There's an updated cloud in town Part 2: Still Installing ICO 2.5

A few more hurdles overcome as I get closer to getting ICO 2.5 installed.

Some RHEL 7 notes

The firewall in RHEL7 (and 7.1) is not iptables. Instead, it's the firewalld service that's controlled by systemd. I'm not sure which install option causes it to be configured because it wasn't running on all of my RHEL 7.1 systems. Anyway, to turn it off, you can run:

systemctl stop firewalld
systemctl disable firewalld

In my case, it was blocking port 53 (dns), which I needed open to configure the vCenter server (next section). I first just used Applications->Sundry->Firewall to open port 53, then realized that I could just turn it completely off in my test environment so I don't hit any more problems with it.

Installing vSphere 6.0 Without a Windows Machine

I decided to also install vSphere 6.0 to use that as a testbed, and that has a few challenges. Specifically, the vCenter Server Appliance (VCSA) no longer ships directly as a .OVA file. It is now an ISO file that you're supposed to mount and run on a Windows machine to remotely install the vCenter Server Appliance on a remote ESXi server.

I didn't want to get a Windows machine involved if at all possible, and it turns out to be fairly straightforward to do this. You will find 99% of the instructions in this great article:

http://www.unixarena.com/2015/05/how-to-deploy-vcsa-6-0-on-vmware-workstation.html

Specifically, the .OVA file can be found in the .ISO file that you download from VMWare. It just doesn't have a .ova extension. So you need to extract the file, change the name to include the .ova extension, and then you're mainly off to the races. HOWEVER, you have to do ONE MORE THING to actually get it working. Specifically, you need to add this additional line to the end of the .vmx file after you import the .ova file:

guestinfo.cis.appliance.net.dns.servers="172.16.30.8"

Set the value appropriately for your network. If you don't add this, the VM will start up, but will have the error:

Failed to configure network

And I couldn't find a way to fix that in the VM as it stood. I updated the DNS settings, rebooted the server, did lots of other things, etc., and it still just showed that error. So I knew I would have to recreate the VM from the OVA file, but needed to figure out how to set the DNS server of the VM from the VMX file.

So I mounted the VCSA ISO file on Linux and ran the following command at the root of it:

grep -r guestinfo.cis *

Somewhat amazingly, that came back within seconds and I found all of the settings from the linked article, and then I searched for "dns" and found the above REQUIRED setting.

I didn't have a "good" DNS server on my network, so I quickly created a DNS server on one of my RHEL7.1 systems. It's REALLY easy to do this if you have all of your hosts in the /etc/hosts file. You just need to run the command:

service dnsmasq start

systemctl start dnsmasq

(Edit 9/26: I changed the above command to use the systemd mechanism for starting the service)

And that's it. You now have a DNS server.

You still NEED a Windows machine for vSphere


I thought that the vSphere Web Client would allow me to just use a browser, but that's not quite right. the web interface requires Flash, and really only supports Windows or MacOS clients. So I've had to bring a Windows machine into the mix anyway.

There's an updated cloud in town Part 1: Installing ICO 2.5

IBM Cloud Orchestrator 2.5 was recently released, so I'm installing it in my lab. This new release is based on IBM Cloud Manager with OpenStack 4.3, so quite a bit has changed. This series of posts will discuss some of the issues with installation and overall thoughts as I go through.

Wrong Version of IBM Cloud Manager 

IBM Cloud Manager is included in the eAssembly for ICO, but it's not the required level! The Cloud Manager files included with ICO are JUST version 4.3. However, version 4.3 with at least fixpack 2 is what's required. So after installing Cloud Manager, you will need to go to IBM Fix Central to download Cloud Manager 4.3 fixpack 3, which was released after ICO 2.5.

Cloud Manager: Additional YUM Repository Needed for KVM

If you're deploying a KVM cloud to Red Hat 7 or 7.1, you will need to enable the Red Hat "Optional" repository to have access to several python packages, including python-zope-interface and python-pyasn1-modules.

If your target machines don't have access to the Red Hat Subscription Network, you can get around this by downloading Fedora 19 and add it as a Yum repository. But the Fedora ISO doesn't include the python-pyasn1-modules rpm. So you'll need to download that and add it to a local repository on the ICM Deployer machine. I used the 'createrepo' command to create the repository under /opt/ibm/cmwo/yum-repo/operatingsystem/redhat7.1/x86_64/optional .

I downloaded the Fedora 19 ISO from here: http://www.itsprite.com/free-linux-download-fedora-19-iso-cddvd-images/

And I downloaded the python-pyasn1-modules RPM from here: ftp://ftp.icm.edu.pl/vol/rzm5/linux-fedora-secondary/releases/19/Everything/armhfp/os/Packages/p/python-pyasn1-modules-0.1.6-1.fc19.noarch.rpm I think a better link is: https://archives.fedoraproject.org/pub/archive/fedora/linux/releases/19/Everything/x86_64/os/Packages/p/python-pyasn1-modules-0.1.6-1.fc19.noarch.rpm

I didn't need any other packages - the Fedora 19 ISO and the python-pyasn1-modules RPM gave my install everything it needed.

Loading the SCCD 7.5.1 Demo Content Package into SCCD (ICD) 7.5.3

This tip is specifically for SCCD 7.5.3.

Problem

When trying to install the SCCD 7.5.1 Content Pack into SCCD 7.5.3, you'll get an error about the column named GMAPSDISTANCEMATRIX. Specifically, the error will state that there is no default value and no values for that column in the data. The first round of errors come from the Data/SCCD_SI_MAPMANAGER.xml file in the content pack. If you manually download the content pack, you can view the file to see that the data it's complaining about really isn't there. And once you fix the errors found in that file, there are other errors.

Workaround

Since this is just demo data on a demo system, I figured it was OK to modify the offending Maximo objects, and the modifications worked to eliminate the error and allow me to go through all of the scenarios. You should be on a demo system, so you should be OK with that stipulation.

To workaround the problem, you need to make two different types of database modifications within Maximo.

First, turn on Admin mode following these instructions:

https://www.ibm.com/developerworks/community/blogs/a9ba1efe-b731-4317-9724-a181d6155e3a/entry/how_to_turn_on_and_turn_off_maximo_admin_mode31?lang=en


Next, you need to mark that the following attributes are NOT required:

BMAPSDISTANCEMATRIX
BMAPSROUTE
BMAPSGEOCODE
GMAPSDISTANCEMATRIX
SPATIALDISTANCEMATRIX


Go To Applications->System Configuration->Platform Configuration->Database Configuration and search for the MAPMANAGER object:


Select the object found and look for the each one of the listed attributes Attribute. You'll need to go to the second page of attributes to find SPATIALDISTANCEMATRIX.

You can then de-select "Required?" flag which will make it a non-required attribute (which corresponds to a column in the database). Once you've done this for the four attributes, click the Save button.

Now open the ASSET object and you need to add an attribute named AMCREW. Go into the ASSET object and add a new row named AMCREW. All of the default values work fine. This attribute won't hold any data - it just needs to be there.



Then go back to "List View" and select "Apply Configuration Changes on the left under "More Actions":



Once the process completes, you should see dialogs similar to the following:


At this point you can successfully install the content pack.

A great document from IBM on integrating SCCD processes with traditional Maximo asset management functions

IBM Control Desk (previously named SCCD - SmartCloud Control Desk) is Maximo, but because it provides several additional customizations to Maximo, many traditional Maximo developers are intimidated by it. But that shouldn't be the case. Like other Maximo additions (Maximo for Oil and Gas, etc.), ICD is mainly a collection of additional pages (officially named "applications") that access the same Maximo database that you know and love. It does deal with some different objects (tables) in the database, but it's all the exact same architecture. And while it does add new workflows and a few other things, these are all really just "normal" Maximo customizations. It just happens to be that ICD contains quite a few of these customizations, and that's why IBM packages it as its own product.

Have a look at this paper for more information on the use of automated vs manual processes when dealing with ICD and asset management:
