You must have root user authority to use this command.

The dsmmigfs command used with the query parameter displays the current space management settings for a file system.

Syntax

>>-dsmmigfs--query--+--------------+--+---------------------+--><
                    | .----------. |  | .-----------------. |
                    | V          | |  | V                 | |

Parameters

Query or -q
Displays the current space management settings for the named file system. The settings include values for the following:

options

-Detail or -v
Displays HSM settings for each file system. Displays options that the HSM client does not display in the standard format, such as the maximum number of candidates that are located during one reconciliation.

For AIX GPFS file systems only: The dsmmigfs -query command displays only locally-managed file systems. The dsmmigfs q -d command displays information for all space-managed file systems within the local GPFS node set. The HSM client displays the following additional information:

  • Node name for each node ID and frame ID for both the owner and the preferred nodes.
  • Preferred node ID. The preferred node defines the node where HSM was initially added to the filesystem.
  • Frame ID.
  • Current owner node ID. The owner node ID defines the node that is currently managing the filesystem.
  • GPFS node set ID.

The normal dsmmigfs query will not provide any GPFS-specific information (no node set ID).

Note:
The failover environment is active on the local node. The dsmmigfs query -detail displays the current status of the local failover environment (either active or inactive).

-failover or -f
Provides a status overview of the failover environment of all HSM-managed SP nodes. The output displays the status for the node name, node ID and frame ID. It can be any of the following:
  • Active. The node participates in the failover environment within the local GPFS node set.
  • Deactivated by User. You disabled failover using the dsmmigfs disableFailover command.
  • Deactivated by HSM. The HSM client disabled failover because of an unrecoverable condition.

filesystemspec
The file system name that displays current space management settings. The default is all file systems to which space management has been added.

Examples

Task Command
Display the current space management settings for the /migfs2 file system. dsmmigfs query /migfs2
