Embodiment
More detailed elaboration is carried out to present disclosure below：
Disk state information acquisition method：During hot-swappable, disk state is divided into hard disk and extracts state and hard disk insertion
State.It is able to record that information is extracted or inserted to hard disk under server Linux system/var/log/messages files.Work as hard disk
After extraction, a band can be produced in/var/log/messages files keyword " Synchronizing SCSI cache "
Daily record；Can produce a band after hard disk inserts and is identified, in/var/log/messages files has keyword
" Attached SCSI disk " daily record.The judgement of disk state information is exactly to utilize this feature, is carried by calculating
" Synchronizing SCSI cache " daily record and with " the quantity sum of Attached SCSI disk " daily record, come
It is in extraction or insert state to judge hard disk.
Keyword " Synchronizing SCSI cache " daily record is carried in setting/var/log/messages files
Bar number is hotplug_A, and with keyword, " Attached SCSI disk " daily record bar number is hotplug_B.hotplug_A
It is hotplug_C with hotplug_B sums.Test before first empty/var/log/messages files in content.Now,
Hotplug_A is 0, hotplug_B 0, and hotplug_C is also 0；After a hard disk is extracted, hotplug_A 1,
Hotplug_B is 0, therefore hotplug_C is also 1；After inserting hard disk and recognizing, hotplug_A 1, hotplug_B 1,
Therefore hotplug_C is also 2；After a hard disk is extracted again, hotplug_A 2, hotplug_B 1, therefore hotplug_C
For 2；After inserting hard disk and recognizing, hotplug_A 2, hotplug_B 2, therefore hotplug_C is also 4.Therefore, often pull out
Go out or insert hard disk once, hotplug_A will increase by 1 with hotplug_B sums hotplug_C.Can be brighter by following table
