3.5 Installing HDLM

When you install HDLM, Hitachi Network Objectplaza Trace Library (HNTRLib2)

will also be installed.
The file path of the integrated trace information file of Hitachi Network Objectplaza

Trace Library (HNTRLib2) is

/var/opt/hitachi/HNTRLib2/spool/

hntr2

.log

(n indicates a file number).

3.5.1 Preparations for a New Installation of HDLM

This section explains how to apply patches to Solaris, back up HDLM-managed

devices, set up hardware, and set up volume management software.

(1) Performing Operations on 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 the processes of all applications that access the device to be managed

by HDLM.

If necessary, back up the contents of the device to tape.

Collect all relevant information about the logical device file names of the device,

and internal LUNs of the LUs in the storage system. This is so that you can keep

the correspondence with the logical device file names once installation is

complete.

When you execute the

dlmsetconf

utility for creating the HDLM driver

configuration definition file, and restart the host with the reconfiguration option

specified, the logical device files of the sd or ssd devices to be managed by

HDLM will be deleted. Back up all pertaining to the logical device files under the

/dev/dsk

and

/dev/rdsk

directories to another directory.

The following shows an example of executing the commands:

# mkdir /var/tmp/bkfile1
# ls -l /dev/dsk > /var/tmp/bkfile1/devices1
# ls -l /dev/rdsk > /var/tmp/bkfile1/devices2

Unregister the device.
If the device is registered with any cluster software program applications (other

than Volume Manager), unregister it. Since HDLM devices are accessed with the

logical device file names assigned by HDLM, these applications will no longer be

able to access such devices using the logical device file names currently used.
