Proxy v2 and C-mode

[ Edited ]

hi there,

I am reading the documentation and I have a simple question. The set-up on the doc is using a C-mode cluster. I can see in the configuration file:

 

/u01/app/oracle/product/11.2.0/dbhome_1/config/rman_ntap_nfs_sdb.conf

FILER=10.63.164.18:rmanuser18/1R1w1q1x0R0z0S0r0J1H

FILERPASS_ENCRYPTED=YES

VOLUMES=10.63.164.18:mml_11g_oradata

VALIDATE_VOLUMES=DATA

SNAME=

SNAP_TYPE=

PROTOCOL=nfs

DB_LUN=

DB_MOUNTPOINT=10.63.164.18:mml_11g_oradata:/mml_11g_oradata

...

 

I dont understand how the lif used to serve data, will be used later on to take/restore snapshots. How is the proxy retrieving the management IP ?

I would also like how is the rmanuser18 configured on a C-mode cluster, which minimum privileges should have?

 

Thanks a lot!

Ruben

Re: Proxy v2 and C-mode

The rman account just needs "ontapi".

The proxy communicates through the IP specified in config file.  It doesn't retrieve the management IP.  The firewall policy on the lif specified in the conf file needs to "mgmt" otherwise the proxy can't talk to vserver.

Re: Proxy v2 and C-mode

Thanks Doug. This is interesting. I thought we need to pass always by cluster management IP to do that kind of operations. Strange there is no default firewall policy at least on Ontap 8.1.1 to achieve this.

I imagine just https and ssh should be open.

Re: Proxy v2 and C-mode

Please could you provide the configuration of the rmanuser18, which role has assigned? You connect to the data lif via ZAPI?

I was talking with Netapp support and the supporter just commented that one can not take snapshots using a data lif, due the fact that the lif can be migrated to any physical port of any controller.

Thanks for your time!

In my setup it's like below and it works.
