Configuring An Existing System Device To Use Evms - Novell LINUX ENTERPRISE SERVER 10 SP3 - STORAGE ADMINISTRATION GUIDE 2-23-2010 Administration Manual

NOTE: Effective in SUSE Linux Enterprise 10, the
nodes are automatically re-created on boot. It is no longer necessary to modify the
init.d/boot.evms
previous versions of SUSE Linux.
5 Continue with
Restart the Server
1 Restart the server to apply the post-install configuration settings.
2 On restart, if the system device does not appear, it might be because EVMS has not been
activated. At the prompt, enter
evms_activate

After the post-install configuration is complete and you have restarted the server, make sure the
server is operating as expected.
2.2 Configuring an Existing System Device to
Use EVMS
If you have already installed Linux with a different volume manager for the system device (that is,
the devices where you installed the
configure the device for EVMS at any time after the install.
If you do not configure the device to use EVMS, you must manage the device and all of its volumes
with its current volume manager (the default is LVM), and free space on the device cannot be used
for volumes you want to create using EVMS. Beginning with the Linux 2.6 kernel, a given device
cannot be managed by multiple volume managers. However, you can have different volume
managers for different devices.
The following procedures assume that you installed Linux with three partitions on a single SCSI
device named
/dev/sda1
/dev/sda2
/dev/sda3
IMPORTANT: Make sure to modify the following procedures as necessary for your specific setup.
