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 are shown as follows:

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, it 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, 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 O/S disk), either the disk has failed or the server’s RAID configuration has been degraded.
