How to Check For and Fix Bad Mediator Data

Perform this procedure to repair bad mediator data.

Before You Begin

Ensure that you have added mediator hosts as described in How to Add Mediator Hosts.

  1. Display the status of the mediator data.
    phys-schost# medstat -s setname
    –s setname

    Specifies the disk set name.

    See the medstat(8) man page for more information.

  2. Check the Status field of the medstat output for each mediator host.
    • If the status is Ok, no error condition exists.
    • If the status is Bad, repair the affected mediator host.
  3. Assume the root role on the node that owns the affected disk set.
  4. Remove all mediator hosts with bad mediator data from all affected disk sets.
    phys-schost# metaset -s setname -d -m mediator-host-list
    –s setname

    Specifies the disk set name.

    –d

    Deletes from the disk set.

    –m mediator-host-list

    Specifies the name of the node to remove as a mediator host for the disk set.

  5. Restore each mediator host that you removed in Step 4.
    phys-schost# metaset -s setname -a -m mediator-host-list
    –a

    Adds to the disk set.

    –m mediator-host-list

    Specifies the name of the node to add as a mediator host for the disk set.

    See the mediator(4D) man page for details about mediator-specific options to the metaset command.
