4-28 Linux Setup
IMPORTANT:
When a disk is added or RAID is reconfigured, the status of each disk becomes
"RESYNC", "RECOVERY", "CHECK" or "REPAIR". When a disk is in this status,
do not insert or remove the disk, power off, or restart the system. Wait until the status
is turned to "DUPLEX". Check to see the status of each RAID device using the
after-mentioned ftdiskadm command. See "Verifying duplication" on page "4-30".
Use only the hard disk drives specified by NEC. If you install a third party product, not
only the hard disk drive, but also the entire device may fail. Purchase a pair of two hard
disks of the same model. Consult your sales agent for which ones are the best suitable.
The actual operation (e.g. mounting a disk) for a built-in disk is performed for the device (md) for
RAID by software.
In ftdiskadm described later, slot numbers of the built-in disks are allocated as shown below to use.
Disk slot number for H/W
PCI module 0 Slot 1
PCI module 0 Slot 2
PCI module 0 Slot 3
PCI module 1 Slot 1
PCI module 1 Slot 2
PCI module 1 Slot 3
Use ftdiskadm for checking the disk information.
The following is a display sample when you execute ftdiskadm, enter 2 for [RAID] and then 2 for
[Status(System Disks)] (for displaying information on built-in disk).
