DISK OPERATIONS

NEC Express5800/ft series duplicates disks to secure data integrity by Software-RAID. This section
describes how to replace a disk.
IMPORTANT:
It is recommended to create only a system partition on the disks with OS.
When you create a partition other than a system partition on the disk with the OS, note the
following:
If you reinstall the OS, the entire disk will be cleared. If there is any data partition other than the
system partition, the data must be backed up before reinstalling the OS.

Operable disk configuration

RAID must be configured for all the internal disks in NEC Express5800/ft series.
