172 Replacing a Windows NT Domain
Replacing a Windows NT Domain
Note If you have a local group from a host included in your list of SAN Administration
groups, you do not need to use the following procedure when replacing a
domain. After replacing the domain, if you have a local SAN Administration
group, run the SAN Manager LM administration application on the host with the
local group. Choose administration groups from the new domain and remove
administration groups from the old domain.
If one Windows NT domain is replaced with another, either intentionally or due to a failure
of all domain controllers, and a previous SAN Manager LM database is found at startup,
SAN Manager LM will not run until a new database is created. This is because the database
contains only administration groups from the old domain and these groups no longer exist.
If possible, complete steps 1 and 2 before replacing the domain:
1. In the case of a domain controller failure, locate a backup database file, if available. If
you are intentionally replacing a domain, follow the database backup and deletion
procedure below:
a. Click the Backup Database button or choose Database  Backup Database to
File. Save the backup file as described in the on-screen instructions.
b. Choose Database  Create New Database.
c. When SAN Manager LM asks if you want to delete the existing database, click Yes.
d. When SAN Manager LM asks if you want to use the database wizard, click Yes or No.
e. Click Exit in the database wizard or Close in the New Database dialog box.
f. Click Yes to confirm that you want to cancel the database creation procedure.
g. SAN Manager LM will notify you that no database has been found and ask if you want
to create one. Click No.
h. When SAN Manager LM asks you to confirm that you want to exit the application,
click Yes.
