If the node is a CA and the status has been gray for more than a few minutes, then it is likely that the deployment process has failed. Peers and ordering nodes take longer to deploy, but this condition can also occur when the health checker that runs against the peer or ordering nodes cannot contact the node. The request for status can fail with a timeout error because the node did not respond within a specific time period, the node could be down, or network connectivity is down.

 How to fix it 

If this is a new node, wait a few more minutes for the deployment to complete. You can try reloading the page in your browser to refresh the status. If the node is not new, [examine the associated node logs](https://cloud.ibm.com/docs/blockchain?topic=blockchain-ibp-console-manage-consoleibp-console-manage-console-node-logs) for errors to determine the cause.





 When I hover over my node, the status is Status undetectable, what does this mean? 

 What’s happening 

The node status in the tile for the peer or ordering node is yellow, meaning the status of the node cannot be detected. Ideally, when you hover over any node, the node status should be Running.

 Why it’s happening 

This condition can occur on peer and ordering nodes that were imported to the console and the health checker cannot run against the node. This status happens because an operations_url was not specified when the node was imported. An operations URL is required for the node health checker to run. The node itself is likely Running, but because the operations URL was not specified, its status cannot be determined. This problem can also occur if you migrated your IBM Cloud Kubernetes cluster Ingress from IBM Cloud Kubernetes Service Ingress to the community Kubernetes Ingress image, or vis versa.

 How to fix it 

If you imported the node:
You can resolve this problem by performing the following steps:



1. Click the node tile to open it.
2. Click the Settings icon.
3. Click Associate identity, view and make note of the identity that is associated with this node.
Along with using our own global backbone network, IBM Cloud also segments public, private, and management traffic onto different network ports. That means that different types of traffic are transferred without interfering with one another.





 Summary: network latency 

Your customers want your data as quickly as you can get it to them. The time that it takes for your data to get to them across the internet is called network latency. The more control that you have over your data’s network path, the more consistent (and lower) your network latency can be.



* With Direct Link, we give you control over the path your data travels, so your data’s travel is not interrupted or blocked by other traffic.
* IBM Cloud offers industry-leading service providers-- providing high performance, security, and resiliency.
* At IBM Cloud, we continue to add network Points of Presence (PoPs) across the globe to bring your customers’ data closer to your customers; thereby, improving latency and overall performance to meet the needs of your hybrid cloud workloads.

FAQs for Block Storage for VPC Snapshots 

The following questions often arise about the Block Storage for VPC Snapshots offering. If you have other questions you'd like to see answered here, provide feedback by using the Open doc issue or Edit topic links at the end of the topic.



 What is a snapshot? 

Snapshots are a point-in-time copy of your Block Storage for VPC boot or data volume that you manually create. To create a snapshot, the original volume must be attached to a running virtual server instance. The first snapshot is a full backup of the volume. Subsequent snapshots of the same volume record only the changes since the last snapshot. You can access a snapshot of a boot volume and use it to provision a new boot volume. You can create a data volume from a snapshot (called restoring a volume) and attach it to an instance. Snapshots are persistent; they have a lifecycle that is independent from the original volume.





 What is a backup snapshot? 

Backup snapshots, also called backups, are scheduled snapshots that are created by using the Backup for VPC service. For more information, see [Backup for VPC](https://cloud.ibm.com/docs/vpc?topic=vpc-backup-service-about).





 What is a bootable snapshot? 

A bootable snapshot is a copy of a boot volume. You can use this snapshot to create another boot volume when you provision a new instance.





 What is a fast restore snapshot? 

A [fast restore snapshot](https://cloud.ibm.com/docs/vpc?topic=vpc-snapshots-vpc-restore&interface=uisnapshots-vpc-use-fast-restore) is a clone of a snapshot that is stored within one or more zones of a VPC region. The original snapshot is stored in IBM Cloud Object Storage. When you perform a restore, data can be restored faster from a clone than from the snapshot in Object Storage.





 How many snapshots can I take? 

You can take up to 750 snapshots per volume in a region.
: When you run oc get nodes, you might notice that the ROLES of your worker nodes are marked as both master,worker. These nodes are worker nodes in IBM Cloud, and don't include the master components that are managed by IBM. Instead, these nodes are marked as master because they run OpenShift Container Platform components that are required to set up and manage default resources within the cluster, such as the OperatorHub and internal registry.

Cluster networking
: Your worker nodes are created in a VPC subnet in the zone that you specify. Communication between the master and worker nodes is over the private network. If you create a cluster with the public and private cloud service endpoints enabled, authenticated external users can communicate with the master over the public network, such as to run oc commands. If you create a cluster with only the private cloud service endpoints enabled, authenticated external users can communicate with the master over the private network only. You can set up your cluster to communicate with resources in on-premises networks, other VPCs, or classic infrastructure by setting up a VPC VPN, IBM Cloud Direct Link, or IBM Cloud Transit Gateway on the private network.

App networking
: Virtual Private Cloud load balancers are automatically created in your VPC outside the cluster for any networking services that you create in your cluster. For example, a VPC load balancer exposes the router services in your cluster by default. Or, you can create a Kubernetes LoadBalancer service for your apps, and a VPC load balancer is automatically generated. VPC load balancers are multizone and route requests for your app through the private node ports that are automatically opened on your worker nodes. If the public and private cloud service endpoints are enabled, the routers and VPC load balancers are created as public by default. If only the private cloud service endpoint is enabled, the routers and VPC load balancers are created as private by default.
You can use and manage the cross-regional snapshot in the target region independently from the parent volume or the original snapshot.

Creating a cross-regional copy affects billing. You're charged for the data transfer and the storage consumption in the target region separately.

You can create and manage cross-regional snapshot copies in the UI, from the CLI, with the API, or Terraform.





 Tags for Block Storage for VPC snapshots 

You can apply [user tags](https://cloud.ibm.com/docs/vpc?topic=vpc-snapshots-vpc-about&interface=apisnapshots-about-user-tags) and [access management tags](https://cloud.ibm.com/docs/vpc?topic=vpc-snapshots-vpc-about&interface=apisnapshots-about-mgt-tags) to snapshots of your Block Storage for VPC volumes to better control and organize them across the VPC.



 User tags for snapshots 

User tags are uniquely identified by a Cloud Resource Name (CRN) identifier. When you create a user tag, you provide a unique name within your billing account. You can define user tags in label or key-value format. You can create user tags or add existing tags to snapshots. You can also add tags when you use a snapshot of a volume during [instance creation](https://cloud.ibm.com/docs/vpc?topic=vpc-snapshots-vpc-manage&interface=uisnapshots-vpc-instancevol-tags-ui).
One NSX Manager maps to a single vCenter Server environment and multiple NSX Edge, vShield Endpoint, and NSX Data Security instances.





 NSX vSwitch 

NSX vSwitch is the software that operates on IBM Cloud ESX hosts to form a software abstraction layer between servers and the physical network. As the demands on data centers continue to grow and accelerate, requirements that are related to speed and access to the data itself continue to grow as well. In most infrastructures, virtual machine access and mobility usually depend on physical networking infrastructure and the physical networking environments they reside in. This dependency can force virtual workloads into less than ideal environments due to potential layer 2 or layer 3 boundaries, such as being tied to specific IBM Cloud Private Networks (VLANs) in specific pods. NSX vSwitch places these virtual workloads on any available infrastructure in the data center, regardless of the underlying physical network infrastructure. This ability not only allows increased flexibility and mobility, but increased availability and resilience.





 NSX controller 

NSX controller is an advanced distributed state management system that controls virtual networks and VXLAN overlay transport tunnels. NSX controller is the central control point for all logical switches within a network and maintains information of all virtual machines, hosts, logical switches, and VXLANs. The controller supports three logical switch control plane modes, Multicast, Unicast, and Hybrid. These modes decouple NSX from the physical network. IBM Cloud requires Unicast mode as IBM Cloud Private Networks (VLANs) do not offer IGMP services for Multicast or Hybrid mode. The NSX Controller uses Unicast mode with virtual tunnel endpoints (VTEPS) to provide MAC learning and other functions to allow VXLAN Broadcast, Unknown unicast, and Multicast (BUM) traffic within a logical switch. The unicast mode replicates all the BUM traffic locally on the host and requires no physical network configuration outside of Layer 3 connectivity between VTEPS. NSX Controllers are deployed by the NSX Manager as a minimum set of three controller nodes, and various other nodes to support (distributed) Layer 3 routing services. All of the nodes are deployed as virtual machines and are managed by the NSX Manager on an ESX Management Cluster at IBM Cloud.
Figure 2. Team Directory team list and cache information

In a real cloud-based application, the application server and the Databases for Redis instance would be close to each other (in the same data center) so latency between the two would be only a few milliseconds. In this example, extra network hops exist between your locally hosted application server and the cloud-hosted Databases for Redis cache so latency gains aren't as good as in production.

The cached data is set to expire within 60 seconds. So if you return to one of the teams after 60 seconds, the data is again retrieved from the database and not the cache.
5. Use the Clear Cache button to remove all cached data from Databases for Redis if necessary.







 About the Code 

The application is a simple Node.js application. It uses three main packages:



* [@ibm-cloud/cloudant](https://github.com/IBM/cloudant-node-sdk) to connect to IBM Cloudant and read/write data.
* [redis](https://www.npmjs.com/package/redis) to connect to the Databases for Redis instance and read/write data.
* [Express](https://expressjs.com/) to enable a simple web server that allows users to interact with the data.



The following sections describe the two main files.



 server.js 

This server.js file runs the web server and communicates with IBM Cloudant and Databases for Redis. When the front end submits a team selection to the team route (see [index.html](https://cloud.ibm.com/docs/Cloudant?topic=Cloudant-combine-ibm-servicesindex-html-redis)), the app.route function first checks the cache to see whether it has the data already. If it does, then it returns that. Otherwise, it makes a query to IBM Cloudant to retrieve team data, store it in the cache, and return it to the front end.

The read operation uses an IBM Cloudant design document and a MapReduce view to select documents.
: Previously, KMIP for VMware provided a multitenant service that enables VMware vCenter Server to use IBM Key Protect for IBM Cloud (Key Protect) and IBM Cloud Hyper Protect Crypto Services (HPCS) as its key manager.

Newly created KMIP for VMware instances that are connected to HPCS now operate as single-tenant services. These services run within the HPCS service and benefit from the features of IBM Secure Service Containers on IBM LinuxONE servers. You can connect only a single KMIP for VMware instance to each HPCS instance.

KMIP for VMware continues to provide a multitenant service when you connect to Key Protect.

In addition, two new endpoints are now available in the Osaka location for KMIP for VMware.

* Load-balancer - An NSX ESG load-balancer service is used to front end the Red Hat OpenShift APIs, both internal and external, and the Red Hat OpenShift router. The load balancer is configured so that Port 6443 and 22623 point to the bootstrap and control plane nodes, while ports 80 and 443 are configured to point to the worker nodes.
* Webserver - A web server is needed to hold the ignition configurations and installation images for the installation of RHEL CoreOS. NGINX is installed on the bastion node to provide this function.
* Persistent Storage - To support the persistent storage requirements, the vSphere cloud provider is used to provide storage volumes up to the Red Hat OpenShift platform backed by any supported vSphere datastore that is, VMware® vSAN™, NFS, or iSCSI. Red Hat OpenShift can deliver storage through static or dynamic provisioning. The preferred method is to use dynamic provisioning. Dynamic provisioning automatically triggers the creation of the persistent volume and its backend VMDK file. For dynamic provisioning, a default StorageClass for the Red Hat OpenShift cluster is defined and a PersistentVolumeClaim in Kubernetes is created.



Access to the environment for this build process is done through a "jump-server" or remote device:



* You can have a Microsoft Windows® or Linux Virtual Server Instance (VSI) installed alongside your vCenter Server instance to provide administrative access to the environment. This VSI has internet access for the remote connection to the server and for downloading files. It also has private network access for connecting to vCenter and to the bastion node.
* You can have a remote device (laptop or desktop) connected through the IBM Cloud SSL VPN to the IBM Cloud Private network. This remote device has access to the internet to download the required files and can connect to vCenter and the bastion node through the SSL VPN.







 Scripts overview 

This build process uses the following scripting tools and scripts:



* govc is a vSphere CLI pre-compiled for Linux, OSX, and Windows.

For some functions, there is parity but you follow different steps to implement the behavior you want.



* Jump-to: In actions, you can jump from one step to another. In a dialog, you use a jump-to to skip to a specific dialog node in the same branch of the conversation. With actions, you can jump to a different step within an action also. However, to do so, you use conditions on the intervening steps to prevent them from being processed, rather than using an explicit jump-to. The benefit of this approach is that it's easier to anticipate the path of a conversation and follow it later if there are not multiple jump-tos sprinkled throughout the flow.
* Slots: In a dialog, you add slots to a dialog node to call out a set of values that you want to collect from the user, and that you will take and store in any order. In actions, every step in the action acts like a slot.
