IBM Storwize V7000 Upgrade Procedure


I Recently upgraded the firmware on two V7000 Storwize systems. Both went smoothly by using the GUI manager. While one node is being upgraded the other takes over control so there is no downtime. However, there might be a possible performance decrease during the upgrade. After the upgrade I've noticed the error logs are no longer being filled with software errors; which I knew the new firmware was to fix.

Storwize V7000
Download the following files from the www.ibm.com/support website:
      1. The latest IBM Storwize V7000 code level(firmware).
      2. The latest IBM Storwize V7000 Upgrade Test Utility.


The V7000 Upgrade Test Utility can be used to check for known issues which may cause problems during a Storwize V7000 software upgrade.

From the Storwize V7000 Gui Manager:
1. Go to the Configuration>Advanced panel in the GUI
2. Select Upgrade Software
3. Press the Launch Upgrade Wizard button
4. When prompted, upload the upgrade test utility package to the system and click Next
5. When prompted, enter the software version you intend to upgrade to and click Next. This field will be automatically populated with the latest available software version if it is available
6. The following page will contain the results of the upgrade test. Review the output from the upgrade test utility to see if any actions are required before starting the upgrade
  1. If you wish to continue with the firmware upgrade at this time, click Next to proceed with the upgrade process. Otherwise click Cancel to exit the upgrade wizard




The V7000 Code(firmware) upgrade process will take about an hour and a half during which time the fans may run at maximum speed. Check the error logs for entries stating the firmware upgrade has been completed.

During the automatic upgrade process, each node in a system is upgraded one at a time, and the new code is staged on the nodes. While each node restarts, there might be some degradation in the maximum I/O rate that can be sustained by the system. After all the nodes in the system are successfully restarted with the new software level, the new software level is automatically committed.

During an automatic software upgrade, each node of a working pair is upgraded sequentially. The node that is being upgraded is temporarily unavailable and all I/O operations to that node fails. As a result, the I/O error counts increase and the failed I/O operations are directed to the partner node of the working pair. Applications do not see any I/O failures. When new nodes are added to the system, the software upgrade file is automatically downloaded to the new nodes from the Storwize V7000 system.

The upgrade should go smoothly but be sure to check the error logs beforehand and fix any issues.

Also, periodic monitoring of the hardware should be done to inspect cables etc. Check the management GUI which displays the System Health as well a check the performance statistics for processor (CPU) utilization, host and internal interfaces, volumes, and storage pools.

And finally check the ibm support site often to download new firmware when it becomes available so you can start planning and preparing the appropriate 'slight' downtime to apply it.

Lenovo IdeaPad S340-14IIL memory upgrade (Do This)

Do you want to upgrade the memory on your Lenovo IdeaPad S340?
You may be wondering if you can add additional memory? That's what we're here for. This article will detail the steps you can follow to make your laptop run better.
The good news is the S340 is capable of upgrading the memory.
This guide will be specifically for the Lenovo IdeaPad S340-14IIL. Other S340 models will be similar but might come with different amounts of memory. That is, the process will be the same but the specs might be slightly different.


Let's look at the specifications on the S340-14IIL.  It is a 14" laptop that comes with 8GB memory and a 256GB SSD drive. It also has the 10th generation Intel Core Processor.
It is an affordably priced powerful laptop that weighs about 3.5 pounds. It's newly released and so it comes with 3 USB 3.1 ports, one of which is Type-C. The model you own might have more or less memory, but we can access and upgrade them the same way.

Palm Rest Removal - IBM/Lenovo T40/40p, T41/41p, T42/42p

Simple instructions for removing and replacing the palm rest for T4x Thinkpads.

Remove these parts in order to remove the palm rest.
-Remove the battery
-Remove the hard drive
-Remove the keyboard

Turn the Thinkpad over. There are five screws on the lip of the machine covered by black plastic tabs. You will need to remove these tabs, I use a razor blade and then save the tabs to re-apply them. After the tabs have been removed take out the screws and take note of their size and placement. The screw on the right side is a little longer and will need to be put back in the same place. There are also several other screws to remove a little farther up on the machine. They will have a small drawing of a memory chip next to them. These screws are different sizes as well so make note of their placement.



-Turn the Thinkpad over and open the display
-Remove the touchpad connector from the motherboard
-Pull the palm rest toward you slightly and lift it up and out.

5 Rugged Laptops For Students (affordable)

There are many articles about the best laptops for college students. I wanted to find out what are some of the most rugged and affordable laptops for college students. That's what this article is about, I researched and put together a list of laptops capable of standing up to the rigors of college life.

Many manufacturers make rugged laptops but these can get expensive, I wanted to focus on affordable and rugged. A laptop students could afford as well as one that would last. My picks are compact, lightweight and capable. They range from 11inch to 14inch displays and from around $400US to under $1000US.


Which laptop brands are the most durable?
I chose 5 laptops from Lenovo since I am most familiar with these already. Lenovo Thinkpads are tested against 12 military-grade requirements and more than 200 quality checks. These are all Thinkpad branded except for the Lenovo 300e which is still military-grade rated. Check out the Lenovo stress test video and the end of this article.
