Completing the process
This section provides a procedure for ensuring that the FRU components installed in the replacement
controller enclosure chassis function properly.
1.
Reconnect data cables between devices, as needed, to return to the original cabling configuration:
• Between cascaded enclosures.
• Between the controller and peripheral or SAN devices.
• Between the controller enclosure and the host.
2.
Reconnect power cables to the controller enclosure. See
3.
Turn on the power switch to each power supply module if they are equipped with power switches.
NOTE:
For powering-on AC PSUs with or without a power switch, and DC and AC PSUs with a power
switch, see
Verifying component operation
1.
Restart system devices in the following sequence. Allow time for each device to complete its Power On
Self Tests (POST) before proceeding:
a.
Expansion enclosure(s)
b.
Controller enclosure
c.
Host (if powered down for maintenance)
2.
Perform a rescan to force a fresh discovery of all expansion enclosures connected to the controller
enclosure. This step clears the internal SAS layout information, reassigns enclosure IDs, and ensures the
enclosures are displayed in the proper order. Use the CLI, the SMC, or RAIDar to perform the rescan:
To perform a rescan using the CLI, enter the following command:
rescan
You can set a CLI preference to use v3 or v2 terminology in command output and system messages.
See TIP bullets regarding CLI “default management mode” and “current management mode”
To rescan using the SMC (v3):
a.
Verify that both controllers are operating normally.
b.
Do one of the following:
• Point to the
System
tab and select
Rescan Disk Channels
.
• In the
System
topic, select
Action
>
Rescan Disk Channels
.
c.
Click
Rescan
.
To rescan using RAIDar (v2):
a.
Verify that both controllers are operating normally.
b.
In the Configuration View panel, right-click the system and select
Tools
>
Rescan Disk Channels
.
c.
Click
Rescan
.
See “Correcting enclosure IDs” in the Setup Guide for additional information.
Using LEDs
View LEDs on the front and rear of the enclosure (see “LED descriptions” within the
AssuredSAN 4004
Series Setup Guide
for more information).
Verify front panel LEDs:
•
Verify that the Enclosure ID LED (located on the left ear) is illuminated green.
•
Verify that the FRU OK and Temperature Fault LEDs are illuminated green, and that the Fault/Service
Required LED is off (all three LEDs are located on the right ear).
•
For LFF disks, verify that the Power/Activity LED (bottom LED on front of disk) is illuminated green or
blinking green.
Remove the enclosure bezel to view disk LEDs. Attach the bezel when finished viewing disk LEDs.
