Parameters
- Query or -q
- Displays the current space management settings for the named file
system. The settings include values for the following:
- File system name
- High and low thresholds
- Premigration percentage
- Age and size factors
- Quota
- Stub file size
- Server name
- Maximum candidates
- Server stanza (HACMP only)
- 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.
