Step 10: Create Volume

If there is free disk space in the internal disk with the OS, you can create a volume. To create a
volume in the free disk space and construct RAID partition,, follow the steps below.
IMPORTANT:
Ask maintenance service provider having expertise to perform the following operation.
The following operation must be performed by root user.
Check the device name of the internal disk with OS by selecting [RAID] and [Status
1.
(RAID1)] in ftdiskadm (See page 4-26).
The following example shows that the internal disks with OS are set in slots 1 (slot 1 of
CPU/IO module 0) and 4 (slot 1 of CPU/IO module 1), whose device names are /dev/sda
and /dev/sdd, respectively.
Example)
[List RAID Arrays]
Name Partition
=====================================================================
< Mirroring Array (RAID1)
md0 /boot
md1 swap
md2 /
md3 /var/crash
Create additional partition in the free disk space in slots 1 (slot 1 of CPU/IO module 0)
2.
and 4 (slot 1 of CPU/IO module 1) with the fdisk command.
In the procedures below, a partition with 1024MB is added in the free disk space in slot 1
(slot 1 of CPU/IO module 0).
Example)
<<< Start fdisk and enter command "p" to check the partition status.>>>
# fdisk /dev/sda
Command (m for help): p
Disk /dev/sda: 73.2 GB, 73200476160 bytes
255 heads, 63 sectors/track, 8899 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

<<< Create additional partition (/dev/sda4) by the command "n", and
