This section explains the environment settings for using the Storage Cluster Continuous Copy function in AdvancedCopy Manager CCM.
Configure settings according to the following procedure.
Creating User Account
Create a user for using AdvancedCopy Manager CCM.
Refer to "2.1 Creating User Account".
Settings Access Volume
When operating the Copy command via SAN, configure the ETERNUS Disk storage system access volume. Set the access volume for the respective ETERNUS Disk storage systems on the Primary Storage and Secondary Storage.
Refer to "2.2 Access Volume Settings" for the method of access volume settings.
Note
A TFOV cannot be set as an access volume.
Registering Advanced Copy License
In order to execute Advanced Copy, register the Advanced Copy license using the license management function.
Register the Advanced Copy license for the respective ETERNUS Disk storage systems on the Primary Storage and Secondary Storage.
Refer to "Registration of License" in the Installation and Setup Guide to register the Advanced Copy license.
Registering ETERNUS Disk Storage System
Execute the acarray add command, and register the respective ETERNUS Disk storage systems on the Primary Storage and Secondary Storage in AdvancedCopy Manager CCM.
Refer to "2.4 Registering ETERNUS Disk Storage System" for registering ETERNUS Disk storage system procedure.
Note
The Copy command via SAN and Copy command via LAN cannot be used simultaneously when the Storage Cluster Continuous Copy function is used. Register the same communication method on the respective ETERNUS Disk storage systems on the Primary Storage and Secondary Storage.
Creating Copy Groups
Specify the ETERNUS Disk storage system for the Primary Storage and Secondary Storage with the -a option and -tfoa option of the acgroup create command.
With the -tfoa option, specify an ETERNUS Disk storage system belonging to a TFO group that is paired with a TFO group belonging to an ETERNUS Disk storage system specified with the -a option.
Refer to "2.5 Creating Copy Groups" and the acgroup create command for creating.
Adding Copy Pairs
Execute the acpair add command, add the TFOV as a copy source/copy destination pair to the created copy group.
Using the -p option, specify the copy pair on either the Primary Storage or Secondary Storage. The ETERNUS Disk storage system and logical volume number that become the Storage Cluster pair are automatically retrieved from the specified ETERNUS Disk storage system and logical volume number, and the copy pairs for both the Primary Storage and Secondary Storage are added.
Refer to "2.7 Adding Copy Pairs" and the acpair add command for adding.
Note
The copy source and copy destination TFOV need to belong to the same TFOV group.
All copy pairs registered in the copy group need to belong to the same TFOV group.
Copy pairs that include a non-TFOV cannot be registered.
Copy pairs that include a TFOV not synchronized between the Primary Storage and Secondary Storage cannot be registered.
When registering copy pairs, do not perform a failover or a failback.
The acgetvolinfo command displays logical volume information for ETERNUS Disk storage systems where the TFO status is "Active". Even if the Primary Storage or Secondary Storage is specified using the -p option of the acpair add command, both copy pairs can be registered. Specify the ETERNUS name of the ETERNUS Disk storage system where the TFO status is "Active" and the copy source/destination logical volume numbers that are displayed with the acgetvolinfo command.
