Installing HDLM
The following section describes how to install HDLM for a new installation, for
a re-installation, and for an upgrade installation. Depending on the
procedure, the host might have to be restarted after HDLM is installed. HDLM
can also be installed by performing an unattended installation, which enables
a user to install HDLM without entering information. Select the procedure
suitable for your environment.
To create an HDLM device, the HDLM configuration definition utility
dlmcfgmgr is used. For details on the dlmcfgmgr utility, see
dlmcfgmgr Utility
for Managing the HDLM Configuration on page 7-22 .
If you want to install HDLM in a boot disk environment that uses SCSI
devices, see Installing HDLM for Managing Boot Disks on page 3-132 .
HDLM supports md devices in Red Hat Enterprise Linux AS4/ES4, Red Hat
Enterprise Linux 5, Oracle Enterprise Linux 5, and Red Hat Enterprise Linux 6
environments. If you want to perform a new installation of HDLM in an
environment where an md device has been activated, see Using HDLM in an
md Device Environment on page 3-188 .
Preparations for a New Installation of HDLM
This section describes the preparations required before newly installing
HDLM. This includes backing up devices to be managed by HDLM and setting
up the hardware and volume management software.
Operations Required for Devices to Be Managed by HDLM
If any devices to be managed by HDLM are operating, you need to perform
the following procedure.
To prepare a device that is already operating:
1
.
Terminate all processes of applications that are accessing devices to be
managed by HDLM.
2
.
If necessary, back up all devices that are to be managed by HDLM.
3
.
Unregister the devices.
If a device to be managed by HDLM is registered in a program, including
cluster software (excluding the volume management software), release
the registration.
When accessing a device that is to be managed after HDLM installation,
the setting name used until now cannot be used for access because the
logical device file name for the HDLM device that HDLM creates is used.
4
.
Unmount the disks.
