HPE Stackato 3.4.2 / 3.6.2 cloud deployment automated for vSphere – Powershell

Share This:

Build template:

In order to run the Invoke-VMscript cmdlet, we need to spin up stackato VM from ovf, install VMware tools, run some recent updates/patches and save this VM as template.

  1. Deploy stackato VM from OVF
  2. Open VM Console and configure OS:
    Login with stackato/stackato
    Reset stackato password to stackato123 using passwd
    Change IP: kato op static_ip (give it free temporary IP in 172.x.x.x) example:
  3. Restart server:
  4. Set passwordless SUDO
  5. Update Ubuntu OS (glibc)
  6. Install VMware tools & Hardware
  7. Change permission for interface settings
  8. Set the IP address to 192.168.100.100 (this will be overwritten by the script):
  9. Shutdown guest OS and upgrade virtual hardware
  10. Clone VM to template, name should be stackato-3.x.2-template-vm-tools

vBlock upgrade: Cisco Nexus 1000v VSM upgrade guide – example target version 5.2(1)SV3(1.5a)

Share This:

Cisco Nexus 1000v VSM upgrade

1.Download the necessary files from VCE portal based on your target RCM


2.Verify all the prerequisites on Cisco documentation:

(here’s the example for version we are upgrading to 5.2(1)SV3(1.5a)

3.Make sure there is sufficient space on active and standby VSM:

Log into active VSM
check active VSM disk space:
check the standby VSM disk space
– If needed delete old files using ‘delete’ command (always leave the current VSM version files just in case for the restore)
– repeat the same for standby VSM:

4.Copy the files onto active VSM.
In order to transfer the files, log onto active VSM and run:
– copy those onto the standby VSM

5.Copy running configuration to startup configuration

6.Power off standby VSM and clone to template:
After that power on the standby VSM and wait until it comes back up.

7.Backup and pre-checks
Log onto active VSM.
Copy running configuration to startup configuration:
Run pre-checks:
pre-cheksblog
Looking above we can see that the impact state is non-disruptive, we can verify the current and new version as well as ESXi compatibility.
It’s crucial that ESX hosts are compatible at this stage as the VEMs are not upgraded yet.

8.Verify Cisco VSG is not present in configuration

9.Begin the install
This will show the pre-checks table again and will prompt if you would like to take a backup. Select N (if you select Y, the installer will quiet and the backups are to be taken manually via scp commands as done in step 7)
The installer will hang on “Switching over onto standby” : (SSH session may timeout here, it’s OK!)
standbyblo
At this point wait few minutes and log-in to VSM (which is the standby VSM which has now became the active VSM)
Once logged in run:
blogcompl

10. Post-Installation checks
Run show version command on both active and standby VSM:

This should return the target version in our case 5.2(1)SV3(1.5a)

Copy running configuration to startup configuration (IMPORTANT)

Upgrade completed!
 

vSphere 6u2 permissions vs perl SDK API calls.

Share This:

Prior to upgrading to vSphere 6  (running 5.5) my user account had a read-only privileges on the vSphere object, Datacenter object, as well as some grater rights on clusters, vDS and datastore.

Using Perl SDK to deploy new VM’s – vmcreate.pl worked fine.

PowerCLI C:\Program Files (x86)\VMware\VMware vSphere CLI\Perl\apps\vm> perl .\vmcreate.pl –url https://vCenterServer.local:443/sdk/webService –filename C:\Sc
ripts\XMLVM.xml –schema C:\Scripts\Schema.xsd –username ad\test
Enter password:

Successfully deployed the VM. 

After the upgrade to vSphere 6u2 each time the script was run, it returned an error:

Moreover the VM could be easily created in that cluster / datastore etc using both Web Client and C#.

Solution:

After ripping permissions top to bottom and bottom to top it looks like for some reason it requires administrator privileges on the data center object.

I’ve tried to narrow it down and create the custom role  (focusing on Inventory and Virtual machine privileges ) however there are some further issues.

C# client and API would work, but I was unable to deploy VM manually in the web client… ?!?

Leaving this permission as administrator on data center object non-propagating looks to do the job for now.

I’ll keep this post updated if I find time to drill down into it further.
