Postupgrade verification Use this procedure to perform a postupgrade verification. Before you begin Ensure that the upgrade to CloudLink 7.0 completed successfully. Procedure After the CloudLink Center upgrade completes, verify that all virtual machines are connected and stable in CloudLink Center. CloudLink Agents on connected machines attempt to connect to CloudLink Center after the upgrade is complete. If a machine is in a machine group that uses the Auto upgrade policy, the CloudLink Agent that is installed on that machine is automatically upgraded to version 7.0. If a machine is in a machine group that uses the Manual upgrade policy, you must manually upgrade the Agent. See Upgrade CloudLink Agents manually. Verify that all keystores are accessible by CloudLink Center. On all Windows VMs, verify that CloudLink Agent is connected to CloudLink Center and running version 7.0. On all Linux virtual machines, verify that: Use the svm about command to verify that the CloudLink Agent version appears as “Version 7.0.xxxx”. Use the svm status command to verify the volume encryption type is listed as dmcrypt. ecryptfs or LUKS volume types (in the third column) are legacy Linux formats that were used by CloudLink version 5.0 and earlier and they are no longer supported. It is recommended that you contact Dell EMC support to decrypt the ecryptfs or LUKS volumes and encrypt them with dmcrypt. NOTE: Key rotation is not available for the ecryptfs volumes until they are decrypted and reencrypted. In CloudLink Center, check if these alarms were raised after the upgrade: Alarm: Backup file wasn’t downloaded/uploaded to store recently If the alarm was raised, download a backup of the new CloudLink 7.0 system. Alarm: Vault unlock codes are not configured If the alarm was raised, set the CloudLink Vault passcodes as described in the Dell EMC CloudLink Administration Guide. Alarm: Key inaccessible If the alarm was raised, check the alarm for details. If you changed the CloudLink Vault unlock mode from Manual Unlock to Auto Unlock before the upgrade, change it back to Manual Unlock. For more information, see Change CloudLink Vault unlock modes. Restart the virtual machines to ensure that their boot processes are unaffected by the upgrade.
