Hidden Gems – NetApp Operations Manager Storage Efficiency Dashboard Plugin

17 Saturday Aug 2013

NetApp

This is a relatively unknown plugin for DFM/Operations Manager, now called OnCommand Unified Manager. The Plugin helps to answer a number of questions related to storage utilization and storage efficiency savings.  It also helps in identifying ways to improve the storage utilization.  It is implemented as a script that can be installed on the Operations Manager server.   The script can be scheduled for execution in Operations Manager and generates a set of web pages that provide an Efficiency Dashboard for the NetApp storage systems managed by Operations Manager.  Two primary charts are produced with additional charts to provide detailed breakdowns of how the storage space is being consumed.  These charts can be produced to represent all storage systems being monitored by Operations Manager, ‘groups’ of storage systems as grouped in Operations Manager or a single storage system. I wonder why they don’t include this as a tab inside OnCommand Unified Manager by default.

Note: click images to see a larger version.

Download it from here:
http://support.netapp.com/NOW/download/tools/omsed_plugin/

1) To install from the OnCommand Unified Manager browser interface:

a) Login to Operations Manager as an administrator. Click Management > Scripts.
storageeffplugin5.2-1

b) On the Scripts page choose the option to select the omeff_oc52_windows64.zip file you downloaded above and click Add Script.storageeffplugin-5.2-2

c) On the Confirm page, read the summary and click Add.storageeffplugin-5.2-3

d) After the script is installed, in the lower section, select the script check box and click “No” under the Schedule column.storageeffplugin-5.2-4

e) On the add a schedule page, enter a name for the plugin such as Storage Efficiency Plugin and at the bottom, enter the schedule of your choice. I run it daily at 05:00 AM. Click Add Schedule when done and you should see the schedule you chose.

storageeffplugin-5.2-6

2) If you want to install from the the OnCommand Unified Manager CLI:

C:\Program Files\NetApp\DataFabric Manager\DFM\bin\dfm script add omeff_oc52_windows64.zip

3) Access the Dashboard. After the script has run the first time, the dashboard will be available. Its located at the root on your OnCommand URL. Just add /dashboard.html at the end as shown in the example below.

New Releases: NetApp Data ONTAP Powershell Toolkit 3.0 and OnCommand Systems Manager 3.0

NetApp

1) Data ONTAP PowerShell Toolkit v3 (access with free community site account)
https://communities.netapp.com/docs/DOC-22259

The new version adds support for clustered ONTAP 8.2 with 67 new cmdlets.

2) OnCommand Systems Manager v3 (you need a support contract to download)
http://support.netapp.com/NOW/download/software/systemmgr_win/3.0/

Of particular note if you still have DOT7 systems:
The installer installs both System Manager 3.0 and System Manager 2.2.0.1. System Manager 3.0 enables you to manage clustered Data ONTAP systems and System Manager 2.2.0.1 enables you to manage 7-Mode systems. System Manager 2.2.0.1 supports all the features, enhancements, and changes in the System Manager 2.2 release.

System Manager 3.0 is launched in a new browser tab or window if you are managing clustered Data ONTAP systems. Similarly, System Manager 2.2.0.1 is launched in a new browser tab or window if you are managing 7-Mode systems.

Hidden Gems – Health check Network, ONTAP, NAS and SAN configuration on NetApp storage within the NetApp Management Console

I believe this feature has been around since the DFM v4.x releases. If you haven’t noticed, DFM has been re-branded to NetApp OnCommand Unified Manager. There are Core and Host packages. You can download the latest v5.2 release here. You need a support contract to access the site.

Note- click images in the post below to increase size.

The NetApp OnCommand Unified Manager Core package bundles a great performance analysis tool built into the NetApp Management Console. Once you install OnCommand Unified Manager Core, its available in two locations:

1) C:\Program Files\NetApp\DataFabric Manager\DFM\web\clients\nmconsole-setup-3-3-win32.exe.

2) Start > NetApp > DataFabric Manager > Show Appliance Summary Page > click Setup > click Download Management Console.

nmc-1

2a) Click Download Windows Installation (version 3.3) and save it locally.

nmc-2

Install the Management Console on your workstation or server.

1) Double-click nmconsole-setup-3-3-win32.exe > Next > Install > Next > Finish. It will launch when done.

2) Enter your OnCommand Unified Manager server name or IP, username and password and click connect. Note you can click Options and switch between http and https. Hopefully you are using https.

nmc-3

3) In the upper left, click Tasks > Manage Performance. Under View, select Logical and click the controller that you want to assess.

nmc-5

4) In a few seconds the page will render. On the right, just above the Network Throughput diagnostic panel, click View Actions > Diagnostics.

nmc-8

5) You will see either green, yellow or red as indicators of the health check category. Click on each and see what is available. In this case, when you select NAS Specific Issues, it says that Atime updates are enabled on the volumes. See the recommendation at the bottom and correct as needed.

nmc6

Note: You can sometimes improve performance by directing Data ONTAP to skip logging of access time (atime) information to NVRAM. The downside is that if there is a storage system crash, a few seconds worth of access time updates may not be recorded in the file system.

To make the change:

> vol options <your_vol_name> no_atime_update on

6) In this image for SAN Specific Issues, you can see it has detected LUN partial read/write issues. Assess the recommendations and make changes as needed.

Note: notice on the left that you can adjust the date and time of the diagnostic. This is useful when you want to assess a change you made to an NFS mount, for example rsize=8192,wsize=8192, or maybe a realigned LUN, etc. You can go back in time and correlate the diagnostic and performance data.

nmc-7

7) See TR-4090 (page 46) for Diagnostic tests and meanings.

Using pathping.exe on Windows to find latency in your network

You suspect your network is burping because your storage replication is slow or failing, or maybe your CIFS shares have inconsistent write errors or disconnects, or you just think the network is slow as molasses. Before calling your network team and waking them from their post lunch nap, try to pinpoint the issue with pathping.exe. It has been there since Windows XP and is a little known utility.

Pathping.exe provides information about network latency and network loss at intermediate hops between a source and destination. Pathping sends multiple Echo Request messages to each router between a source and destination over a period of time and then computes results based on the packets returned from each router. Because pathping displays the degree of packet loss at any given router or link, you can determine which routers or subnets might be having network problems. Pathping performs the equivalent of the tracert command by identifying which routers are on the path. It then sends pings periodically to all of the routers over a specified time period and computes statistics based on the number returned from each.

Example:

C:\Users\me>pathping -n 212.58.251.195

Tracing route to 212.58.251.195 over a maximum of 30 hops

Trace complete.

You can clearly see that between hops 9 and 10 (in red above) the RTT (round trip time) jumps to 93 milliseconds with 8% packet loss. Bingo. Point your network person to this router.
