  • EN can obtain the chassis information (enclosure_index) where the hard disk is located and the controller information (canister_index) corresponding to each port preset port of each hard disk, that is, obtain the location information.

  • Two preset link Strands symmetrical between the upper and lower controls are recorded as a total link Chain.
  • Step S7 when EN finds that multiple disks on a strand have abnormal logins, it needs to accumulate the impact factors corresponding to each disk login. This requires setting three thresholds, namely, preset fault threshold T1, preset location threshold T2, and preset redundancy threshold T3.
  • the preset fault threshold T1 is the cumulative value of the impact factors of the login status (ie, login status) of all corresponding hard disks on the entire preset link Strand and the color number node port, which must be at least greater than 30 to meet the simultaneous EXCLUDSION of at least three disks.

  • the probability of multiple disks (at least 3 disks) losing frames at the same time is very small, so it can be considered that there is a problem with a certain section on the preset link Strand.

  • Step S11 After the first faulty controller is found, the controller needs to be isolated for fault.
  • step S7 if the value of bad_chain in step S7 is less than 1, the physical link of the controller's uplink port is found. At this time, the controller and the downstream controller on the same preset link Strand as the controller will no longer have the hard disk frame loss problem, thereby achieving the purpose of fault isolation. Then, an alarm of frame loss of the controller is reported.
  • the alarm information must include the enclosure_index of the chassis where the controller is located, the canister_index of the controller, the enclosure_index of the upstream chassis connected to the faulty controller, and the canister_index of the upstream controller. A line is limited by two points in the alarm information to determine the fault location.
  • step S7 if the value of bad_chain in step S7 is greater than 1, it means that the storage link has no redundancy at this time, and only the above alarm needs to be reported.
  • Step S12 when EN finds that only one disk on a preset link Strand has a login exception (a single disk does not distinguish login status), it considers that the disk with login exception is a problem of itself.
  • the storage system allows occasional disk login exceptions, but cannot tolerate disk login exceptions all the time. Therefore, when a single disk login exception is found for the first time, EN will perform anti-shake processing, start a 1h timer, and record the disk with login exception in the context of the EN module.

当今是一个数据爆炸的时代，每天都会有海量的数据产生，专业的存储设备为存储这些庞大的数据提可能性，在这些海量的数据中有些数据是非常重要的如金融数据，实验数据等等，这就要求存储设备不仅仅要有功能性还需要有可靠性。
但是，存储设备在长时间的持续运行过程中，硬件难免会出现损耗，硬件的损耗就会引起硬件的异常，间接的带来软件上的异常。硬件链路故障是一种常见的硬件故障，可以表现为在一条很长的硬件的链路上的某一段或某几段发生故障。而现有技术无法在一段很长的链路上准确识别出故障位置或范围，因此智能对该链路进行全部整修，会增加检修范围，降低检修效率。
针对上述现有技术无法在链路中进行故障位置的准确定位的问题，目前尚未提出有效的解决方案。

在本申请实施例中，获取存在故障的目标链路中至少一个目标端口的登录状态，其中，目标链路用于按照预设链路顺序连接至少一个硬盘的目标端口；在预设集合中查询每个登录状态对应的影响因子，其中，预设集合用于记录多种登录状态，和每种登录状态对应的影响因子；按照预设链路顺序逐个累加每个目标端口对应的影响因子，并将每次累加结果与预设定位阈值进行比较；在累加结果大于预设定位阈值的情况下，确定最后累加的影响因子对应的目标端口为故障端口，可以在存在故障的目标链路中确定产生故障的故障端口，实现了对故障的目标链路进行故障位置的准确定位的技术效果，进而解决了现有技术无法 在链路中进行故障位置的准确定位技术问题。
可选地，上述故障定位方法可以用在具有多个硬盘的存储系统中，该存储系统中多个硬盘可以采用磁盘阵列的方式存储数据。
可选地，每个硬盘可以包括两个预设端口，分别记为第一预设端口和第二预设端口。

在上述步骤S104中，影响因子用于通过数值的方式表示目标端口或预设端口的丢帧程度。
可选地，不同登录状态存在不同的影响因子，例如，GOOD＝0，IN DOUBT＝1，DEGRADED＝4，EXCLUDSION＝10。
在上述步骤S106中，预设定位阈值用于对目标链路中存在故障的位置进行定位，在存在故障的目标链路中，逐个累加该目标链路中每个目标端口对应的影响因子，并将每次累加结果与预设定位阈值进行比对，若累加了某一目标端口对应的影响因子后大于预设定位阈值，则说明之后累加的目标端口处存在故障，实现了对故障端口的定位，便于后续对故障端口进行检修或隔离。
可选地，可以预先记录每个硬盘和预设端口的位置信息，该位置信息信息至少包括：预设机箱信息和预设控制器信息，预设机箱信息用于表示每个硬盘所在机箱的唯一标识，预设控制器信息用于表示每个机箱中与硬盘的预设端口连接控制器的唯一标识，在确定故障端口后可以查询该故障端口的预设控制器信息，实现对故障端口的定位。
需要说明的是，每个硬盘的预设端口通过控制器与预设链路连接，由于控制器和预设端口一一对应，因此，可以通过确定故障端口的控制器，实现对故障端口的定位。
作为一种可选的实施例，在获取存在故障的目标链路中至少一个目标端口的登录状态之前，方法还包括：获取预设链路中至少一个预设端口的登录状态，其中，预设链路用于连接至少一个硬盘的预设端口；在预设集合中查询每个登录状态对应的影响因子，其中，预设集合用于记录多种登录状态，和每种登录状态对应的影响因子；累加预设链路中全部预设端口的影响因子，确定预设链路的评价结果；在评价结果大于预设故障阈值的情况下，确定预设链路为存在故障的目标链路。
本申请上述实施例，在从故障的目标链路中进行故障定位之前，还需要逐个确定每条预设链路是否属于存在故障的目标链路，进而在确定目标链路的过程中，可以累加每条预设链路中各预设端口对应的影响因子，得到该条预设链路的评价结果，然后将该条预设链路的评价结果与预设故障阈值进行比较，在该条预设链路的评价结果大于预设故障阈值的情况下，说明该条预设链路存在故障，则确定该预设链路为目标链路，实现了对存在故障的目标链路的初步定位。
作为一种可选的实施例，在获取预设链路中至少一个预设端口的登录状态之前，方法还包括：向待检测硬盘集合发送广播信息，其中，待检测硬盘集合包括至少一个硬盘，每个硬盘包括两个预设端口；接收待检测硬盘集合返回的位置信息，其中，位置信息至少包括：预设机箱信息和预设控制器信息，预设机箱信息用于表示每个硬盘所在机箱的唯一标识，预设控制器信息用于表示每个机箱中与硬盘的预设端口连接控制器的唯一标识；根据预设机箱信息和预设控制器信息，确定预设链路，其中，预设链路用于级联多个机箱中具有同一标识的控制器。

作为一种可选的实施例，获取预设链路中至少一个预设端口的登录状态包括：检测每个预设端口的丢帧信息，其中，丢帧信息至少包括丢帧数量；在预设区间集合中确定丢帧数量对应的预设丢帧区间为目标丢帧区间，其中，预设区间集合包括多个预设丢帧区间，每个预设丢帧区间预先设有对应的预设丢帧状态；确定目标丢帧区域对应的目标丢帧状态为登录状态。
本申请上述实施例，登录状态表示对应目标端口或预设端口的丢帧情况，因此，登录状态可以根据丢帧数量确定，通过预先划分多个预设丢帧区间，并为每个预设丢帧区间设置相应的预设丢帧状态，进而确定与预设端口或目标端口的丢帧数量对应的预设丢帧区间为目标丢帧区间，并将该目标丢帧区间的预设丢帧状态作为该预设端口或目标端口的登录状态，实现了对登录状态的确定。
作为一种可选的实施例，在获取预设链路中至少一个预设端口的登录状态之后，方法还包括：在登录状态表示预设端口存在异常的情况下，按照预设时间间隔获取预设端口在目标时刻的登录状态；在预设端口在目标时刻的登录状态仍然表示预设端口存在异常的情况下，对预设端口所在硬盘进行隔离。
本申请上述实施例，若硬盘偶尔出现了少量的丢帧可以被存储系统容忍，但是若硬盘频繁出现丢帧就需要对该硬盘进行处理，所以检测到预设端口的登录状态出现异常的情况下，可以按照预设时间间隔，在目标时刻再次获取预设端口的登录状态，若预设端口在目标时刻的登录状态仍然表示预设端口存在异常的情况下，说明该预设端口出现频繁丢帧的情况，则需要将该预设端口所在硬盘从存储系统中分离出来，实现对故障硬盘的隔离。

本申请上述实施例，存储系统中每个总链路可以设置两条预设链路，且两条预设链路互为冗余备份，若其中一条预设链路出现异常，那么还可以使用另一条预设链路继续进行数据传输，因此，需要适时了解总链路的冗余情况，进而可以将总链路中每条链路中全部预设端口对应影响因子的评价结果与预设冗余阈值进行比较，若评价结果大于预设冗余阈值，则说明该预设链路存在异常，需要调用总链路中冗余的另一条预设链路满足数据传输需求，并为总链路添加第一冗余标记；进而若总链路中的两条预设链路都出现了异常，则说明总链路已经无法满足数据传输需求，故需要停机报警，等待检修。
作为一种可选的实施例，在确定最后累加的目标端口为故障端口之后，方法还包括：获取故障端口的目标控制器信息，其中，目标控制器信息为故障端口连接控制器的唯一标识；获取故障端口所在硬盘的目标机箱信息，其中，目标机箱信息为故障端口所在硬盘的机箱的唯一标识；根据目标控制器信息和目标机箱信息，生成告警信息。

本申请上述实施例，若硬盘偶尔出现了少量的丢帧可以被存储系统容忍，但是若硬盘频繁出现丢帧就需要对该硬盘进行处理，所以检测到目标端口的登录状态出现异常的情况下，可以按照预设时间间隔，在目标时刻再次获取目标端口的登录状态，若目标端口在目标时刻的登录状态仍然表示目标端口存在异常的情况下，说明该目标端口出现频繁丢帧的情况，则需要将该目标端口所在硬盘从存储系统中分离出来，实现对故障硬盘的隔离。
作为一种可选的实施例，对目标端口所在硬盘进行隔离包括：确定目标端口所在硬盘为目标硬盘；将目标硬盘的设置为关闭状态，其中，在目标硬盘处于关闭状态的情况下，断开目标硬盘的全部端口。

本申请上述实施例，存储系统中每个总链路可以设置两条预设链路，且两条预设链路互为冗余备份， 若其中一条预设链路出现异常，那么还可以使用另一条预设链路继续进行数据传输，进而在对故障端口进行故障隔离的过程中，可以先根据总链路的冗余标记，确定该总链路是否具有满足故障隔离的冗余条件，然后在总链路存在指示总链路不存在异常链路的第二冗余标记，可以实现对故障端口的故障隔离。
本申请还提供了一种可选实施例，该可选实施例提供了一种基于硬盘命令丢帧的存储硬件链路状态监控方法。可以基于分析发生丢帧的硬盘数量和单块丢帧的严重程度，识别出故障链路的位置，根据不同的链路故障采取对应的故障隔离措施，有效的保障了系统的稳定性，当故障发生时可以准确的识别出故障原因并进行相应的处理，能够在一段很长的链路上准确的识别出故障位置或范围。
图2是根据本申请实施例的一种基于硬盘命令丢帧的存储硬件链路状态监控方法架构的示意图，如图2所示，包括：机箱管理层(EN)，协议层，驱动层，物理链路层。
可选地，物理链路层在最低层，为存储系统和硬盘之间命令或数据传输的物理通道。
可选地，协议层和驱动层是存储系统和硬盘之间通信的数据通道。
可选地，机箱管理层位于最上层作用是根据协议层返回的每块硬盘的丢帧程度(也即登录状态)判断故障位置，触发故障隔离动作。
可选地，每块硬盘有两个预设端口port，每个预设端口port的丢帧程度(也即登录状态)分为四个等级：
GOOD：无丢帧异常，对EN的影响因子0。
IN DOUBT:存在丢帧：至少存在一次丢帧，但是还未到达DEGRADED的程度，对EN的影响因子1。
DEGRADED:盘存在丢帧：一定数量的丢帧，大于IN DOUBT但是未达到EXCLUSION的程度，对EN的影响因子4。
EXCLUDSION：盘存在大量的丢帧，对EN的影响因子10。
可选地，机箱管理层中记录着每块硬盘都有两条属性(也即位置信息)，硬盘所在机箱和硬盘所在控制器。当单块盘出现丢帧时，认为是盘的单体故障，但是需要做防抖处理，避免误操作；当多快盘丢帧时，因为多块盘同时丢帧的概率很小，因此故障可能不在盘上，这时需要设置多个阈值，将多块盘的影响因子进行叠加，判断是否达到阈值和这些盘所在的机箱和控制器，进一步判断出故障发生在硬件链路的哪个位置，进而机箱管理层针对检测出的故障位置，进行对应的故障隔离操作，并及时上报告警。
本申请上述实施例，存储设备能够及时的发现机框是否存在链路故障的情况，进而对异常链路进行相应的排障处理，保证了存储系统的安全性和可靠性，使产品质量和生产业务得到了保障。
作为一种可选的实施例，基于硬盘命令丢帧的存储硬件链路状态监控方法的实施过程包括步骤如下：
步骤S1，存储系统正常启动运行。
步骤S2，SAS Expander芯片是一种可编程芯片，可以发布广播事件，机箱管理层(EN)收到广播后，发起Discovery(也即发现机制)，Discovery完成后EN可以拿到硬盘所在机箱信息(enclosure_index)和每块硬盘的每个port预设端口对应的控制器信息(canister_index)，也即获取位置信息。
步骤S3，EN通过订阅协议层里每块硬盘的每个port预设端口的丢帧信息，每次Discover完成后检查丢帧信息。
步骤S4，协议层通过SCSI协议规则和驱动返回命令执行状态，对每个盘的每个port预设端口的丢帧状态进行设置，丢帧状态记作盘的login状态(也即登录状态)。
可选地，login状态(也即登录状态)包括：GOOD：无丢帧异常；IN DOUBT:存在丢帧：至少存在一次丢帧，但是还未到达DEGRADED的程度；DEGRADED:盘存在丢帧：一定数量的丢帧，大于IN DOUBT但是未达到EXCLUSION的程度；和EXCLUDSION：盘存在大量的丢帧。
步骤S5，协议层对盘描述的不同login状态(也即登录状态)对EN有不同的影响因子，GOOD＝0，IN DOUBT＝1，DEGRADED＝4，EXCLUDSION＝10。
步骤S6，确定预设链路Strand和总链路Chain，其中，每条总链路Chain包括两条预设链路Strand。
图3是根据本申请实施例的一种存储硬件链路的示意图，如图3所示，enclosure0是主柜，enclosure1-3挂的是硬盘框(也即机箱)对应enclosure_index＝1-3，每个机箱分上下两部分对应canister_index＝0和1，其中，硬盘分布在enclosure1-3中，每个机箱直线通过SAS线缆级联起来，从主柜同一各SASport出来的，一直到级联最底部的这条硬件链路记为预设链路Strand，盘的每个与预设端口port对应一条预设链路Strand。上下控对称的两条预设链路Strand记为一条总链路Chain。
步骤S7，当EN发现一条strand上有多块盘login异常，此时需要根据每块盘login对应的影响因子进行累加。这是需要设置三个阈值，预设故障阈值T1，预设定位阈值T2和预设冗余阈值T3。
可选地，预设故障阈值T1为整个预设链路Strand上所有与之对应硬盘的与色号节点port的login状态(即登录状态)的影响因子的累加值，至少要大于30，满足至少三块盘同时EXCLUDSION。
可选地，预设定位阈值T2为当前预设链路Strand上某个控制器所对应硬盘的预设端口port的login状态(即登录状态)的影响因子的累加值T2要小于T1，可以按6分来算，用于寻找单条预设链路Strand上首个故障点的位置。
可选地，预设冗余阈值T3为总链路Chain阈值，T3要小于T1，因为总链路Chain表示一对预设链路 Strand，当两条预设链路Strand上都有login状态(即登录状态)异常时，说明没有冗余链路，此时存储系统极其不安全。因此T3比T1低，优先上报总链路Chain异常告警，当一个总链路Chain上的两条预设链路Strand每出现一条预设链路Strand的盘login状态(即登录状态)的影响因子累加值大于T3时，将变量(也即冗余标记)bad_chain+1(bad_chain初始值为0)。
步骤S8，每条预设链路Strand上的login(即登录状态)的影响因子累加值统计完成之后，开始进行链路故障异常点判断。
步骤S9，当预设链路Strand上盘的login状态(即登录状态)大于T1时代表有多块盘出现了login(即登录状态)异常，多块盘(至少3块)同时出现丢帧的概率是很小的，因此可以认为是预设链路Strand上的某一段出了问题。
步骤S10，再遍历步骤S9中发现故障的预设链路Strand上所有控制器所对应盘的login状态(即登录状态)的影响因子累加值与T2比较。找到首个对应的盘的累加因子大于T2的控制器，这个控制器就是首先发生故障的控制器(对应故障端口)。
步骤S11，找到首个故障控制器后需要对控制器进行故障隔离。
可选地，故障隔离时，如果步骤S7中bad_chain的值小于1，则找到该控制器的上行口物理链路，此时该控制器和与该控制器在同一条预设链路Strand上的下游控制器将不会再发生硬盘丢帧问题，达到故障隔离的目的，然后上报该控制器出现丢帧的告警，告警信息中要包含本控制器所在机箱的enclosure_index、控制器的canister_index，与该故障控制器相连的上游机箱的enclosure_index和上游控制器的canister_index，告警信息中通过两个点限制了一条线，确定了故障位置。
可选地，如果步骤S7中bad_chain的值大于1，表示此时存储链路无冗余，此时仅需要上报上述告警。
步骤S12，当EN发现在一条预设链路Strand上只有一块盘出现login异常(单盘不区分login状态)，则认为login异常盘是自身的问题，存储系统是允许盘偶尔login异常，但不能容忍盘一直login异常，因此，在首次发现单盘login异常时，EN要进行防抖处理，启动1h定时器，同时记录此login异常的盘到EN模块的上下文中。
可选地，在定时器的时间到后(也即达到目标时刻)，获取盘最新的login状态(即登录状态)，如果此时有盘login异常且与1h前login异常的盘是同一块盘，则对这块盘上报告警，RAID模块检测到这块盘有告警后可以将这块盘置为Fail状态，让这块盘退出RAID，EN检测到盘Fail则需要将这块盘的物理预设端口port关闭，达到故障隔离的作用。用户根据告警信息找到对应的故障盘，进行换盘操作。
步骤S13，通过上述步骤存储系统能够在链路故障发生时，自动识别是点故障(盘)，还是线故障(盘，控制器)，并进行对应硬件上的故障隔离，防止引发更多的软件异常，保障存储的稳定性。
步骤S14，上述提到的所有告警通过GUI界面对用户进行展示。
