HARD DISK CONFIGURATIONS THAT CAN BE BUILT
ON THE NEC Express5800/ft series
In the NEC Express5800/ft series, all built-in disks need RAID configuration. Configure
RAID 1 using software for the NEC Express5800/ft series.
The hard disks on the same slot location of the PCI module configure RAID. As shown in
the following figure, hard disk drives in Slot 0 and Slot 3, Slot 1 and Slot 4, Slot 2 and Slot
5 should be paired to configure RAID.
Slots to execute the mirroring process
IMPORTANT:
When adding disks or reconfiguring RAID, the status of each disk becomes "resync" or
"recovery." Do not insert/remove disks, turn off the power, or restart the system during
this status. Wait until the status of "resync" or "recovery" is finished. You can check
the status of RAID using ftdiskadm described later. For details, see the separate volume
of User's Guide (Setup).
Two hard disk drives which configure RAID 1 must have the same disk capacity. Also,
two hard disk drives must have the same logical structure.
Perform operations for built-in SCSI disks, such as mounting a disk, to devices (md) for
RAID by software.
With the standard configuration at the time of shipment, the boot disks are inserted to the
Slot 0 and Slot 3.
