Abstract
The invention provides a method for processing offline of a redundant array of inexpensive disk (RAID) hard disk. The method comprises the following steps of: guaranteeing to back up; checking cables; checking the fault of the hard disk; automatically or manually rebuilding the hard disk; checking by pressurization test; and exchanging components such as hard disk cables, a backboard and the like and confirming the pressurization test until no hard disk is offline so as to determine a reason of the offline of the hard disk and exchange and repair quickly. Compared with the prior art, the method for processing the offline of the RAID hard disk has the characteristics of rational checking steps, safety and reliability, comprehensive checking process, quick maintenance and the like; moreover, the reason of the offline of the hard disk can be determined quickly, the working efficiency of a field engineer is improved, and popularization and use are benefited.
Description
Technical field
The present invention relates to a kind of hard disk treatment technology that goes offline, the disposal route that specifically a kind of RAID hard disk goes offline.
Background technology
Early stage RAID card and the hard disk that uses all is scsi interface, and hard-disk capacity is more little, and RAID stability is just good more, the dish fault generally occurs falling, all is because hard disk itself has bad sector to cause.Along with the increase of hard-disk capacity and the increase of RAID degree of integration, it might not be that the fault of hard disk own causes that increasing raid falls to coil fault, all is the generation that cable or hard disk backboard etc. cause falling the dish fault a lot.
Such as in RAID5, when the hard disk of appearance more than two or two went offline, the state of array will become DEAD, and this array is with all to smash.Data are all lost.Therefore, how confirming the reason that hard disk goes offline fast and effectively, is the technical ability of field engineer's indispensability, in the RAID of prior art hard disk goes offline treating method, the most frequently used to mainly be following method:
1, the hard disk of script off-line can not be forced to reach the standard grade (outmoded or irrelevant);
If 2 find off working state, the hard disk lamp is no-trunk, should turn off power supply, power-on once more rapidly;
3, keep above-mentioned state, after the shutdown every hard disk is sticked the order label;
4, REBULD or initialization easily in the RAID control interface;
5, carrying out data recovers;
6, can not easily every dish be received the following operating system of XP (containing XP);
7, rapidly with the RAID off-line, cut off the electricity supply.
This method only is applicable to the emergency processing that the RAID hard disk goes offline, and still exists certain not enough in practical operation.
Summary of the invention
Technical assignment of the present invention is to solve the deficiencies in the prior art, and a kind of processing disposal route that comparatively comprehensive RAID hard disk goes offline is provided.
Technical scheme of the present invention realizes in the following manner, the disposal route that this a kind of RAID hard disk goes offline, and its processing procedure comprises:
Step 1: guarantee backup, specified data backs up before the processing hard disk goes offline fault;
Step 2: the cable inspection, check whether contact such as cable is intact, determine that hard disk goes offline whether to cause because of loose contact;
Step 3: hard disk failure inspection, check the RAID state, if single hard disk goes offline, RAID is a degrading state, detects all hard disks simultaneously, confirms whether hard disk has faults such as bad sector, be used for determining whether hard disk goes offline because hard disk failure causes, if hard disk has fault, then after changing this hard disk, this hard disk of automatic or manual REBULD;
Step 4: under the trouble-free prerequisite of hard disk, this hard disk of automatic or manual REBULD;
Step 5: the applied voltage test inspection, after above-mentioned steps is finished, under system, carried out applied voltage test 3-5 hour, check whether hard disk goes offline again;
Step 6: if no longer go offline, then former reason loose contact or the spread of voltage that early stage, hard disk went offline causes; If hard disk goes offline, then change parts such as hard disk cable, backboard, carry out applied voltage test again and confirm after pressurization, do not have hard disk to go offline;
Step 7: use rpms restart script RPMS repeating step five, step 6, until confirming do not have hard disk to go offline.
The testing time of restarting of above-mentioned steps seven is 50 times.
Described treatment step carries out when the RAID5 single hard disk goes offline.
The beneficial effect that the present invention is compared with prior art produced is:
The disposal route that a kind of RAID hard disk of the present invention goes offline can be checked out the reason that hard disk goes offline comprehensively, by seven steps, confirm the reason that hard disk goes offline fast, effectively reduce field engineer's workload, improve field engineer's work efficiency, be easy to promote the use of.
Embodiment
The disposal route that a kind of RAID hard disk of the present invention is gone offline is done following detailed description the in detail below.
The disposal route that this a kind of RAID hard disk goes offline, its processing procedure comprises:
Step 1: guarantee backup, specified data backs up before the processing hard disk goes offline fault;
Step 2: the cable inspection, check whether contact such as cable is intact, determine that hard disk goes offline whether to cause because of loose contact;
Step 3: hard disk failure inspection, check the RAID state, if single hard disk goes offline, RAID is a degrading state, detects all hard disks simultaneously, confirms whether hard disk has faults such as bad sector, be used for determining whether hard disk goes offline because hard disk failure causes, if hard disk has fault, then after changing this hard disk, this hard disk of automatic or manual REBULD;
Step 4: under the trouble-free prerequisite of hard disk, this hard disk of automatic or manual REBULD;
Step 5: the applied voltage test inspection, after above-mentioned steps is finished, under system, carried out applied voltage test 3-5 hour, check whether hard disk goes offline again;
Step 6: if no longer go offline, then former reason loose contact or the spread of voltage that early stage, hard disk went offline causes; If hard disk goes offline, then change parts such as hard disk cable, backboard, carry out applied voltage test again and confirm after pressurization, do not have hard disk to go offline;
Step 7: use rpms restart script RPMS repeating step five, step 6, until confirming do not have hard disk to go offline.
The testing time of restarting of above-mentioned steps seven is 50 times, can guarantee the accuracy of check result like this, finds the hard disk reason that goes offline fast and accurately.
Described treatment step carries out when the RAID5 single hard disk goes offline.
The disposal route that a kind of RAID hard disk of the present invention goes offline is compared with prior art, have characteristics such as the step of inspection is reasonable, safe and reliable, inspection is comprehensive, maintenance is quick, can confirm the reason that hard disk goes offline fast, improve field engineer's work efficiency, benefit and promote the use of.
