3. Creating an HDLM Environment

3.10 Settings for LVM2
This section describes the procedure for setting the following items in an LVM2
environment:
When using an HDLM device to create a new logical volume
When moving a logical volume created on a SCSI device in a single-path
environment, to an HDLM device
When using HDLM in an LVM2 environment, use the HDLM device as an LVM2
physical volume.
3.10.1 Notes on Using LVM2
The following are notes on using LVM2:
If a logical volume on an HDLM device (LVM2) is used as the boot disk, a SCSI
device cannot be used as an LVM2 physical volume.
To use a SCSI device and an HDLM device concurrently as LVM2 physical
volumes, edit the
/etc/lvm/lvm.conf file so that SCSI devices, which are
managed by HDLM, are not recognized by LVM2.
The following shows an editing example when both a SCSI device (
/dev/sda)
and an HDLM device are used as LVM2 physical volumes.
filter = [ "a|sddlm[a-p][a-p].*|", "a|/dev/sda[1-9].*|"
,
"r|/dev/sd|" ]
In the above filter line, the underlined portion enables LVM2 to recognize
SCSI devices.
In this example, the following
filter line is used in the /etc/lvm/lvm.conf
file so that LVM2 does not recognize SCSI devices:
filter = [ "a|sddlm[a-p][a-p].*|", "r|/dev/sd|" ]
When SUSE LINUX Enterprise Server 9 is used, LVM2 cannot be used together
with Heartbeat.
