Managing NAS file server nodes

Edit online

You can query, update, rename, and remove NAS file server nodes.

Procedure

Use one of the following commands to manage NAS file server nodes:
Command Procedure
QUERY NODE To query a node, issue the QUERY NODE command with the appropriate parameters. For example, if you want to query the NAS node NASNODE1, issue the following command:
query node nasnode1 type=nas
UPDATE NODE To update a node, issue the UPDATE NODE command with the appropriate parameters. For example, if you created a new policy domain that is named NASDOMAIN for NAS nodes and you want to update the node NASNODE1 to include the node in the new domain, issue the following command: 
update node nasnode1 domain=nasdomain
RENAME NODE To rename a NAS node, you must also rename the corresponding NAS data mover; both must have the same name.
For example, to rename NASNODE1 to NAS1, complete the following steps:
  1. Delete all paths between the data mover NASNODE1 and libraries and between the data mover NASNODE1 and drives.
  2. Delete the data mover that is defined for the NAS node.
  3. To rename NASNODE1 to NAS1, issue the following command:
    rename node nasnode1 nas1
  4. Define the data mover by using the new node name. In this example, you must define a new data mover that is named NAS1 with the same parameters that were used to define NASNODE1.
    Important: When you define a new data mover for a node that you renamed, ensure that the data mover name matches the new node name. Also, ensure that the new data mover parameters are duplicates of the original data mover parameters. Any mismatch between a node name and a data mover name or between new data mover parameters and original data mover parameters can prevent you from establishing a session with the NAS file server.
  5. For SCSI or 349X libraries, define a path between the NAS data mover and a library only if the tape library is physically connected directly to the NAS file server.
  6. Define paths between the NAS data mover and any drives that are used for NDMP operations.
REMOVE NODE To remove a node, complete the following steps:
  1. Delete any virtual file space definitions for the node.
  2. Delete all paths between the data mover and libraries and between the data mover and drives.
  3. Delete the node. For example, if you want to remove a node that is named NAS1, issue the following command:
    remove node nas1
