Consolidate Sessions
Consolidates sessions of a multistream context.
This table displays a list of ongoing backup sessions, providing the following information:
Specifies the unique identification number that OneFS assigns to the session.
Specifies the time that has elapsed since the session started.
Specifies the amount of data that was transferred during the session.
Specifies the average throughput of the session over the last five minutes.
Specifies the IP address of the backup server that the data management application (DMA) is running on. If a three-way Network Data Management Protocol (NDMP) backup or restore session is currently in progress, the IP address of the remote tape media server also appears.
Specifies the current state of the data mover and the data server. The first word describes the activity of the data mover. The second word describes the activity of the data server.

The data mover and data server send data to and receive data from each other during backup and restore sessions. The data mover is a component of the backup server that receives data during backups and sends data during restore sessions. The data server is a component of OneFS that sends data during backups and receives information during restore sessions.

The following states might appear:

The data mover or data server is currently sending or receiving data.
The data mover is temporarily unable to receive data. While the data mover is paused, the data server cannot send data to the data mover. The data server cannot be paused.
The data mover or data server is not sending or receiving data.
The data mover or data server is waiting to connect to the data server or data mover.
The type of session (backup or restore) that is currently in progress. If no session is in progress, None appears in this field.
Backup {M} {F} [L[0-10] | T0 | Ti | S[0-10]] {r | R}


[ a ]—a is required

{ a }—a is optional

a | b—a or b but not at the same time

M—Multi-stream backup

F—File list



S—Snapshot mode

s—Snapshot mode and a full backup (when root dir is new)

r—Restartable backup

R—Restarted backup

0-10—Dump Level

Restore {M|s}[F | D | S]{h}


M—Multi-stream restore

s—Single-threaded restore (when RESTORE_OPTIONS=1)

F—Full restore


S—Selective restore

h—Restore hardlinks by table

If a session is currently in progress, specifies the /ifs directories that are affected by the session. If a backup session is in progress, displays the path of the source directory that is being backed up. If a restore session is in progress, displays the path of the directory that is being restored along with the destination directory to which the tape media server is restoring data. If you are restoring data to the same location that you backed up your data from, the same path appears twice.
Specifies the name of the tape or media changer device that is communicating with the cluster.
Specifies how OneFS interacts with data on the backup media server, as follows:
Specifies that OneFS is reading and writing data during a backup session.
Specifies that OneFS is reading data during a restore session.
Specifies that the DMA has access to tape drives, but the drives do not contain writable tape media.
Pause, restart, or terminate an active session.
