IBM System Storage DS6000 Series: Copy Services with IBM System z
Clearly, you should change the IP address to match the one used by your SMC. If you are
actually working on the SMC PC itself, you can also use 127.0.0.1 since this is the loopback
address that connects to the local PC.
Logging in to the DS Storage Manager requires that you provide your user ID and password.
This function is generally administered through your system administrator and by your
company policies. The preconfigured user ID and password are as follows:
򐂰 User ID: admin
򐂰 Password: admin
When you log on to the SMC for the first time using the
admin
user ID, you must change the
password from
admin
to something more secure.
3.3.1 Real-time and simulated configuration
You have the following options to access the DS Storage Manager:
򐂰 Simulated (offline) manager
This application allows you to create or modify logical configurations when disconnected
from the network. After creating an initial configuration, you can save it and then apply it to
a new or unconfigured Storage Unit at a later time. However, you cannot use the
Simulated manager to perform any type of Copy Services configuration. You must perform
Copy Services configuration from the Real-time manager.
򐂰 Real-time (online) manager
This provides real-time management support for logical configuration and Copy Services
functions to a DS6000 Storage Unit.

simple Web browser pointed to the DS SMC is enough.
3.3.3 Disadvantages of using the DS GUI over the DS CLI or TSO

and Copy functions:
򐂰
You cannot perform all supported functions from this interface.
򐂰

need to understand that a FlashCopy overwrites the target LUN or volume).
