Asnodename

Use the asnodename option to allow agent nodes to back up or restore data on behalf of another node (the target node). This enables concurrent operations from multiple nodes to store data to the same target node and file space in parallel.

Your client node must be granted access to the target node by the Tivoli® Storage Manager server administrative client grant proxynode command, and you must be a root user to use the asnodename option.

When the Tivoli Storage Manager administrator grants a node proxy authority, and you use the asnodename option to become that node, you can query and restore all files as if you had root authority.

An agent node is a client node that has been granted authority to perform client operations on behalf of a target node.

A target node is a client node that grants authority to one or more agent nodes to perform client operations on its behalf.

For example, you can use the following command to back up shared data for file space stored under the node name MyCluster:
/cluster1/mydata
dsmc incremental /Users -asnodenodename=MyCluster 

You can also use the asnodename option to restore data under another node name on the Tivoli Storage Manager server. You can only restore the data that you own.

The asnodename option differs from the nodename option as follows:

  • When using the nodename option, you must enter the password for the node name you specify.
  • When using the asnodename option, you must enter the password for your client agent node to access the data stored for the client target node.

Restrictions: You cannot use the asnodename option with -fromnode and you cannot perform NAS backup using asnodename. Also, asnodename can be used for clustered systems, although no specific cluster software is supported.

Supported Clients

This option is valid for all UNIX and Linux clients.
