With the online modification of the packages, the following are the constraints for the listed
attributes:

You can change the storage system names for the attribute, but changing the array is not
supported.
• DC1_STORAGE_SYSTEM_USER, DC2_STORAGE_SYSTEM_USER
You can change the user name, but you must recreate the password files for the newly created
user name.
• DC1_RC_VOLUME_GROUP, DC2_RC_VOLUME_GROUP
You can change the Remote Copy Volume Group name, but you must use the same disks as

You must specify the target name for the attribute as configured for the Remote Copy Volume
