Hi All I've got two NetApp clusters. "ClusterA" and "ClusterB". Both are running ONTAP 9.11.1P10. "ClusterA" has an SVM that contains a volume that has thousands of Shares attached to it (Which is also around 15TB in size). We are planning on Decommissioning "ClusterA" but before we do that we need to move the data over to "ClusterB". What is the best, easiest and safest / most reliable method for us to do this? We need to migrate the SVM from ClusterA to ClusterB but also keep everything in the exact same state. Is there a way? Just to also mention (i'm not sure if this matters), there is a cluster peer between both clusters. Thanks

Hi all, we are designing an archiving workflow and we’d like to get your advice on the best practices from the NetApp perspective. Our source is a NetApp ONTAP cluster with SnapLock volumes (WORM). The target is a remote LTO tape library (WORM media) managed by Commvault. The goal is long-term retention (10+ years). From an ONTAP performance and stability standpoint, does it make sense to use a staging disk for the initial backup and then move it to tape, or have you seen better results with other workflows? Also, considering the data is immutable, would you recommend a "Clean Archive" approach to minimize reads from the SnapLock volumes, or are there benefits to periodic full reads for data integrity checks? Any insights would be greatly appreciated!

Hello and sorry for my english, When i am on ONTAP GUI, it ask for updat disk firmware : An update is available for Disk FW revision NA03 for disk model X387_WPSCE16TA07. An update is available for Disk FW revision NA03 for disk model X388_WPSCE16TA07. i can dismiss, update, schedule. If i update, i can have trouble in production ? second little question, it is neccessary to install last disk bundle after that or not ? i can have trouble when i install disk bundle ? thanks

Hi Community members, Need your valuable suggestion as always. I have a 10 node cluster which is highly utilized all times. Among those 2 nodes are hitting 80% on regular basis. As this a critical cluster I am unable to set a maintenance window for ONTAP upgrade. Vol move activity are not possible at the moment as need to upgrade cluster by next week. Any valuable suggestions please let me how to proceed with maintenance window. Is there any critical parameter like IOPs, latency which I can look into for performance and decide to set maintenance window. It should be non disruptive upgrade and Host team should not have any downtime during the activity. ONTAP Version upgrade planned from 9.11.1p8 to 9.11.1p16 to 9.15.1p16,it is a multi hop upgrade.

If we are planning to perform ONTAP code version from 9.11.1P6 to 9.15.1P16 for 10 node cluster please help what prechecks need to be taken care for upgrade readiness. Few points already validated: 1.Upgrade advisor shows incompatible switch is with target ONTAP. 2. Validated intercluster switch version current NXOS version is 9.3.5 so upgrade to NXOS 9.3.14. Current RCF is at 1.8 and is compatible with target ONTAP 9.15.1P16. 3. Validate current sp firmware and check whether current SP version is compatible with target ONTAP code version 9.15.1P16 but in SP compatability matrix not able to find 9.15.1P16 version to validate SP version compatibility. If upgrade is needed, Need to perform SP upgrade before ONTAP upgrade. 4.Upgrade path from 9.11.1P6 --> 9.11.1P16 --> 9.15.1P16 9.11.1P16 (this hop is for PANIC: page fault (supervisor read data, page not present) on VA 0x20 in process mlogd) --> Post 9.11.1P16 ONTAP perform bootarg disable to remediate pre check block Initialization of network interface failed on X91440A --> 9.15.1p16. is this a suggested path. 5.Most of the times Nodes are highly utilized(CPU crossing 50%). and Weekend we notice node utilization is stable below 50% for only 2 hours, whether we are can prefer to go with this 2 hours for ONTAP upgrade as it is a 10 node cluster. 6. Post ONTAP upgrade of 9.15.1P16 perform disk firmware, disk shelf and DQP upgrade. 7. Is the upgrade sequence correct: Intercluster switch upgrade - sp firmware - ONTAP upgrade - disk upgrade - disk shelf -DQP upgrade. In addition to above points is there any additional checks/ground rules or requirements needed to perform ONTAP upgrade. And also advise on revert process whether it is disruptive. Any help is very much appreciated!!!!!
