Description
Technical field
The present invention relates to server test field, specifically a kind of quick reproduction SAS card task abort problems
Method and device.
Background technology
With the rise of big data and the Internet, applications, the application range of server is more and more wider.Client is for high speed
The demand of data storage is increasing, and RAID card plays the role of that its is irreplaceable in secure data area, but relative to SAS
For card, to property loss of energy also bigger, so SAS cards are in practical applications because the high speed of its IO has irreplaceable work
With.
Task abort problems are typically all system or SAS controller for IO responses not in time, caused by order
Disconnected, it is formed with very big relation with processor of the SAS controller for FIFO (first in first out).
Existing traditional test methods, are all states when simulating normal use, but in actual application environment, it is non-
It is very low to read and write the frequency that IO is produced, causes the generation probability of task abort problems also than relatively low, for task abort problems
Test it is ineffective.
The content of the invention
To solve the above-mentioned problems, there is provided a kind of method and device of quick reproduction SAS card task abort problems, leads to
Cross that fast parallel operation read-write IO (fastpath) and non-read-write IO (nonfastpath) are quick to be reappeared task abort and ask
Topic, improves test effect.
An embodiment of the present invention provides a kind of method of quick reproduction SAS card task abort problems, the method bag
Include：
S1：Build a linux system environment；
S2：IO read-writes are carried out to hard disk；
S3：Non- read-write IO is produced to hard disk；
S4：Read-write IO and non-read-write IO is kept to be carried out at the same time, until producing task abort mistakes in system log.
Further, the specific implementation process of step S2 is：
S21：Configure FIO environment；
S22：Fio scripts are run, IO read-writes are carried out to hard disk by fio orders.
Further, the specific implementation process of step S3 is：Sync_cache is run, is sent out by sg_raw orders to hard disk
High-level command is sent, produces non-read-write IO.
Further, in step s3, the time of synchronous cache is adjusted by changing the sleep times.
The embodiment of the present invention additionally provides a kind of device of quick reproduction SAS card task abort problems, the device
It is arranged under linux system, the device includes：
IO generation modules are read and write, IO read-writes are carried out to hard disk for sending order；
Non- read-write IO generation modules, for sending high-level command or complex command to hard disk, produce non-read-write IO.
Further, the read-write IO generation modules are fio scripts, for generating fio orders.
Further, the non-read-write IO generation modules are sync_cache scripts, for generating sg_raw orders.
Further, the device further includes：
Clock synchronization module, for adjusting the time of non-read-write IO so that hard disk receive read-write IO and non-read-write IO when
Between put it is synchronous.
The effect provided in the content of the invention is only the effect of embodiment, rather than whole effects that invention is all, above-mentioned
A technical solution in technical solution has the following advantages that or beneficial effect：
1st, read and write by the actual IO of fio orders simulation, hard disk smart etc. is obtained in sg_raw orders simulation practical business
Non- read-write IO caused by information, is performed by the synchronization of fio and sg_raw, quickly reappears task abort problems, can be with
Fast verification for issue-resolution imports, and can be also used for quickly screening the SAS cards not gone wrong,
The failure for carrying out early stage is evaded.
2nd, the time of synchronous cache is adjusted by changing the sleep times, farthest improves sg_raw and produce non-reading
The frequency of IO is write, farthest to improve the probability of reproduction problem, improves test quality.
