Notes on Command Execution

When HDLM is used, you cannot specify the -r option in the drvconfig,
devlinks, disks, or devfsadm command to reconfigure the HDLM devices on
another boot disk. To reconfigure HDLM devices, you must boot them from
the applicable boot disk.

Notes on the Disk Label

Before changing a disk to be managed by HDLM to an HDLM-managed disk,
make sure that you execute the format command to add a VTOC label or EFI
label to the disk. If you attempt to use HDLM to manage a disk that does not
have such a label, the path will not come online.

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/hntr2n.log (n indicates a file number).

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.

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.
2 If necessary, back up the contents of the device to tape.
.
3 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.
4 When you execute the dlmsetconf utility for creating the HDLM driver
.
configuration definition file, and restart the host with the reconfiguration
You can use zoning of Fibre Channel switches or storage-system's
WWN security function to separately use HBA ports. You can also use
point-to-point connections to physically separate the HBA ports.
