Embodiment 1

[0025] combined with figure 1 , a kind of method of testing RAID card rebuild and hot standby function by simulating faulty hard disk of the present invention, the concrete flow process of this method is:

[0026] Step S101: forming a RAID and installing the system to be tested;

[0027] Step S102: Turn on the machine to be tested, install the RAID card driver and the RAID card management tool, restart the machine to be tested, run the stress script, and monitor the data flow per second on the hard disk;

[0028] Step S103: use the command of the RAID card management tool to simulate a hard disk failure;

[0029] Step S104: performing a hot swap operation;

[0030] Step S105: Check the test result and save the RAID card log.

[0031] In step S101, RAID1 or RAID5 can be established.

[0032] In step S103, it should be ensured that the system under test operates normally and data read and write is normal when a hard disk failure occurs.

[0033] In step S104, a new hard dis...

Abstract

The invention provides a method for testing rebuild and hot backup functions of RAID cards through simulating faulted hard disks. The method comprises the specific processes of: I) building an RAID and installing a to-be-tested system; II) starting a to-be-tested machine, installing an RAID card drive and an RAID card management tool, and monitoring data traffic on a hard disk in each second after the to-be-tested machine is restarted; III) simulating a hard disk fault by using a command of the RAID card management tool; IV) carrying out a hot plug operation; and V) checking a test result and storing an RAID card log. According to the method, test is carried out rebuild, hot plug and hot backup functions through simulating faulted hard disk phenomena at customer sites, so that the test more accords with the application environments at the customer sites, the test result more accords with the requirements and various functions can be verified more effectively.

Description

technical field [0001] The invention relates to computer technology, in particular to a method for testing the rebuild and hot backup functions of a RAID card by simulating a faulty hard disk. Background technique [0002] Hard disks account for a relatively high proportion of defects in server post-maintenance. For servers, functions such as hot swapping, rebuilding, and hot backup of hard disks are all basic operations for server maintenance. This requires more targeted testing of hard disk hot swap, rebuild, and hot backup functions during the early server development process. [0003] As a key component in the server, the RAID (Redundant Array of Independent Disk) card can effectively protect the user's data security. But if the RAID card itself cannot work stably, data security will be out of the question. [0004] Based on the above statements, a method for testing RAID card rebuild and hot spare functions by simulating a faulty hard disk is designed to make the test...
