2. Repeat the procedure for all the drives to configure them as multipath drives.

Note: If you switch between the first and second configuration options, you need to configure the
same device twice from two different Cell Managers. You should delete one device from CM2
and just keep the device from CM1. You will have to change the “Destination” for the backups
configured using the deleted device. You can either do this from the GUI or by editing the
datalists/barlists located on the Cell Manager with a text editor.
Using sanconf
Sanconf is a utility for auto-configuring and modifying libraries and drives in a SAN. It allows the
following tasks to be performed:
Scanning specified Data Protector clients, gathering information on SCSI addresses of drives
and robotic controls connected to clients in the SAN environment.
Configuring or modifying settings of a library or drive for given clients using the information
gathered during the scan of Data Protector clients.
Removing drives on all or specified clients from a library.
In Data Protector 6.1, this utility was limited to work only within a single cell, with no option to be
used in a MoM environment.
In Data Protector 6.11, sanconf has a new sanconf –mom –existing options option from the
MoM server. Sanconf is able to configure any device from any cell that uses the same CMMDB as
the cell in which sanconf is started.
The following limitations apply:
All cells have to use a CMMDB. Cells that use their own MMDB (even if they are part of the
same MoM) cannot be configured in this way. You must run a separate sanconf for such cells.
If one MA client is configured in more than one Cell Manager, only the first Cell Manager will
be shown during configuration. This will be visible in messages and debugs only; it has no
impact on the functionality.
In environments where security settings do not allow connections across Cell Managers, the
functionality will not work. Clients from cells using a CMMDB will have to be configured in a
way to allow sanconf from another cell to contact them directly. This is valid for firewall settings
and for Data Protector Permission settings.
