While doing storefront deployment we came across the error " The Citrix Credential Wallet service is not running"
It also had following error in the event log which point to some kind of timeout while starting the service.
We tried putting service into delay start mode to see if that fix the issue
While doing research we found that config file need to be modified if StoreFront server do not have Internet connectivity
And change the value from true to false and finally service got started
There might be multiple ways to allocate lun to Hyper-V clusters but I follow below way . Once lun is allocated via storage system it will be available via disk management on one of the cluster node. Bring it online and format it without drive letter and partition name.
Once drive is formatted open cluster manager and browse to storage right click to add the storage
Once added it will show up as available storage
Now we need to allocate this to cluster shared volumes
Once this is allocated it will showup under cluster manager and under SCVMM
While running cluster validation it keep throwing warning 
Warning message says that "No Disks were found on which to perform cluster validation tests. To correct this,review that following possible causes:
Here it clearly says that disk should be offline when running this cluster validation test. After bring quorum disk offline and run the validation test and it went through.
While creating virtual networking on one of the Hyper-V 2008R2 host
It was giving an error 12700 VMM cannot complete the host operation on <servername> server because of the error
I tried rebooting/removing and reading back to cluster . But then it always throw an error while creating Virtual Network. Because of this I was not even able to create VM on the cluster . It was giving error "Error 20400 1 parallel subtasks failed during execution.
Found MS KB 2486812 which explain how to fix and what is the root cause. Downloaded nvspbind and run it on problematic Hyper-V cluster.
And finally I was able to create Virtual Network
I wanted to provide CNAME as a DB connection for SCVMM rather than actual server name. The reason for doing so was to make sure incase of mirrored DB goes down, I can make DNS changes and that can take care of SCVMM rather than making registry or application level changes.There are many ways to do so but one registry hack can also make changes.
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft System Center Virtual Machine Manager Server\Settings\Sql " and update following changes
Restart System Center service and this will update SCVMM as well.
When I was trying to add node into existing cluster it throws the error message "The computer is joined to a cluster." I also found that cluster service was not started.
Hence I decided to remove feature failover cluster but then it throws the message "This server is an active node in a failover cluster. Though this node were not visible under fail over cluster
This seems to issue with stale connections . In order to clear this run PS command clear-clusternode
And finally it will allow to remove failover clustering feature.
While performing configuration of Citrix XenDesktop we found that there were no storage resource available to assign for virtual machine manager. Here we are trying to integrate System Center Virtual Machine Manager 2012 with XenDesktop 5.6
So there are few pre-requisite for storage to showup and this need to configured via SCVMM and Hyper-V host. Here we need to insure that for EVERY host placement is defined as show below
And for same path which is under placement sharing is enabled
Once this done you can view storage under virtual machine storage.

While configuring quorum for Hyper-V fail over cluster
It gave message that "No quorum witness has been configured for the cluster"
This was because quorum disk which was presented were not formatted . So formatted and assigned the drive letter Q
As soon it was added under cluster manager -> storage, it was available
Now when I ran cluster configuration again it shown up under storage
Finally this configuration will finish
I came across situation where VM created via non SCVMM had HA grayed out (Currently below screenshot is for reference)
While doing migration it was throwing error 23001 - cannot create or update a non highly available storage.
To fix this perform the migration again using following box "Make this VM highly available"
After migration this will become highly available.
This is the first time when I have created virtual machine using SCVMM. While creating VM it throws error
This seems like you can not use cluster resource till you define the resource as highly available. After checking option "Make this virtual machine highly available" VM creation went through.
I have discussed here how VLAN is created on HP virtual connect and then mapped to Hyper-V host. Once VLAN is created on virtual connect we need to use HP Network Configuration Utility to map this VLAN
Every VLAN which is created also create physical interface . Make sure you name it for better identification
Post this now we have to create logical interface on Microsoft VMM machine. Select Fabric and then create a network site.
Now select each host and then choose virtual networks. Click on Add then choose network binding as "External" . Point this to the interface created on Hyper-V host
Now under hardware choose the interface and map it to logical interface
Previous lesson 7 we discussed about setting SQL mirroring but then I was not aware what I need to do to start with SQL mirroring. I decided to blog SQL 2008R2 install steps. Remember I am doing this production for the first time in life :) So pop-in SQL 2008R2 CD/ISO and run the installer.
This will check all the prerequisite
Next it will ask what feature we are trying to install. We are installing just SQL server .
We need to insure that we have choose "Integration Service" here
This will check for all the dependencies for feature selected.
Go with default instance.
Now disk space will be calculated for above feature installation.
Configure all the service to run with service account.
Choose the correct authentication method which you want. Recommended is to use mixed mode.
If you wana to place data and log files on separate drives. Everytime when you create new database this will place MDF file and LDF file on respective drive.
One more check before installation begun.
Finally nice summary for what install is going to be done.
If install is successful it will present message with green.
