Other Functions
Two helpful functions for using the Redundancy Manager graphical user
interface (GUI) are Refresh and Rescan.
Refresh
Refresh (
F5
) updates information on the GUI screen, checks for path failures
and path changes, and displays the current configuration. The GUI will not
update automatically. The changes that you have made will not be saved. Use
refresh to update the main screen to see the current configuration or to see if a
failure has happened in the system. Refresh does not affect any processing or
interrupt any of the system’s functions.
Rescan
Rescan is used to check for new host bus adapters and array controllers and
after adding and removing physical drives. Use rescan after a hot-swap of host
bus adapters or array controllers and after adding or removing physical drives.
NOTE:
For every hot replace, a rescan should be run on each machine in a cluster.
1.
Select Feature
s
from the Main screen.
2.
Select Rescan from the Features menu.
RAID Array 4000 Controller Hot Replace
In an HA/F200 cluster an RA4000 Controller can be replaced in the
RA4000/4100 without powering down the storage system or taking the cluster
“off-line.” This is called “hot replace.”
1.
Identify which controller needs to be replaced from the Compaq
Redundancy Manager screen. Simply remove the fiber optic cable, and
GBIC from the RA4000 controller and remove the RA4000 controller
out of the system. You can remove the active RA4000 controller
provided that the storage system has a standby RA4000 controller ready
for the failover operation.
2.
Insert the replacement controller and GBIC then reconnect the fiber
optic cable.
3.
Perform the Rescan operation to have Redundancy Manager identify the
new RA4000 controller.
