Good day, I'm working as a consultant and my customer often asks me about creating restricted roles. It would be useful to have a full list of exixting cmddirnames, at lest to verify AI suggestions vs allucinations 😀 I know that it could be verified by using the cli, issuing incomplete commands and showing suggestions with TAB key. But the customer does not allow me to use the CLI with a role that can create other roles 🙄 Also a "ontap emulator" could be great. Any suggestions are welcome. Thanks in advance.   Alessandro ...

FAS2750 device, system ONTAP9.16. When controller A node 1 took over controller B node 2, I started the system of node 2 and entered the menu mode to select the fourth option to clear the configuration. During the restart process, there was a waiting for giveback. Then I returned the configuration in node 1 and entered a brand new node system (node 3). In node 1, I recreated the cluster and allowed node 3 to rejoin the cluster. The configuration of cluster IP, node IP, interface lif, vserver, etc. before node 2 is still in place. I want to remove the failed node 2, but the prerequisite is to delete or migrate the vserver lif and other configurations related to node 2. However, I tried modifying the cluster IP, node IP, interface lif, and so on, which showed Error: command failed: RPC: Could't make connection [from mgwd on node] "FAS2750-03" (VSID: -1) to vifmgr at 169.254.157.6]， I use commands FAS2750::*> cluster remove-node -node FAS2750-02 -force true Warning: This command will forcibly remove node "FAS2750-02" from the cluster. You must remove the failover partner as well. This will permanently remove from the cluster volumes that remain on that node and logical interfaces with that node as the home-node. Contact support for additional guidance. Do you want to continue? {y|n}: y [Job 1064] Cleaning cluster database Error: command failed: [Job 1064] Job failed: Failed to delete SAN configuration for lif with id 1032 from its current node (FAS2750-02):No nodes are available to process the command. Verify that all nodes are healthy using the "cluster show" command, then try the command again. And the system alarm displays: FAS2750::*> system he al show Node: FAS2750-01 Alert ID: ClusterSwitchlessConfig_Alert Resource: FAS2750 Severity: Major Indication Time: Wed May 13 16:39:20 2026 Suppress: false Acknowledge: false Probable Cause: No cluster switch is detected and the switchless option is not enabled. Possible Effect: Communication problems and cluster connectivity issues occur. Corrective Actions: 1) If the cluster network is configured as a two-node switchless cluster (TNSC), enable switchless detection by using the "network options detect-switchless-cluster modify -enabled true" command. No further action is required. 2) If the cluster network is configured with cluster switches, the nodes fail to detect the switches. Ensure that the network interfaces on the cluster switches connected to the node cluster ports are enabled on both sides. If the errors are corrected, stop. No further action is required. Otherwise, continue to step 3. 3) Check the physical connections between the nodes and the cluster switches. Replace network cables with known-good cables. If the errors are corrected, stop. No further action is required. Otherwise, continue to step 4. 4) Ensure that either CDP (for Cisco switches) or ISDP (for NetApp CN1610 and Broadcom BES-53248 switches) is enabled on the cluster switches. FAS2750::*> network options detect-switchless-cluster show Enable Switchless Cluster Detection: true   Big shots, please help me take a look and answer my questions. Thank you very much. ...

We have been using snapdiff backups for our SVMs for years. We use IBM Storage Protect (latest version) and Data ONTAP 9.13.1.P7. The following messages keep appearing in the audit log of our cluster: 'Unable to find API: vfiler-list-info on data vserver SVM_xxx'. The message always appears when the backup of a filer volume starts. When we search for the error, we only ever find very old references to 7-mode. Is there a way to deactivate the message under ONTAP? ... View more

According to below link, SnapCenter is not supported on SnapMirror Sync. https://docs.netapp.com/us-en/ontap/data-protection/snapmirror-synchronous-disaster-recovery-basics-concept.html#   According to below, there is pre-defined SnapMirror policy SnapCenterSync which is supported on SnapMirrorSync. https://docs.netapp.com/us-en/ontap/data-protection/default-protection-policies-concept.html I am confused. Does that mean if I use SnapCenterSync will lose RPO=0 ? Any one can help me on this product compatibility. Thanks so much   Chun Chiang ... View more
