Registering SVC and Storwize storage devices

For IBM® SAN Volume Controller (SVC) storage system and Storwize® storage system, the storage agent uses specific storage scripts and their corresponding interfaces to interact with the storage devices. When you add a storage agent to the KSYS subsystem, you must specify the cluster ID, storage login user name, and the IP address of the storage subsystem.

You can use the SVC or Storwize GUI or the following command to get the cluster ID of storage disks:

ssh usrid@ipaddr svcinfo lscluster

To add the storage agents in the GDR solution, complete the following steps in the KSYS LPAR:

Add the storage agent (for example, name: Site1_storage1, user name: abc, cluster ID: 007, IP address: 10.xx.yy.zz) to the active site by running the following command:
```
ksysmgr add storage_agent Site1_storage1 login=abc site=Site1 
clusterid=007 storagetype=svc ip=10.xx.yy.zz
```
Note: The value of the storagetype attribute must be svc for both the SVC system and the Storwize system.
Add the storage agent (for example, name: Site2_storage1, user name: abc, cluster ID: 008, IP address: 10.xx.yy.zz) to the backup site by running the following command:
```
ksysmgr add storage_agent Site1_storage1 login=abc site=Site2 
clusterid=008 storagetype=svc ip=10.xx.yy.zz
```

Optional: Verify the storage agents that you added by running the following command:

ksysmgr query storage_agent

An output that is similar to the following example is displayed:

Name:            Site2_storage1
Clusterid:       008
Storagetype:     SVC
Site:            Site2
Ip:              10.xx.yy.zz
Login:           abc

Name:            Site1_storage1
Clusterid:    007
Storagetype:     SVC
Site:            Site1
Ip:              10.xx.yy.zz
Login:           abc
