5. Check the status of the virtualization engine using one or more of the following

methods:

■

Storage Automated Diagnostic Environment device monitoring reports

■

Run the SEcfg script, which displays and shows the virtualization engine

■

Refer to the LED status blink codes in Chapter 7.

6. Quiesce the I/O along the path to be tested as follows:

■

For installations using VERITAS VxDMP, disable

vxdmpadm

■

For installations using the Sun StorEdge Traffic Manager software, unconfigure
the Fabric device.

■

Refer to “To Quiesce the I/O” on page 8

■

Halt the application.

7. Test and isolate the FRUs using the following tools:

■

Storage Automated Diagnostic Environment diagnostic tests (this might require
the use of a loopback cable for isolation)

■

Sun StorEdge T3+ array tests, including

t3test

(1M),

t3ofdg

(1M), and

t3volverify

(1M), which can be found in the Storage Automated Diagnostic

Environment User’s Guide.

Note –

These tests isolate the problem to a FRU that must be replaced. Follow the

instructions in the Sun StorEdge 3900 and 6900 Series Reference Manual and the Sun
StorEdge 3900 and 6900 Installation and Service Manual for proper FRU replacement
procedures.
