Configuring SAN initiator groups from the CLI with Description

November 2, 2024, 6:16 pm
$
0
0

So from the WEB UI --> HOSTS --> expand --> SAN initiator groups

click +Add

NAME:

STORAGE VM:

HOST OPERATING SYSTEM: vmware

 

(check) Host initiators

 

enter Name:  11:22:33:44:55:66:77:88

enter Description: host-n1

 

FROM THE CLI:

lun igroup create -vserver SVN -igroup VMware-SVN -protocol mixed -ostype vmware -initiator  11:22:33:44:55:66:77:88

 

if you have multiple initiators it looks like this:

lun igroup create -vserver SVN -igroup VMware-SVN -protocol mixed -ostype vmware -initiator  11:22:33:44:55:66:77:88,11:22:33:44:55:66:77:99,...

 

ISSUE: how do I add a description for each Initiator assuming first two Initiators are for host-n1, next 2 are host-n2 since each initiator has two hba controllers.

 

Also from the WEB UI it shows connection status how can I from the CLI show the Initiators Connection status.

I want to use the ONTAP PowerShell Toolkit to get a tamperproof-snapshot

November 4, 2024, 11:11 pm

Hello.

Currently, I am doing a periodic snapshot with a Powershell script using the following command:
>New-NcSnapshot $netapp_volume_name $netapp_newsnap_name

 

In the settings of each volume, I think that snaplock will be enabled from the next snapshot acquisition by setting snapshot-locking-enabled to TRUE, but the command "New-NcSnapshot" in the Powershell toolkit does not have the option to specify the retention period.
In other words, we believe that the only way to execute a snapshot is to execute it without specifying the retention period.
In this case, is it correct to assume that the retention period of the SnapLock Retention Period set for the volume will be adopted?

Is there a difference in behavior when taking snapshots with the Powershell Toolkit?

 

* This question uses Google Translate, so there is a possibility that the sentence is wrong.

hello and sorry for my english,

 

I have Vmware hypervisor connect to my cluster in ISCSI. So, VM disks are store on Netapp cluster.

On my files volumes, Antiransomware is activate but not on Vmware volumes.

Do you think it is a bad or good idea to activate antiransomware on volumes where Vwmare disks are store ?

 

thanks a lot

quota

Hello:
I plan to use the snapmirror for data migration. Because a quota is configured on the source end, I plan to configure a volume quota on the destination end after the snapmirror is transferred and disconnected. Will the quota be the same as that on the source end?
For example, on the source end, I limit the size of a user to 100GB, and the user has used 50GB
I re-configure quotas on the destination end after the migration to check whether the quotas will be re-restricted

The takeover cannot be initiated because the storage failover is disabled.

November 11, 2024, 7:47 am

Apologies if I get the terminology all wrong. I've got two netapp filers configured as a cluster. It's ancient hardware, I migrated most of the servers hosted on there in Azure so we didn't bother renewing the support contract. One of the disks died a while ago but we had a spare which kicked in. And it ran without redundancy. As luck would have it, just before the migration project was finished another disk died and that bought down everything. I'm assuming the disk dying bought it down, and that no other hardware has failed. I would have thought the 2nd cluster would have taken over but it didn't.

The status on the node says;

The takeover cannot be initiated because the storage failover is disabled.

 

Mashk_0-1731339999210.png

 

I'm guessing that because the disk died in the 1st node, that bought it down. So I thought if I replaced the disk then assigned it to the downed node it would come into life. However, I can only assign the unsigned disk to the node it can see. I can't get to node 1 at all

So, I think my only option is to try and force the failover mode to the 2nd node in the cluster.


FASCLUS1::> cf status
Takeover
Node Partner Possible State Description
-------------- -------------- -------- -------------------------------------
FASCLUS1-01 ARBFASCLUS1-02 - Unknown
FASCLUS1-02 ARBFASCLUS1-01 false Waiting for FASCLUS1-01, Takeover
is not possible: Partner node halted
after disabling takeover


I think my only option would be to run cf forcetakeover from 02 node.

 

Is this a good idea? Anything else I can try?

How to determine if files are ransomware

We are on ONTAP version 9.14.1P8, after we enabled the anti-ransomware on CIFS volumes, we started receiving suspected long  file list every day, we know they should be non-ransomware related. My questions is how we can safely determine they can be skipped. Are there any generic rules or utilities we can use for this purpose?

 

Otherwise nobody wants to set the files as false positive. 

Please share your experience if any.

thanks in advance !

Is there any way to create a Cluster Admin login\ role which limits access to specific SVMs only? I would prefer not to have to create multiple configurations on multiple SVMs as the admin overhead would be substantial for both myself as the Cluster admin the the SVMs administrators who would need to perform multiple logons.

resizing volume via powershell module command started to fail after ontap upgrades

November 21, 2024, 7:42 am

Hi, after an ontap upgrade we are now getting a cryptic message to me and I can no longer use the code to resize volumes. The help file for this command is not super detailing and it doesn't matter if I try to grow 1mb or one tb  and it happens on any volume for any svm across 3 filers.

 

here is the command that now fails and the error it throws 

 

Set-NcVolSize -Name $vol2.Name -Size +1tb -VserverContext:$vol2.Vserver
Set-NcVolSize : One or more of the fields "-max-autosize","-size" are being set/modified. Set the values such that "-max-autosize" and "-size" should always be less than or equal to 600.

+ CategoryInfo : InvalidOperation: ({nccluster]:NcController) [Set-NcVolSize], EAPIERROR
+ FullyQualifiedErrorId : ApiException,DataONTAP.C.PowerShell.SDK.Cmdlets.Volume.SetNcVolSize

 

the 600 stays constant across any volume  or any filer 

 

any one know how to debug this further or know the answer to why this used to work and stopped after the code upgrades?

FabricPool disaster recovery

November 22, 2024, 6:46 am

My production cluster consists of an AFF-A400 HA pair and a FAS-8300 HA Pair running 9.13. I want to configure FabricPool to tier cold data from the A400 to the 8300. My understanding of how FabricPool works is that the actual data will be relocated to the S3 bucket on the 8300, but the metadata remains on the A400. This has me wondering how best to protect this data from a disaster.

 

I have another FAS-8300 HA pair at a remote data center. I assume I need to snapmirror both the FlexGroup vols on the A400 that are hosting the hot data and the FlexGroup vol on the 8300 that is hosting the S3 bucket. Is this correct? In the event that I had to fail over to my remote 8300, how would I bring the FabricPool data online?
