Common Causes of Disk Array "Down"

Q: What is the cause of the "disk loss" of the disk array?

A: The disk disk "off disk" is more common. Especially in the IDE disk array, this is generally caused by the following reasons

1, high temperature, poor heat dissipation, resulting in unstable control chip of the hard disk, the solution is to enhance heat dissipation, for example, add on the hard disk Mounting heat sink

2, PATA cable becomes soft, there is a problem, the cable change /SATA interface becomes soft and causes poor contact, change line

3, overload

4, the power supply is insufficient, the solution is to change the power

5, the hard disk version of the hardware does not match the RAID card, resulting in unstable array RAID information, the solution is to upgrade the hard disk Fireware

The problem of the RAID card itself, change the card
