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.
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).
You can also perform installation when HDLM is started. For details, see The
installhdlm Utility for Installing HDLM on page 7-33 or installux.sh Utility for
HDLM Common Installer on page 7-44 .
