InfoScale™ 9.0 Storage Foundation Cluster File System High Availability Configuration and Upgrade Guide - Solaris

To prepare the second subcluster

1. On the second half of the cluster, stop all applications that are not configured under VCS. Use native application commands to stop the application. [Downtime starts now.]
2. On the second half of the cluster, unmount the VxFS and CFS file systems that are not managed by VCS. Enter the following:

   # mount -p | grep vxfs

   Verify that no processes use the VxFS and CFS mount point. Enter the following:

   # fuser -c mount_point

   Stop any processes using a VxFS and CFS mount point with the mechanism provided by the application.

   Unmount the VxFS and CFS file system. Enter the following:

   # umount /mount_point

3. On the second half of the cluster, unfreeze all the VCS service groups on all the nodes using the following commands:

   # haconf -makerw
   # hagrp -unfreeze group_name -persistent
   # haconf -dump -makero

4. On the second half of the cluster, bring all the VCS service groups offline, including CVM group. Enter the following:

   # hagrp -offline group_name -sys sys4

5. On the second half of the cluster, verify that the VCS service groups are offline. Enter the following:

   # hagrp -state group_name

6. Stop VCS on the second half of the cluster. Enter the following:

   # hastop -local

7. On the second half of the cluster, stop the following SFCFSHA modules: GLM, ODM, GMS, VxFEN, GAB, and LLT. Enter the following:

   For Solaris 11:

   # modunload -i [modid of vxglm]
   # /usr/sbin/svcadm disable -st vxodm
   # modunload -i [modid of vxgms]
   # /usr/sbin/svcadm disable -st vxfen
   # /usr/sbin/svcadm disable -st gab
   # /usr/sbin/svcadm disable -st llt
   

   Or

   You can enter the following to stop all these processes:

   # ./installer - stop
