8. Reconnect all communication cables (Fibre Channel/iSCSI/SAS, management, serial) to the appropriate
connectors on the replaced RAID Controller.
Note
If you have replaced only one Controller in a dual-Controller unit, skip to step 10.
9. If you have replaced the Controller in a single-Controller unit or
both
Controllers in a dual-Controller unit,
press and hold the
SW0
switch for approximately 4 seconds to power the unit on.
10. If you have replaced the Controller in a single-Controller unit or
both
Controllers in a dual-Controller unit,
clone the Controller settings from a disk by doing one of the following:
On a computer attached to the same Ethernet network as the Controller, launch the Nexsan IP
Configuration utility (included with Nexsan Storage Tools). Select the storage system and choose the
option to clone Controller settings from disk.
Connect a serial cable to your device and log in with a telnet program (115200 baud, 8 data bits, 1 stop
bit, no parity, no flow control). At the prompt, choose the option to clone Controller settings from disk
11. Wait 1–2 minutes for the new Controller to boot.
12. In the graphical user interface (GUI), go to the
Home
page and verify that the status bar for the new
RAID Controller is green. See the
Nexsan High-Density Storage User Guide
for more information.
13. If necessary, restart or reconnect your hosts and verify that all volumes are working as expected.
