STEP 4: Prepare the RAID Subsystem

Action Serial Line (CLI) steps
✔
Set the controllers to
multibus failover mode
HS***> set nofailover

manually restarted by momentarily depressing the reset
button on the controller’s front panel
.
HS***> set multibus copy=this
The controllers will restart in multibus mode
Verify that the controller
mode was changed to
multibus failover
HS***> show this
HS***> show other
Prefer each storage unit
to “this” or the “other”
controller. Cycle power on
the RAID cabinet for the
new settings to take effect
HS***> show units
HS***> set
(unit#) preferred=this
- or -
HS***> set
(unit#) preferred=other
STEP 5: Prepare and Install Additional Adaptec AHA 2944UW
NOTE
You must assure that the connection between host adapters
on both servers is consistent. Use the PCI slot numbering
on your servers as a guide. The adapters on each server
that connect to one controller should be in the same PCI
slot in each server. If it is not possible to install the adapters
in the same slot in each server, you must install them in
sequence. For example, the first adapters installed in each
server must connect to the same controller.
Adaptec AHA 2944UW BIOS Settings:
