MAP 5000: Start is an entry point to the maintenance analysis procedures (MAPs) for the
system.
Before you begin
Note: The service assistant
interface must be used if there is no front panel display, for example on the SAN Volume Controller 2145-DH8.
If you are not familiar with these maintenance analysis
procedures (MAPs), first read Using the maintenance analysis procedures.
This MAP applies to all system models. Be sure that you know
which model you are using before you start this procedure. To determine which model you are working
with, look for the label that identifies the model type on the front of the node.
You might be sent here for one of the following reasons:
- The fix procedures sent you here
- A problem occurred during the installation of the
system
- Another MAP sent you here
- A user observed a problem that was not detected by the system
System
nodes are configured in pairs. While you service one node, you can access all the storage managed by
the pair from the other node. With concurrent maintenance, you can remove, replace, and test all
FRUs on one system while the SAN and host systems are powered on and doing productive work.
Notes: - Unless you have a particular reason, do not remove the power from both nodes unless instructed
to do so.
- If an action in these procedures involves removing or replacing a part, use the applicable
procedure.
- If the problem persists after you complete the actions in this procedure, return to step 1 of
the MAP to try again to fix the problem.
Procedure
- Were you sent here from a fix procedure?
- NO
- Go to step 2
- YES
- Go to step 6
- (from step 1)
Access the management GUI. See Accessing the management GUI
- (from step 2)
Does the management GUI start?- NO
- Go to step 6.
- YES
- Go to step 4.
- (from step 3)
Is the Welcome window displayed?- NO
- Go to step 6.
- YES
- Go to step 5.
- (from step 4)
Log in to the management GUI. Use the user ID
and password that is provided by the user.
Go to the Events page.
Start the fix procedure for the recommended action.
Did the fix procedures find an error that is to be fixed?- NO
- Go to step 6.
- YES
- Follow the fix procedures.
- (from steps 1, 3, 4, and 5)
Is the power indicator off? Check to see whether the power LED is
off.
- NO
- Go to step 7.
- YES
- Try to turn on the nodes.
Note: SAN Volume Controller 2145-DH8
does not have an external uninterruptible power supply unit. This system has battery modules
in its front panel instead.
If the nodes are turned on, go to step 7; otherwise, go to MAP 5040: Power SAN Volume Controller 2145-DH8.
- (from step 6)
Does the node show a hardware error?
- NO
- Go to step 8.
- YES
- The service controller for the
system
failed. (The SAN Volume Controller 2145-DH8 does
not have a service controller.)
- Check that the service controller that is indicating an error is correctly installed. If it is,
replace the service controller.
- Go to MAP 5700: Repair verification.
- (from step 7)
Is the operator-information panel error LED
( 4 in Figure 1 or
7 in Figure 2)
illuminated or flashing? Or, is the check log LED ( 6 in Figure 2) illuminated or flashing?
Figure 1 shows the operator-information panel for the SAN Volume Controller 2145-SV1.

- 3 Node status LED
- 4 Node fault LED
- 5 Battery status LED
Figure 2 shows the operator-information panel for the SAN Volume Controller 2145-DH8.

- 3 System-locator button and LED
- 4 Release latch for the light path diagnostics panel
- 5 Ethernet activity LEDs
- 6 Check log LED
- 7 System-error LED
Note: If the node has more than four Ethernet ports, activity for ports 5 and above is not indicated
by the Ethernet activity LEDs on the operator-information panel.
- NO
- Go to step 9.
- YES
- Go to MAP 5800: Light path.
- (from step 8)
For a 2145-DH8 model, is the node status
LED, node fault LED, and battery status LED that you see in Figure 3 all off?
- NO
- Go to step 11.
- YES
- Go to step 10.
- (from step 9)
- (from step 9 )
Is the node fault LED ( 8 in Figure 3) on the front panel of a SAN Volume Controller 2145-DH8
on?
Figure 3 shows the node fault LED.

panel- 7 Node status LED
- 8 Node fault LED
- 9 Battery status LED
- (from step 11)
Is Booting indicated on
the node?- NO
- Go to step 14.
- YES
- Go to step 13.
- (from step 12)
If the boot progress does not advance for more than 3 minutes, the progress
is stalled.
Has the boot progress stalled?
- NO
- Go to step 14.
- YES
- Go to MAP 5700: Repair verification.
- (from step 12 and step 13)
Is the node fault LED, which is the middle of the three status LEDs on
the front panel of a SAN Volume Controller 2145-DH8
, on?
Figure 3 shows the node fault LED.
- NO
- Go to step 15.
- YES
- Complete these steps:
- Note the failure code and go to Node error code overview to complete the repair actions.
- If the node does not have a front panel display, access the service assistant interface via the Technician port for node access and follow the service recommendation presented.
- Go to MAP 5700: Repair verification.
- (from step 14)
Is Cluster Error reported on the
node?
- NO
- Go to step 16.
- YES
- A cluster error was detected. This error code is displayed on all the operational nodes in the
system. The fix procedures normally repair this type of error. Follow these steps:
- Complete the error code repair actions.
- Go to MAP 5700: Repair verification.
- (from step 15)
Is Powering Off,
Restarting, Shutting Down, or
Power Failure reported on the node?
- NO
- Go to step 17.
- YES
- Wait for the operation to complete and then return to step 1 in this MAP. If the progress is stalled after 3 minutes, press
power and go to step 17.
- (from step 16)
Did the
node power off?
- NO
- Complete the following steps:
- Remove the power cord from the rear of the box.
- Wait 60 seconds.
- Replace the power cord.
- If the node does not power on, press power to power on the node and then
return to step 1 in this MAP.
- YES
- Complete the following steps:
- Wait 60 seconds.
- Click power to turn on the node and then return to step 1 in this MAP.
Is there a node that is not a member of a clustered system?
You can tell if a node is not a member of a system because the node
status LED is off or blinking for SAN Volume Controller 2145-DH8
.
- NO
- Go to step 19.
- YES
- The node is not a member of a system. The node might have been deleted during a maintenance
procedure and was not added back into the system. Make sure that each I/O group in the system
contains two nodes. If an I/O group has only one node, add the node back into that system. Then,
ensure that the node is restored to the same I/O group from which it was deleted.
No errors were detected by the system. If you suspect that the problem that is
reported by the customer is a hardware problem, follow these tasks:
- Complete Problem Determination procedures on your host systems, disk controllers, and Fibre
Channel switches.
- Ask IBM remote technical support for assistance.
- (from
step 10)
Can
you access the service assistant interface through the 2145-DH8 technician
port or service IP address, or use a USB flash drive to get satask_results.html?
- NO
- The system software might not be running. Attach a USB keyboard and VGA
monitor to the 2145-DH8 to
see whether the node is stuck booting.
- YES
- Go to step 21.
- (from
step 20)
Can
node error 561 be seen?
- NO
- Follow the recommended action for any node error that can be seen.
- YES
- The system software might not be able to communicate with the battery
backplane.
- Check the connections between the system board and the battery backplane. Then, follow the
recommended action for node error 561.
