Table 7 O/S disk activity and status LEDs
LEDs
Meaning
Blue
If this LED is on and blue, the disk is operating normally and no
problems have been detected. If the LED is flashing blue, this
indicates disk activity. If the LED is on but not flashing, there is
currently no disk activity.
Red
If this LED is on immediately after installing a new O/S disk, this
indicates that the RAID configuration for the server is being rebuilt.
The LED turns 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 O/S disk), either the disk has failed or the server’s
RAID configuration has been degraded.
O/S drives
O/S drives are located behind the bezel on the left side of the chassis.
Note:
■
Failed O/S drives are hot-swappable, which means that a failed drive can
be replaced without shutting down the server. However, there are serious
risks in trying to swap a drive that has not failed. It is strongly
recommended that you avoid performing replacement procedures during
busy periods to minimize the risk of any disruption caused by the
procedure.
■
Do not attempt to replace or recover a O/S drive without the assistance of
Hitachi Vantara Customer Support.
The O/S drive A and B status and activity status LEDs of the 5200 and 5300 server models
