Complete this task to create a storage complex domain by establishing
a connection with a secondary management console (peer) for redundancy.
You can install a secondary management console (MC) for
backup purposes. It is especially important if you use DS Copy Services. You
install the secondary MC the same way that you installed the primary MC.
After the primary and secondary MCs are installed, perform this process
from the primary MC. You must have the MC IP address and the appropriate user
ID and password. To establish a peer-to-peer relationship, both user IDs and
passwords must be the same for the primary and secondary MCs.
When you
add a secondary MC, the secondary MC cannot have storage units that are associated
with it. If you have two MCs that each have storage units that are associated
with them, you must remove the storage units from the secondary MC that you
want to use as the peer of the primary MC. After you remove the storage units,
add the secondary MC to the primary MC. You can then add the previously removed
storage units using either the primary or the secondary MC.
You
must have the same administrator password set for both MCs before you can
define multiple management consoles.
Perform the following steps to establish a connection with a secondary
MC for the storage complex that is associated with the primary MC.
Note: When
you use peer MCs, if one of the consoles fails, you cannot make changes to
any user accounts. If the peer-to-peer relationship cannot be restored, you
must remove the secondary MC using the Removing Peer Management Consoles function,
using the primary MC.
- In the navigation, select . On the Storage complexes – Main page, select a storage complex.
- From the Select Action menu, select Define
peer, and then click Go.
The Define peer management console page is displayed.
- Perform one of the following steps, but not both:
- Specify the server host name for the secondary MC.
- Specify the server IP address for the secondary MC.
- Click OK. The storage complex domain is
established.
- Open a command prompt and navigate to the C:\Program Files\IBM\dsniserver\bin\
directory where the recovery tool (script) has been installed.
- Type the script name, securityRecoveryUtility.bat -s
Note: This utility synchronizes all of the user account information
between the primary and secondary MCs. After the user accounts have been synchronized,
all changes to user accounts are automatically reflected on both peer MCs
unless the peer-to-peer relationship is broken. If you remove a peer, and
define a new peer, you must run the recovery tool script again after you determine
the new peer.
Click on the Storage Complexes main page and
you should see a second MC nickname that is defined with status on the right-most
column.
