Chapter 1 Installing Operating System
*1 The partition size actually reserved slightly differs from that shown in the table.
*2 We recommend you to save 300 to 500 MB size partition as described above because
the latest kernel security and bug fixed should be additionally installed on the /boot
partition when using the system continuously.
*3 Keep the partition size of 24GB regardless of the amount of memory installed on this
server. If its partition size is smaller than the amount of installed memory, the following
warning message may be displayed while the system starts. But it is not problem in the
system
Warning: There might not be enough space to save a vmcore.
When the partition size is less than 24GB and the amount of installed memory, the
installation of ft Sever Control Software fails.
*4 The swap partition size depends on the amount of installed memory. Calculate swap
partition size according to the table below.
*5 Free area can be used to create a partition. To add a partition, see the following section:
－ Chapter 1 (2.6 Creating Volume)
•
The disk pair of software RAID must be configured in combination of corresponding slot
numbers. The corresponding slot numbers are as follows. See the above "Note" column for
each device name.
－ Slot 0 of CPU/IO module 0 and Slot 0 of CPU/IO module 1
－ Slot 1 of CPU/IO module 0 and Slot 1 of CPU/IO module 1
－ Slot 2 of CPU/IO module 0 and Slot 2 of CPU/IO module 1
－ Slot 3 of CPU/IO module 0 and Slot 3 of CPU/IO module 1
－ Slot 4 of CPU/IO module 0 and Slot 4 of CPU/IO module 1
－ Slot 5 of CPU/IO module 0 and Slot 5 of CPU/IO module 1
－ Slot 6 of CPU/IO module 0 and Slot 6 of CPU/IO module 1
－ Slot 7 of CPU/IO module 0 and Slot 7 of CPU/IO module 1

Configure all partitions (including a swap partition) with software RAID (LEVEL=1, number
of hard disk drives=2, number of spare hard disk drives=0).

Ensure to create /var/crash partition, as ft Server Control Software requires exclusive one
for the dump.

Use fdisk or df command to view the partition information or free space of hard disk drive.

Do not place /usr on a separate partition from the rest of the root volume.

LVM feature of hard disk drive including system partition is not supported.
The size of UUID=<UUID> should be much greater than <file size> kilo bytes.
Amount of installed memory
4GB or less
Larger than 4GB 16GB or less
Larger than 16GB 64GB or less
Larger than 64GB 256GB or less
