为使本申请实施例的目的、技术方案和优点更加清楚,下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
实施例一
请参考图1,图1为本申请实施例所提供的一种存储系统的控制器升级方法的流程示意图,参考图1所示,该方法主要包括:
S101:从背板上的第一存储器中读取第一ID(Identity Document,身份标识)值;
S102:从主板上的第二存储器中读取第二ID值;其中,在存储系统中的双控制器升级更换前,第一ID值与第二ID值相等,且当其中的一个控制器升级更换后,第二ID值变为升级更换后的控制器对应的板卡ID值;
具体的,本申请所提供的技术方案中,存储系统设置有双控制器,双控制器实现数据备份,且双控制器彼此监控对方的运行状态。另外,本申请在背板以及主板上均设置一个存储器,并在背板与主板上的存储器中均设置一个寄存器,分别在背板上的存储器即第一存储器的寄存器中写入第一ID值,在主板上的存储器即第二存储器的寄存器中写入第二ID值。在控制器升级更换前,背板上的第一存储器中的第一ID值与主板上的第二存储器的第二ID值相等。在控制器升级过程中,背板上的第一存储器中的第一ID值保持不变,当将存储器系统的双控制器中的一个控制器升级更换后,第二ID值变为升级更换后的控制器对应的板卡ID值。由此,系统通过比较第一ID值与第二ID值的大小即可确认是否已升级更换了一个控制器。其中,上述第一存储器与第二存储器均可为带电可擦可编程只读存储器,即EEPROM。
S103:判断第一ID值与第二ID值是否不等;
S104:若第一ID值与第二ID值不等,则将数据迁移到升级更换后的控制器中,以在数据迁移完成后,升级更换另一个控制器。
具体的,系统在读取第一ID值与第二ID值的基础上,进一步比较二者的大小,判断第一ID值与第二ID值是否不等,即识别是否已升级更换了一个控制器。若第一ID值与第二ID值不等,则系统自动将还未升级更新的控制器中的数据迁移到已升级更换的控制器中,并自动进行相应的软件配置。操作人员确认数据已迁移完成后,即可对还未升级更换的控制器进行升级更换。相返,若第一ID值与第二ID值相等,则表示控制器未升级更新,系统正常启动。
其中,在一种具体的实施方式中,上述判断第一ID值与第二ID值是否不等,包括:判断第二ID值是否大于第一ID值。
具体的,本实施例中,控制器的版本越高,其对应的板卡ID值越大,当将存储系统中的一个控制器升级更换为更高版本的控制器后,第二ID值相应的变为此更高版本的控制器对应的板卡ID值,即第二ID值相应的增大,进而在读取第一DI值与第二ID值的基础上,系统进一步判断第二ID值是否大于第一ID值。若第二ID值大于第一ID值,则系统自动将还未升级更新的控制器中的数据迁移到已升级更换的控制器中,并自动进行相应的软件配置。
例如,控制器未升级前,控制器对应的板卡ID值为1,则第一存储器中的第一ID值等于1,第二存储器中的第二ID值等于1,当将存储系统的双控制器中的一个升级更换后,升级更换的控制器对应的板卡ID值为2,此时将第二ID值修改为2。当系统读取第一ID值与第二ID值,判断出第二ID值大于第一ID值后,将数据迁移至升级更换后的控制器中。
综上所述,本申请所提供的存储系统的控制器升级方法,存储系统设置双控制器,先后分别对各控制器进行升级更换,当升级更换其中一个控制器时,另一个控制器正常工作,从而实现在不停机的情况下,升级控制器。另外,在背板与主板上分别设置第一存储器与第二存储器,在升级更换控制器前,第一存储器存储的第一ID值与第二存储器存储的第二ID值相等,当升级更换了其中的一个控制器后,第二ID值变为升级更换后的控制器对应的板卡ID值,由此,当系统判断出第一ID值与第二ID值不等 时,自动将数据迁移到已升级更换的控制器中,实现数据的自动迁移,操作人员仅需在数据迁移完成后将另一控制器升级更换即可,而无需操作人员进行数据迁移动作,从而极大的节省了操作人员的配置时间,降低了操作人员的工作量,提高了升级效率。
实施例二
请参考图2,图2为本申请实施例所提供的另一种存储系统的控制器升级方法的流程示意图,参考图2所示,该方法主要包括:
S201:从背板上的第一存储器中读取第一ID值;
S202:从主板上的第二存储器中读取第二ID值;其中,在存储系统中的双控制器升级更换前,第一ID值与第二ID值相等,且当其中的一个控制器升级更换后,第二ID值变为升级更换后的控制器对应的板卡ID值;
S203:读取目标器件的目标GPIO(General-purpose input/output,通用输入输出)管脚的值,并根据目标GPIO管脚的值得到第三ID值;其中,第三ID值等于升级更换后的控制器对应的板卡ID值;
S204:判断第二ID值与第三ID值是否相等;
S205:若第二ID值与第三ID值相等,则判断第一ID值与第二ID值是否不等;
S206:若第一ID值与第二ID值不等,则将数据迁移到升级更换后的控制器中,以在数据迁移完成后,升级更换另一个控制器;
S207:若第二ID值与第三ID值不相等,则进行故障报错。
具体的,本实施例在背板与主板上分别设置存储器并设置第一ID值与第二ID值的同时,还利用硬件设置第三ID值,此第三ID值由目标器件的目标GPIO管脚的值决定。具体而言,在控制器升级更换前,背板上的第一存储器中的第一ID值与主板上的第二存储器的第二ID值以及第三ID值相等。在控制器升级过程中,背板上的第一存储器中的第一ID值保持不变,当将存储器系统的双控制器中的一个控制器升级更换后,第二ID值与第三ID值均变为升级更换后的控制器对应的板卡ID值。第二ID值由操作人员写入第二存储器,第三ID值由操作人员设置目标器件的目标GPIO管脚的值得到。其中,操作人员设置目标器件的目标GPIO管脚的值的方式为将目标GPIO 管脚连接上拉电阻或下拉电阻而设置目标GPIO管脚的值。另外,目标器件可以为CPLD(Complex Programmable Logic Device,复杂可编程逻辑器件)。
参考图3所示,以目标GPIO管脚为GPIO1与GPIO2为例,当存储系统的双控制器中的一个控制器升级更换后的控制器对应的板卡ID值为2时,此时可将GPIO1管脚连接上拉电阻,由于上拉电阻连接电源,故此时GPIO1管脚为高电平,其值为1;可将GPIO管脚连接下拉电阻,由于下拉电阻接地,故此时GPIO2管脚为低电平,其值为0。在二进制下,10即表示十进制的板卡ID值2。
系统读取第一ID值、第二ID值以及确定第三ID值后,首先比较第二ID值与第三ID值的大小,若第二ID值与第三ID值不相等,则进行故障报错,提示系统异常。若第二ID值与第三ID值相等,则进一步比较第一ID值与第二ID值的大小,若第二ID值与第一ID值不等,则进行数据迁移。在随着控制器的升级,第二ID值与第三ID值均增大的情况下,即若第二ID值等于第三ID值且大于第一ID值,则进行数据迁移,若第二ID值等于第三ID值等于第一ID值,则表示控制器未升级。若第二ID值不等于第三ID值,如第二ID值等于第一ID值不等于第三ID值,或第一ID值等于第三ID值不等于第二ID值时,此时进行故障提示。
本实施例采用设置三个ID值的方式进行升级判断,识别系统异常,在能够在不停机的情况下升级控制器以及系统自动进行数据迁移的同时,还可增加升级可靠性。
进一步,在上述各实施例的基础上,还包括:存储系统中的双控制器升级更换后,将第一ID值更新为升级更换后的控制器对应的板卡ID值。
具体而言,当前完成控制器升级后,第二ID值与第三ID值均相应的变为升级更换后的控制器对应的板卡ID值。若第一ID值保持不变,则控制器升级后始终存在第二ID值与第三ID相等且与第一ID值不等的情况,由此会重复不断触发自动进行数据迁移的动作。为此,本实施例在存储系统中的双控制器升级更换后,将第一ID值更新为升级更换后的控制器对应的板卡ID值,此后,第一ID值、第二ID值以及第三ID值均相等,不会触发数据迁移,从而有效规避了数据迁移不断重复进行,保障了系统的可靠性。
