When a slow disk is replaced, one disk controller is OUT and first processed. The other controller is GOOD and has the slow disk mark, triggering the slow disk processing process. Therefore, the disk PHY is closed. However, the driver enables disk PHY when the disk is removed. If the operation of closing the disk PHY occurs after the driver enabling it, the newly inserted disk can be recognized by only one controller or cannot be accessed.
1. Decompress the log file and find the event folder. Open it and view the event information as shown in the following figure. Confirm that the disk has slow response.
2. View the SES
log information for the command output of disable disk phy
The command output shows that the disk PHY is closed when the disk is removed.
3. View the messages
log to determine whether the slow disk processing is implemented.
The log shows that the slow disk processing is implemented when the disk is removed. The RAID mechanism closes the disk PHY.
