3.23.5 Canceling the Settings for VCS
This section describes how to cancel the HDLM device settings in VCS in an
environment where VCS is used. For details on how to perform operations from the
VCS GUI, see the VCS documentation.
To cancel the HDLM settings in an environment where VCS is used:
1.
Stop the cluster service of VCS.
2. Change the HDLM device used by VCS to a SCSI device.
Change the
Block Devices
parameter in
Mount
resource from an HDLM
device to SCSI device.
3.23.6 Canceling the Xen Settings
This subsection describes how to cancel the HDLM device settings in an environment
in which Xen is being used.
The following is the procedure for migrating a domainU environment that uses the
HDLM device
/dev/sddlmaa
in a multi-path configuration to an environment that
uses the SCSI device
/dev/sda
in a single-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
- 2 0 1 0
/dev/sddlmab configured /dev/sdb 2 0 0 1
:
:
KAPL10302-I /sbin/dlmcfgmgr completed normally.
#
The HDLM devices are listed in the
HDevName
column, and the SCSI devices are
listed in the
Device
column.
2. Check whether the HDLM devices can be migrated to the SCSI devices.
Execute the command shown below.
