7. Handling of the Disk Array Unit
This chapter describes how to handle the disk array unit.
7.1 Notes on Handling of Disk Array Unit
Note the following regarding the following in use of the disk array unit. Incorrect handling of the disk
array unit may cause the unit to become defective and/or data corruption.
„ If the ACCESS LED (green) on the controller lights or flashes, or a disk access
operation is indicated at the host system, or the disk array initialization is being
executed, do not turn on/off the disk array unit or host system power. Do not reset the
host systems.
„ If the ACCESS LED (green) on the controller lights or flashes or disk access
operation is indicated at the host system, do not apply vibrations and/or shock to the
disk array unit.
„ Because the disk array unit is a precision device, it should not be subject to any hard
vibration or shock.
The reliability features of the disk array unit are effective only in the case of a hardware
failure (e.g., the hard disk becomes physically damaged or inoperative). Any software
failure (e.g., the data is lost or rewritten due to program excursion) is not covered by
these features. Should a software failure occur, the system/data could be seriously
damaged. To minimize this damage, be sure to back up your data regularly.
It is recommended that important files are backed up regularly. This enables the damage
to be minimized in the case of an emergency including sudden vibration/shock or a
power shutdown caused by any power interruption.
