After upgrading my home lab infrastructure, I decided to change my IP schema from a 192.168.X.X to a 10.0.X.X

My hope was to avoid potential overlapping IP conflicts, when creating private VPN tunnels between sites; for SnapMirror projects. More on that later….

After successfully changing the IP addresses on my Ontap Select Cluster and the underlying LIFs, I noticed a mailbox error in System Manager, notifying me that I could no longer perform a takeover or giveback.

Remembering that I forgot to change the IP address on my Ontap Select Deploy (Mediator), which is a requirement to manage the HA of your 2-Node Ontap Select Cluster, I could not locate a way to modify the management IP.

After researching, I found out that you cannot just modify the existing Ontap Select Deploy VM, you need to create a Backup of the old Deploy VM and restore from backup to a new Deploy VM.

The Procedures are located in the NetApp Ontap Select Deployment Guide.

• Backup and Restore Deploy VM must be the same Version.
• The NEW Deploy VM must be in a blank state, just deploy the OVA and make no modifications.

Deploy Ontap Select OVA with NEW IP schema

How to create a Backup of your Ontap Select Deploy VM

• Create a backup of the existing Deploy

• Enter a password to encrypt the backup

• Retype the NEW password

• Backup Job Started

• Check on Backup Job

• Download Backup URL

How to Restore Ontap Select Backup to a NEW Deployed VM

• Copy Backup file to NEW Deploy VM using SFTP

• Restore the Backup in the NEW Deploy VM
  • ~deploy backup restore -filename hdcbackup.tar.gz -path /home/admin

• Enter the password to decrypt backup file.

• After the restore is successful, the Deploy VM will Reboot automatically

Reconfigure the Mailbox on Ontap Select Cluster

After deploying a NEW Ontap Select VM, and recovering from a backup, you still need some minor cleanup to bring the HA to a healthy status.

Since the IP address of the NEW Ontap Select Mediator is different, you will need to remove the old reference and add the new iscsi-targets.

• Login to the Ontap Cluster via CLI and enter Advanced Privilege Mode
  • ~set advanced

• The iscsi-targets are pointing to the IP address of the OLD Deploy
  • ~storage iscsi-target show
  • Take note of the Target Name, you will need this later

• Remove the OLD mediator iscsi-targets
  • ~storage iscsi-initiator remove-target -node * -target-type mailbox

• Add the NEW mediator iscsi-targets and reference the NEW Deploy IP address
• ~storage iscsi-initiator add-target -node <node1_name> -label mediator       -target-type mailbox -target-portal <ip_address> -target-name <iqn.target>

• Determine names of the mediator disks
  • ~disk show -container-type mediator

• Assign the Mailbox Disks to the two nodes in the Cluster
  • ~disk assign -disk NET-2.1 -owner HPENODE-01
  • ~disk assign -disk NET-2.1 -owner HPENODE-02

• Verify that storage failover is enable and HA is healthy
  • ~storage failover show
