left/right in order to display the information. When accessing
this menu online, use the Home/End keys to scroll to columns currently not displayed. The scroll indicator on the
bottom of the menu shows where the cursor is relative to the first and last columns.
Mirroring Properties Menu
The following restrictions were made in order to simplify the IM configuration:
One mirrored boot volume is allowed per system.
One disk drive is required for the boot drive and one disk drive for the mirror drive.
Disks selected for a mirrored boot volume must be connected to the same channel of the same physical
adapter. This adapter must be in the BIOS boot order.
Disks selected must be single-LUN disks that support wide, synchronous transfers, must be SMART enabled,
and must be minimally compliant with SCSI-2 standard.
Removable media devices cannot be used for mirrored volumes.
Different size disks are allowed, but excess space on the larger disk is unusable.
Configuration of volume properties is kept to a minimum.
Default settings are provided for all modifiable fields.
The Mirroring Properties menu is part of the standard BIOS configuration utility. One of the items on the Adapter
Properties menu allows access to a Mirroring Properties menu, which allows creation and configuration of an IM
Volume. An IM Volume exists as soon as two disks have been selected through the Mirroring Properties menu and
the user saves the changes. The Mirroring Properties menu has additional configuration options and displays the IM
volume properties and status.
To select this menu, follow these steps:
1. Select an adapter using the arrow keys while on the Main menu.
2. Press Enter to move to the Adapter Properties menu.
3. Select Mirroring Properties using the arrow keys.
4. Press Enter to move to the Mirroring Properties menu.
