Configuring Lvm Devices To Use Evms; Using Evms With Iscsi Volumes - Novell LINUX ENTERPRISE SERVER 10 - STORAGE ADMINISTRATION GUIDE 7-2007 Administration Manual

You should see the following devices mounted (with your own partition names, of course)
under the /dev/evms directory:
/dev/evms/sda1
/dev/evms/sda2
/dev/evms/sda3

2.3 Configuring LVM Devices to Use EVMS

Use the following post-installation procedure to configure data devices (not system devices) to be
managed by EVMS. If you need to configure an existing system device for EVMS, see
"Configuring an Existing System Device to Use EVMS," on page
1 In a terminal console, run the EVMSGUI by entering the following as the root user or
equivalent:
evmsgui
2 In the Volumes panel, review the names that EVMS reports as compatibility volumes, find the
devices that represent the devices you want to manage using EVMS, then write down the
names for future reference.
For example, /dev/sdb1.
3 In a text editor, edit the /etc/fstab file to use the EVMS volume names.
For example, change the following entry for an LVM2 volume from this
/dev/sdb1 / reiserfs defaults 1 2
to this
/dev/evms/lvm2/sdb1 / reiserfs defaults 1 2
IMPORTANT: Make sure not to leave any stray characters or spaces in the line.
With these changes, each time your system boots, your file system is mounted using EVMS as
the volume manager.
4 Update the boot scripts as follows:
The command evms_activate must be run from your boot scripts in order to activate
your volumes so they can be mounted.
If you run software-RAID (boot.md) or LVM (boot.lvm) boot files in your boot
scripts, and if you are moving all devices to EVMS, remove or disable those commands.
5 If you have not already done so, enable the boot.evms service.
For information, see
6 Restart your system.

2.4 Using EVMS with iSCSI Volumes

If your EVMS devices, RAIDs, and volumes use storage devices from an iSCSI SAN, make sure
that your system starts iSCSI before EVMS so that the SAN and its disks are available to EVMS on
system startup. iSCSI must be started and running before any disks or volumes on the iSCSI SAN
can be accessed. If EVMS starts before iSCSI, EVMS cannot see or access the devices in the iSCSI
SAN to mount the storage objects they contain, so the EVMS devices, RAIDs, and volumes might
not be visible or accessible.
