Assign a name and operating system profile to the connection (the additional HBA
connected to the second MSA array controller).
From the CLI, enter add connection <name> WWPN=<WWPN> profile=<type>
Example display, assigning a connection name of HBA2:
CLI>add connection HBA2 WWPN=50060B00-00225CB0 profile=hp
Connection has been added successfully. Profile hp is set to the
new connection.

Verify the connection.
From the CLI, enter show connections
Example display:
CLI>show connections
Connection Name: HBA1
Host WWNN=20000000-C93673BA
Host WWPN=10000000-C93673BA
Profile Name=hp
Connection Name: HBA2
Host WWNN=50060B00-00225CB1
Host WWPN=50060B00-00225CB0
Profile Name=hp
NOTE: As highlighted in the example, the connection to the second controller now
has a defined connection name and operating system profile type.

Grant the new controller access to the storage.
From the CLI, enter add acl connection=<connection_name> unit=<LUNs>
Example display, granting connection HBA2 access to LUNs 0, 1, and 2:
CLI>add acl connection=HBA2 unit=0 1 2
Enabling ACL. Allowing 50060B00-00225CB0 access to unit 0 1 2.

Verify the changes to the access control list.
From the CLI, enter show acl
Example display:
CLI>show acl
Connection WWPN Units
HBA1 10000000-C93673BA 0, 1, 2
HBA2 50060B00-00225CB0 0, 1, 2
