SnapManager for SQL Snapvault archive issue - can you crack it?

HyperDiskhead — Wed, 04 Jun 2025 19:39:57 GMT

A challenge for SMSQL lovers...

I have 3 SQL servers of 30 in total all running Snapdrive 7.1.1, SnapManager 7.2 with these 3 having issues connecting to a newly implemented 8.3.2 cluster/SVM used for Snapvaulting. I have had a Netapp technical case open, a Partner Helpdesk case after being told it was configuration by tech support and then back to tech support, escalated and now awaiting another escalation.

The issue is in adding credentials for these 3 servers to this SVM either via HTTP or HTTPS, Snapdrive hangs for 10 minutes before reporting various communication errors including "unable to get CDOT version". If default credentials are added in with the correct details for this clusters vsadmin account and then iSCSI connection attempted, it reports the same errors after a similar 10 minute timeout. Connection to non Snapvault/production SVMs within the same datacenter works.

For the 3 servers with issues, we have in summary:

We have checked Snapdrive configuration including checking connection to mgmt. LIF of SVM is being used as it was

Checked iSCSI interfaces are setup and added a secondary as one did not exist

Checked vsadmin account is setup correctly and it was

Checked DNS and tried via IP with the same result, tried many host file entry edits to test over past week and no changes. Resolution/reverse resolution is the same as for servers without the issue

Checked network route and is taking the same path as data is from servers without the issue

Observed that connection via HTTP or S is established in netstat –a output

Saw no evidence in logs on storage using event log show *iscsi*

Created new account as a test with vsadmin role, no change

Tried Snapdrive 7.1.3 and 7.1.1 both compatible with CDOT 8.3.2, circumnavigated Snapdrive via adding the ISCSI connection address directly into MS ISCSI Initator as a discovery portal which allowed connection directly through that software

Rebooted filer and made no difference

Created new SVM, tested from servers without issue and could connected, tested from 3 servers with issue and could not

Saw that in wireshark traces the "Client Hell" SSL headed packet is not replied to from the cluster with the usual "Server Hello, Certificate" message suggesting comms are stalling somewhere - this is where it is at with Netapp.

Any ideas on anything else to try? Let me know if you want any further data, I am in this for the long haul..:)

Cheers!

can you make sure you have the HTTP access for vsadmin account for the SVM.

Example :

mvaqa-fas8080-03a-03b::*> security login show -vserver neeraj

Vserver: neeraj

Authentication Acct Is-Nsswitch

User/Group Name Application Method Role Name Locked Group

---------------- ----------- --------- ---------------- ------ -----------

snapcenter http password vsadmin no no ---------------------> Account is not lock for http.

snapcenter ontapi password vsadmin no no

snapcenter ssh password vsadmin no no

1. Account is in lock state.

i.e

mvaqa-fas8080-03a-03b::*> security login show -vserver neeraj

Vserver: neeraj

Authentication Acct Is-Nsswitch

User/Group Name Application Method Role Name Locked Group

---------------- ----------- --------- ---------------- ------ -----------

snapcenter http password vsadmin no yes-----------------------------> account is lock for http.

snapcenter ontapi password vsadmin no yes

snapcenter ssh password vsadmin no yes

let me now.

Hey Neeraj,

See below, I am connecting to CLUSTERSVM edited SVM name.

hi can you add Http for your SVM, i dont see that added for SVM and that why SDW not able to connect to http/Https.

example to enable http for svm:

mva-fas8080-::*> security login create -user-or-group-name snapcenter -application http -authentication-method password -role vsadmin -vserver SVM-name

once add the http for SVM try the adding svm to SDW.

thanks
