Collect a Trace

When in Normal Mode, the Hitachi Unified Storage system allows the collection oftrace information three ways: Simple Trace,CTL Alarm Trace. When inMaintenance mode you can collect the Full Dump.

The information is stored in the cache during normal operation. Before performingeither operation, the user should be aware of the size of the binarydump file thatwill be written to the hard disk of the connected host PC.

Simple Trace: Collects as a .dat file. It can take almost 7-9 minutes to collect thetrace. The Simple Trace can also be collected from Storage NavigatorModular 2.

CTL Alarm Trace The CTL Alarm Trace is collected in the normal mode or themaintenance mode of the Web Tool. For connecting to the WEB, amaintenance PC terminal with Browser installed is necessary.

Simple Trace Dump

Use the normal or maintenance mode with the Web Tool to download the traceinformation and configuration information from the controller to the browserterminal. You can collect a simple trace while the device is running. You can alsocollect it when the ALARM LED(red) is lit on the device. The Simple Trace functionis performed using the Web Toolin either Normal or Maintenance mode.The information of both controllers can be collected from one controller. Therefore,this function does not need to be performed from both controllers. You can collect asimple trace while the device is running. You can also collect it when the ALARM

LED(red) is lit on the device.

Simple Trace needs to be collected from both controllers.

1. Turn off the browser pop-up blocker, if enabled.

2. In the left panel, click the Simple Trace link.

What happens when you open the file?

What would you do with the trace file?

________________________________________________________________________

CTL Alarm Trace Dump

The CTL Alarm Tracefunction is performed using theWeb browser in eitherNormal or Maintenance mode. It collects detailed information about a controllerthat has entered a blocked state and outputs the information to the host systemusing a binary file. The CTL alarm trace can be collected after recovering theblocked controller.

Since CTL Alarm trace information is taken over from a blocked controller by the

replaced controller, it can be collected after the replacement of a blocked controller.The information can be collected from one controller at a time. A binary file isgenerated for each controller and the default names are:

Controller 0 = ctla_trc0.dat

Controller 1 = ctla_trc1.dat

1. In the panel at far left, click the CTL Alarm Tracelink.

7/22/2019 TCI2109 Lab Guide v2-0

31/126



Note: Since your subsystem has not experienced a controller blockage, traceinformation has not been collected and you cannot select one of thecontrollers and perform the dump. If blockage trace information wasavailable, the CTL Alarm Trace window would display additionalinformation and you could select a controller and continue the process.

2.If you previously turned off the pop-up blocker, turn it back on.

3.Closeyour browser.

This ends the guided portion of the lab project.

If you want to go back and practice what you have learned, feel free to do so, butkeep in mind that you need to complete the review questionsand have themready for review when the class reconvenes in the classroom.

Make sure you leave the system in the same state that it was in at the end of theguided portion of the lab project this insures that the system will be in a state

that supports the following lab projects.Note: As software products are enabled, the left side menu of the Web browser

screen will list the individual products. At the moment, your screenshould not have any enabled products listed. You should plan to return tothe Web browser to verify that the products are listed as you enable themduring the following lab projects.

Full Dump

Save the files collected from different controllers into different directories, or name

them differently so you can see which controllers they were collected from.

Press the Resetbutton on both controller and take the contollers to MaintenanceMode (please note that in Maintenance Mode all host I/O is stopped. Do not do thison a production HUS that is working fine.)

Because the two LUNs are mapped to both host groups that your server has access to,the server thinks it has access to four LUNs two LUNs on both paths.

Install Hitachi Dynamic Link Manager

Note: The lab project assumes your management server has been loaded with animage that contains images of all the software that is required to complete thelab projects of this course.

An alternative method for obtaining the various software applications is fromthe education departments software share server. The address of this serverwill be supplied to you by your instructor.

The installation of Dynamic Link Manager modifies the servers I/O drivers sothat only one path is displayed for each LUN.

3. Drill to the following directory of your management server:
