CN1610 Serviceport DOWN

$
0
0

I have re-configured two CN1610 switches - erase config - and applied 1.2.0.7 and RCF 1.2.

Configured serviceport on both and only one of the switches is avaialble on the network.

 

SWITCH1

serviceport protocol none

serviceport ip 192.168.0.7 255.255.255.0 192.168.0.1

 

SWITCH2

serviceport protocol none

serviceport ip 192.168.0.8 255.255.255.0 192.168.0.1

 

SWITCH2 link light comes on when connected to the patch panel and I can access it via PuTTY


SWITCH1 however, does not light up and SHOW SERVICEPORT shows Interface Status Down

 

I can swap the network cables between the two switches and the problem stays on SWITCH1

 

It certainly appears to be a mis-configure of some sort on SWITCH1 itself.  What am I missing here?

 

 


Copying ONTAP images to Controller

$

I have a situation to do an image upgrade on a couple of nodes that's not in our network anymore. The only option is to connect to the console port, setup the cluster and upgrade the image. I already completed a boot option-4 (clean up) on both nodes. 

 

The challenge now is how to transfer the image from my laptop to the controllers using the http server on my laptop meaning that my laptop NIC should be able to talk to a port on the controllers (e0a, e0b, e0M etc). I can setup any of these ports on the controllers with an IP address (same subnet as my latop IP) during the initial cluster setup but I am wondering how to transfer the image to the controller using the http server when my only one laptop NIC is connected to the console port on the controller. Will I be able to get this job done using a small 4-port switch. 

 

I am not sure if my laptop NIC will be able to talk to the controller console port through this switch. It will be a great help if I could get an answer how to make all these  cable/port connections on to the 4-port swtich and to get the image upgrade done before I ship it out to another location.

Secure NFS help

I'm working on getting an NFS mount to succeed using krb5p security using a RHEL 7 client. Kerberos is enabled on a data lif of the SVM. The linux client has kerberos set up correctly to at least ssh in and get a kerberos ticket generated. I just can't figure out the piece I'm missing to get NFS mount with krb5. A successful kinit with a domain user account uses encryption type aes256-cts-hmac-sha1-96.

 

2 errors I'll make note of.

 

First is in the event logs of the NetApp, a secd error. Not sure why it's trying ArcFour when SVM is set to only allow aes-128, aes-256. krb.conf on client only set for aes256-cts-hmac-sha1-96

 

Message Name: secd.nfsAuth.problem
**[ 11] FAILURE: Failed to accept the context: Unspecified GSS failure. Minor code may provide more information (minor: Encryption type ArcFour with HMAC/md5 not permitted).
Corrective Action: Examine the failure details to determine corrective action. Common failures include name mapping issues, or the inability to communicate with domain controllers, NIS servers, or LDAP servers due to connectivity or configuration problems.
Description: This message occurs when an NFS authorization attempt fails.

 

Second error is on the linux client yet there is a SPN in AD and in the keytab file of the host for nfs.

 

gssproxy[553]: (OID: { 1 2 840 113554 1 2 2 }) Unspecified GSS failure. Minor code may provide more information, Client 'nfs/rhel7test.realm.example.com@REALM.EXAMPLE.COM' not found in Kerberos database

 

Also possibly related: The 'klist -ke' command shows many encryption types for each principle name listed. Where are all of these populated from when I only desire AES?

Backing up CIFS shares (currently using Unitrends) Options?

$
0
0

We have a FAS2552 that contains all our data and VM's.  The servers are about 1TB, and CIFS shares are about 9TB.  We are using a Unitrends appliance that is up for renewal, and is getting maxed out on space. Unitrends wants to sell a larger appliance, about 26TB (current box is 13TB usable), but may be cost prohibitive.

 

Our backup needs include:

-Offsite daily, via cloud or disk (currently do full backups on weekends, archive to disk; weekdays differentials and incrementals archived to disk)

-Rotating Monthly/quarterly/annual backups offsite.  Keep annuals forever.

-We mainly use the backups for DR, as the Netapp previous versions and snapshots work very well.

 

I know what Unitrends is offering, but wondering about other options:

-Purchasing some software and building my own storage (Storageworks said they could not do Netapp CIFS shares, but we could set up a file server, attach the shares and backup from there - seems cumbersome to me; Veeam is supposed to have the ability to backup CIFS shares in the next version?)

-Use a 2nd NetApp for Vaulting and Mirroring - either purchase a 2nd appliance and install at a remote office, or my NetApp service provider has a cloud package I could mirror to.  I would still need to do some backups to disk for permanent archives.

 

Budget wise, hoping to find something for under $25k.

 

Unitrends does NOT do incremental forevers on the CIFS, which is annoying - would love to have that feature.

 

Any suggestions are welcome.  Thanks.

Hello Experts,

   We have a FAS6280 running Ontap Version 9.1 on it (repurposed Cdot Cluster). Can we upgrade it to 9.2? I have checked on NetApp site but looks like OnTap 9.2 is not available for FAS6000 series.  Did anyone upgrade FAS6280 to 9.2 or any thoughts on it? 

 

Thanks.

OnTAP API - Can't seem to figure out how to show/list all VIF's

Hello Community,

 

First time posting, so hopefully its not a dumb question.

 

 

I've looked up and down the OnTAP API but cannot figure out a way to list and identify all VIF's (virtual interfaces).

 

The CLI makes it incredibly easy, but I can't figure out how to get the relavent info via the API.

 

Any help would be greatly appreciated.

Hi,

 

We have 4 node cluster(ontap 9.1) and we are planning to move our nfs vol to new node aggr which is newly added.

 

The first question is, can we move nfs vol nondisruptively to other node?

The second question, after move vol to new added node, which lif is going to serve to nfs vol? Because there is no lif option when you moving volume ?

 

Thanks,

Tuncay

 

 

NetApp Storage Monitoring from two different OCUM/OCPM and DFM

$

Hi There,

 

We are planning to have DC-DR for our NetApp monitoring tools OCUM & OCPM and DFM.

 

Primary site:  Site-A

Secondary site: Site-B

 

We will deploy 3 VMs in each location  [2 VMs will be used for OCUM/OCPM for C-Mode controller monitoring and 1 VM will be used for DFM which will collect the data for 7-mode controllers]

 

Both Site-A and Site-B monitoring servers will collect the data from end devices (meaning: same controller will be integrated with two different monitoring infra).

 

Kinldy let me know if this dual polling is possible. Also, confirm there will not be any impact in storage array performance.

SVM DR and the physical location of CIFS Share Information in Cdot

$
0
0

First, some background: I have just upgraded to OnTAP 9.1P8 and want to take advantage of the SVM DR feature on our CIFS SVMs.

 

The Data Protection guide indicates I should ensure that all volumes, including the root volumes, have the same names in the source and destination SVMs. Currently I have root volumes on the source and destination SVMs, and on each SVM I use root volume protection as recommended in NetApp documentation.

 

My question: how can I incorporate the source SVM's root volume into this without disrupting the SVM root volume protection on the destination? Or, should I replicate the source root volume and keep a separate volume for the destination's root volume?

 

Also: is it accurate to assume that the CIFS Share Information is stored in the root volume, and that's the reason for replicating it offsite?

 

Finally: during DR tests, we currently flexclone volumes for CIFS Servers and then use the results of a PowerShell script to create commands in an Excel spreadsheet to rebuild the shares. Very convoluted. With SVM DR I'm hoping there's an easier way to conduct the test. Any suggestions?

 

Thanks in advance for any thoughts / suggestions on these questions!


Volume size utilization

$

Hi,

 

We have created a Volume of 3.6 TB with UNIX Security Style, Deduplication and Compression enabled & Enable Fractional Reserve(100%) unchecked in OnCommand Systems Manager. 

 

There are no SnapShot or SnapMirror being configured for the volume. 

 

OS is Data OnTap 8.2.4P4 7-Mode.

 

Within that we have created a LUN of 3 TB which is mapped to a Windows Server. Current space utilization for LUN is 58%.

 

Current volume utilization is 95% with 170 Gb free.

 

I want to understand where this 400+ GB is being used.

 

Snapmirror filesys-size-fixed

$

Hello Guys,

 

Got a:
Source: On-premise system FAS2520 with Ontap 9.1.P8
Destination: AWS system with Ontap with 9.1

we have one volume snapmirror from onpremise to aws, no vserverdr, just a simple snapmirror.

I thought that the filesys-size-fixed would always be true on the destination but this does not seem to be the case.. I went then to the destination:

snapmirror break -destination-path vserver:volume
vol modify volume -vserver x -filesys-size-fixed true
vol show -vserver x -fields filesys-size-fixed: output: true
snapmirror resync -destination-path vserver:volume

and suddenly the filesys-size-fixed is false again... hence he's not automatically increasing the size on the destination volume if I increase the size in the source. Anyone has ever experienced that? I have various svmdrs running on other systems and there I have configuration on source with filesys-size-fixed true and false but the destination is always on true.
I'm not sure whether it has to do with the Ontap version or is a configuration issue?

 

Cheers,

axsys

Ontap Select 9.2, 2 Node HA one Node crashed sometimes with SCSI Error

$

Hi,

 

we have set up a 2-Node HA Ontap Select 9.2 Cluster for a customer. The cluster is working fine, but sometimes crash one node with the attached error code.

 

In this error state, the node can not be stopped. I need to force a restart of the esx host, that hosted the ontap select node.

 

After the node has been started, and the aggregate resync is completed, the ha cluster is working normal.

 

Any ideas?

 

Kind Regards

Hesitant to Deploy SVM DR

$
0
0

After a week of testing the SVM DR feature (including some great assistance on these boards and with NetApp Support), I am ready to implement it on our CIFS Server SVMs. However, there are two things giving me pause. Does anyone have insight into these two issues?

 

  1. The following line appears on the top of page 76 of the Data Protection Using SnapMirror and SnapVault Technology guide:

    ------------------------------------------------
    If the source cluster reboots, then the source SVM is operationally stopped and is locked for any management operations to avoid data corruption in case data is accessed inadvertently from both the source and destination SVMs.
    ------------------------------------------------

    This appears to say the production (source) SVM will be *stopped* during a reboot, meaning it will experience an outage when we failover/giveback to deploy OnTAP upgrades (or during unplanned failovers). Does it mean something else? I wonder what they mean by "operationally' stopped, and locked for any "management" operations. Is the SVM only "stopped" in a limited fashion? The documentation is unclear. Page 78 describes "unlocking" an SVM after a reboot, which seems to imply only "management" functions are stopped, but what this means isn't clear.

  2. Similarly, when first issuing the snapmirror resync command after creating the SVM DR snapmirror relationship, the following appears:

    ------------------------------------------------
    This Vserver has volumes which are the destination of volume-level SnapMirror relationships. A resync on the Vserver SnapMirror relationship will cause disruptions in data access. It will also convert the relationship-group-type of the volume SnapMirror relationships to "Vserver". Do you want to continue? {y|n}:
    ------------------------------------------------

    The line "a resync on the vserver SnapMirror relationship will cause disruptions in data access" (emphasis mine) doesn't give me warm fuzzies. Does this mean the production (source) SVM will experience an outage? Again, the wording isn't very clear.

 

We are on OnTAP 9.1P8. I plan to upgrade to 9.2 once P2 is released. I'm curious if the wording of the item in #2 above has been changed/improved in 9.2.

 

Any thoughts/suggestions are welcome!
