Resolving storage problems for active data pools

Edit online

You might experience difficulty in storing data in an active data pool by using the simultaneous-write function or by issuing the COPY ACTIVEDATA command.

Before data can be stored in an active data pool, you must establish a policy to allow the data into the pool. The node that owns the data must be assigned to a domain whose active data pool is listed in the domain ACTIVEDESTINATION field. Issue the following command to determine if the node is assigned to a domain that authorizes storing into the active data pool:

QUERY NODE  node_name F=D

The Policy Domain Name field lists the domain to which the node is assigned. Issue the following command to determine if the active data pool is listed in the domain ACTIVEDESTINATION field:

QUERY DOMAIN domain_name F=D

If the active data pool is not listed, issue the following command to add the active data pool to the list:

UPDATE DOMAIN domain_name ACTIVEDESTINATION=active-data_pool_name

Tip: After you issue the UPDATE DOMAIN domain_name ACTIVEDESTINATION=active-data_pool_name command, all nodes assigned to the domain are authorized to store data in the active data pool. If having the nodes assigned to the domain authorized to store data is not acceptable, you must create a new domain for those nodes whose data you want stored in the active data pool and assign those nodes to the newly created domain.
