Figure 3-97 on page 152. Complete the connection information for the storage system.
The following sections show the Connection page for DS8000, SAN Volume Controller, and
XIV systems. The fields are the same on the Connection pages for SAN Volume Controller
Storwize Family, and Storwize V7000 Unified storage systems.
3.13.1 DS8000 Connection page
You must use a Hardware Management Console (HMC) connection to connect to a DS8000
storage system if the system is a DS8700 or later or is on an Internet Protocol version 6
(IPv6) network.
If the storage system is earlier than DS8700 and is on an Internet Protocol version 4 (IPv4)
network, you can connect to the system directly.
Setting up an HMC connection
Click HMC and complete the connection information for the primary and optional secondary
HMC, as shown in Figure 3-97 on page 152. A secondary HMC is used for redundancy. Both
HMCs must be configured identically and must have the same user name and password.
Note: A dual HMC (primary and secondary HMC) while optional is highly recommended
for redundancy purposes when Tivoli Storage Productivity Center for Replication is used.
