Two Dell server troubleshooting examples

Fault Diagnosis for automatic shutdown of Dell servers

Fault description: The Dell server suddenly shuts down automatically. There is no error code and cannot be restarted.

Fault diagnosis:

1. Power outlet. Due to the high power of the server, the General Plug-In cannot withstand large currents for a long time. When the temperature increases, the electric shock may lead to poor contact or disconnection. Change the dedicated plug-in or PDU of the server.

2. Poor heat dissipation. After several years of operation, the server should regularly remove dust and maintain the fan.

3. Poor Board contact. If the Board has poor contact, the server will be automatically shut down without any warning and cannot be restarted. Generally, you can hear this sound before the server is automatically shut down. You must power up after the power is completely cut off before it can be started. This indicates that the board is loose and causes circuit protection. Check and fix the expansion board.

4. Power backboard faults. The performance of the power supply circuit decreases, causing the server to automatically shut down.

Troubleshooting of dell 2850 server hard drive

Troubleshooting of server hard disk faults

Configuration Overview:

1. Four hard disks are used as RAID 5.

2. 2003 Operating System

Fault status:

Among them, the hard drive of the No. 0 plug-in has a yellow light. The first re-plugging fault is solved, and the same situation has occurred in a few days.

Solution:

Condition: the system must be online (in 2003 Status) for hot swapping.

1. Insert an existing hard disk into the disk, but the old hard disk has partition and display information. You need to find an empty server for initialization, instead of initializing the existing server to avoid damaging the entire display information,
All data is lost.

2. Take a new hard disk and replace the bad hard disk online. The hard disk will automatically synchronize its own information and load it into the display information, which is called rebuilding.
