2.4.2 Duplicating hard disk drives

Use ftdiskadm command to duplicate hard disk drives.
The following is a configuration example of duplication of hard disk drives installed in Slot 2 (Slot 1 of CPU/IO
module 0) and Slot 10 (Slot 1 of CPU/IO module 1).
1. Select [3 Make Mirroring Arrays (RAID1)] on ftdiskadm to create an arbitrary partitions in hard disk
drive specified by the Slot number. The created partition is copied to its corresponding pair disk
automatically to create duplication.

[Make Mirroring Arrays
* Which scsi SLOT? [1-16] 2 ----------------------------------------------- (*1)
Making the disk partition table: SLOT=2 SIZE=139705(MB)
Reserved for the last partition: SIZE=1024(MB)
* How many partitions? [1-14] 3 ------------------------------------------- (*2)
* Input the SIZE of partition 1
* Input the SIZE of partition 2
* Input the LABEL [1-12 character(s)]-------------------------------------- (*3)
* Are you sure to create it? [y/n] y
*1 Enter the slot number of the disk you want to configure duplication. The slot number of the pair disk
(10) is also available.
*2 Specify the number of partitions to be created.
Then specify the size for each partition by MB. The remainder is automatically allocated to the
partition with the last number. As for partition number, after 3 comes 5, followed in ascending order.
Since a certain amount of volume is reserved for the last partition, the range of values that can be
specified is smaller than that of the actual disk space. The value of actual partition volume varies
slightly depending on the disk configuration.
*3 If necessary, specify the disk volume label.
If the hard disk drive is used with a single partition, the entered value is used as a volume label. If
the hard disk drive is used with multiple partitions, "<entered value>_s<partition number>" is used
for volume label. The volume labels specified here can be modified later by commands such as
e2label.
