No. There is currently no way to migrate existing components to a new Red Hat OpenShift cluster in IBM Cloud.





 What happens when I delete my IBM Blockchain Platform service? 

When you delete an IBM Blockchain Platform service instance, all of the blockchain CAs, peers, smart contract pods (if using peers deployed with a Fabric 2.x image; smart contracts deployed on peers using a Fabric 1.4.x image are located inside the peer container), and ordering nodes are deleted along with their associated storage. If you have exported any nodes to other consoles, make sure to reach out to the administrators of those consoles to let them know that those nodes are no longer functioning, because deleting them in your console does not automatically delete them in theirs.





 Can I use my existing Kubernetes cluster on IBM Cloud? 

Your existing Kubernetes cluster works with the IBM Blockchain Platform if it satisfies the following conditions:



* It is running Kubernetes version v1.24 - v1.26.
* There are enough available resources in the cluster.







 What database do the peers use for their ledger? 

You have the choice of either CouchDB or LevelDB when you configure your peer database. Because data is modeled differently in a Couch database than in a Level database, the peers in a channel must all use the same database type. See [LevelDB versus CouchDB](https://cloud.ibm.com/docs/blockchain?topic=blockchain-ibp-console-adv-deploymentibp-console-adv-deployment-level-couch) to decide what is best for your business needs.





 What types of off-chain databases are supported with the IBM Blockchain Platform? 

As a best practice it is recommended that you do not query the entire blockchain ledger for the purpose of aggregation or reporting. If you want to build a dashboard or collect large amounts of data as part of your application, you can query an off chain database that replicates the data from your blockchain network. This allows you to understand the data on the blockchain without degrading the performance of your network or disrupting transactions.
* Is data migration supported for File or Block performance endurance storage?

Only local storage and Block performance endurance storage is supported in IBM Cloud classic. File performance and endurance volume’s data migration is not supported; for this, consider using a third-party tool such as rsync. A sample script using rsync can be found [here](https://github.com/IBM-Cloud/vpc-migration-tools).
* What is RMM server?

RackWare Management Module (RMM) server is a software appliance that is offered by RackWare that replatforms your server from an IBM Cloud® classic physical bare metal server to an IBM Cloud VPC virtual server instance.
* Where can I find more information about RMM server?

For RMM server overview information, see [RackWare's Cloud Migration documentation](https://www.rackwareinc.com/cloud-migration). For RMM server usage guide information, see [RackWare RMM User's Guide for IBM Cloud](https://www.rackwareinc.com/rackware-rmm-users-guide-for-ibm-cloud).
* How do I install the RMM server?

This software is available in the IBM Cloud® catalog in the Migration Tools category. After you complete the appropriate information, a virtual server instance is installed in a new VPC with the RMM already installed.
* Is this service free?

You need to Bring Your Own License (BYOL), which you must purchase directly from RackWare. For more information or inquiries, contact [sales@rackwareinc.com](mailto:sales@rackwareinc.com). However, IBM is offering promotional licensing at no cost for three months for three reusable concurrent migration licenses.
* What is the promotional license?

The promotional license is valid only for per-account and first-time users of the RMM server. After the three-month period, you need to purchase the license directly from RackWare.
* How does the reusable concurrent license work?

IBM and RackWare have put together a special license model. Typically, a license is a one-time use for each server migration.
FAQ: Servers (general) 



 My virtual server is down. What do I do? 

If your virtual server is down, use the following steps to bring it back up:



1. Try to access the server by using the [KVM console](https://cloud.ibm.com/docs/virtual-servers?topic=virtual-servers-access-kvm-console). Depending on the output, you might need to create a [support case](https://cloud.ibm.com/docs/virtual-servers?topic=virtual-servers-gettinghelp).
2. Try to power your server off and on. For more information, see [Powering server on or off](https://cloud.ibm.com/docs/virtual-servers?topic=virtual-servers-managing-virtual-serverspower-on-off) or [Rebooting a device](https://cloud.ibm.com/docs/virtual-servers?topic=virtual-servers-managing-virtual-serversreboot).

 What do I do if my bare metal server is down?
You are able to view resource allocations on the host Allocations tab to know how many dedicated host instances are provisioned, current host capacity that is used, and what is available.





 What images can be provisioned on dedicated hosts? 

You can provision IBM Cloud virtual server stock images or import your own images as indicated in the third-party agreement.





 Is there a limit as to how many dedicated hosts can be allocated to a single account? 

Yes, resource limitations are per account as defined for all IBM Cloud as a Service resources. You can have multiple orders per account but only two dedicated hosts per provisioning order.





 Can dedicated host deployments be oversubscribed? 

No; you can provision only the listed capacity on dedicated hosts.





 What happens if my dedicated host fails? 

When a dedicated host failure occurs, we automatically detect this failure and move your instances onto a new dedicated host. This failure detection typically occurs within 1 minute. Your virtual servers are rescheduled to the new dedicated host within 5 minutes, and are up and running within 7 minutes. To opt out of auto-recovery, a support case must be opened with the request.
For more information, see [Configuring route propagation for VPN servers](https://cloud.ibm.com/docs/vpc?topic=vpc-vpn-client-to-site-route-propagation).





 What happens to a VPN server if I try to delete the security group that the VPN server is attached to? 

You cannot delete a security group if any VPN servers are present.





 Why must I choose subnets during VPN server provisioning? 

The server resides in the VPN subnet that you choose. A VPN server needs two available private IP addresses in each subnet to provide high availability and automatic maintenance. It is best if you use the dedicated subnet for the VPN server of size 8, where the length of the subnet prefix is shorter or equal to 29. With dedicated subnets, you can customize the security group and ACL for greater VPN server flexibility.





 Does VPN server support high-availability configurations? 

Yes, it supports high availability in an Active/Active configuration. You must choose two subnets if you want to deploy a high availability VPN server with two fault domains. You can also upgrade the stand-alone VPN server to high-availability mode, and downgrade the high-availability VPN server to stand-alone mode.





 Are there any caps on throughput for VPN server? 

Up to 600 Mbps of throughput is supported with a stand-alone VPN server. A maximum of 1200 Mbps of throughput is supported with a high availability VPN server.





 Can I use a VPN server for IBM Cloud classic infrastructure? 

Yes, you can use a VPN server for IBM Cloud classic infrastructure. However, you must also enable either Classic Access on the VPC, or configure IBM Cloud Transit Gateway to connect the VPC where the VPN server resides.





 What VPN client is supported? 

See [Supported client software](https://cloud.ibm.com/docs/vpc?topic=vpc-client-to-site-vpn-planningvpn-client-software) for details.





 What protocol and port can I use for the VPN server?
Managing Veeam 

After the service is deployed into your instance, you can access the Veeam® console by using Remote Desktop Protocol. With Remote Desktop Protocol, you can manage the backup and restore of all the virtual machines in your environment, including the management components. You can also upgrade the service by downloading and installing the Veeam updates from the Veeam website.

Veeam Backup and Replication 12 is available for deployment on new instances. If you have Veeam 9.5u4b, you can continue to use it. However, you cannot install Veeam 9.5u4b on a new instance.



 Tasks that you can complete with Veeam 



* Order a new VMware vCenter Server® instance with Veeam

A Veeam stand-alone license is automatically deployed. The Veeam service installation starts only after the stand-alone license was successfully ordered.

Veeam is installed on a bare metal server, VM, or VSI, depending on what you selected.
* Install Veeam on an existing VMware® vCenter Server instance

A Veeam stand-alone license is automatically deployed. The Veeam service installation starts only after the stand-alone license was successfully ordered.

Veeam is installed on a bare metal server, VM, or VSI depending on what you selected.
* Uninstall Veeam on an existing vCenter Server instance

If you uninstall an older version of Veeam, for example Veeam 9.5u4b, the license charge for that version is canceled because the license is attached to the older version.

However, if you uninstall Veeam, the stand-alone license instance is not deleted. To cancel the license charge, you must delete the license separately.

For more information, see [Managing Veeam licenses](https://cloud.ibm.com/docs/vmwaresolutions?topic=vmwaresolutions-veeam_managing_licenses).
* Order a new Veeam stand-alone license

An order is placed with the number of VMs to license. A license key is not displayed because no unique keys are generated.

You can also revoke access at any time, for example, if you suspect your keys might be compromised. You can also disable or delete a root key, or temporarily revoke access to the key's associated data on the cloud. For more information, see [Managing root keys](https://cloud.ibm.com/docs/vpc?topic=vpc-vpc-encryption-managingbyok-manage-root-keys).





 What are the advantages of using customer-managed encryption over provider-managed encryption? 

Customer-managed encryption encrypts your Block Storage for VPC volumes by using your own root keys. You have complete control over your data security and grant IBM access to use your root keys. For more information, see [Advantages of customer-managed encryption](https://cloud.ibm.com/docs/vpc?topic=vpc-vpc-encryption-aboutbyok-advantages).





 What encryption technology is used for customer-managed encryption? 

Virtual disk images for VPC use QEMU Copy On Write Version 2 (QCOW2) file format. LUKS encryption format secures the QCOW2 format files. IBM currently uses the AES-256 cipher suite and XTS cipher mode options with LUKS. This combination provides you a much greater level of security than AES-CBC, along with better management of passphrases for key rotation, and provides key replacement options in case your keys are compromised.





 What are master encryption keys and how are they assigned to my Block Storage for VPC volumes? 

Each volume is assigned a unique master encryption key, called a data encryption key or DEK, which is generated by the instance's host hypervisor. The master key for each Block Storage for VPC volume is encrypted with a unique KMS-generated LUKS passphrase, which is then encrypted by your customer root key (CRK) and stored in the KMS. Passphrases are AES-256 cipher keys, which means that they are 32 bytes long and not limited to printable characters. You can view the cloud resource name (CRN) for the CRK that is used to encrypt a volume.
Platform management roles enable users to perform tasks on service resources at the platform level, for example, assign user access to the service, create or delete instances, and bind instances to applications.



Table 1. IAM platform roles
The rows are read from left to right. The first column is the platform management role. The second column is a description of the actions in the service that the platform management role permits.

 Platform role Description of actions 

 Viewer Description of what users can accomplish; think tasks. 
 Operator Description 
 Editor Description 
 Administrator Description 



The following table describes the types tasks that can be completed when each service access role is assigned. Service access roles enable users access to vSRX and the ability to call the service name's API.

For information about the steps to assign IAM access, see [Managing access to resources](https://cloud.ibm.com/docs/account?topic=account-assign-access-resources).
You can enable this feature in NFSv4.1, by editing the domain information and running the rpcidmapd or a similar service. For more information, see [Implementing no_root_squash for NFS](https://cloud.ibm.com/docs/FileStorage?topic=FileStorage-mountingLinuxnorootsquash).

When File Storage for Classic is used in a VMware® deployment, NFSv4.1 might be the better choice for your implementation. For more information about the different features of each version and what is supported by VMware®, see [NFS Protocols and ESXi](https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.storage.doc/GUID-8A929FE4-1207-4CC5-A086-7016D73C328F.html).





 Can VAAI and HW acceleration be enabled in our VMware deployments? 

No. Currently, vStorage for API Array Integration and Hardware acceleration are not supported.





 What happens to the drives that are decommissioned from the cloud data center? 

When drives are decommissioned, IBM destroys them before they are disposed of. The drives become unusable. Any data that was written to that drive becomes inaccessible.





 What is the difference between Controlled Failover and Immediate Failover? 

Controlled Failover does one last sync before it breaks the mirror process. The Immediate Failover immediately breaks the mirror and activates the replica volume.





 My storage appears offline or read-only. Why did it happen and how do I fix it? 

In a couple of scenarios a host (bare metal or VM) might lose connection to the storage briefly and as a result, the host considers that storage read-only to avoid data corruption. Most of the time the loss of connectivity is network-related but the status of the storage remains read-only from the host's perspective even when the network connection is restored.

This issue can be observed with virtual drives of VMs on a network-attached VMware® datastore (NFS protocol).

Why it’s happening 

Look at the reason_codes property in the response. It might be an internal error or the [snapshot limit](https://cloud.ibm.com/docs/vpc?topic=vpc-snapshots-vpc-faqs&interface=uifaq-snapshot-3) is reached.

 How to fix it 

Contact IBM support if you see an internal error. If the backup snapshot limit is reached, delete the oldest snapshots so new ones can be created. You can create up to 100 backup snapshots of a volume.





 Backup policy is not created due to incorrect authorizations 

 What’s happening 

A service authorization error is generated when you try to create a backup policy.

 Why it’s happening 

When you attempt to create a backup policy, an s2s service not completed error is generated, which indicates that incorrect service-to-service authorizations were set up. The backup policy creation fails. This behavior is expected and right, it prevents the backup policy from being created without proper authorization.

 How to fix it 

Establish correct service-to-service authorizations and try creating a backup policy again. For more information about setting up authorizations for the backup service, see [Establishing service to service authorizations](https://cloud.ibm.com/docs/vpc?topic=vpc-backup-s2s-auth).





 Backup policies are not found 

 What’s happening 

You receive a backup_policies_not_found error with the following message: Backup policy with ID is not found.

 Why it’s happening 

The backup policy that you are trying to find is either deleted or never existed.

 How to fix it 

To address this error, list the policies and see whether the backup policy ID that you're looking for is in the list. If you still need help with the error, contact [support](https://cloud.ibm.com/docs/vpc?topic=vpc-getting-help).
In the above example, the default security group was used for the VMKs. This is for easy testing, but in real environments it is recommended to isolate VMK traffic, and only allow traffic what is needed. To be able to do this in IBM Cloud VPC, create separate Security Groups for each interface role, and create rules to only allow the required traffic at the detail level required by your network security policies.









 Next steps 

The next step in the tutorial series is:



* [Provision vCenter Appliance](https://cloud.ibm.com/docs/solution-tutorials?topic=solution-tutorials-vpc-bm-vmware-vcentervpc-bm-vmware-vcenter)
Instead, apply [labels](https://cloud.ibm.com/docs/containers?topic=containers-add_workersworker_pool_labels) or [taints](https://cloud.ibm.com/docs/cli?topic=cli-kubernetes-service-cliworker_pool_taint) at the worker pool level so that the replacement worker node gets these attributes.
* Automatic rebalancing: A replacement worker node is not created if the worker pool does not have [automatic rebalancing enabled](https://cloud.ibm.com/docs/containers?topic=containers-auto-rebalance-off).



Before you begin, make sure that your cluster has enough other worker nodes so that your pods can be rescheduled and continue to run.



1. List all worker nodes in your cluster and note the name of the worker node that you want to replace.

kubectl get nodes

The name that is returned in this command is the private IP address that is assigned to your worker node. You can find more information about your worker node when you run the ibmcloud ks worker ls --cluster <cluster_name_or_ID> command and look for the worker node with the same Private IP address.
2. Replace the worker node. As part of the replace process, the pods that run on the worker node are drained and rescheduled onto remaining worker nodes in the cluster. The worker node is also cordoned, or marked as unavailable for future pod scheduling. Use the worker node ID that is returned from the ibmcloud ks worker ls --cluster <cluster_name_or_ID> command.

ibmcloud ks worker replace --cluster <cluster_name_or_ID> --worker <worker_node_ID>
3. Verify that the worker node is replaced.

ibmcloud ks worker ls --cluster <cluster_name_or_ID>



ibmcloud ks worker replace --cluster CLUSTER_NAME_OR_ID --worker WORKER_ID [--update] [-f] [-q]
