An administrator notices that the clustered Data ONTAP 8.2.3 controllers are less responsive than normal. You use OnCommand Performance Manager but do not see obvious problems, yet, this particular issue is constant. Users are starting to complain.
Which tool would you use to collect data to help diagnose this issue?
Perfstat is a tool specifically designed for collecting performance data from clustered Data ONTAP systems. It gathers detailed performance metrics that are essential for diagnosing issues related to system responsiveness. This makes it the most appropriate tool in this scenario where OnCommand Performance Manager has not identified the problem and users are experiencing constant performance issues.
You are creating a disk-partitioned root aggregate.
Which two rules are enforced automatically when accomplishing this task? (Choose two.)
When creating a disk-partitioned root aggregate, two key rules are automatically enforced. First, a RAID group cannot have more than one partition from the same disk. This ensures redundancy and fault tolerance by spreading data and parity across multiple physical disks. Second, the only supported RAID type for aggregates containing root-data partitioned disks is RAID-DP. RAID-DP provides double-parity protection, which is crucial for maintaining data integrity in the event of multiple disk failures.
You receive the AutoSupport message, "CONTROLLER TAKEOVER COMPLETE PANIC" from a FAS3250 controller. You suspect a hardware issue. A core file was written to disk.
In this scenario, which two actions would you perform to obtain more information? (Choose two.)
To obtain more information about the hardware issue, you should collect the core file and upload it to NetApp Global Services (NGS) for analysis, as this will provide expert insights into the cause of the panic. Additionally, booting the failed controller to maintenance mode and executing the sldiag command will run diagnostic tests to verify the hardware status and identify any potential issues. These two actions will give a comprehensive understanding of the problem, enabling appropriate steps to be taken.
A customer cannot create a new volume from OnCommand System Manager.
Which two clustered Data ONTAP daemons would be at fault in this scenario? (Choose two.)
When a customer cannot create a new volume from OnCommand System Manager, the two clustered Data ONTAP daemons that could be at fault are typically mgwd and vldb. Mgwd (Management Gateway Daemon) is responsible for management operations, and vldb (Volume Location Database) is crucial for volume location and management. Issues with mgwd can prevent the GUI from working effectively, while issues with vldb can prevent volume operations, including creation, from functioning correctly.
You have a 6-node cluster with six identical controllers. You are upgrading from clustered Data ONTAP 8.3.1 to clustered Data ONTAP 8.3.2. From the Upgrade
Advisor, you downloaded the upgrade plan.
In this scenario, which two steps are part of that plan? (Choose two.)
When upgrading from clustered Data ONTAP 8.3.1 to 8.3.2, it is essential to set the new image as the default image to ensure that the nodes will boot from the new software version. Verifying system health is a crucial step before an upgrade to ensure that the cluster is stable and can handle the upgrade process. Migrating all aggregates to an HA pair, as mentioned in option C, is not typically part of the upgrade process. Performing a LIF migration for SAN LIFs before takeover is not required since SAN LIFs cannot be migrated.
