Back up the GDS configuration information, if you want to copy disks that are registered in the local or shared class of the GDS by using the method described in the "When not using the mirroring among servers" of "When making the GDS configuration of the copy destination the same as the configuration of the copy source" in "K.1.3 Copying Method for Data Disk (GDS)."
Note
This procedure is unnecessary when mirroring among servers is used.
Back up the local class and shared class object configurations for GDS on the copy source server.
Execute the following procedure on any node of the copy source server. If there are multiple classes, perform this operation for all classes.
Example: The object configuration data of class Class1 is output to file /var/tmp/Class1.conf.
# sdxconfig Backup -c Class1 -o /var/tmp/Class1.confSave the GDS configuration data in a file on the copy source server. Output the class configuration data of all GDS classes to files.
Example: The data of class Class1 is output to the /var/tmp/Class1.info file
# sdxinfo -c Class1 -e long > /var/tmp/Class1.info
