Cautions for the HP_RDI Alarm on OptiX OSN9500

Identification method:
1. The source version  is V100R003 or V100R004.
2. The EXCL board is used and lower order services access to the 1+1 linear MS.
3. Run the: cfg-get-1j1lmsp-lxcoptmz command. "Unregistered command" is displayed or the result is "disable".
4. Lower order services access to the 1+1 MSP protection path earlier than the working path. Run the :cfg-get-lmsbdmap:pgi (pgid indicates the ID of the 1+1 linear MSP group) command. The timeslots for the protection and working paths are A and B respectively. Run the : dbms-query: " Cfgmapxc.dbf ", mdb command. It is found that A is earlier than B. The following example shows that timeslot 1 for port 2 of the board in slot 17 priors to timeslot 1 for port 1 of the board in slot 17.

Total records :6

If the preceding four conditions are all met, after the version is upgraded to V100R005 or V100R006 earlier than V100R006C05SPC203, the HP_RDI alarm is inserted in downstream devices (the corresponding inspector is available and preferred).

[Root Cause]
The optimization function for lower order service configuration on the 1+1 liner MS is not supported by earlier versions, while that is supported by V100R005 and V100R006 by default. In an earlier version, if lower order services access to the 1+1 protection path earlier than the working path, after the version is upgrade to V100R005 or V100R006 earlier than V100R006C05SPC203, the system control board first recovers the services that access to the 1+1 protection path by default and performs lower order optimization when recovering the services that access to the 1+1 working path. Therefore, the lower order services of both protection and working paths use the same higher order point on the EXCL board, while the higher order point of the working path is idle, so the EXCL board inserts the HP_RDI alarm in the downstream to the working path.
[Impact and Risk]
After the related version is upgraded to V100R005 or V100R006 earlier than V100R006C05SPC203, the downstream devices receive the HP-RDI alarm. Services are faulty when some switching devices receive the HP_RDI alarm, causing service interruption.

[Measures and Solutions]
Preventive measures:
Use either of the following methods:
1. Delete the MS before the upgrade, and configure the MS after the upgrade.
2. Deactivate and activate the faulty service before the upgrade.
Solution:
Upgrade the NE to V100R006C05SPC203 or a later version.
[Inspector Applicable or Not]
Update the test case package to the latest one.
Path: Upgrade pre-check/ Checks whether the HP_RDI will be triggered after lower order services are accessed into 1+1 LMS and V100R004 is graded to V100R006C03SPC200

Anti-X & Zorin 9

Anti-X 14.2 is a pretty good distro, have been setting it my specifications.

When you install a new browser, iceweasel does not work. Then you have no access to setting up a printer. Anti-X is great for using g-parted and also unetbootin to make usb sticks and it is fairly quick. This distro is easy to install and run for a beginner or someone who is new to Linux

Zorin 9 is easy to set up and seems to run fairly smooth, that is what I'm using now. It's stable with no glitches that I can find, so I reccomend this desktop over ubuntu or other desktops I have used. That said I have been using Linux for about six months, so guess I would be what you call a "NEWBIE" to the system, but it sure beats the heck out of paying Microsoft high dollar for a system that need upgraded every couple years that has become confusing to customers.

Please Note That Data Boards May Fail to Start Up After an Upgrade on OptiX OSN 550/500

Summary:
0.03% to 0.1% of certain models of data boards and central switching boards with the basic BIOS version of 1.21 or earlier on OSN 550/500 NEs fail to start up after the NEs are upgraded, which results in the rollback of the NE version. The issue is solved after the boards are replaced.

Huawei OSN 550Trigger conditions:
This problem may occur if the following conditions are met at the same time:
An NE is upgraded.
The NE uses one of the following boards: TNH1EM6T/F, TNM1EF8F, TNH1CSHDA/B, TNM1PCXLG, TNM1PCXX, TNM1PCXLX, TNM1PCXGB, or TNM1PCXGA.
The basic BIOS version of the board is 1.21 or earlier.
Symptom:
The faulty board stays in the BIOS state after an upgrade and does not start up. The fault is cleared after the NE version is rolled back.
Identification method:
1. Query the version

QQ截图20140728093554

2. After an upgrade, the STAT indicator on the board is red and the other indicators are off, which indicates that the board stays in the BIOS state and fails to start up. The board starts up after the NE version is rolled back.
The following interfaces are displayed in the case of an automatic rollback after an upgrade failure on the U2000.When both of the preceding conditions are met, the fault can almost be identified.
[Root Cause]
On the basic BIOS of version 1.21 or earlier, the time sequence of the CPU adder is not the optimal configuration. As a result, there is a low possibility that the board fails to start up after an upgrade.
[Impact and Risk]
The board does not start up after an upgrade, which results in service interruptions. The fault is cleared after the NE version is rolled back.
[Measures and Solutions]

The fault is automatically cleared after the NE version is rolled back.

Solution:

The basic BIOS of boards on OSN 500/550 cannot be upgraded online. If the fault occurs on an NE during an upgrade, replace the board with a new board with the basic BIOS version of 1.22 or later.
Material handling after replacement:
Return the replaced board to Huawei, if the board supplied by thunder-link.com, then please contact your sales representative.

 

It's Free, But It's Broken

Google Abandonware

 
About six months ago I noticed that one of the portfolios I was tracking using Google Finance Portfolio suddenly started reporting wrong historical data for nearly all of the equities in the portfolio. I clicked on the "Report a problem" link at the bottom of the page and used the form to send off a detailed description of the problem off to Google.

I never received a reply, of course. I've sort of come to expect that when reporting issues with free Google resources. So, in the mean time I clicked on the link for theGoogle Finance Blog to see if anybody else had reported the problem.

Oh, oh. Here is the top post, dated two years ago:

Posted by Karolina Netolicka, Product Manager

Thanks to everyone who has been a loyal reader of the blog over the last five years. After some consideration, we've realized that we're just not generating enough content here to warrant your time, so we won't be posting here any longer.


Instead, we'll start contributing to the Inside Search blog, so tune in there for updates on Google Finance.

 


Looking through the referenced Inside Search Blog  blog turned up no discussion on the broken Google Finance portfolio tracker, but a more general search turned up plenty of discussions on the topic, such as this one. Bottom line: Google Finance is broken, and unsupported.
 
More recently, about three weeks ago I went over to the Google Finance Stock Screener using, as always, Google's Chrome Browser on my Linux box, and I found it to broken as well, and fairly recently. I had used it just one month prior.
 
Digging a little deeper, I realized that their stock screener page itself wasn't really broken; it worked fine when using Firefox. However, the page was not being rendered properly by the Google Chrome browser; elements of the page overlapped each other, making the page unusable.
 
Here's how the screener page is supposed to look (Firefox):
 
 
 
And here's how it looks in Chrome:
 
 
 
The slider elements overlay the the numeric input boxes on the right making it impossible to set screener selection criteria.
 
Bottom line: it is probably not a good idea to include Google products in any mission-critical applications, because you simply never know if they will continue to be supported in the future.

Excellent Free Distraction-Free Tools for Writers

Fans of the typewriter remain a vehement group. They view the typewriter as something really special, a tool which makes the connection between languages. One of the attractions of a typewriter is that it offers a distraction-free alternative of modern day methods for producing a document. They challenge the writer to concentrate on what really matters - the content. They force the writer to think.

In many countries, the typewriter has been largely consigned to history by the computer. Yet, the computer is jam-packed with distractions. The desktop with its cluttered interface, the chatter of social media, the almost limitless content of the internet, the chirping email notifications, the list of distractions is endless. When writing, concentration is vital. Fortunately, there are computer applications which are designed to offer a distraction-free environment, to ensure the writer has mental clarity, by not being distracted by the operating system and a cluttered interface.

Here is my take on the finest distraction-free applications to help you focus on writing without interruption. Each of the applications run in Linux, most are available as desktop applications.

What I want from a Linux laptop

 

My perfect Linux laptop would be one that can be used in a ultra low power mode and have the option of being charged from a small solar panel of merely 10 Watt. The only slightly unique thing would be the E-ink screen cover. To be used when reading or writing text in the low power mode. Additionally it should have HDMI and usb input to connect a raspberry pi to the screen and keyboard. The keyboard ought to be one of the old types since my error rate is rather high with flat keys.
