Creating the SAN Database
About the Database
The SAN Manager LM database stores important information such as administration
groups, device assignments, and customized device information.
To ensure reliability, the database design takes advantage of disk mirroring. By using a
mirrored database, SAN Manager LM writes database information to multiple devices
simultaneously, but reads from just one. If the active database device goes offline, another
device from the mirror set takes over. With a three-device mirror set, you can experience
two disk failures and the SAN will continue to run uninterrupted.
The database must be created on a mirror set composed of up to three SAN devices that
are partitioned with SAN Manager LM’s Universal Partition Map (UPM) format. Devices
with any other type of partition map cannot be used for the database.
For more information about the UPM partitioning format, see page 137.
Creating the Database
Before you can create a database and begin using the SAN, you must prepare up to three
database devices by partitioning them in SAN Manager LM and creating a mirror set.
1. On any SAN Manager LM host that has the administration application installed, log on
to the network as a member of the domain administrators group.
Note You must be a domain administrator to set up SAN Manager LM during the
initial configuration procedure. If your network does not have a Windows NT
domain, log on to the network as a member of the host’s local administrators
group.
2. From the Start menu, select Programs  SAN Manager LM.
