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.
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)
SCSI device 1..n: The SCSI device names which are being managed by
the above HDLM device (for example, /dev/sda)
Notes on the vgrename and lvrename Commands
If a logical volume is created on an md device, you can rename a volume
group or a logical volume by using the vgrename or lvrename command.
After renaming, if the vgdisplay -v -D command, vgscan, or lvscan
command is executed, the information from the previous volume group or
logical volume might be displayed. To display information from after the
change, deactivate the volume group, and then activate the volume group
after restarting the md device.
