3. Creating an HDLM Environment
258
3.11 Settings for Xen
When HDLM is installed in an environment that uses Xen, the SCSI devices
corresponding to HDLM devices are accessible from a domainU environment.
Therefore, you must specify the certain settings so that the SCSI devices cannot be
accessed from the domainU environment directly.
The following procedure shows how to migrate SCSI device
/dev/sda
, which is
connected in the domainU environment in a single-path configuration, to HDLM
device
/dev/sddlmaa
, which is connected in a multi-path configuration.
1. Check the correspondence between the HDLM and SCSI devices.
Execute the HDLM configuration definition utility (
dlmcfgmgr
) with the
-v
parameter.
# /sbin/dlmcfgmgr -v
HDevName Management Device Host Channel Target Lun
/dev/sddlmaa configured /dev/sda 2 0 0 0
/dev/sddlmab configured /dev/sdb 2 0 0 1
:
:
KAPL10302-I /sbin/dlmcfgmgr completed normally.
#
HDLM devices are listed in the
HDevName
column, and SCSI devices are listed
in the
Device
column.
2. Check whether the SCSI devices can be migrated to the HDLM devices.
Execute the command shown below.
In the following example, the
domU
configuration information is retrieved from
the management domain:
# /usr/sbin/xm list -l domU
