Shutting down VCS (phased only)

Shutdown VCS on remaining nodes that are not being upgraded to preventing them from rejoining the cluster.

 To shut down the cluster

  1. Separate the nodes that are not being upgraded from those that are.
  2. Check to see if there are frozen CVM and SFCFS groups, enter

    # /opt/VRTSvcs/bin/hastatus -sum

    If the groups are frozen, unfreeze CVM and SFCFS groups using the following commands for each group:

    1. Make configuration read/write:

# /opt/VRTSvcs/bin/haconf -makerw

    1. Unfreeze the group:

      # /opt/VRTSvcs/bin/hagrp -unfreeze group -persistent

    2. Save the configuration:

# /opt/VRTSvcs/bin/haconf -dump -makero

  1. Offline the group on each of the remaining nodes of the cluster:

    # hagrp -offline group -sys system01

    # hagrp -offline group -sys system02

    # hagrp -offline group -sys system03

    # hagrp -offline group -sys system04

where group is the VCS service group that has the CVMVolDg and CFSMount resource.

  Note   Repeat step 2 for each SFCFS service group.

  1. Check and repair each file system:

    # fsck -t vxfs /dev/vx/dsk/diskgroup/volume

      Note   Repeat step 3 for each file system.

  2. On each node that is not being upgraded, shutdown VCS, enter the following commands:

    # /opt/VRTSvcs/bin/hastop -local

# /etc/init.d/vxfen stop

# /opt/VRTS/bin/fsclustadm cfsdeinit

# /etc/init.d/gab stop

# /etc/init.d/llt stop

  1. Proceed to Updating the configuration and confirm startup (phased or full).
