Veeam FastSCP “Agents failed to start” During Copy

February 8th, 2011

Quick fix here for an operational task error I encountered in Veeam FastSCP 3.0.3.  I was trying to copy a file from the VMware vMA 4.1 appliance to a Windows folder using Veeam FastSCP 3.0.3.  In Veeam, the vMA appliance is registered as a Linux server & is recognized in the interface as the server object with the penguin.  In this example, I’m trying to copy /etc/motd to my local C: drive on Windows 7 Ultimate 64 bit:

After a delay of several seconds, the error message is displayed:
Agents failed to start, server “vma41.boche.mcse”, client “localhost” Cannot connect to server [x.x.x.x:2500].

SnagIt Capture

The problem is an iptables daemon which is responsible for blocking communication on port 2500.  The workaround I used is to temporarily disable the iptables daemon as follows:

[vi-admin@vma41 etc]$ sudo service iptables stop
Flushing firewall rules: [ OK ]
Setting chains to policy ACCEPT: filter [ OK ]
Unloading iptables modules: [ OK ]

SnagIt Capture

Immediately after the iptables daemon is stopped, I’m able to copy the file:

Now that my file is copied, I’ll undo the workaround, ensuring the vMA appliance is left in the state I had found it with its firewall rules applied:

[vi-admin@vma41 etc]$ sudo service iptables start
Applying iptables firewall rules: [ OK ]
Loading additional iptables modules: ip_conntrack_netbios_n[ OK ]

SnagIt Capture

Left alone, the workaround would persist until the next reboot.  Other workarounds to deal with this issue in a more permanent fashion would be to open port 2500 or use chkconfig to permanently disable the iptables daemon as follows:

sudo chkconfig iptables off
sudo service iptables save
sudo service iptables stop

VCP4 Exam Cram: VMware Certified Professional (2nd Edition)

February 7th, 2011

DSC04094

Tonight I was grateful to have received from Pearson Education the book VCP4 Exam Cram: VMware Certified Professional (2nd Edition).  The book is authored by Elias Khnaser (Twitter WWW) along with Technical Editors Brian Atkinson (WWW) and my friend Gabrie van Zanten (Twitter WWW).  This 2nd edition is 340 pages in length and ships with a cardboard fact filled cram sheet in the front as well as a CD in the back which contains VCP4 practice exams and an electronic versions of the cardboard cram sheet in case your friends are jealous of your intimate VMware vSphere knowledge and decide to swipe yours.

The book (ISBN-10: 0789740567) includes 10 chapters along with an appendix.  The chapter layout is as follows:

  1. Introducing vSphere 4
  2. Planning, Installing, and Configuring ESX/ESXi 4.1
  3. vNetworking Operations
  4. vStorage Operations
  5. Administration with vCenter
  6. Virtual Machine Operations
  7. vSphere Security and Web Access
  8. Managing vSphere Resources
  9. Monitoring vSphere Resources
  10. Backup and High Availability

There are a very few number of books which focus specifically on the VCP-410 exam.  This one is hot off the presses; published on January 31, 2011.  As such I would expect to find the most recent and relevant vSphere as well as exam information contained within.  Admittedly, I have not read this book cover to cover and have no plans to having passed the VCP4 17 months ago.  However, I have thumbed through several sections admiring the quality and thorough coverage of exam blueprint objectives.  This one looks pretty good and based on my positive experience with Exam Cram books in the past (Active Directory Services Design), I would recommend this book.  As a certification focused text, it contains practice questions at the end of each chapter and a comprehensive 75 question practice exam at the end of the book to test your knowledge.  Elias is open in that this book is recommended as supplemental learning in addition to the VMware ICM class (required for the certification) and a few other sources such as the VMware PDF documentation, but to be honest I think he sells himself a little short.  At well over 300 pages of exam focused material, I think it will go a long way towards passing the VCP-410 written test.

The book is available at Amazon in paperback for $28.40 or the Kindle version for $25.56.  Pearson was kind enough to ship me several copies which I will make available an the upcoming Minneapolis VMware User Group meeting.

What are you still doing here?  You should be reading this book.  Go.

StarWind Partners with OnApp Cloud Hosting

February 3rd, 2011

Press Release

Burlington, Mass. – February 02, 2010StarWind Software Inc., a global leader in developing iSCSI SAN software for small and midsize companies and OnApp, a leading developer of cloud management software for hosts, have joined forces to provide OnApp’s hosting cloud customers with an affordable and highly available SAN, free for one year and for a low monthly fee after the 1st year. Storage in the cloud helps overcome the burden of purchasing an expensive SAN solution, delaying or preventing IT’s migration to the cloud.

OnApp cloud software enables hosting providers to deploy clouds on commodity hardware, and manage cloud resources, failover, users and billing through a simple point-and-click interface. Cost-efficient and reliable storage is essential for stable business continuity in the cloud. The StarWind iSCSI SAN’s architecture and rich feature set provide an ideal solution for OnApp’s hosting customers. Since StarWind software can be installed on commodity servers the price point enables cloud services to be affordable, and eliminates vendor lock in associated with proprietary SAN hardware vendors.

“There’s a huge need for cost-effective storage in the hosting mass market, and especially in the fast-growing cloud hosting market,” said Carlos Rego, MD and Chief Architect of OnApp. “With StarWind we’re making it easy for hosts to add high performance cloud storage without huge up-front investment in SANs. Our special free for the 1st year  licensing offer helps reduce entry costs to cloud hosting, and with OnApp’s monthly licensing, another vital component of cloud hosting infrastructure is moved from CAPEX to OPEX.”

The StarWind partnership allows OnApp customers to deploy High Availability storage with a free one-year license for StarWind Enterprise HA 16TB or Unlimited TB editions, for up to two servers. After the 1st year, OnApp customers can license StarWind’s HA 16TB or Unlimited TB editions for a low monthly fee.

“Cloud hosting is the future of hosting and high availability storage is critical to provide server and application redundancy and uptime. In cooperation with our partner OnApp, we are pleased to contribute to the growing the cloud space. OnApp provides cost-effective and flexible cloud platforms and StarWind Software guarantees affordable and highly available SAN storage in the cloud,” said Art Berman, CEO of StarWind Software, Inc.
