Error (25240)

Adding a member to the adapter team Applications failed with error Unable to find Adapter HP FlexFabric 20Gb 2-port 650FLB Adapter #2 in Team after addition

Recommended Action

Ensure the team is functioning correctly and retry the operation.

I ran into the following problem applying a Logical Switch to a some shiny new hyper-v hosts , i could select the adapters and create the Logical Switch , but appyling it ended up in a rollback after it tried to add the 2nd adapter to the team

After looking around for a bit i saw that the 2nd network card was disabled in Windows

And after enbling the network card everything was green again

So always check the cable Smiley err i mean the network card

This post will cover the basics for settings up integration with Amazon Virtual Tape Library with AWS/Glacier as target

Microsoft have a competing solution that integrations Azure into the Data Protection Manager Console , that have been covered in earlier post and will be covered more in a post where the two solutions is being compared

Amazon Virtual Tape library is a low cost highly flexible solution and below if their own description of the device

Gateway-Virtual Tape Library (Gateway-VTL): With Gateway-VTL you can have a limitless collection of virtual tapes. Each virtual tape can be stored in a Virtual Tape Library backed by Amazon S3 or a Virtual Tape Shelf backed by Amazon Glacier. The Virtual Tape Library exposes an industry standard iSCSI interface which provides your backup application with on-line access to the virtual tapes. When you no longer require immediate or frequent access to data contained on a virtual tape, you can use your backup application to move it from its Virtual Tape Library to your Virtual Tape Shelf in order to further reduce your storage costs.

Pricing is difference from each region , and long term storage cost is alot cheaper than “near” online storage.

So its time to grab a excel jedi and calculate the cost vs Azure vs Tape

Amazon have a very good guide to setup a new gateway , suppport requirement for Hyper-V is right now 2008 R2 , this test is on 2012 R2 so unsupported and not usable for production until Amazon gets the VTL upgraded.

image

The gateway have 3 modes , this post will cover the Virtual Tape Library mode and not the other operations.

Supported Hypervisors and Host Requirements

You may choose to run AWS Storage Gateway either on-premises, as a virtual machine appliance, or in AWS, as an Amazon EC2 instance.

AWS Storage Gateway supports the following hosts for deployment on your premises:

VMware ESXi Hypervisor (version 4.1 or 5.0). A free version of VMware is available on the VMware website. You will also need a VMware vSphere client to connect to the host.

Microsoft Hyper-V 2008 R2. A free, standalone version of Hyper-V is available at the Microsoft Download Center. You will need a Microsoft Hyper-V Manager on a Windows client computer to connect to the host.

Supported Backup Software (Gateway-VTL Only)

Typically, you will use a backup application to read, write, and manage tapes with a gateway-VTL.

The following lists the third-party backup software that Gateway-VTL supports.

Microsoft System Center 2012 R2 Data Protection Manager

image

I want to run the AWS Storage Gateway on Microsoft Hyper-V

image

Download the AWS Storage Gateway Virtual Machine (VM) software. Unzip the downloaded file and make note of the location of the folder that was created.

image

Using Microsoft Hyper-V Manager client, connect to the host hypervisor that you will be using to run the AWS Storage Gateway.

image

Since we cant use the template out of the box we create a new machine

image

Select name and location

image

and Generation 1

image

for testing purpose i set the vm to 8gb of memory and 4 cpu’s

image

And added a nic , this test uses one nic both for iscsi to the VTL and to transfer to the internet this can be seperated

image

Use the VHD supplied from the image from Amazon

image

Your gateway prepares and buffers your application data for upload to AWS by temporarily storing this data on disks referred to as upload buffer.

Using your Hyper-V Manager client, allocate one or more local disks to your gateway VM for your gateway’s upload buffer. To estimate the amount of upload buffer your gateway requires, use the approximate data you plan to virtual tape cartridges on a daily basis. It is strongly recommended that you allocate at least 150 GBs of upload buffer. You can refer to our documentation for a more precise calculation.

image

for testing i added a small workload so we didnt need large cache files locally

image

image

image

image

So 2 files og 256GB was added to the VM

image

time to power on the VM

image

hit 2 Static Ip Address

image

image

add the ip address on the gateway activation

image

Select the Medium Changer STK-L700 for Data Protection Manager Support

image

Its time to create some virtual tapes

image

First step is to setup the Upload and Cache on the 2 drives created on the VM

image

image

100GB tapes with a prefix for TEST

image

And we now have a virtual tape libray and LTO drives

image

On the DPM server connect through ISCSI to the VTL VM

image

image

Connect the 10 drives and the media changer

image

In device manager update the unknow media changer to Sonly A500C

http://docs.aws.amazon.com/storagegateway/latest/userguide/backup-DPM.html

image

image

in DPM hit Rescan under Library

image

You will see the Libray and 10 stand alone drives

image

Hit “Add Tape” to impor the virtual tapes

image

image

net stop DPMLA

The DPMLA service is stopping..
The DPMLA service was stopped successfully.

STOP the loader service

C:\Program Files\Microsoft System Center 2012 R2\DPM\DPM\bin>DPMDriveMappingTool

.exe
Performing Device Inventory …
Mapping Drives to Library …
Adding Standalone Drives …
Writing the Map File …
Drive Mapping Completed Successfully.

Run the DPMDriveMappingTool

C:\Program Files\Microsoft System Center 2012 R2\DPM\DPM\bin>net start dpmla

Start the Loader service

The DPMLA service was started successfully.

C:\Program Files\Microsoft System Center 2012 R2\DPM\DPM\bin>

image

Rescan the library again

image

And you should see a loader with 1600 slos and 10 drives

image

Run a detailed inventory, note since its 1600 slots its takes 10-15 minutes on my test machine

image

And we now have something to backup to

image

Modify the protection group to add Long Term Storage

image

Select a fitting schedule

image

For testing i only uses one drive and compression not encryption , security will be convered in a future post

image

Create Recovery Point

image

And select long term recovery

image

and we know have backup to cloud instead of local tape drive.

Next post will cover more detailed monitoring of cache/buffer and tape handling in Amazon


Integrating HP 3PAR Into Virtual Machine Manager 2012 R2

Comments Off on Integrating HP 3PAR Into Virtual Machine Manager 2012 R2

HP have 2 integrations with Virtual Machine Manager , this post will cover the basic install of the HP Storage UI Add-In for System Center , this tool provides a overview of the storage connected to the Microsoft Hyper-V / Microsoft Virtual Machine Manager Installation , 2nd a post will cover SMI-S integration for assigning storage to Hyper-V hosts

 

This post will cover the install and a few screen shots of the UI integration with Virtual Machine Manager

 

 

image

Start the installer

image 

This is the install on the Virtual Machine Manager server so we will select HP Storage UI Add-In Server

image

Select path for install

image

Go Go

image

Install should not take more than a few minutes

image

DO NOT use a domain admin for this purpose , testing with the Hyper-V management account , not sure why HP wants to use a domain admin seems like a terrible idea

image

So i will use the Hyper-V account used in VMM again needs further testing

image

Go to Settings Console Add-Ins , ensure that you did a run as administrator when launching the VMM console

image

Import the add-in

image

Go Go

 

image

Add the HP 3PAR storage systems through VMM

image

Set the IP address on the 3PAR’s and select the action account

 

image

 

image

Just for testing i added the FC and NL for provisioning in a later post

image

Go Go

image

In the VMM console select HP Storage Management , and select Authorize on the storage systems , this will prompt for credentials

image

And we now can see what LUN on the 3PAR a VM is located on and what paths/speed is used

image

And a general overview of the 3PAR

Do not stop , go to your test enviroment patch hyper-v and DPM and Enjoy

So one of the news in UR3 to Data Protection Manager 2012 R2 is the Scalable VM Backup

This adds more scale to each DPM server ensuring backup of the VM on each host

http://support.microsoft.com/kb/2966014

Features that are implemented in this update rollup
  • Scalable VM backup
    This update rollup improves the reliability at scale for Virtual Machine (VM) backups on Hyper-V and Windows Server 2012 R2 infrastructures. This feature is supported on both Cluster Shared Volumes (CSV) and scale-out file server (SOFS) storage configurations for VMs.
    Prerequisites

 

Ensure April Update on Everything

image

So patch your test dpm servers and update the agents

image

Reboot is NEEDED even on 2012 R”

image

Sucess Smiley

 

image

You will need to run a consistency check of all VM’s

image

image

DPM issues a checkpoing before the CC

image

After checkpoint is complete we can create a recovery point

image

image

And we can see the snapshot being created and the deltas moved.

image

and on the plus side , no more errors on the VDS Basic Provider after the upgrade , and from the testing so far no issues with ODX enabled

PATCH TEST WAIT DEPLOY in PRODUCTION

Backup with ODX enabled on HP 3PAR with Data Protection Manager

Categories: 3PAR, Data Protection Manager, DPM, Hyper-V, Windows Server 2012 R2
Comments Off on Backup with ODX enabled on HP 3PAR with Data Protection Manager

 

So far we had a mixed experience with ODX and HP 3PAR  , backup was painfull with locked luns , moving vm around was even more painfull with data corruption

So until now we have disabled ODX on everything 3PAR related other arrays have issue with backup , and since its software the solution so far have been a mix between HP and Microsoft

This is “only” a issue when doing backup of a CSV volume standalone host havent been affected again back to the mix between HP and Microsoft

From what we seen so far

 

 

2012 R2 with April update and http://support.microsoft.com/kb/2966407 will fix

Assume that you install update 2919355 on a Windows 8.1-based or Windows Server 2012 R2-based computer. When you try to back up some Hyper-V virtual machines that reside on cluster shared volumes, you receive an error message that indicates the backup request has failed.
Here is a sample of the error messages that you may encounter when this issue occurs:

Error(s): vss_e_unexpected_provider_error
Csv writer is in failed state with unexpected error

 

On the 3PAR side we have upgraded to 3.1.3 and will apply some more patches tomorrow and continue testing

SCOPE

Windows Server 2012 or Windows Server 2012 R2 hosts with ODX in use with HP 3PAR StoreServ Storage running HP 3PAR OS version 3.1.2 GA, 3.1.2 MU1, 3.1.2 MU2, 3.1.2 EMU2, or 3.1.2 MU3.

RESOLUTION

Upgrade the HP 3PAR OS on the HP 3PAR StoreServ Storage to 3.1.2 MU2 or later if running a lower HP 3PAR OS version. Next apply the patch as follows:

  • For 3.1.2 MU2 and 3.1.2 EMU2, apply Patch 11 followed by Patch 36.

  • For 3.1.2 MU3, apply Patch 30.

 

image

So after Windows Patches and Upgraded 3PAR we can now backup mutiple VM (was 2 before) and move data around with ODX enabled.

What remains for the next week is to move VM around with storage migration to verify that the data corruptions also is history.
