Snapmirror throttle
Hi there,
does anyone have an Idea to schedule the global Snapmirror throttling?
Maybe one of us created a Powershell Template?
Thanks for help!

Unwanted system messages every day
We get every day four messages from our FAS2520. The message are: callhome.management.log: Call home for MANAGEMENT_LOG.
In the last week we want to deactivate this messages with this parameter:
'system node autosupport modify -node NA252011 -noteto "" '
The result was:
FAS25201::> system node autosupport modify -node NA252011 -noteto ""
FAS25201::> system node autosupport modify -node NA252012 -noteto ""
FAS25201::> system node autosupport show -node * -fields noteto,to node to noteto
-------- -- ------
NA252011 - -
NA252012 - -
2 entries were displayed.
But we get the 'callhome.management' message again and again every day, only from this system. We compared the settings on the system with the settings on the other systems, everything is the same. We do not receive these messages from the other systems.
Is there still a way to turn off the messages?We have the problem with all ONTAP versions, currently we use ONTAP 9.3P6.

Re: 7MTT Access not possible after installation
The problem is unfortunately still existing in the 2018 release (7MTT 3.3.1).
With the german language package I tried Windows Server 2012 and 2008 without success (the 7MTT service stopped immedeately after starting it). Only to switch completely to english language pack (as described from skellner) worked for us.
This makes it hard to use the tool in germany, as most customers use german version!!

Re: Unwanted system messages every day
Hi
look for a fields called "partner-address" and "support-address".
noteto is the one you do want to use. as it will only send alerts

Re: Unwanted system messages every day
Hi Gidi,
the command 'system node autosupport show -node * -instance' shows the following:
...
List of To Addresses: -
(DEPRECATED) List of Noteto Addresses: sanadmin@stadtdo.de
List of Partner Addresses: -
...
Support Address: autosupport@netapp.com
...
Is there another way to set up mailboxes to receive support messages?

Re: Disks sanitize
Hi Chris,
What command we need to use to perform the Disk Santize from SP login ?
Thanks ,
Manik.

Re: Disks sanitize
You need to boot or setup then boot ONTAP to sanitize disks. The exact specifics depend on the model and ONTAP version present on the system

FAS2552 ports
Hi all,
I have a 7-mode FAS2552 which is connected to 2 FC switches from its ports e0c and e0d, both controllers.
Can the other two ports on each controller (e0e and e0f) also be connected to the Fiber Switches for redundancy or even better speed?
Thanks in advance!
↧
Re: FAS2552 ports
e0c and e0d are LAN ports, you probably mean 0c and 0d. Yes, two other ports can be used either as LAN or FC. You will need to use matching SFP and possible reconfigure port mode (switch between LAN and FC).

OnTAP Upgrade Alert: OpenSSH 7.2 Upgrade Violation
I upgraded OnTAP from 8.2P4 to 8.3P7 on our DR cluster yesterday, via the System Manager Cluster Upgrade GUI. When performing validation, I received the following alert:
--------------------------------------------------------------------------------------------------------------------
"hmac-ripemd160" and "hmac-rivemd160-etm" are considered weak keyed-hash message authentication code (HMAC) algorithms and support for the same will be removed after upgrading to Data OnTAP 9.3.
Advice:
Ensure the Vservers do not have these HMAC algorithms configured before attempting to upgrade.
Action:
Before retrying the upgrade, remove the above weak algorithms using "security ssh remove" command. To list all Vservers configured with one or both the above HMAC algorithms, run "security ssh show -mac-algorithms hmac-ripemd160* -vserver * -fields vserver" .
--------------------------------------------------------------------------------------------------------------------
I tried the "security ssh remove" command, however when I chose "hmac-ripemd160" for an SVM it removed ALL algorithms for that SVM. I used "security ssh add" to add it back, and all algorithms came back.
I wasn't too concerned about this for our DR cluster, so I went ahead with the upgrade and everything was fine. Sure enough, the offending algorithms were removed automatically without any effort on my part.
Next week I plan to upgrade our production cluster and want to ensure this will not be an issue. I always do prod at the command line so I likely wouldn't have even seen this message had I not done DR from the GUI (this message doesn't appear in Config Advisor or the Upgrade Guide). Is there any way to determine if a particular alorithm is actually in use? I would suspect not but know of no way to verify. Would love to hear any thoughts or recommendations!

Re: Snapshot in use, and cannot delete
There is no way that you can delete that busy snapshot. you can't force or ignore-owner.
Please try these steps. It works like a charm:
1. create new snapshot on the source cluster, label the snapshot properly so that the snapshot will be used for snapmirror
2. on the destination cluster, re-create the snapmirror job.
3. on the destinaiton cluster, run "snapmirror resync". it will use the newly created snapshot for snapmirror and release the busy snapshot that you try to delete.
4. delete the "busy" snapshot (which is not busy anymore) on the destination volume.

Re: FAS2552 ports
Hi and thanks for your reply.
You are right, I do mean the ports 0c and 0d.
I want to use them as FC ports for redundancy and maybee better transfer rates,
but when I insert an SFP I receive the error message "The SFP in adapter 0e is not valid... adapter supports 10 Gbit/Sec
but inserted SFP supports 4, 8, 16 Gbit/sec"
Do I have to reconfigure the ports 0c and 0d?
In the GUI I see them configured as FC ports (see attached image)
↧
Re: FAS2552 ports
You'll probalby need to flip the mode from CNA to FC on the port.
Can you post the output from
ucadmin show
