HBA解决办法

第一步：取两个以太网线，分别连接到控制器A 和控制器B 的以太口上，这里我分别连接到了192.168.128.101 和192.168.128.102。

注意：这里必须连接到同一网段的以太口。

第二步：将这两个网线连接到hub或者交换机上，接着再取一根网线和你的笔记本相连。

要求你的IP地址是192.168.128这个网段。

第三步：打开你的storage manage 软件，如下图：
第四步：右键点击左边的图标，选择automatic discovery，查找当前的的子系统服务。

第五步：在子系统中，你会看见工具栏上有一根图标在闪烁，点击它出现一个错误日志，根据这个日志进行解决你的问题。

这里只说明一下控制器自动切换的带来错误的问题。

最后一步：解决问题（Array >> Change >> Ownership/Preferred Path or Logical Drive >> Change >> Ownership/Preferred Path）进行解决吧。

如何更换连接IBM存储DS4000的主机HBA卡

热插拔更换连接DS4000的HBA卡1. 检查是否满足AIX版本和文件集的最低要求注意：●在热插拔更换HBA卡的过程中，dar的autorecovery属性必须设置为否（no），否则有丢失数据访问的可能。

●必须在确认HBA卡更换完成，后续的配置工作也完成之后，才可以“Redistribute LogicalDrives to the Preferred Path”，否则有丢失数据访问的可能。

2. 准备工作（1）查看HBA卡当前状态# lsdev -C | grep fcs# lsdev -C | grep dac# lscfg -vpl fcsX记录故障HBA卡的WWPN号# lsdev -C | grep dar（2）查看DAR的autorecovery属性# lsattr -El darX确认autorecovery的属性为no。

如果autorecovery的属性为Yes，需用如下命令手动关闭。

# chdev -l darX -a autorecovery=no3. 热插拔更换（1）删除需更换的fcs卡，将其状态置为defined# redev -Rl fcsX输入如下：（2）物理更换HBA卡diag -> Task Selection -> Hot Plug注意：此时不要将光纤线插回新换上的HBA卡（3）用光纤环回堵头测试新更换上的HBA卡将fibre channel loop back堵头插入HBA卡# cfgmgr注意：新的HBA卡会被放在Mapping里的Default Group中，如果Default Group中存在hdisk 的映射，则在cfgmgr之后对应新的HBA卡会产生多余dar和dac设备。

在后面更新完Mapping 中的WWPN信息后，使用rmdev命令删除多余的dar和dac设备。

检查更换上的HBA卡为Available状态# lsdev -C | grep fcsX检查更换上的HBA卡是否需要升级微码# lscfg -vpl fcsX记录“network address”，即新HBA卡的WWPN号码。

英语写作闪光句型

英语写作闪光句型英语写作的考查目的是什么?理应了解考查中国学生的英语作文，其目的并不完全是看考生把题目论述得如何好，是否把提示的内容都表达出来(当然这也是一个方面)，更重要的是考查学生的英语语言能力，即英语表达能力。

因此，在英语写作考试中，不仅仅是把内容写出来就可以了，而应更多地考虑怎么把自己的语言水平表现出来。

许多考生没有意识到这一点，往往是想到什么词就写什么词，没有停下来稍微思考一下：还有没有更好、更贴切的词，还有没有更生动、更有力的句子结构。

应当看到，我们的阅卷人员几乎都是中国教师，而非外国人，他们更重视语言，也就是说，是精彩的遣词造句使文章赢得阅卷人的好感而得到高分，而不是由于论述得如何出色而帮助得分。

在内容基本雷同、语言普遍平淡的作文中，出现一篇用词、用句都不同寻常的文章，会使阅卷人眼前一亮，高分作文往往就是这样产生的。

因此，掌握最具有得分点的闪光句型和经典词语，迅速摆脱语言的障碍，是在短时间内迅速提高英语语言表达能力的捷径。

一、开头段的闪光句型开头段一定要语言精炼，并且直接切入主题。

开头段一般不对主题进行深入的探讨，具体的论证或叙述应该在扩展段进行。

开头段的作用为：概括陈述主题，提出观点或论点，表明写作意图。

1.The arguer may be right about…, but he seems to neglect (fail) to mention (take into account) the fact that…2.As opposed to (Contrary to) widely (commonly/generally) held (accepted) belief (ideas/views), I believe (argue) that…3.Al though many people believe that…, I doubt (wonder)whether the argument bears much analysis (close examination).4.The advantages of B outweigh any benefit we gained from (carry more weight than those of/are much greater than) A.5.Although it is commonly (widely/generally) held(felt/accepted/agreed) that…, it is unlikely to be true that…6.There is an element of truth in this argument (statement), but it ignores a deeper and more basic (important/essential) fact (reason) that…7.It is true that (Tr ue,/To be sure,/Admittedly,)…, but this is not to say (it is unlikely/it doesn’t follow/it doesn’t mean/it won’t be the case) that…8.The main (obvious/great) problem (flaw/drawback) with (in) this argument (view/remark) is that it is ignorant of (blind to) the basic (bare) fact that…9.It would be possible (natural/reasonable) to think (believe/take the view) that…, but it would be absurd (wrong) to claim (argue) that…10.In all the discussion and debate over…, one important (basic) fact is generally overlooked (neglected).11.There is absolutely (in fact) no (every) reason for us to believe (accept/resist/reject) that…12.Logical (Valid/Sound) as this argument and I wholeheartedly agree with it, it appears insignificant (absurd) when…is taken int o consideration(account).13.To assume (suggest) that…is far from being proved (to miss the point).14.A close (careful) inspection (examination/scrutiny) of this argument would reveal how flimsy (groundless/fallacious) it is.15.On the surface (At first thought), it (this) may seem a sound (an attractive) suggestion (solution/idea), but careful weighing on the mind (on closer analysis/on second thought), we find that…16.Too much emphasis placed on (attention paid to/importance attached to)…may obscure (overlook/neglect) other facts…17.The danger (problem/fact/truth/point) is that…18.What the arguer fails to understand (consider/mention) is that…19.However just (logical/sound/valid) this argument may be, it only skims the surface of the problem.20.Among the most convincing (important) reasons given(cited/offered/identified) by people for…, one should be stressed (emphasized/mentioned).21.I believe that the title statement is valid because (of)…22.I agree with the above statement be cause I believe that…23.Although I appreciate that…, I cannot agree with the title statement.24.There is a public controversy nowadays over the issue of… Those who object to…argue that… But people who favor…, on the other hand, argue that…二、中间段的闪光句型中间段是文章的正文，其作用是从不同的层面对文章主题进行具体和详实的解释和论证。

Logical Drive Not On Preferred PathWhat Caused the Problem?There is a problem accessing the controller listed in the Recovery Guru Details Area. Any logical drives that have this controller assigned as their preferred path will be moved to the non-preferred path (alternate controller). This procedure will help you pinpoint the problem along the data path. Because the logical drives will be moved to the alternate controller, they should still be accessible. Therefore, no action is required on the individual logical drives.Possible causes include:∙The controller failed a manually initiated diagnostic test and was placed Offline.∙The controller was manually placed Offline using the Advanced>>Recovery>>Place Controller>>Offline menu option.∙There are disconnected or faulty cables.∙ A Hub or Fabric switch is not functioning properly.∙ A host adapter has failed.∙The storage subsystem contains a defective RAID controller.The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.CautionDo not replace the controller until you are instructed to do so. This procedure will instruct you to check the components along the connection, check the host adapters, and eventually instruct you to replace the controller, if necessary.CautionElectrostatic discharge can damage sensitive components. Use a grounding wrist strap or other anti-static precautions before removing or handling components.Important Notes∙When Auto Logical Drive Transfer (ADT) is enabled, it can take several minutes for the host-based, multi-path failover driver to recognize a restored or modified preferred path (use the Storage Subsystem Profile to determine whether you have ADT enabled on a mapped host; see Step 9 below). A Logical Drive Not On Preferred Path error will be reported during this time. If you have recently modified the preferred path using the Array>>Change>>Ownership/Preferred Path or Logical Drive>>Change>>Ownership/Preferred Path menu options or performed a recovery procedure that has restored a preferred path, wait at least 10 minutes and run the Recovery Guru again using the Recheck button. If this error is reported again, perform the recovery procedures listed below.∙Not all models of storage subsystems contain batteries. If your storage subsystem does not contain batteries, you can ignore any references to them in the following steps. To determine if your storage subsystem contains batteries, use the Storage Subsystem>>View Profile option and select the Enclosures tab. Storage Subsystems without batteries will not have those components listed.∙If the controllers for this storage subsystem are located in an enclosure containing both controllers and drives, you may have to insert the battery from the old controller canister into the new replacement controller canister. Consult the following steps and your hardware documentation for details.Recovery Steps12 Check the following components on both ends of the connection for loose connections or visible damage:∙External cables∙Hubs and switches3 Use the information in the following table to determine the action to take.4 Remove the defective controller. The defective controller (A or B) is listed in the Recovery Guru Details area.Note: Before you insert a new controller canister into an Out-of-Band Managed Storage Subsystem (refer to the Network Management Type column in the Enterprise Management Window), you must update the DHCP/BOOTP server so that it will associate the new controller's hardware Ethernet address with the host name and IP address previously assigned to the removed controller.To update the DHCP/BOOTP server, find the entry associated with the removed controller and replace its Ethernet address with the new controller's Ethernet address. The controller's Ethernet address is located on an Ethernet ID label on thecontroller canister in the form xx.xx.xx.xx.xx.xx. If you need more details, consult the Storage System Planning Guide .56 Make sure at least 1 minute has elapsed. Then, insert the new controller canister firmly into place.Note the controller slot (A or B) of the affected controller listed in the Recovery Guru Details area. Highlight this controller slot in the Physical View of the Subsystem Management Window.78 Note the controller slot (A or B) of the affected controller listed in the Recovery Guru Details area.
