Datastore missing – but Disk / Array detected?

I recently was playing around with ESXi and Removed my drives via the motherboard connections, tried another drive type and then tried to reconnect my orginal drive configuration. ( a non supported ICH9 controller, and Sata Drive )

I had no problem with the disk being detected upon a new rescan of LUN’s, but my data store did not show up.

Dave.Mishchenko pointed to page 117-118 of the ESX / ESXi iSCSI San Guide


VMFS Volume Resignaturing
ESX servers need to be able to differentiate between their VMFS volumes and use a
volume signature to do so. When a VMFS volume is replicated or a snapshot is taken,
the resulting LUN copy has the same signature as the source. When an ESX Server sees
two LUNs with the same signature, the ESX Server must handle the condition to
prevent downtime caused by confusion over which LUN it should be using to access
the registered virtual machines. Resignaturing is a feature introduced in ESX Server 3.0
to solve this problem.
Mounting Original, Snapshot, or Replica VMFS Volumes
You can mount original, snapshot, or replica VMFS volumes on the same ESX Server
host.
To mount original, snapshot, or replica VMFS volumes
1 Perform the required storage tasks:
a Make the storage system snapshot or replica.
b Configure access control to allow ESX Server to access the snapshot or replica.
2 In the VI Client, select the host in the inventory panel.
3 Click the Configuration tab and click Advanced Settings.
4 Select LVM in the left panel, then set the LVM.EnableResignature option to 1.
5 Rescan for any new LUNs or VMFS volumes.
After the rescan, the copied VMFS volume appears as
/vmfs/volumes/snap-.
If the VMX file for any of the virtual machines or the VMSD file for virtual machine
snapshots contains /vmfs/volumes/

This seemed to work great!

Thanks to Dave

Update : VMware VMotion ESX server support for Symantec AntiVirus and Symantec Endpoint Protection

Update : VMware VMotion ESX server support for Symantec AntiVirus and Symantec Endpoint Protection

Symantec has posted a updated KB Document ID: 2008101607465248 on VMware VMotion ESX Server Support


Question/Issue:
Is VMware VMotion ESX server supported with Symantec AntiVirus and Symantec Endpoint Protection?

Symptoms:
Symantec supports running Symantec AntiVirus, Symantec Endpoint Protection, and Symantec Endpoint Protection Manager in VMware environments.

A few customers have reported problems with Symantec Endpoint Protection Manager with VMware VMotion ESX server. These problems may or may not be related to the presence of VMware VMotion or the presence of the Symantec Endpoint Protection Manager.

Some the problems include:

* Client communication problems
* Symantec Endpoint Protection Manager communication problems
* Content update failures
* Policy update failures
* Client data does not appear in the database
* Replication failures

Solution:
Symantec is investigating each support case and will update Symantec products where necessary. If you experience a problem that you suspect is related to VMware VMotion, please contact Symantec Technical Support.

I am glad they have put out a KB addressing this, and i hope in the future, they realize the impact such statements have in the industry.

Thanks to Yellow Bricks on posting this 1st.

Running VMware ESX 3.5 and ESXi in Workstation on your desktop PC

Petri IT Knowledgebase has a interesting post on Running VMware ESX 3.5 and ESXi in Workstation on your desktop PC


In the following new video, I demonstrate, step by step, how you can run VMware ESX Server 3.5 and ESXi 3.5 inside VMware Workstation 6.5. This is also shown in my Train Signal VMware ESX Server video training course.

While you wouldn’t run ESX in Workstation for a production server, running ESX in Workstation is an excellent way to test and demonstrate ESX Server (and the entire VMware Virtual Infrastructure suite) on a single PC. Think about it – what if you had a single PC with 2 ESX Servers, an iSCSI virtual SAN, and a Windows Server running Virtual Center. With that, you would have “VMware Infrastructure in a box” and be able to run powerful features like VMotion, SVMotion, VMHA, and Update Manager, all on a single PC.

I am running a HP DC7800P workstation, with ESXi via a USB stick, ( for testing ) and I this is a different take, and takes testing to a new level.

Please post your comments!

Symantec declares VMware VMotion unsupported

Symantec declares VMware VMotion unsupported by Jason at Boche.net

Bad news for VMware VI Enterprise customers everywhere. I just found out I have 110 unsupported production and development VMs in my datacenter. Symantec published Document ID 2008101607465248 on 10/15/08 removing VMware VMotion support from its Symantec Antivirus (SAV) and Symantec Endpoint Protection (SEP) products.

Operating systems impacted are: All Windows operating systems.

Reported issues include but are not limited to:

* Client communication problems
* Symantec Endpoint Protection Manager (SEPM) communication issues
* Content update failures
* Policy update failures
* Client data does not get entered into the database
* Replication failures

Bad news indeed, I hope that that Symantec up’s their game and gets this working.
