A.4 Notes on the mkfs Command

If you are going to create a file system for an HDLM device, specify the name of a
logical device file of the HDLM device for the
system is created for a SCSI device that is already in use, the applicable HDLM device
will be created with a file system even without creating a new file system by using the
command.

Furthermore, if the
confirming whether to execute the command will appear; however, when an HDLM
device is specified, the message will not appear.

A.5 Notes on the fdisk Command

You can perform operations on a partition of an HDLM device by executing the
command with the name of a logical device file of the HDLM device specified. Up to
15 partitions can be created just as for a SCSI device. In addition, by setting up
partitions in an HDLM device, partitions can be set up in a corresponding SCSI device
at the same time.
However, partitions for a device managed by HDLM will not be automatically created
at the same time even when partitions are created for a corresponding SCSI device that
HDLM manages. In this case, restart the host to make the partitions the same as those
for the corresponding SCSI device.
If HDLM is installed for the first time, an HDLM device that inherits the partitions of
the corresponding SCSI device will be created automatically.
Also, in an IPF or EM64T/AMD64 environment, if you execute the
on the HDLM device while running SUSE LINUX Enterprise Server 9 or Red Hat
Enterprise Linux AS4/ES4, an error message (KAPL05023-E) is output to the syslog
file. However, HDLM operations are not affected.
