The server Commands
[primary=<ip_address>][config=<pathname>]
The primary option designates the local Usermapper service as
secondary by indicating which primary service it depends on. The
primary Usermapper is identified by its network IP address.
The config option indicates that the Usermapper service should use
an existing Usermapper configuration file to define UID/GID ranges.
This option is only relevant if you are upgrading from External to
Internal Usermapper.
Note: If there is no specific reason to use particular UID and GID ranges for
your environments' domains, EMC encourages you to use the automatic
mapping method and let Internal Usermapper automatically assign new
UIDs/GIDs based on the next available values. If you need to use an existing
Usermapper configuration file, you must specify the config option during
the upgrade procedure, that is, before Internal Usermapper has begun
issuing default UIDs and GIDs.
-disable
Disables the Usermapper service.
-remove -all
Removes all entries from the Usermapper databases and destroys the
database structure. The Usermapper service must be disabled before
you can issue this option.
CAUTION
!
EMC recommends that you consult with Customer Support before
issuing the -remove -all option. This option deletes all Usermapper
database entries and may result in users losing access to file
systems. If you decide to use the -remove -all option, you should
first back up your existing Usermapper database file and
usrmap.cfg file (if one is in use).
-Import {-user | -group} [-force] <pathname>
Imports Usermapper database information from the file specified by
<pathname>.
By default, only new entries are added to the Usermapper database.
If an entry in the imported file does not match a similar entry in the
existing database, the entry in the imported file is ignored unless the
-force option is selected. If -force is selected, the existing database is
deleted and replaced with new entries.
