Howto Reboot/Shutdown Windows Server 8

I can't believe I am actually writing this...with all the major changes Win8/Win8 Server are bringing one would never think they would change how you shutdown or restart, right?  Well we are wrong...

You can't just click Start->Shutdown anymore, old schoolers might remember this one:

Alt+F4

Focus needs to be on the desktop (minimize all other windows, or click on the wallpaper so focus is on the desktop) then hit Alt+F4 to see a familiar window:

Windows Key+C

This is the "Charms" shortcut key.  Charms is a Microsoft term for these icons that appear when you hit Windows Key+C:

Then Click Settings:

Now you can click Power & select Restart or Shutdown.

Howto Install VIB Patches on ESXi Hosts Without Update Manager

So you find yourself in a position where you need to update one (or more) of your hosts but don't have vCenter Update Manager around to assist.  In my case trying to get Windows Server 8 CP working....It's not terribly difficult, you simply:

  1. Download the patch - you can download patches direct from VMware @ the Patch Portal
  2. Open a datastore with enough freespace to store the patch via your vSphere Client (Right-Click->Browse on a datastore)
  3. Upload the patch you downloaded (should be a .zip file)
  4. SSH into the host
  5. Execute the command "esxcli software vib install /vmfs/volumes/<DATASTORE-NAME>/<PATCH-NAME>.zip"  - replacing the <DATASTORE-NAME> and <PATCH-NAME> appropriately.

This command can take some time to execute for large patches.

When it's done you should get some text like below, remember to pay attention to this text so you know if you need to reboot your host or not.

Dell Management Center Plugin for vCenter Overview/Install Guide

Dell introduced this plugin awhile back, it's actually a Virtual Appliance you import into vCenter.  The plugin inside vCenter is actually an Adobe Flex (Flash-based) app that gets embedded into your vSphere Client, so ensure you have Flash installed on the machine(s) you wish to use this plugin from.

Overview of Features

  • Update BIOS/Firmware on Dell ESXi hosts from vCenter
  • Checks for updates automatically and alerts you when there are updates available
  • Can leverage an established Dell Repository to avoid data duplication--if you are a heavy Dell shop you should know what this is
  • New vCenter Alarms for Dell Hardware
    • These Alarms can even trigger hosts to go into maintence mode to evacuate VMs from that particular host if the hardware event is critical (in a DRS enabled cluster of course)
  • Supports Dell's Proactive Systems Management
    • Works without (the God-awful) SilverStreak to automatically create support cases with Dell when issues arise
  • View Warranty information of your Dell hosts
    • Allows you to configure a proxy, if your environment requires one
  • Bare metal deployment of ESX/ESXi servers
    • This leverages Dell Lifecycle Controllers and iDRACs to provision Dell servers somewhat auto-magically.
    • First you create a Hardware Profile from a Reference Server--(configures boot order, BIOS settings, iDRAC settings, RAID config)
    • Then you create a Hypervisor profile--You point at an ISO, and configure the vCenter, destination container (data center or cluster), and even a host profile for you enterprise plus users.
    • Note you can "white-list" service tags so only those hosts you define can be used by the plugin to deploy against.
  • OSMA Launcher
    • So you can launch directly to your OSMA web console to connect to an OSMA agent on an ESXi host
  • Appliance Upgradable
    • Does not require replacement by deploying a new OVF when a new version comes out

    WhatsUp: Dell Server Hardware Status Monitor

    WhatsUp v14 added some nice new active monitors to monitor fans, power supply and temperature for Dell Servers.  However that doesn’t cover everything else, Memory, CPU, Chassis Intrusion, HDD, RAID Controllers, etc.  We found the simplest way was to simply monitor for the LCD color of the Dell server.  Yes, we are sure the OID that we are looking at isn’t actually LCD color, but we like to think that it is.  The OID is actually for drsGlobalSystemStatus--which if it's not 3, then there is a problem and the LCD is amber to reflect that.  Below is how you can setup this active monitor for WhatsUp:

    First you need to configure SNMP on your DRAC, this screenshot shows the steps:

    Once you have SNMP configured on your DRAC you can setup the SNMP Active monitor in WhatsUp as follows:

    vCenter Orchestrator Trouble: Server service fails to start – service terminated with service-specific error Incorrect function

    I was setting up a new instance of Orchestrator inside my lab and came across this issue.  the Orchestrator Server service would not start, andi nside the vCenter Orchestrator Configuration webpage, we don't have any output in the log--so we investigate the Windows logs...

    In the system log all you see is Error: The VMware vCenter Orchestrator Server service terminated with service-specific error Incorrect function..

    Poking around we come across a log file @ C:\Program Files\VMware\Infrastructure\Orchestrator\app-server\bin\wrapper.log which sheds some light on the problem:

    Your first thought might be disk space, did a log run away? No that isn't the case--Java Heap refers to memory, looking inside the wrapper.conf from the command above we find more information.

    Java has to allocate 2Gb of RAM on startup. My VM only had 1.5Gb, that looks like the issue--this is what you get for ignoring the Minimum System Requirements (assuming your running Orchestrator on same server as your vCenter).  Increase the RAM on your VM and this error should be gone. vCenter Server should have a minimum of 3Gb of RAM.

    Orchestrator Workflow: Change vCPU Count

    I guess the guys behind vCO missed including this workflow in the default install--(hey they had to miss one after making so many hundreds--right?)

    Simple little workflow, thought I'd post it up to save anyone the trouble of recreating...

    1. Start Service
    2. Navigate to IP:8282
    3. Login with user vmware password vmware
    4. Select Network on the left
      1. Select IP address to bind to
      2. Confirm rest of settings on page (adjust ports if any conflict with other software on the orchestrator host)

      4. Network should now have a green bubble next to it, proceed
    5. Select LDAP on the left
      1. Select Active Directory from the dropdown if it's not already selected
      2. Enter your primary & secondary LDAP hosts (domain controllers) note: secondary is optional
      3. Enter your LDAP root path, if your domain is requeny.lan enter: dc=requeny,dc=lan
      4. For username enter user@domain ex: vco-service@requeny.lan
      5. Password- this should be obvious
      6. Enter your User lookup base path: (where all your users are located, ex: cn=Users,dc=requeny,dc=lan (this would point to the Users OU in active directory)
      7. Enter your Group lookup base path: (where all your groups are located, ex: cn=Users,dc=requeny,dc=lan (this would point to the Users OU in active directory)
      8. Enter the path to your vCO Admins Group, ex: cn=vCOAdmins,cn=Users,dc=requeny,dc=lan
      9. Hit apply changes, if all your settings are correct LDAP should now have a green bubble next to it, but before continuing click the Test Login tab at the top and attempt to login with a user in the vCOAdmins group

      7. Instance name: whatever your instance name is, ex: sqlexpress
      8. Domain: your AD domain here, use the NetBIOS name here, ex: requeny
      9. Hit apply changes, if all your settings are correct you will get an error under Validation results that says: Database connection successful.  No schema found.  Please initialize database.  What this means is your connection worked, however there are no tables in the database.
      10. At the top you should see a new link Install the database, click that (this should only take a couple of seconds)
      11. You should now have a green bubble next to Database, proceed on
    7. Select Server Certificate
      1. If you don't have a certificate CA, select Create certificate database and self-signed server certificate

    8. Select Licenses
      1. You can either enter a vCenter Server license manually, or Orchestrator can connect to your vCenter Server and read the license on it's own.
      2. To connect to a vCenter Server and read the license:
        1. Check the use vCenter Server license radio button
        2. Enter the hostname of your vCenter Server
        3. Enter the port of your vCenter Server Web Services (443 by default)
        4. Path: leave default
        5. Enter username & password of an account that can read license data from vcenter
        6. Click submit
        7. If you receive an error about 'SSL certificate is missing for this host read my other post on fixing this SSL error
        8. Licenses should now have a green bubble next to it, proceed
      3. To manually enter a vCenter Server license
        1. Check the Add vCenter Server license manually radio button
        2. Enter your vCenter Server serial number (remember you must enter a standard edition serial, foundation doesn't include Orchestrator)

    vCenter Orchestrator Trouble: SSL exception, ‘SSL certificate is missing for this host’

    Here you are trying to setup vCenter Orchestrator and you get this error: SSL exception, 'SSL certificate is missing for this host'

    What vCenter Orchestrator is saying is that it doesn't have the certificate installed for that host, unlike other apps/programs, Orchestrator doesn't offer an option automatically install these certificates upon inital connection.  You have to first add the certs then connect to the host, to do this: (refer the screenshot at the bottom if your stuck)

    1. Login to your vCenter Orchestrator Configuration Webpage: (http://vCenter-Orchestrator-Hostname:8282) - default user/pass is vmware/vmware
    2. Select Network from the left column
    3. At the top you'll see a tab for SSL Certificate, click that
    4. You can either import the SSL certificate from a file, or from a URL--URL is the easiest as you just enter the hostname and Orchestrator installs the certificate
    5. In the URL box, just enter your vCenter hostname, then click Import to the right of that text box
    6. You'll see the certificate details displayed if everything looks alright click Import at the bottom
    7. Repeat this process for each vCenter you plan to use Orchestrator with
    8. Go back to whatever step you were trying to do when you got the error: SSL exception, 'SSL certificate is missing for this host' and try it again, this time it should work successfully

    Building a Cost-Effective vSphere ESXi 5.0 Home Lab: Part 2

    So it's been awhile since my last post on Building a Cost-Effective vSphere ESXi 5.0 Home Lab--I have been playing with this system now for a few weeks and am loving it--I've ordered parts for a 2nd system and might spring for a 3rd...Remember that the chip on this motherboard supports AMD-V, so you can do practicably everything except for VMDirectPath I/O with this system.

    I've been running upwards of 7 VMs on it at once and have had no real problems.  Yes ready times can get high, but I've never had them over 30% under that kind of load.  Again this is a home lab, and somewhat high ready times don't effect anything except a couple extra seconds here or there when I am doing something intensive.

    This little box rocks for a home lab, the key thing to remember is that it IS a home lab--run everything with 1vCPU and minimal amounts of ram assigned.  (I don't have a single VM over 1Gb of RAM assigned).  The biggest slow down in my experience with this system comes from swapping on local storage--not CPU contention.  (I haven't connected this to my OpenFiler box yet)
