Solaris Volume Manager Administration Guide

ProcedureHow to Cancel a Volume Resynchronization Process

  1. Assume the Primary Administrator role, or become superuser.

    The Primary Administrator role includes the Primary Administrator profile. To create the role and assign the role to a user, see Chapter 2, Working With the Solaris Management Console (Tasks), in System Administration Guide: Basic Administration.

  2. Use the metastat command to view the status of the RAID-1 volume and associated submirrors.


    # metastat mirror-name

    or


    metastat -a

  3. Use the metasync -c volume command to cancel the resynchronization process.

Example 11–17 Canceling a Volume Resynchronization Process

The following example illustrates how to cancel the resynchronization process on a volume that is part of the disk set blue. Notice that the submirrors are in the “Resync cancelled” state after running the metasync command.


# metastat -a

    Submirror 0: blue/d1
      State: Resyncing
    Submirror 1: blue/d2
      State: Okay
