Hard Disk Drives - Hitachi 3090 G2 Hardware Reference Manual

Hard disk drives

The server contains two hard disks, which are configured as a Linux SW RAID 1 pair, and
they store server or cluster-related data. These hard disks are not part of the customer-
usable data storage that is available to the server.
Hard disks are located behind the bezel on the left side of the chassis.
Note: Failed hard disks are hot-swappable, so a failed hard disk can be
replaced without shutting down the server. However, there are serious risks
in trying to swap a drive that is not failed.

Table 8 Hard disk activity and status LEDs
If this LED is on and blue, the disk is operating normally and no
problems have been detected. If the LED is flashing blue, it indicates
disk activity. If the LED is on, but not flashing, there is currently no
disk activity.
If this LED is on immediately after installing a new hard disk, it
indicates that the RAID configuration for the server is being rebuilt.
The LED will turn off after the RAID configuration is restored. The
amount of time it takes for the RAID configuration to be rebuilt after a
new disk drive is installed depends on the amount of user and system
configuration data stored.
If this LED is on during the course of normal operation (not after
installing a new hard disk), either the disk has failed or the server's
RAID configuration has been degraded.
