A.6 Notes on the sar Command
Executing the
sar
command with the
-d
or
-A
option does not display HDLM
devices. To obtain statistics about an HDLM device, perform calculations by using the
value of the SCSI device that conforms to the HDLM device. The following is an
example of executing the
sar
command.

A.7 Notes on the fdisk and parted Commands
When creating partitions on an HDLM device, only use the
fdisk
command or the
parted
command.
If partitions have been created on an HDLM device using the
fdisk
or
parted
command, some of the partitions created by the
fdisk
command might not be visible
to the
parted
command. Likewise, some of the partitions created by the
parted
command might not be visible to the
fdisk
command. For this reason, if partitions
that are created using the
fdisk
command are modified using the
parted
command,
the partition information might be corrupt.
A.8 Notes on the parted Command
If the
parted
command is used to create partitions on an HDLM device, after issuing
the
parted
command, execute the following command:
# blockdev --rereadpt
HDLM device SCSI device
1 ...
SCSI device n
Where:
HDLM device: The HDLM device name on which the partition was created (for
example, /dev/sddlmad)
