vmware, virtualization

Can you please let me know what tools or means or how to check below.

Check the health of all Hosts and VM objects in vCenter. Are there any active alarms in vCenter?

Are all vCenter plug-ins functioning properly?

If any Host Hardware issues? Alarms, bad memory, power supply or capacity issues?

if any resource bottlenecks? Memory, CPU, Disk, Network?
is the load properly distributed?
if running out of resources anywhere? LUNs with low disk space, etc.
Check for Firmware updates on Host hardware- can we use update manager

Check for ESX Patches
Check for VM Patches
Check VMware Tools version
Run scripts to identify the existence of VMs with snapshots and follow up to see if they are still needed.
Have you schmoozed with your Storage Admins lately? A good idea since you cannot get very far without them.

Clone a VM

I have an AD joined the server with applications. I want to build another identical server.
What is the best way to do this? The new server will be joining to the domain with a new name and SID. I would appreciate it if you could help me with this.

Ran job but it failed with the same error.

Ran vssadmin list writers - the VSS NTDS was in error.

Need .NET Framework VDI / VM Preconfigured

Are there VDI's where Visual Studio / SQL Server / Source Code Management

come pre-installed? That would save me some potential aggravation...

Thanks

I am trying to create a Windows 10 Pro VM on a 2019 Std server. The ISO I am using is from the VLSC (SW_DVD9_Win_Pro_10_1903.1_64BIT_English_Pro_Ent_EDU_N_MLF_X22-14064) I do not want to use 1909 due to search issues. I have the VM setup so that the OS installs on startup. The error message I get is "Windows could not complete the installation. To install Windows on this computer, restart the installation"

I have deleted and recreated the VM, downloaded a new ISO and both receive the same message.

Hi, we are looking at some further guidance on setting up failover clustering on two Windows Servers 2019 connecting to a HP MSA2052 SAN.

•      The servers are DL380 Gen10 with 8 NIC ports.
•      The current wiring connections are shown below (we will redo this for redundancy on the controllers)
•      The MSA 2052 has two controllers, each controller has two connections on different subnets connecting to the two servers via one switch with two vlans. (Layer 2 switch)
•      The servers connect to a different production switch for normal data traffic.
•      The iScsi initiators and MPIO have been configured and both servers can see the storage volumes.
•      The Servers can both ping all four ip addresses on the 172.16.*.* subnets, the nics on the 172.16.*.* subnets, don’t have a default gateway configured as per guides we have been reading. Jumbo frames are set up on the iSCSI NICS and switch.
•      The servers are pingable via their full domain name from other devices on the 10.226.*.* production network. The servers are in the correct Server OU.
•      The servers currently don’t have a network setup for a heartbeat and migration.
•      The servers also have Teamed NICs setup for a virtual switch within HyperV manager

The failover clustering invalidate configuration wizard test is failing on:
At least two independent paths to storage target are recommended for each Test Disk
Test Disk 0 from node Server1 (shows FQDN) has 1 usable path to storage target
Test Disk 0 from node Server2 (shows FQDN)…

Hi,

I can no longer access my VMware vcenter inventory. When I log into the web client, I see this message:

Could not connect to one or more vCenter Server systems:
https://server name:443/sdk

If I try to connect using the vSphere client I get the attached message.

I can login to the Microsoft Server with the vcenter server, and I can SSH to alle the ESXi servers but not the vSphere server.

I'm running an older VMware version 5.1.0 Build 1115182.

How can I fix this?

Thanks,
Ronnie

Please suggest a Virtual Desktop Infrastructure (VDI) Platform

Please suggest a few good brands I should consider...

I expect to use Windows 10 and the .NET Framework set of Dev Tools.

I need a VDI for some development work and expect to also have some offshore developers also help. I presume one VDI per developer.

Make any sense? (This only MAY work with free Open Source software)

Anyway, I need some good branding VDI options. Free is better, but key features may make a small fee worth it.

Thanks

I have just had a product update go very very bad on a VM.

I am restoring from the backup from before started doing anything right now.

The VM had two drives C and D.

D is just a data drive.

My question is. Will I be able to use the .VHD file for the secondary drive? Or will I need to restore from a backup also.

I mean it depends what the upgrade did however I don't think the data on this drive was changed.

Points of My Scenario
1. I am admin for our VMware infrastructure: vCenter Server 5.5 on ESXi 5.5 cluster
2. Microsoft has asked me to update the BIOS for one of the Windows VMs - not the ESXi host
3. I upgraded the hardware version of the VM (from version 8 to version 9)
4. This hardware version upgrade did not change the BIOS version of the VM (Note: I used Windows' built-in msinfo32 to get BIOS version).
5. Info: The VM's "BIOS version/Date" - as reported by msinfo32.exe - is "Phoenix Technologies LTD 6.00 9/17/2015"

QUESTION: How do I upgrade the BIOS of a Windows VM (Server 2012 R2) hosted by an ESXi 5.5 server?

Hello All;
(Windows 2016 Server running SQL Server 2019 Cluster installation)

I have run into an issue and I am at a complete loss as to what to do about it.
The only other option is to delete the VM and create a new one and re-do the process and see if it will work then.

OK.
On a Virtual Machine.
I have SQL Server 2019 installed as a cluster.
Currently, there is only ONE server running in this test run.

Connecting to the server through SSMS 18.4
From my laptop to the server, it fails every time. Error 26
I have done the following.

(On the VM Server)
Made sure all SQL items in the Services, are in fact running and they are from the get-go.
Open Firewall for programs: SQLBrowser and SQLServer. (Also for good measure, I created two more rules for 1433 and 1434)
For SQL Server Config Manager - Enabled all items, TCP/IP, set on port 1433 for both the IP Addresses shown.
(Actually, there are IP Addresses in the TCP/IP config, that I have NO idea what the heck they are, or how they got in there???)

I checked the DC for entries in DNS, and all IP addresses are entered.
Both for the two NICs and the Cluster assigned IP.

Installed SSMS 18.4 on the VM Server, and it connected to it, without an issue.
I also checked once I launched SSMS to make sure it was set up to allow connections, and it was by default.
It just will not connect through the network.
Now, this is NOT my first time working with a VM Machine with SQL Server and connecting with …

Hi there,

We set up a VM with Windows 10 (build 18363) and for a couple of days it was working just fine and we could RDP to it. Now whenever we try to RDP to it, we get instantly disconnected and we get an error that says "Because of a protocol error, this session will be disconnected. Please try connecting to the remote computer again.". We've restarted the VM and also checked all of the usual RDP settings (firewall, NLA, Users) and they all seem OK. We even restarted the RDP service, but we cannot connect. Any help would be greatly appreciated as we want to build a lot of VMs with this new Windows 10 version.

Thanks,
- Christian

Modifying Roles / Privs

In vSphere 6.7, which role would i need to disable so a user cannot modify VM settings such as
(Upping RAM, adding CPU's, adding Devices)?

Can it even get granular
can a role be modified so a user can add a USB drive, but not add more RAM, etc

On Server 2019 Azure VM (RDS Role): I restored the machine from an Azure backup successfully.

Everything seems fine except that every time someone logs on (admin or user) the Shutdown Event Tracker pops up asking what happened. It doesn't matter if the question is answered or not--it keeps coming up.

How can I get rid of it?

I am proposing a major upgrade for one of my clients.

Up till now, we have been using a 3rd party registrar for business emails. Lately my client continues to ask for additional emails accounts to be setup - exceeding our purchased quota. I have also been pressed for synchronization on inboxes with iphones. For the time I have been configuring via IMAP. Needless to say, they have out grown this basic email package.

Yes I have considered Office 365 Business, and Premium w/ Exchange, but, I want to investigate my options in-house. I can't seem to get past that reoccurring annual charge.

We currently have a 1 Dell PE R320 running Windows Server 2012 R2 Standard. There are 13 users in the office environment, 10 out in the field. We have a 3rd party business application running off of SQL on this same server. Our system comes with the ability to created 2 VM'S, running the Server 2012 R2 Standard. I'm thinking great, I don't have to spend another 2,500 on a server, I'll use what I already have. Then I read the following on Microsoft:

• Only management software (for example, antivirus software, backup software, or virtual machine management software) can be deployed on the physical host machine. No other server-based applications (for example, Exchange, SQL Server, Active Directory, or SAP) should be installed on the host machine. The host machine should be dedicated to running guest virtual machines.

So, that is the warning. Has anybody actually tried to do this, …

Hi,

I have a VM in vmware that is being used as a file server. The files are residing in a LUN that is shared directly with the VM through iSCSI. (It appears as a second drive in windows.)

I want to upgrade the file server and I figure the easiest way to get this done is put up a new VM on the same Host and make another direct iSCSI connection from the VM to the ISCSI target (the same LUN). This way I will have all company files instantly without having to use any backup/restore software and save on SAN space.

Does this make sense? If it does,then what will happen to all my ntfs/sharing permissions that were configured on the old file server. Will they be transfered also since the LUN was moved?

Thank you.

Exchange 2013 mailbox issue

Exchange 2013 mailbox issue

Hi friends.
I would like to ask someone with Exchange expertise for advice

Last time my Veritas backup exec screwed my Exchange server. In process of backup for over 2 weeks start created new maiilbox snapshot so after 2 weeks I've got 10 VM snapshots.
This caused my incremental backup to take 19 hours to complete.

I've decide to delete snapshot from VM console but somethings went wrong and after restart one of my databases reported error.
I've restored database from backup so all works good now. Never mind, but I've notices strange situation on one of my mailbox.

I have user with unlimited quota and Exchange is showing his mailbox size over 31 GB, but when I've checked his Outlook 2016 folder, the size of OST file is only 4GB and settings for his outlook is to use cache mode so I don;t understand why information store is showing 7x more taken space.

Hyper-V problems...

Trying to set up Hyper-V on a Windows 10 Pro laptop.
When trying to open the Hyper-V manager, I get a message saying
The Virtual Machine Management Service (VMMS) is not running on this machine.
That is not listed in Services, either, but under add windows features, Hyper-V shows as being installed.
