Ever wonder why your storage path goes into a “Dead” state?

Staff Engineer Nathan Small has authored a new Knowledgebase article which describes most of the scenarios that lead to this condition.

There basically three reasons your storage path can go into a “dead” state:

  1. The ESX Storage stack determines path is dead due to TEST_UNIT_READY command failing on probing
  2. The ESX Storage stack receives a Host Status of 0×1 from HBA driver:
    a. Remote array port has timed out
    b. Remote array port has dropped from the fabric (RSCN)
    c. Remote array port has closed IP connection
  3. The ESX Storage Stack marks path as dead after PDL check condition returned by Storage array

Check out Nathan’s excellent article on the topic here: Understanding how paths to a storage/LUN device are marked as Dead (2062592)

One thing that catches a few customers up is the process of installing async drivers in their ESXi host … We have a KB article on the topic here, but there is more than one method to choose from and preparation steps involved. Since these steps might seem a little tricky, we decided a quick, live video explaining the topic might help many of you.

We called upon Kiwi Ssennyonjo to walk us through the salient points.

Again, the full KB article can be found here: Installing async drivers on ESXi 5.0/5.1/5.5 (2005205)

VMware ESXi 5.5 allows you to upgrade from previous ESXi versions using several different methods. These methods are described and outlined in VMware Knowledge Base article Methods for upgrading to ESXi 5.5 (2058352).

In this new video tutorial we demonstrate how you can upgrade from VMware ESXi 5.1 to ESXi 5.5 using the Interactive Installer that is supplied on the ESXi 5.5 Installation Media. We’ll show you the step-by-step procedure for performing a basic upgrade from ESXi version 5.1 to version 5.5 using the Interactive Installation method, however the instructions apply to older versions of ESXi as well.

This video assumes that you have read the documentation for the update you are applying. For more information, see the VMware vSphere 5.5 Release Notes and the vSphere Upgrade Guide.

For information relating to the other upgrade methods, see VMware Knowledge Base article Methods for upgrading to ESXi 5.5 (2058352).

Have you heard about VMware’s new associate certifications?

Dena Tooma, a technical writer at VMware says it took less than a day to both study and write her VCA exam. Watch as she tells us how she has more confidence dealing with her peers now that she understands more of the terminology and concepts around VMware products. Certification is not just for the hard-core IT nerds anymore.

Whether you’re looking for your first certification or branching into new areas of expertise, VMware Certified Associate certifications are the easiest to achieve, giving you a firm footing on which to grow and document your expertise. They are also a great opportunity for non-technical colleagues to learn about VMware technology.

If you are interested in becoming a VMware Certified Associate (VCA), check for certification requirements here: www.vmware.com/certification

Manually collecting diagnostic logs from the Android VMware switch

 Allgemein, Cloud, Knowledge Base, Updates, VMware, VMware KBTV, VMware Partner, VMware Virtual Infrastructure, vSphere  Kommentare deaktiviert für Manually collecting diagnostic logs from the Android VMware switch
Nov 042013
 

In today’s new video tutorial, we discuss and demonstrate the process for manually collecting diagnostic logs from the Android VMware Switch.

The normal method to collect the logs from a VMware Ready device is using the VMware Horizon Mobile Server console or through the Horizon Workspace console to which the device is connected. However, if the device fails to connect to the server, you may have to collect the logs from the device itself.

This video provides steps to collect the logs from a VMware Ready device on which the VMware Switch application is installed when other methods are not applicable.

For additional information, see VMware Knowledge Base article Manually collecting diagnostic logs from the Android VMware Switch (2058741).

With the vSphere 5.5 release a few weeks back a new feature called Virtual Flash was introduced.

We put together this video which provides an overview of this new Virtual Flash feature and its benefits in a vSphere environment.

In essence, Virtual Flash allows you to accelerate virtual machine performance through the use of local SSD (Solid State) disks, which serve flash memory cache to chosen virtual machines running on the ESXi host. Virtual Flash Read Cache can supply low latency for extreme latency sensitive applications which helps to enable the virtualization of some computer systems/applications previously considered too I/O intensive. Virtual Flash caching is achieved using flash memory in the form of solid state disks (SSDs).

We will be following this video up with some new short and quick tutorials over the next few days which will cover:

  • Allocating Virtual Flash Read Cache to a virtual machine
  • Adjusting the amount of VIrtual Flash Read Cache caching in a virtual machine
  • Disabling Virtual Flash Read Cache caching in a virtual machine
