Chapter 29. Interoperability between DS6000 and ESS 800 435
If he ESS 800 is going to be purely a remote target for PPRC, and you do not plan to use
it as a source server or use DS GUI to manage the pairs and paths, then you do not need
to have network connectivity to the ESS 800 Copy Services servers. This is because all
path and pair establishment is done by connecting to the source server (which would be
the DS6000). This setup is not recommended because it is less flexible.
29.2.4 Creating matching user IDs and passwords
When you want to use the DS CLI or DS GUI to perform Copy Services operations, you need
to authenticate with a valid user ID and password. When you use the DS GUI to perform an
operation requires it to issue a command to an ESS 800, it must authenticate with the ESS
800. To do this, it uses the DS user ID and password that you used to log on to the GUI. This
means that this user ID and password must be defined in the ESS Specialist. This task needs
to be manually performed. If instead of the DS GUI, you only use the DS CLI, then you are
logging on to the ESS 800 Copy Services server directly and the DS user ID and password
for the GUI is not necessary. For simplified management, you can still create a matching user
ID and password.
Creating a user ID on the DS6000
Log on to the DS6000 SMC using the DS GUI and create a user ID that is in either the admin,
op_storage. or op_copy_services groups. Log off and then log on with that user ID and
change the initial password.
Creating a user ID on the ESS 800
Once you have created a DS user ID, you must create a matching user ID using the ESS 800
Web Specialist:
1. Start a Web browser and connect to the IP address of either ESS 800 cluster.
2. Click
ESS Specialist.
3. Log on with a ESS Specialist user ID that has administrator privileges.
4. Click
Users.
5. Click
Modify Users. Type the user ID name and password that you created in the DS CLI
or GUI. It must be given the
Administration access level.
6. Click
Add to move the user ID to the right hand box.
7. Click
Perform Configuration Update and wait for the completion message.
29.2.5 Updating the DS CLI profile
If you plan to use the DS CLI to manage your ESS 800, you can create a profile to simplify:
connection, commands, and scripted operations. Add extra lines as shown in Example 29-1.
Example 29-1 Possible modification to a DS CLI profile
# ESS 800
# SMC1 is the Copy Services server A
SMC1: 10.0.0.100
# devid is the serial number of the ESS 800 - note there are only 5 digits after the 2105
devid: IBM.2105-22399
# remotedevid is the serial number of the DS6000
remotedevid: IBM.1750-1300247
Important: The ESS Web Copy Services user IDs are not used by the DS CLI or DS GUI.
You only need to create a matching ESS Specialist user ID.
