Selection Menu Description
The selection menu contains a list of options for performing the various
administrative tasks on the controller and the attached disk array
subsystem(s). The individual options are detailed in the following
descriptions.
Select Adapter
In a system with only one Mylex Disk Array Controller, this selection can be
ignored. If there is more than one controller in the system (up to four are
supported), use this command to select the appropriate controller on which
to perform an action. All actions or commands will be performed only on the
currently selected controller.
Use the Up/Down arrow keys to move the cursor, press <Enter> to select.
The selected controller will be shown in a pink rectangle in the upper right
window below the title bar.
Drive Information
This selection is used to identify a device, its manufacturer, its model
number and its capacity. It also is used to identify the state of the device, as
well as the type and number of errors on a disk drive.
Use the arrow keys to move the cursor block over each connected device.
A sub-window will show specific information on the device.
The Drive Information window displays the states of all devices as follows:
ONL: device online
DED: device killed
SBY: device is a standby (hot spare)
- - - - : device not present
< >: device newly-added
XXXX:device in some other state, such as rebuild
The Drive Information selection also contains a feature that is highly useful
when configuring or troubleshooting an array.
To identify a specific drive, use the arrow keys to position the cursor block
on one of the drives in the Select Device menu, then, press the Insert key.
This will suspend all disk activity and will start flashing the selected drive's
in-use LED. Also, the selected drive will flash on the screen. Pressing any
key at this point will resume normal activity.
