3. Run the HP-UX touch command with the DETACH flag, in the Site Controller Package directory
touch DETACH
4. Halt the Site Controller Package.
cmhaltpkg <site_controller_package_name>
The Site Controller Package halts without halting the complex workload packages. The Site Controller
Package leaves the Site Safety Latch open on this site. The DETACH mode file is automatically
removed by the Site Controller Package when it halts. After the maintenance procedures are
complete, restart the Site Controller Package on the same site where it was previously halted in
the DETACH mode. You cannot start the Site Controller Package on a different site node. Run the
following command to start the Site Controller Package:
cmrunpkg <site_controller_package_name>
Enable global switching for the Site Controller Package.
cmmodpkg –e <site_controller_package_name>
When the Site Controller Package is halted in the DETACH mode, the active complex workload
configuration on the site can be halted and restarted at the same site as the Site Safety Latch is
still open in the site.
Upgrading the Site Controller Package
When using Metrocluster with Continuous Access XP A.10.00 or later, Metrocluster with Continuous
Access EVA A.05.00 or later, or Metrocluster with EMC SRDF A.09.00 or later, then the Site
Controller Package can be upgraded to use the Metrocluster modules. By upgrading the Site
Controller Package, the environment file parameters will be included in the Site Controller Package
configuration file. The Metrocluster environment file need not be edited or distributed to all the
nodes. For more information on configuring modular packages, see the Configuring Modular
Packages section in the respective chapters of this manual.
Complete the following procedure to upgrade the Site Controller Package in a cluster:
1. Upgrade the Site Controller Package to the latest version of Metrocluster.
cmmakepkg -u pkg_name -m dts/sc output_pkg.ascii
2. Add the array-specific module parameters to the Site Controller Package configuration file.
For example, when using Metrocluster with EMC SRDF:
cmmakepkg -i output_pkg.ascii -m dts/mcsrdf -t path to the
environment file migrated_output_pkg.ascii
When using Metrocluster with Continuous Access EVA:
cmmakepkg -i output_pkg.ascii -m dts/mccaeva -t path to the
environment file migrated_output_pkg.ascii
When using Metrocluster with Continuous Access XP:
cmmakepkg -i output_pkg.ascii -m dts/mcxpca -t path to the
environment file migrated_output_pkg.ascii
3. Validate the package configuration file.
cmcheckconf -P migrated_output_pkg.ascii
4. Apply the package configuration file.
cmapplyconf -P migrated_output_pkg.ascii
Deleting the Site Controller Package
Complete the following procedure to delete Site Controller package in a cluster:
