Re: 8.3 and snapdiff Backup with TSM

sstrznwra · ‎2015-07-09

Hello

We use

IBM Tivoli Storage Manager

Command Line Backup-Archive Client Interface

Client Version 7, Release 1, Level 2.2

and

NetApp Release 8.3 Clustered Mode

This Version is supported for snapdiff on Netapp Filers

We try a snapdiff Backup on a SVM, we do the following

Management Server: xyz.domain.at
File Server: nas01
Volume: vol1
Share: vol1$
User: domain\tsm_filer

On TSM Client:
set password -type=filer xyz.domain.at domain\tsm_filer
set netappsvm nas01.domain.at xyz.domain.at domain\tsm_filer

On Filer:
CreateUser domain\tsm_filer angelegt
Vserver: xyz.domain.at
                             Authentication                  Acct
User/Group Name Application Method         Role Name        Locked
---------------- ----------- -------------- ---------------- ------
domain\tsm_filer ontapi      domain         admin            -
domain\tsm_filer http        domain         admin            -

Share mapping on TSM Client
net use p: \\nas01\vol1$ /u:domain\tsm_filer

Net use OK, and we can access the share read-write

Start snapdiff Backup on TSM Client:
tsm> incr p: -snapdiff

Error:
07/09/2015 14:56:35 ANS2837E Unable to access the required stored NetApp filer credentials (user id and password) for filer 'nas01'.
Make sure the SET PASSWORD -TYPE=FILER command was specified correctly to store the credentials.
07/09/2015 14:56:35 ANS2832E Incremental by snapshot difference failed for \\nas01\vol1$. See the error log for details.

07/09/2015 14:56:36 ANS5283E The operation was unsuccessful.

What are we doing wrong ?

Hi,

I'm having exact the same issue.

But I'm unable to register the password following the doc.

I will open a case a IBM

tom_taelman · ‎2015-07-10

Following the docs for TSM 7.1.2.2 you should enter the following commands:

dsmc set netappsvm svm_example.com cms_filer1.example.com svm_2
dsmc set password cms_filer1.example.com user_name password

But the set password is not accepted for me

Has anyone found an solution?

I have configured as described above but when I started an SnapDiff-Backup I got the error-message "ANS2041E Snapshot Differencing support is not available on the specified NetApp filer. "

On the cluster I see in the mgwd.log

"Unable to find API: vfiler-list-info :: ONTAPI :: Error"

It looks like the TSM-Client is using 7-mode APIs and not C-mode APIs.

Hi ... just wondering how you got around the problem... we are having the exact same problem. Our Netapp is running cDot 8.3.1 and our TSM server is V6.3.3.

any update on this? Currently trying to run it on ONTAP 9.1

its complaining about API errors and support.

Hello! Just one question.

Was the snapdiff function working before upgrading ontap to 9.1 or is it a new installation? with ONTAP 9.1

(which im currently running on my sites too)

you need at least TSM/SpectrumProtect BAclient Version 8.1.x to be supported.

in addition please make sure that you can connect from the system doing the snapdiff backup jobs to port tcp/22 (ssh) and tcp/443 (https) to the lif handling the cluster management interface.

cluster01::> net int show -lif cluster_mgmt
  (network interface show)

Post updated due to formatting issues and link correction.

Hello,

we have the same problem. Has the issue been resolved?

Thank you very much

Hello!

we've just migrated our first vFiler from 7mode 8.2.1 to cDOT 8.3.2 - and tsm snapdiff Backup works like a charm.

But you have to be careful how to setup the connection from the TSM BAclient to the cDOT Filer.

you need TSM BackupArchive Client Version 7.1.4.x (recommended is 7.1.4.2 due to TSM bug IT12436 http://www-01.ibm.com/support/docview.wss?uid=swg1IT12436
a NetApp cDOT Security Role on the cDOT Cluster, which is to be backuped with TSM - of course you could use the admin role - but it's a security concern.
this example grants very wide readonly rights for the role used, but it works - of course you can tune and optimize the rights needed for the role used in your installation.
i've not found a sample listing for the needed commands for the SnapDiff Usage of TSM in cDOT environment.

security login role create -role tsm-snapdiff-role -cmddirname DEFAULT -access readonly
security login role create -role tsm-snapdiff-role -cmddirname "vserver" -access readonly
security login role create -role tsm-snapdiff-role -cmddirname "volume snapshot" -access all

a NetApp cDOT User on the cDOT Cluster, which is associated with the just created Security Role. In the first line you have to define a password for that user, please use a complex one and remind that password for later use on the TSM BackupArchive Client System (in this example i've used a local cDOT User, i've not yet tried a domain-user for this - if you want to do it that way, you have to setup a domain tunnel for it in the cDOT Cluster - syntax for this is described here
```
security login create -username snapdiff-user -application http -role tsm-snapdiff-role -authmethod password
security login create -username snapdiff-user -application ontapi -role tsm-snapdiff-role -authmethod password
```
the just created user has to be defined on the System which is responsible for backup of the CIFS Shares of the NetApp cDOT Cluster-System vServers/SVMs.
just log into that System (in my example its a Windows Server System) and define it in the Client Option File Registry Hive with the TSM-Tools
define the clustered Data Ontap Management Cluster Connection:
```
dsmc set netappsvm <hostname of svm sharing the volume> <fqdn of netapp cluster management server> <svm name in cDOT-cluster> -optfile=<optfile of TSM-Node used for Backup the CIFS-Shares>

example: dsmc set netappsvm svm1 cluster1.contoso.com svm1 -optfile=svm1.opt
```

after that, the login credentials defined on the cDOT system must be defined on the TSM BAclient System responsable for the Backup too

dsmc set password -type=filer <fqdn of cluster mgmt, running the svm> <password> -optfile<optfile of the tsm-node used for the backup>
dsmc set password -type=filer <hostname of svm owning the volume> <password> -optfile<optfile of the tsm-node used for the backup>

example:

dsmc set password -type=filer cluster1.contoso.com snapdiff-user password -optfile=svm1.opt		
dsmc set password -type=filer svm1 snapdiff-user password -optfile=svm1.opt

finally, you can try a backup with

net use w: \\svm1\share1 /persistent:no

and

dsmc i w: -snapdiff -snapdiffhttps -optfile=svm1.opt

the result should show something like this:

C:\Program Files\Tivoli\TSM\baclient>dsmc i w: -snapdiff -snapdiffhttps -optfile=svm1.opt

thats an example that works at my site here - please feel free to comment or like/kudo/accept as a solution for you.

sorry for being late in my efforts, but we had so much work to do here in the migration project that this writeup had to wait for an extra-minute ...
