Example 1 – Migrating an Existing Resource to a New Resource Type Version

This example shows the migration of an existing resource to a new resource type version. Note that the new resource type package contains methods located in new paths. Because the methods will not be overwritten during the installation, the resource does not need to be disabled until after the upgraded resource type is installed.

This examples assumes the following.

• New resource type version is 2.0

• Tunability from previous version is “when_offline”

• Resource name is “myresource”

• Resource type name is “myrt”

• New RTR file is in /opt/XYZmyrt/etc/XYZ.myrt

• There are no dependencies on the resource to be migrated

• The resource to be migrated can be taken offline while leaving the containing resource group online

(Install the new package on all nodes according to vendor's directions.)
# scrgadm -a -t myrt -f /opt/XYZmyrt/etc/XYZ.myrt
# scswitch -n -j myresource
# scrgadm -c -j myresource -y Type_version=2.0
# scswitch -e -j myresource
