This section describes how to change the operating environment for non-cluster operations.
Change the IP address of a Storage Management Server as follows.
If only a physical IP address should be changed and the Storage Management Server uses a logical IP address, then perform only steps 2 and 7. Otherwise, perform all steps.
It checks whether the Storage Management Server being changed also serves as a Storage Server. If this is the case, and if the Storage Server is defined as a replication source or replication destination volume using a replication management function, delete the configuration of the source / replica volume with reference to "Deleting a source volume or replica volume" in the "ETERNUS SF AdvancedCopy Manager Operator's Guide" for the operating system of the target Storage Management Server.
On the Storage Management Server, change the system IP address.
On the Storage Management Server, execute the management server information change command. For details of this command, refer to "stgcmmodnode (Management server information change command)" in the "ETERNUS SF AdvancedCopy Manager Operator's Guide" for the operating system of the target Storage Management Server.
On all the Storage Servers managed by the Storage Management Server, execute the management server information change command. For details of this command, refer to "stgcmmodnode (Management server information change command)" in the "ETERNUS SF AdvancedCopy Manager Operator's Guide" for the operating system of the target Storage Server.
On all the Tape Servers managed by the Storage Management Server, execute the management server information change command. For details of this command, refer to "stgcmmodnode (Management server information change command)" in the "ETERNUS SF AdvancedCopy Manager Operator's Guide" for the operating system of the target Tape Server.
On the Storage Management Server, restart the daemons of AdvancedCopy Manager. For information on restarting daemons, refer to "Chapter 2 Starting and Stopping Daemons".
If the replication management function is used, reconfigure the replication management environment.
Refer to "Replication operations" in the "ETERNUS SF AdvancedCopy Manager Operator's Guide" that is applicable to the Storage Management Server operating system, and perform the tasks under "Preparations", starting with "Replication source volume settings and replication destination volume settings".
Note
For information on changes in cluster operation, refer to "9.4.2.1 Changing the IP address of Storage Management Server transaction".
Change the IP address of a Storage Server as follows.
This step is not necessary if the Storage Server uses a logical IP address and only a physical IP address is being changed.

Changing the device configuration refers to any of the following:
Mount name change
Change from File System operation to RawDevice operation
Capacity change of partitions (mainly for re-creation of LUN mapping)
Start position for change of partitions (mainly for re-creation of LUN mapping)
Change the device configuration by the following procedure. This processing is executed for all volumes on the disk where the volume whose device configuration is to be changed is located.
Check whether there is a transaction volume on the target disk that needs to be backed up. If it does, delete the transaction volume. For information on deleting a transaction volume, refer to "5.5.4.1 Deleting a transaction volume".
Check whether a backup volume exists in the target disk. If it does, delete the backup volume. For information on deleting a backup volume, refer to "5.5.4.2 Deleting a backup volume".
Change the device configuration.
Because the post-change device configuration needs to be reflected in the AdvancedCopy Manager data set, execute device information change processing for AdvancedCopy Manager. For details on changing the device information, refer to "5.3.3 Fetching device information on a Storage Server".
Reset the deleted transaction volume or backup volume. For details on adding the transaction volume or backup volume, refer to "5.3.5 Setting the operation type for a device".
Point
If the device configuration is changed (step 3) before the transaction volume and backup volume are deleted (steps 1 and 2), history information cannot be deleted and synchronized backup processing cannot be cancelled, thereby possibly disabling deletion of the transaction volume and backup volume. In this event, set the emergency operation mode, and delete history information or cancel synchronized backup processing.
For details on the emergency operation mode, see "11.2.2.10 acmhistdel (History information delete command)" and "11.2.2.12 acmcancelsync (Synchronous backup cancel command)".
The Storage Management Server is equipped with two or more network cards.
The IP address for GUI connection (that was specified during Storage Management Server installation) can be changed using the GUI connection information setting command, in cases when a Web GUI screen communicates with a Storage Server via an IP address.
For details on the GUI connection information setting command, refer to "11.3.3 stgguiipset (GUI connection configuration command)".
Note
If the Storage Management Server is equipped with two or more network cards, the settings must be defined on the client side. For details of how to specify these setting, refer to "Settings of authentication-related files" in the "ETERNUS SF AdvancedCopy Manager GUI User's Guide" for the operating system of the target client.
When a user is deleted who was specified as the "repository access user" in setup when AdvancedCopy Manager was installed, or when the user's password is changed by the operating system, the information of a "repository access user" must be reconfigured using the repository access user change command.
For details on the repository access user change command, refer to "11.3.2 stguserset (Repository access user change command)".
Note
For information on changes in cluster operation, refer to "9.4.2.7 Change of password or deletion of the repository access user".
