Abstract
The present invention is more particularly directed to a kind of method of the online capacity extension of RAID card.The method of the online capacity extension of the RAID card, the capacity extension of logic magnetic disc can be realized while hard disc data is retained, a variety of applications and the demand of the long-term use of client is disclosure satisfy that, substantially increases the service level of server, improve product competitiveness.
Description
Technical field
The present invention relates to hard-disk capacity expansion technique field, the method for more particularly to a kind of online capacity extension of RAID card.
Background technology
RAID（Redundant Array of Ind ependent Disks RAIDs, abbreviation disk battle array
Row）Card is that a kind of physical hard disk polylith independence differently combines to form a logic hard disk, so as to provide ratio
Single hard disk has higher performance and provides the technology of data redundancy.
The function of data redundancy is in user data once be damaged, can to obtain damage data using redundancy
To recover, so as to ensure the security of user data（In addition to RAID0）.Seem in user, the disk group of composition is like
One hard disk, user can carry out subregion to it, format etc..In a word, the operation to RAID card and the single mould one of hard disk one
Sample.Unlike, the storage performance of disk array is more much higher than single hard disk（Mainly in access speed）, and can carry
For data redundancy.
During the long-term use of client, there is a situation where that logic magnetic disc space is not enough, it is necessary to online sometimes
Capacity extension.The method of capacity extension has a lot, and simplest is exactly to increase hard disk quantity.But when hard disk full configuration, thinking
To realize that logic magnetic disc spatial spread turns into problem urgently to be resolved hurrily while hard disc data is retained.
The method for proposing a kind of online capacity extension of RAID card based on above-mentioned situation, the present invention, can preserve hard disk
While data, the purpose of logic magnetic disc spatial spread is realized, facilitates client to use.
The content of the invention
There is provided a kind of online capacity extension of simple efficient RAID card for defect of the invention in order to make up prior art
Method.
The present invention is achieved through the following technical solutions：
A kind of method of the online capacity extension of RAID card, it is characterised in that comprise the following steps：
（1）Start enters system, obtains root authority；
（2）RAID card management tool is copied under system under some file, the related letter that RAID card is configured to hard disk is obtained
Breath；
（3）Judge whether that whole hard drive spaces are all used for constituting RAID；
If whole hard drive spaces are all used for constituting RAID, using RAID rebuild characteristics, each one piece of homologous series of replacing
The hard disk and rebuild of more Large Copacity point, until all hard disks all change completion；Then, by remaining hard drive space extend into
In existing RAID, online capacity extension is realized；
If not whole hard drive spaces are all used for constituting RAID, then directly remaining hard drive space is extended into existing RAID
In, online capacity extension is realized, untapped hard drive space is directly added in logic magnetic disc；
（4）After Wait Order execution terminates, the result of capacity extension is checked, confirms data without loss.
When RAID card is PMC-RAID cards, the step（2）Middle RAID card management tool uses arcconf, passes through
Arcconf getconfig's 1 orders to obtain the relevant information of RAID card and hard disk configuration.
When RAID card is PMC-RAID cards, the step（3）In, will be remaining hard using arcconf modify orders
Disk space is extended into existing RAID, realizes online capacity extension.
The beneficial effects of the invention are as follows：The method of the online capacity extension of the RAID card, can retain the same of hard disc data
The capacity extension of Shi Shixian logic magnetic discs, disclosure satisfy that a variety of applications and the demand of the long-term use of client, substantially increases clothes
The service level of business device, improves product competitiveness.
Brief description of the drawings
Accompanying drawing 1 is the method schematic diagram of the online capacity extension of RAID card of the present invention.
Embodiment
In order that technical problems, technical solutions and advantages to be solved are more clearly understood, tie below
Drawings and examples are closed, the present invention will be described in detail.It should be noted that specific embodiment described herein is only used
To explain the present invention, it is not intended to limit the present invention.
The method of the online capacity extension of the RAID card, comprises the following steps：
（1）Start enters system, obtains root authority；
（2）RAID card management tool is copied under system under some file, the related letter that RAID card is configured to hard disk is obtained
Breath；
（3）Judge whether that whole hard drive spaces are all used for constituting RAID；
If whole hard drive spaces are all used for constituting RAID, using RAID rebuild characteristics, each one piece of homologous series of replacing
The hard disk and rebuild of more Large Copacity point, until all hard disks all change completion；Then, by remaining hard drive space extend into
In existing RAID, online capacity extension is realized；
If not whole hard drive spaces are all used for constituting RAID, then directly remaining hard drive space is extended into existing RAID
In, online capacity extension is realized, untapped hard drive space is directly added in logic magnetic disc；
（4）After Wait Order execution terminates, the result of capacity extension is checked, confirms data without loss.
When RAID card is PMC-RAID cards, the step（2）Middle RAID card management tool uses arcconf, passes through
Arcconf getconfig's 1 orders to obtain the relevant information of RAID card and hard disk configuration.
When RAID card is PMC-RAID cards, the step（3）In, will be remaining hard using arcconf modify orders
Disk space is extended into existing RAID, realizes online capacity extension.
The arcconf modify orders can realize the function of online capacity extension, can also realize that RAID is moved
The function of shifting, orders and is：
ARCCONF MODIFY <Controller#> FROM <LogicalDrive#> TO [Options] <Size> <
RAID#> <CHANNEL# ID#> [CHANNEL# ID#] ... [noprompt]
Wherein, Controller# numbers for controller, and LogicalDrive# is the logical drive number to be changed.
The RAID parameters to be changed, such as stripe size are included in [Options].Size represents size（MB）, RAID# is logical drive
The RAID of device：0,1,10,5,6,50,60 and simple_volume.Channel# ID# are the channel number and equipment of equipment
ID。
