Greetings Community!  Greg here, Product Manager for Discovery (intro post from April).

 

We have recently released a new Distributed Storage model for Discovery via the May TKU (Release Notes).  The Distributed Storage Model is a set of multiple physical systems where storage capacity and computing power are grouped together to behave as one single storage system (cluster).  We have this new model available across multiple storage systems from vendors such as EMC, NetApp, & Nimble.  For more information on the Distributed Storage model, the new dedicated page on these technologies can be found here.

After you've had a chance to try out the May Storage TKU with some of these storage systems, we'd love to hear your feedback on how it's improving the discovery of your datacenter.  Feel free to post below and let us know your thoughts!

When importing root node keys from a large environment, tw_root_node_key_import may run for many hours before completing. If it is not run using 'screen', the session may timeout, and the import may fail without error or notification. As a result, not all of the root node keys may be imported.

 

BMC now recommends to run "screen" before running tw_root_node_key_import to prevent this session timeout failure. See https://docs.bmc.com/docs/display/DISCO113/Using+screen.

I would like to take this opportunity to introduce myself to this very active and engaging community.  My name is Greg DeaKyne.  I was born and raised in Indiana and escaped the cold winters for sunny Charleston, South Carolina almost 8 years ago.  When I’m away from the keyboard, I’m staying busy running around town with my two daughters (4 & 6) between ballet practice, gymnastics, guitar practice, soccer practice, and hopefully a few trips to the beach.  Before kids, I used to spend my free time on the golf course, but my game has gotten pretty rusty over the past 6 years. 

 

I started using BMC software as a customer over 10 years ago but will be frank with you that I haven’t had the opportunity to touch it in a few years. I led the team that rolled out ADDM, CMDB, BladeLogic, and Atrium Orchestrator.  We were utilizing the toolset during a transformation of our IT teams as we integrated many acquisitions, datacenter consolidation, increased security posture, and enabled front line support via tools and automation.

 

I have spent the majority of the past 15 years leading multiple IT teams delivering many global SaaS offerings across multiple colo, managed service, and public cloud environments.  I was managing teams responsible for all aspects of the datacenter including compute, storage, database, operating system, application, and networking. 

 

I have seen the power that Discovery can provide any size organization and I look forward to working with you all (y’all for my Charleston neighbors) as we improve this product through one of the most active communities at BMC.

 

Today is the start of my third week at BMC and so you will start to see me interacting more in the coming weeks as I continue to learn more about what we are currently working on and sharing with you what the future of BMC Helix Discovery will be.

The December OSU updates many packages, and upgrades the operating system to CentOS 7.6. Included in the upgrade to 7.6  is an update to the sudo package.

 

The change in sudo includes: “PAM account management modules are now run even when no password is required.” [See the Red Hat documentation for more information]

 

For some processes in BMC Discovery, the tideway user uses sudo to run certain system level programs. Where user passwords expire, the changed processing of the PAM modules would request users to change the password, which in turn would have caused automated sudo usage to fail. This would be particularly problematic for customers that have strict expiry policies (STIG) on the appliance command line users.

 

The update to sudo-1.8.23-3.el7 (and only sudo) has been excluded from the December OSU while the we determine the full extent of the changes required.

 

Update: 8th April 2019. The April OSU will now contain any updates to sudo.

From the Aprill 2019 OSU, Discovery will utilise the pam_localuser.so module in the PAM sudo stack against a specific list of users (pam_localuser).

Hello Discovery community!

 

If you have been browsing bmc.com and are following BMC social media you will notice a lot of buzz around Helix Discovery.  Marketing and sales were too excited to wait and are shouting out the availability of Helix Discovery.  The cat is out of the bag on the worst kept secret in the industry   I would like to officially announce the launch of BMC Helix Discovery, our cloud native service offering.  More technical details to come in the coming weeks as well as a technical deep dive in early December.

 

I encourage you to take a look at the new web page and marketing content here:

 

Helix Discovery - BMC Software

 

Worth noting, the on-premise version, "BMC Discovery" is alive and well, there is no plans to deprecate this offering and we see many valid use cases for customers choosing to continue to use the on-premise version.  We intend to align functionality and features between the two solutions.  For example capabilities like TPL pattern development and application modeling will be the same in both SaaS and on-premise.  Please feel free to post any questions you may have, we look forward to your comments.

Greetings Community,

 

We have released a patch update across all our supported versions of BMC Discovery to address important defects, including security fixes.

 

The files are available for download on the BMC Electronic Product Distribution (EPD) site and we encourage you to patch your environment at your earliest opportunity.

 

Follow the links below to release notes on the various patches:

https://docs.bmc.com/docs/display/DISCO113/Defects+resolved+in+this+version

 

In addition, in 11.3 patch 1, Discovery now provides capabilities that help administrators address the personal data protection and privacy requirements associated with the General Data Protection Regulation (GDPR). The GDPR is a set of rules and principles governing the handling of personal data of individuals located in the European Union (EU). Find out more here.

 

We strongly recommend that you upgrade to version 11.3 Patch 1 if you are on any previous versions of BMC Discovery 10.0, 10.1, 10.2, 11.0, 11.1 or 11.2 For details about the upgrade procedure, see the Upgrading BMC Discovery page.

For several years, Discovery has had an integration with RSA SecureID for 2 factor authentication to the appliance. However, at 11.3 it has been deprecated, and I cannot recommend its use because:

 

  • It has only ever been tested with Authentication Agent V7.1 for Apache
  • This version is old and no longer supported by the vendor
  • It is not supported on the current appliance OS
  • BMC has no RSA infrastructure to perform regression or other tests.

 

In the 11.3 docs we instead recommend RSSO. Unfortunately, it is not possible to use RSSO (it was in ASSO but the feature was not carried over to RSSO). I have logged a defect to get the docs updated, but it means anyone currently using the integration will have to think about how they can move off this mechanism.

 

If you are currently using this integration, or would want to in the future if there was a fully supported implementation, please contact me directly. I want to collate responses and pass to Product Management.

Details of a critical vulnerability in the dhcp clients shipped on RHEL, and CentOS, 6.x and 7.x have been released and designated CVE-2018-1111. This affects all currently supported versions of the Discovery appliance. We have decided to bring the release of the May OSU forward to accommodate and will release ASAP. We strongly recommend that customers update, particularly in environments that use DHCP.

 

CVE details:

https://access.redhat.com/security/cve/cve-2018-1111

https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-1111

https://nvd.nist.gov/vuln/detail/CVE-2018-1111

 

Red Hat security errata:

7.x: https://access.redhat.com/errata/RHSA-2018:1453

6.x: https://access.redhat.com/errata/RHSA-2018:1454

 

The vulnerability allows a malicious DHCP server to manipulate a NetworkManager integration script (shipped with the dhcp clients) to run arbitrary commands as root when the interface in question has DHCP enabled and is managed by NetworkManager.

 

The 6.x May OSU contains updates for the kernel (CVE-2018-8897), the dhcp client update and a timezone update.

The 7.x May OSU is substantial, and moves the base OS from CentOS 7.4 to 7.5 – and includes the kernel and dhcp client updates listed above.

 

Update: 22nd May 2018
The OSU should now be available on EPD. For those interested, updates for CVE-2018-3639 (Spectre/Meltdown variant) are *not* included in this update. We will shortly release the May monthly OSU which will contain those fixes.

 

Update: 23rd May 2018

Please note, I refer to the May OSU in the blog post and then, in the update, say "we will shortly release the May monthly OSU". We chose to bring the May OSU forward but then the Spectre/Meltdown variants were announced and patches made available. There is another May OSU coming (e.g. 6.18.05.xx where xx is later than the 16th) that contains these fixes (and one or two other updates) but will be released at the "usual" time in tandem with the TKN.

 

Apologies for the confusion

Hello Everyone,

 

I am pleased to announce BMC Discovery 11.3 is now generally available.  This release is a true testament to our ability to introduce features and content that align with the ever changing new technologies introduced in the market while also having an ear to the ideas coming directly from customers.

 

A discovery webinar on What's New with BMC Discovery 11.3 is scheduled for April 5, 2018 where we will go into detail on the features briefly explained in the next section.  Below is a link to register to the webinar, more details on the What's New webinar can be found at the end of this post.

Below is a brief guide on some of the major features implemented in version 11.3:

 

 

BMC Discovery 11.3 - What's New

 

Container Infrastructure Discovery

BMC Discovery 11.3 expands discovery capabilities to container management solutions like Kubernetes, OpenShift, and CloudFoundry and their supporting compute on public cloud, private cloud, traditional datacenter, and hyper-converged infrastructure such as Nutanix.  Container management software has previously been discovered and modeled as Software Instances using TKU patterns. The introduction of container discovery with BMC Discovery 11.3 extends this to discover the containers that the management software is controlling. Discovery of containers is triggered by the creation or update of an SI representing the container management software, and then additional patterns query the container management software to determine the containers it is running.

Direct REST API Discovery

With BMC Discovery 11.3 we will begin to introduce content that is driven by direct discovery through REST APIs.  This will address the trends we are seeing with major storage and network infrastructure vendors to provide more discovery and dependency mapping information via their REST APIs.  An example of a storage device that can only be discovered by using direct REST API calls is Nimble storage devices.

 

When a Nimble storage device is discovered as part of a discovery scan, a Storage System node is created. TKU patterns then trigger to deeply discover the details of the storage system. For custom extensions, you can write a pattern which triggers on the storage system representing the Nimble device, and the pattern can then query the device using its REST API using the enhanced discovery.restfulGet TPL function.

 

The 11.3 release ships with a new credential type to enable you to discover Nimble storage devices using their REST APIs. Further new credential types will be provided in future knowledge updates without requiring a new product release.

 

 

Model Changes

The following major changes have been made to the BMC Discovery model:

 

Software Container

On upgrade to BMC Discovery 11.3, existing Detail and Virtual Machine nodes that represent containers are converted to the new Software Container node kind.

 

Hardware Container

The new Hardware Container node represents a single physical device which contains multiple hosts, network devices and other components. For example, a blade enclosure which is discovered via a management controller, or a hyper-converged device containing compute and storage. The Host Container node is used to represent a computer that is logically partitioned into a number of hosts, as opposed to containing physically separate devices. On upgrade to BMC Discovery 11.3, existing HostContainer nodes that were used to represent physical devices containing hosts, network devices and other components are converted to the new Hardware Container node kind.

Remedyforce CMDB Sync

CMDB synchronization is now extended to BMC Remedyforce with simple UI-based configuration in BMC Discovery.  With the enhanced integration between Remedyforce and BMC Discovery, devices, components, services and relationships that are discovered in BMC Discovery can be automatically imported into and synchronized with Remedyforce CMDB. This integration no longer requires Pentaho. The configuration is done within the solutions and the data mappings and transfers are achieved with APIs.

 

 

CentOS 7 Migration Options

The OS has been updated to CentOS 7 for new installs, and remains CentOS 6 for upgrades. An easy backup/restore option is available to migrate appliances to CentOS 7.

 

The replacement of earlier OS versions with CentOS 7 ensures continued support for the appliance OS during its lifetime, and provides support for newer hardware where you choose to install on hardware. It also provides SMB 2 support, and Apache Web Server version 2.4.

 

 

Additional Features Introduced from Community Ideas

Stacked switches

BMC Discovery 11.3 now fully discovers stacked switches. Previous versions discovered stacked switches, but were unable to differentiate the stack master and members. Stacked switches now have the attribute stack to indicate whether it is part of a stacked switch, and the stack master has the attribute stack_master. Network device node pages for stacked switches also provide a list of, and links to other members of the stack. For more information, see Viewing a network device.

Discovery of stacked and virtual switches

Virtual network devices

BMC Discovery 11.3 now fully discovers virtual network devices. Previous versions could identify the network device, but not that it was virtual. Virtual network devices now the attribute virtual to indicate whether it is virtual. Network device node pages for virtual network devices also show and link to the virtual machine containing the device. For more information, see Viewing a network device.

open-vm-tools

On CentOS 7 appliances, the open source open-vm-tools utility replaces VMware's VMware Tools. This is in line with VMware's recommendation that open-vm-tools be used on Linux hosts in preference to VMware Tools.

I saw Tool in 2007 at Brixton Academy; great show. Somewhat less enjoyable (depending on your musical taste, I suppose) is having to install VMware Tools on VMware-deployed appliances. We document the procedure here.

 

So far, so good. Unfortunately, whenever a new kernel is installed (product version upgrade or OSU) VMware tools needs the modules recompiled for the new kernel. After you have rebooted, you will see a red baseline icon like this:

 

Baseline1.PNG

which you can click through, and observe the warning that it's not running:

Baseline2.PNG

However, you are not given any information as to why, and you may miss this completely if you are not in the habit of monitoring and correcting all major baseline events. So for the moment, you will just have to keep in mind that you should re-run the

 

vmware-install.pl

 

install script after an OSU upgrade. Note: you can use the "-d" flag to take all the defaults without being prompted.

 

For reference, we have DRUD1-22356 to try and make the user experience better in this regard.

[Note: edited, after discussion with Kerryn Wood]

 

I wish to draw your attention to a problem applying 2018-01 TKU on an appliance earlier than 11.2: an upstream package naming problem leads to a failure and a non-working appliance *if* this is subsequently upgraded to 11.2.X. This is not good.

 

To reiterate: the 2018-01 OSU will install fine on 11.1, and you might want to do that for Meltdown/Spectre mitigations. But you should not attempt an upgrade to 11.2.X on a 11.1.X / 2018-01 OSU appliance. I expect we will issue a new OSU you will need to install on 11.1.X before upgrading to 11.2.X in this situation. [UPDATE: New OSU 6.18.01.30_727098 is now available on EPD and replaces the previous one]

 

It would be fine to take an 11.X appliance on a pre-2018-01 OSU, upgrade to 11.2.X and apply 2018-01 OSU to it.

 

While OSUs are normally very easy to apply (UI upload; wait a bit; reboot) this reminds us that no change is completely without risk, and updates should always be applied on UAT first - before considering a production upgrade.

 

For reference, this is tracked as defect DRUD1-22350.

I admit it: we don't get many issues around OpenVMS,

 

Although I can't say I have really used it, I get vaguely nostalgic for the dusty old MicroVax that sat next to me for a while at the University of Nottingham. And even earlier I think I remember seeing Jodrell Bank using them for telescope control. So in contrast to the usual periodic Apple, Microsoft or Linux (and now Intel) security vulnerabilities, this problem caught my eye.

 

If you work in a large organisation, you might still have a few of these machines refusing to get replaced, and/or have very specialised uses. You might want to check you are comfortable with the risks, and not assume they are completely impenetrable. Find them with something like:

 

  • search Host where os_type matches regex "OpenVMS"

 

Note we also End-of-Life data for the OS up to 7.3-2 in EDP module SupportDetail.OS.HP.OpenVMS. I am going to talk to the TKU team about getting this table updated for later versions; it appears that the current version 8.4-2 is supported into 2021.

 

If you have any experiences with this OS, I would be interested to hear from you.

For a long time, the TKU Extended Data Pack has been able to mark software end-of-life, such as this for one of my ESX servers:

 

SW.PNG

However it may have gone unnoticed to you (I certainly had missed it, until a customer question prompted me to check) that the EDP now supports some hardware end-of-life data, for example:

 

HW.PNG

 

2018-Jan EDP has some data for different kinds of hardware:

 

No doubt, this list will expand over time. If you have an EDP license, you might want to check how the current list covers your estate, and log important missing devices with Support as RFEs. For example, to find Hosts that have no EOL data, try this query:

 

search Host where not virtual and vendor and model and not nodecount(traverse ElementWithDetail:SupportDetail:HardwareDetail:SupportDetail) show vendor, model processwith countUnique(0, 0)
