NetApp's All SAN Arrays (ASAs) allow for maximum file sizes of 128TB, compared to 16TB for other FAS and AFF systems running ONTAP. ASAs are all-flash SAN-only solutions based on AFF platforms and available starting with ONTAP 9.7. Documentation for AFF systems can also be used for the corresponding ASA system for cabling and other information.
Our 5 senses can only perceive representation of reality but not the actual r...Ashwin Pawar
?
Perceived reality exists within space and time, but actual reality is being discovered through quantum physics, though ancient sages in Asia have known it for thousands of years. Quantum theory shows particles can be in different states simultaneously, though humans can only perceive one state at a time as we move through time. Devotees of Indian gurus have demonstrated being in different states at once, documented for years but not widely accepted until quantum physics. Reaching this state requires going beyond the five senses and spending years in realization, as it is not something outside us but a matter of inner realization.
Consciousness is a constant that witnesses events and objects which are variables. One comes to know themselves by understanding what they are not through experiencing events which are a function of consciousness and objects. Experience is defined as consciousness plus an object that is witnessed by the constant of consciousness.
SnapDiff is NetApp's proprietary indexing engine that identifies file differences between two snapshots. It compares the base and diff snapshots using inode-walk and returns a list of added, deleted, modified, and renamed files. Backup software vendors can integrate their solutions with SnapDiff through its API to perform incremental backups using snapshots. SnapDiff provides faster indexing compared to traditional file system crawlers or NDMP backups by identifying file changes at the inode level rather than performing a full tree walk.
Oracle database might have problems with stale NFSv3 locks upon restartAshwin Pawar
?
The document discusses stale NFS locks that can occur upon Oracle database restart with NFSv3. The issue is caused by lockd and rpc.statd using different name resolution methods to create and clear locks, resulting in non-matching host names. The solution is to change the order of host names in /etc/hosts so the same host name is used for lock creation and clearance.
The document discusses an error when attempting to perform a SQL backup clone using SnapCenter 4.3 on a NetApp cDOT storage system using iSCSI. The error references SMB even though iSCSI was being used, because the SnapCenter storage connections were using the cluster management LIF instead of the data SVM management LIF, which is required for SAN protocols like iSCSI. The solution is to add the data SVM directly in SnapCenter using the SVM management LIF.
Network port administrative speed does not display correctly on NetApp storageAshwin Pawar
?
The document discusses a bug where the administrative speed of network ports on NetApp storage incorrectly displays as 1000 instead of 10000, even though the operational speed is 10000. This bug was fixed in ONTAP version 9.6RC1 and later. The writer observed this same issue on their FAS8200 running ONTAP 9.1, where the administrative speed of ports e0c and e0d both displayed as 1000 although the operational speed was 10000.
How to connect to NetApp FILER micro-USB console portAshwin Pawar
?
The document discusses how to connect to the console port of a NetApp Filer using a micro-USB cable and configure Putty serial terminal software. It explains that 115,200 baud rate with N-8-1 refers to transferring up to 115,200 bits per second with no parity, 8 data bits, and 1 stop bit. The steps are to connect the micro-USB cable from the Filer to a laptop, identify the detected COM port in the device manager, open Putty, select the correct COM port and baud rate settings, and click open under the session tab rather than the incorrect arrow shown.
Intercluster LIFs are preferred over data LIFs for NDMP control and data communication to ensure firewall access. If only data LIFs can be used, connection depends on the order interfaces appear in ifconfig output, not a hardcoded selection. More details are available at the provided KB article on properly configuring LIFs and firewall policies for NDMP backups.
How to use Active IQ tool to access filer informationAshwin Pawar
?
This document provides instructions for using NetApp's Active IQ tool to access various types of information about a FILER, including cable diagrams, stack diagrams, RAID configuration visualization, hardware capacity headroom, and storage summaries. Users can log into the NetApp support site, enter the FILER name, click on the Configuration button, and select Visualization to view diagrams and other data pulled from the last AutoSupport report. The Active IQ tool extracts valuable information from a FILER's AutoSupport reports with some patience during loading of dynamic visualizations and data.
A SAN provides block-level storage to clients that they can then use to build their own file systems, similar to a real estate provider giving a plot of land. A NAS provides a complete file system to clients similar to a real estate agent providing a ready-made home, with the NAS appearing as a file server and the SAN appearing as a raw disk to the client operating system. The key difference is that a SAN provides raw disks while a NAS provides a complete file system.
Steps to identify ONTAP latency related issuesAshwin Pawar
?
The document provides steps to identify and understand latency issues on a NetApp ONTAP system. It analyzes sysstat output showing CPU utilization across various domains. While overall CPU usage is high at 97%, no single domain is fully utilized, indicating CPU is not the root cause of latency. It recommends investigating service level latency for specific LUNs, volumes, or protocols. Using ONTAP QoS commands, it identifies disk latency of 3ms on one aggregate which is within normal limits and not likely the root cause. The aggregate is 89% full which is also not yet concerning given its flash composition.
SnapDiff is NetApp's proprietary file differencing engine that identifies files changed between snapshots. It compares block-level changes rather than traversing the entire file system, improving backup performance. The SnapDiff API allows backup applications to integrate with SnapDiff. SnapDiff performance is measured in files processed per hour and is impacted by very large or deeply nested directory structures rather than total storage size.
The SnapDiff process flowchart first takes a baseline backup snapshot of a volume. Next, it takes an incremental snapshot once it has the required information. It then begins the SnapDiff process to compare the snapshots and backup changed data.
The document discusses troubleshooting a SnapDiff performance issue. Key factors that can affect SnapDiff throughput include hardware resources, Data ONTAP version, disk I/O latency, number of files in volumes, parallel SnapDiff sessions, and overlapping backup jobs. Symptoms of timeouts between ONTAP and the media agent during the indexing phase suggest the indexing is taking too long. The document provides workarounds like skipping cataloging and running it later, and using live browse for restores if needed before investigation is complete.
Volume level restore fails with error transient snapshot copy is not supportedAshwin Pawar
?
A volume level restore failed with an error message indicating that a transient snapshot was not supported for the operation. The error occurred because the snapshot being used was a temporary one created during a SnapVault transfer where deduplication was enabled, making it an invalid snapshot. To resolve it, ensure the snapshot is a valid Snapmirror base snapshot without special characters in the name.
A predictive failure alert was reported for disk 1c.xx.xx in NetApp cluster node Cluster-02. The disk reported a predicted failure event. If a matching spare disk is available, rapid RAID recovery will begin by copying the data from the pre-failed disk to the spare. If no spares are available, the disk will eventually fail and cause the RAID group to degrade until a spare is available to reconstruct the data. Proactive assignment of a partner node's spare disk is recommended.
OCUM shows ONTAP cluster health degradedAshwin Pawar
?
The document discusses a degraded cluster health status shown in OCUM after adding a cDOT ONTAP controller. While the node pairing status was good, the cluster health showed as degraded. This was because OCUM only marks cluster health as OK after subsystem checks return OK, and one subsystem here showed as degraded, causing the overall cluster health to display as degraded. The solution is to ensure the cluster show and system health subsystem show both return OK.
NDMPCOPY lun from 7-mode NetApp to cDOTAshwin Pawar
?
The document describes how to copy archived SQL database LUNs from a 7-mode SnapVault snapshot to a cDOT SAN volume using NDMPCOPY in two phases. Phase 1 uses NDMPCOPY to transfer the LUN from the 7-mode snapshot to the cDOT destination volume. Phase 2 presents the copied LUN to the SQL box by mapping, rescaning disks, and bringing the LUN online so the databases can be retrieved.
This document discusses components that can contribute to latency in an IT infrastructure, with a focus on storage latency. It identifies potential sources of latency including applications, hosts, virtual machines, networks, and storage components. It recommends commands like 'qos statistics volume performance show' and tools like OCUM/OPM to analyze latency across clustered Data ONTAP components and identify bottlenecks. The document aims to help storage administrators troubleshoot latency issues by examining statistics from different parts of the infrastructure to pinpoint the root cause.
NVRAM is a separate DIMM from main memory, while NVMEM uses part of the main memory and is not a separate DIMM. The document provides examples of hardware showing NVRAM as a separate 4GB DIMM, while NVMEM on a filer uses 2.4GB of the total 20GB main memory. It clarifies the hardware difference between NVRAM using a separate DIMM and NVMEM utilizing space within main memory.
NFS and SANs can provide block-level access to storage in almost identical ways from the perspective of applications. At the protocol level, block reads over NFS and iSCSI are almost identical - they both request a number of bytes or blocks starting at a given offset. The main difference is that NFS uses file handles to identify blocks while SANs use LUNs, but a LUN and file are just containers for blocks of data. NetApp's WAFL file system allows it to present LUNs as files within aggregates, unifying SAN, NAS, and iSCSI storage into a single appliance by storing data at the block level regardless of protocol. Dave Hitz was instrumental in revolutionizing storage through his work
What is storage from client's perspectiveAshwin Pawar
?
This document defines storage from a client's perspective in 3 simple words: capacity, performance, and service quality. It explains that clients do not care about the technical details of the storage system, but rather care about getting the capacity and performance that was promised in a consistent manner by the service provider. The client's main concerns are how well their applications and databases run using the storage service.

The document summarizes an issue where one node of an HA pair could access the c$ or etc$ shares but the partner node could not. The cause was determined to be a registry setting on the filer's management interface that blocks data traffic, which was turned on for one node but off for the other. The solution is to set this option to 'off' on both nodes to allow access to the shares from either node.

Is it possible to upgrade or revert ontap versions on a Simulator
1. Is it possible to upgrade or revert ONTAP
versions on a Simulator, and why do you
want to do that?
Reason: With newly upgraded NetApp site, the NetApp Simulator tool's page maintains only
limited (latest 3 I guess) images of the Simulator. Therefore, if you have a requirement to
test a specific ONTAP version for a reported bug or for troubleshooting purpose or to test a
feature without being concern about breaking anything on Production Filers, then it makes
sense that you might need to do that.
Is it possible: Yes, you can either upgrade or revert a Simulator image.
