Troubleshooting Information
This chapter provides guidelines for troubleshooting the controller, cache module, and
external cache battery (ECB). See enclosure documentation for information on
troubleshooting enclosure hardware, such as the power supplies, cooling fans, and
environmental monitoring unit (EMU).
12 HSG80 Array Controller ACS Version 8.6 Troubleshooting Reference Guide
Typical Installation Troubleshooting
Checklist
The following checklist identifies many of the problems that occur in a typical installation.
After identifying a problem, use Table 11 to confirm the diagnosis and fix the problem.
If an initial diagnosis points to several possible causes, use the tools described in this
chapter and then those in Chapter 2 to further refine the diagnosis. If a problem cannot be
diagnosed using the checklist and tools, contact a Compaq authorized service provider for
additional support.
To troubleshoot the controller and supporting modules:
1. Check the power to the enclosure and enclosure components.
Are power cords connected properly?
Is power within specifications?
2. Check the component cables.
Are bus cables to the controllers connected properly?
For BA370 enclosures, are ECB cables connected properly?
3. Check each program card to make sure the card is fully seated.
4. Check the operator control panel (OCP) and devices for LED codes.
See "Flashing OCP Pattern Display Reporting" on page 111, and "Solid OCP Pattern
Display Reporting" on page 113, to interpret the LED codes.
5. Connect a local terminal to the controller and check the controller configuration with
the following command:
SH OW THIS_CONTROLLER FULL
Make sure that the ACS version loaded is correct and that pertinent patches are
installed. Also, check the status of the cache module and the supporting ECB.
In a dual redundant configuration, check the "other controller" with the following
command:
SH OW OTHER_CONTROLLER FULL
Troubleshooting Information 13
6. Use the fault management utility (FMU) to check for Last Failure or "memory system
failure" entries.
Show these codes and translate the Last Failure Codes they contain. See Chapter 2,
"Displaying Failure Entries" and "Translating Event Codes" sections.
If the controller failed to the extent that the controller cannot support a local terminal
for FMU, check the host error log for the Instance or Last Failure Codes. See
Chapter 5 and Chapter 6 to interpret the event codes.
7. Check device status with the following command:
SHOW DEVICES FULL
Look for errors such as "misconfigured device" or "No device at this PTL." If a device
reports misconfigured or missing, check the device status with the following
command:
SHOW device-name
8. Check storageset status with the following command:
SHOW STORAGESETS FULL
Make sure that all storagesets are normal (or normalizing if the storageset is a RAIDset
or mirrorset). Check again for misconfigured or missing devices using step 7.
9. Check unit status with the following command:
SHOW UNITS FULL
Make sure that all units are available or online. If the controller reports a unit as
unavailable or offline, recheck the storageset the unit belongs to with the following
command:
SHOW storageset-name
If the controller reports that a unit has lost data or is unwriteable, recheck the status of
the devices that make up the storageset. If the devices are operating normally, recheck
the status of the cache module. If the unit reports a media format error, recheck the
status of the storageset and storageset devices.

Significant Event Reporting
Controller fault management software reports information about significant events that
occur. These events are reported by:
s Maintenance terminal displays
s Host error logs
s OCP LEDs
Some events cause controller operation to halt; others allow the controller to remain
operable. Both types of events are detailed in the following sections.
Reporting Events That Cause Controller Operation to Halt
Events that cause the controller to halt operations are reported three possible ways:
s a FLASHING OCP pattern display
s a SOLID OCP pattern display
s Last Failure reporting
Use Table 12 to interpret FLASHING OCP patterns and Table 13 to interpret SOLID (ON) OCP
patterns. In the Error column of the solid OCP patterns, there are two separate
descriptions. The first denotes the actual error message that appears on the terminal, and
the second provides a more detailed explanation of the designated error.
Use the following legend to interpret both tables as indicated:
s = reset button FLASHING (in Table 12) or ON (in TABLE 13)
= reset button OFF
q = LED FLASHING (in Table 12) or ON (in TABLE 13)
= LED OFF
NOTE: If the reset button is FLASHING and an LED is ON, either the devices on the bus that
corresponds to the LED do not match the controller configuration, or an error occurred in one of
the devices on that bus.
Also, a single LED that is turned ON indicates a failure of the drive on that bus.
Troubleshooting Information 1 11
Flashing OCP Pattern Display Reporting
Certain events can cause a FLASHING display of the OCP LEDs. Each event and the resulting
pattern are described in Table 12.
IMPORTANT: Remember that a solid black pattern represents a FLASHING display. A white
pattern indicates OFF.
All LEDs FLASH at the same time and at the same rate.
