Error run into while backing up AHV virtual machines
The following table describes the problem that might occur when you back up AHV virtual machines:
Table: Error while backing up AHV virtual machines
Error message or cause | Explanation and recommended action |
|---|---|
After a NetBackup backup operation, the VM snapshot on the AHV cluster is not deleted. | If a disk attached to the VM is in an inactive state, then the AHV cluster does not delete the VM snapshot after a backup operation is complete. Workaround:
|
MSiSCSI service is disabled. Enable the MSiSCSI service on the backup host. | Enable Microsoft iSCSI Initiator Service (MSiSCSI) service on the windows backup host and re-run the job. |
Unable to establish a connection. Verify that the iSCSI service is installed and running. |
|
Authentication failed. Verify whether the provided initiator CHAP is correct. | Either the provided CHAP key is invalid or the iSCSI initiator name is not unique for each backup/recovery host. Please set iSCSI initiator name unique for each backup/recovery host. |
Failed to get an external data service IP address for iSCSI. Re-run the job after setting IP address on the Nutanix cluster: {Nutanix AHV clusterName}. | Set the external data service IP address for iSCSI on the Nutanix AHV cluster. More details See Configure Nutanix AHV cluster. Note: For Linux it will fall back to use the NFS for backup/restore. |
NetBackup version is not supported for one or more backup hosts. Use NetBackup version 9.1 or later on all Linux or Windows backup host to use the Automatic backup host option in Nutanix protection plan. | This error occurs when the Automatic option is selected for backup hosts in the Nutanix protection plan. Upgrade backup host to latest NetBackup version. |
For NetBackup media server load balancing, ensure that the backup hosts have either Red Hat Enterprise Linux, SUSE Linux Enterprise Server or Microsoft Windows operating system. | This error occurs when the Automatic option is selected for backup hosts in the Nutanix protection plan. For Nutanix AHV, supported media server are:
|
Existing version of NetBackup on the media server does not support the incremental backup schedule. | Upgrade NetBackup to the latest version on the backup host. |
Unable to set resource limit for specific Nutanix clusters. | If the clusters for which the resource limit is set are deleted from NetBackup environment, in some cases, + Add option is disabled to set the resource limit. Recommended Action Delete the resource limit for deleted clusters and then set the resource limit for rest of the clusters. |
Snapshot jobs fail with error code 156 with the following job details: Critical bpbrm (pid=30139) from client 9c5dcb07-65d2 -4761-b861-9e517edcf5b6_ <Nutanix-cluster> vxindia.veritas.com: FTL - Value 2 that specifies GUID is not supported for the nameuse | If a protection plan is created using Backup option > Select server or host to use for backups > Automatic and the selected storage unit is configured with media servers with both NetBackup 9.1 or prior versions. And when this protection plan is used to back up the AHV VMs or Intelligent VM group, the snapshot job might fail. Recommended action All the media servers, which are configured in the selected storage unit, must be upgraded to NetBackup 9.1. To avoid job failures as upgrades for other media servers are in progress, in the Protection > Customize Protection > Backup options option, manually select a specific media server or backup host as a server or host to use for backups instead of default Automatic option. It is recommended to use already upgraded media server. Once upgrade of all media servers completes, use Protection > Restore Original Settings to go back to original settings. |
Error 1 iscsiadm: Could not login to [iface: default, target: iqn.2010-06.com.nutanix: nbubackup -2d29da9d-f964- 4157-9595-f0319090bb01-tgt0, portal: xx.xx.xx.xx,3260] iscsiadm: initiator reported error (24 - iSCSI login failed due to authorization failure) iscsiadm: Could not log into all portals Error 2 iscsiadm: Could not execute operation on all records: encountered iSCSI database failure Error 3 iscsiadm: could not read session targetname: 5 iscsiadm: could not find session info for session28 | These errors are seen in the successful job details tab of backup/restore jobs. These errors are output of iscsiadm command execution. These errors are intermittent and may occur due to heavy load on the iSCSI network. NetBackup does a retry operation to fix these errors. Once retry operation is successful, backup/restore job is also successful. Recommended action No action is required on NetBackup side. User can still troubleshoot the iscsiadm and ensure correct iSCSI installation/configuration to avoid such errors. |
