Resolving the issue of data being sent directly to the server

Edit online

The client summary statistics do not report any bytes transferred LAN-free.

Before you begin

The client reports the bytes sent LAN-free by issuing the ANE4971I LAN-free Data Bytes: xx KB command. Similarly, the server does not report any instance of ANR0415I Session SESS_NUM proxied by STORAGE_AGENT started for node NODE_NAME for this node and storage agent, indicating that the LAN-free proxy operation was done for this client node.

The client will only attempt to send data LAN-free with the storage agent if the primary storage pool destination in the server storage hierarchy is LAN-free. A server storage pool is LAN-free-enabled for a given storage agent if one or more paths are defined from that storage agent to a SAN device.

About this task

To determine if the storage pool destination is configured correctly, perform the following procedures:

Procedure

  1. Issue the QUERY NODE nodeName command to report the policy domain to which this node is assigned.
  2. Issue the QUERY COPYGROUP domainName policySetName mgmtclassName F=D command for the management classes that this node would use from their assigned policy domain. Note that this command reports information for backup files. To query copy-group information for archive files, issue the QUERY COPYGROUP domainName policySetName mgmtclassName TYPE=ARCHIVE F=D command.
  3. Issue the QUERY STGPOOL stgpoolName command, where stgpoolName is the destination reported from the previous QUERY COPYGROUP queries.
  4. Issue the QUERY DEVCLASS deviceClassName command for the device class used by the destination storage pool.
  5. Issue the QUERY LIBRARY libraryName command for the library reported for the device class used by the destination storage pool.
  6. Issue the QUERY DRIVE libraryName F=D command for the library specified for the device class used by the destination storage pool. If no drives are defined to this library, review the library and drive configuration for this server and issue the DEFINE DRIVE command to define the needed drives. If one or more of the drives report ONLINE=No evaluate why the drive is offline and, if possible, update it to online by issuing the UPDATE DRIVE libraryName driveName ONLINE=YES command.
  7. Issue the QUERY SERVER command to determine the name of the storage agent as defined to this server.
  8. Issue the QUERY PATH stgAgentName command, where stgAgentName is the name of the storage agent defined to this server and reported in the QUERY SERVER command. Review this output and verify that one or more paths are defined for drives defined for the device class used by the destination storage pool. If no paths are defined for this storage pool, issue the DEFINE PATH command to define the needed paths. Also, review this output and verify that the path is online. If paths are defined but no paths are online, update the path to online by issuing the UPDATE PATH srcName destName SRCTYPE=SERVER DESTTYPE=DRIVE ONLINE=YES command.
