Viewing the Status of a Relayout

Online relayout operations take some time to perform. You can use the vxrelayout

command to obtain information aboutthe status ofa relayout operation. For example, the

command:

# vxrelayout status vol04

might display output similar to this:

STRIPED, columns=5, stwidth=128--> STRIPED, columns=6, stwidth=128

Relayout running, 68.58% completed.

In this example, the reconﬁguration of a striped volume from 5 to 6 columns is in

progress, and is just over two-thirds complete.

See the vxrelayout(1M) manual page for more information about this command.

If you speciﬁed a task tag to vxassist when you started the relayout, you can use this

tag with the vxtask command to monitor the progress of the relayout. For example, to

monitor the task tagged as myconv, enter:

# vxtask monitor myconv

Controlling the Progress of a Relayout

You can use the vxtask command to stop (pause) the relayout temporarily, or to cancel

it altogether (abort). If you speciﬁed a task tag to vxassist when you started the

relayout, you can use this tag to specify the task to vxtask. For example, to pause the

relayout operation tagged as myconv, enter:

# vxtask pause myconv

To resume the operation, use the vxtask command:

# vxtask resume myconv

For relayout operations that have not been stopped using the vxtask pause command

(for example, the vxtask abort command was used to stop the task, the transformation

process died, or there was an I/O failure), resume the relayout by specifying the start

keyword to vxrelayout, as shown here:

# vxrelayout -o bg start vol04

Note If you use the vxrelayout start command to restart a relayout that you

previously suspended using the vxtask pause command, a new untagged task is

created to complete the operation. You cannot then use the original task tag to

control the relayout.
