Chapter 11 Sun Enterprise Network Array Test(enatest)

enatest is used to provide configuration verification, fault isolation, and repair validation of the Sun Enterprise Network Array.

The Sun Enterprise Network Array is a high availability mass storage subsystem consisting of:

  • SCSI fibre channel protocol host adapters with dual 100-Megabyte FC-AL ports.

  • A disk enclosure.

  • A Front panel display for configuration information.

  • Up to two interface boards in the enclosure, which provide FC-AL connections to the enclosure and also provide status information and control of the conditions within the enclosure.

  • Other field-replaceable units (FRUs) within the enclosure include power supply units, fan trays and backplane.

enatest detects all Sun Enterprise Network Array enclosures connected to the host and collects relevant configuration information. Figure 11-1 shows the Options menu which contains a sample configuration listing and test parameters. Table 11-1 describes the extent of the test coverage and provides samples of the configuration information that is displayed.

Description

Host Connections

enatest searches for all the active and inactive connections between the host and the enclosure and reports the number of existing active connections. If the VERBOSE mode is enabled, the socal port on the host side and the GBIC port on the enclosure side is reported for each active connection. The test also diagnoses any inactive connection(s) and reports the possible causes for the failure. The test will fail if there are one or more inactive connections. See the section on "Fault Isolation Capability""

for more information.

Sample Output:

SUNWvts.enatest.1010 06/05/97 13:48:53 enatest ses0 VERBOSE:

"MYBOX: Lower-Right GBIC connected to host via /devices/sbus@1f,0/SUNW,socal@0,0:1"

SUNWvts.enatest.1006 06/05/97 13:48:53 enatest ses0 VERBOSE:

"MYBOX: Interface Board (Bottom one in the enclosure) detected to be installed

and OK"

SUNWvts.enatest.6023 06/05/97 13:48:53 enatest ses0

ERROR: "MYBOX: Cannot communicate with the enclosure via

/devices/sbus@1f,0/SUNW,socal@0,0:0; possibly connected to Lower-Left

GBIC in the enclosure"

Probable_Cause(s):

(1)Signal too low at the GBIC module in the enclosure

(2)Faulty cable or cable disconnected

(3)Faulty GBIC module on the host side

Recommended_Action(s):

(1)Ensure the cables are properly connected

(2)Please contact your service representative

SUNWvts.enatest.2006 06/05/97 13:48:53 enatest ses0 INFO:

"MYBOX: Number of connections to the host: 1"

Disk Access

During the testing, each disk is accessed through each active connection leading to that disk. The enatest opens partition 2 on the disk and reads 512 bytes of raw data. If there are any failures, the test tries to isolate the fault to either an enclosure element, the cable, the host adapter card or the OE module on the host adapter. See the section on "Fault Isolation Capability""for more information.

Enclosure Status

The status of the enclosure is obtained by querying the SCSI Enclosure Services (SES) device in the enclosure. Detailed information regarding the status of the elements within the enclosure is reported. The test fails if a critical condition is detected in the enclosure. The table below shows how the status information is reported.

Description

Enclosure Services Functional Test

(General Description)

Certain control operations are performed on devices in the enclosure through the SES device and verified that the operation was performed successful. This functional test involves the following steps:

(a) Perform control operation.

(b) Verify control operation was successful.

(c) Restore state to what it was before (a).

(d) Verify restore operation was successful.

The test will fail if any one of the above steps fails.

This test targets the Disks and the Fans in the enclosure.

Enclosure Services Functional Test

(Detailed disk test description)

(a) Control Operation: Each port of the disk is toggled from its original state: a port that was originally connected will be bypassed and vice-versa.

(b) Verify Control Operation: This is done in two ways. First, the new status of the disk ports is verified by reading the status through the SES device. The test will fail if the status read back does not reflect the change. Next, disk access is attempted through the port that was originally connected but has now been bypassed. The test will fail if the access attempt is successful.

(c) Restore State: The port states are restored to what they were before the Control Operation.

(d) Verify Restore Operation: This is done in two ways. First the status of the disk ports is verified by reading the status through the SES device. The test will fail if the status read back does not reflect the change. Next, disk access is attempted through the port that have been reconnected. The test will fail if the access attempt is unsuccessful.

Enclosure Services Functional Test (Detailed Fan test description)

(a) Control Operation: The speed of each fan is toggled. Possible speeds are HIGH and LOW.

(b) Verify Control Operation: The status is read back through the SES device and the speeds are compared. Failure to vary the speed in this case will result in an INFO message indicating that the fan speed could not be changed but does not result in a test failure. This is because SES can ignore fan speed change requests if required because of existing ambient temperature conditions.

(c) Restore State: Restore the fan speed to the original speed.

(d) Verify Restore Operation: This is similar to the Verify Control Operation step above.

Fault Isolation Capability

In the case of a failure, the test aids in fault isolation by reporting the possible cause(s) of failure. The fault isolation capability varies depending on the nature of the fault and the system configuration. enatest can detect and isolate hard faults. The following table shows the fault isolation capability for different configurations. A Yes indicates that fault isolation capability is available for that component in that configuration and a No indicates lack of fault isolation capability for that component in that configuration.

Description

Connection Test

In this mode, the host connections and the status

of the enclosure are checked. The test fails if there are any broken

connections or if a critical enclosure condition is detected.

Non-critical conditions result in a warning. A sample of the output follows.

The disks will be accessed only if this option is enabled.

disks

This argument consists of a ":" separated list of disks contained within this enclosure, that the test will attempt to access if the disks_access option is enabled. If this option is absent the test will access all the disks that it can find in the enclosure.

esfunc

The Enclosure Services Functional Test will be performed only if this option is enabled.

Note -

64-bit tests are located in the sparcv9 subdirectory: /opt/SUNWvts/bin/sparcv9/testname. If a test is not present in this directory, then it may only be available as a 32-bit test. For more information refer to "32-Bit and 64-Bit Tests".
