Configuration Functions

The Status dialog box for controllers with 7.01 and later firmware has the following
additional information not displayed for the controllers with 6.14 firmware:
• Drive Speed (in RPM)
• WWN (worldwide name)
The Modify Disk Device Status dialog box allows you not only quickly view status of
the drives, but also to define hot spares. Each drive in Figure 3-3 or Figure 3-4 maps to
the same physical row and column of the disk drive chassis. If you are also using
expansion enclosures, additional drive matrices are displayed for each chassis attached
to the RAID enclosure.
Operation
Click on a button (or buttons) to change the drive state, then click OK at the bottom of
the screen to activate the changes. You would typically use the buttons as follows:
• Click ON-LINE to put a drive into the online state.
• Click HOT SPARE to turn one or more drives into hot spares.
• Click UNCONFIGURED to change the state of a drive from online to dead (a dead
drive acts as though it is not even plugged in).
Changes are effective immediately, and no reboot is required. It is safe to perform these
changes at any time (providing you are not taking a mounted LUN offline by marking its
drives as
UNCONFIGURED , of course).
When you click OK after having made your selections, you are returned to the main
menu. If you click Reset Screen , all radio buttons that you have changed are set back to
their previous states.
