Rescanning the Controller
When you make a change by physically adding or removing drives or units,
you can have 3DM2 rescan the controller to update the list of units and
available drives shown on the
Maintenance page.
This is useful in a variety of circumstances. For example, if you add new
drives to the controller, you can make them available by rescanning the
controller. Or if you turn on an enclosure after turning on your computer, you
can use rescan to make the controller see the drives.
Rescanning checks all ports on the controller. It then updates the status of all
attached disks, so if error conditions have been fixed, the status is updated to
reflect that. For more details about how the Rescan feature works, see the
information in the 3DM2 Reference section, under “Maintenance page” on
page 208.
To rescan the controller through 3DM2
1 In 3DM2, choose Management >> Maintenance .
2 On the Maintenance page, click Rescan Controller .
3DM2 scans the controller for information about units and drives, and
updates the information shown on the
Maintenance page.
To rescan the controller through 3BM
1 From the main 3BM screen, press Alt-r.
You are warned that any configuration changes you have made in 3BM
will be lost.
