<blockquote><p>AIX MPIO is supported on AIX starting from AIX 5.2 TL10, AIX 5.3 TL6 and AIX 6.1 SP2 though various PTFs and fixes may be required (see interoperability matrix and AIX MPIO documentation below). It is supported with DS4000 firmware 6.60.xx.xx and higher on DS4800, DS4700, DS4200, DS4500 and DS4300. MPIO is the strategic driver for all current DS4000 platforms in AIX 6.1 and up &#8211; except for DS4400 which is RDAC only. RDAC is the default driver on all levels of AIX 5.2 and 5.3.</p>
<p>In AIX Version 6.1, the DS4K products are configured as Multipath I/O (MPIO) devices by default. A DS4K product using the FCPARRAY (RDAC) driver may be migrated to the MPIO driver by using the instructions found in the documents below, or all DS4K devices may be migrated by uninstalling the devices.fcp.disk.array.rte package and then running the cfgmgr command or rebooting.</p></blockquote>

<p>如果你有很多TSM Server的可以安装：Integrated Solutions Console (ISC) and Administrative Center，类似IBM的HMC管理小型机，不太适合像我这样的字符控。AC6.2已经集成了ISC，不用再单独安装了，如下命令可以启动AC：</p>
<p>[root@TSMSRV bin]# cd /opt/ibm/ac/profiles/TIPProfile/bin</p>
<p>[root@TSMSRV bin]# ./startServer.sh server1 -username tipadmin -password tipadmin</p>

		<description><![CDATA[前段时间咱吃饭的家伙总是不厌其烦的报警：电脑温度过高，检查电脑散热部件。OK，我承认有一次手放在键盘上觉得好烫，背板绝对可以烧烤了，这让我下定决心给还只买1 year 10 month的它打扫打扫卫生，事后证明我的功课还做的不够到位啊。在动手之前，已经在网上下载了前人的拆卸图，心想：没吃过猪肉总看见过猪爬啊，依葫芦画瓢总会吧，再说咱也是吃过猪肉的啊。就这样时间选在了上周末下午，在键盘、掌托、硬盘、VGA的螺丝都拆了，看看灰尘还是很多的： 继续拆无线网络的天线、显示屏的排线，好，主板取下来了。接着要拆CPU的风扇，CPU的硅胶已经干了，这会严重影响导热性能，进一步拆风扇，用毛刷刷完灰后特别用空调清洁喷剂清洗铜片，擦干后又用天电吹风的冷风离了几十厘米吹了几十秒，这叫一个亮啊，一个字“爽”。涂完新的硅胶准备装配了，一个晴天霹雳暴风雨来了，瞟了一眼阳台，把咱上午的辛勤劳动成功快毁了，几个小时清洗橱柜的锅、碗、瓢、盆，衣服也淋到了。深圳的雨有一个特色，如果你在外面好赶上，打伞是没有用的，你以为躲在伞下就找不到你了？湿身真的无法避免，从里到外的湿。 集中精神开始装机了，熟能生巧这句一点不假，装想来快多了，开始机测试成果了。打开一个视频文件监控温度，效果非常好，风扇没有噪音了，CPU温度一直保持在50&#8242;C左右，嗯！收拾一下桌子，杯具开始了，桌子上多了一颗白色的螺丝，注意是白色的，这肯定是主板上哪里少装了一个，要不要装呢？抱着电脑摇动一下，听听声音，没有异响啊，装不装这个蛋疼的螺丝？不装，这不是我一惯做事的风格。此时，可以看到X200上有一个红色的圆圈，里面躺着一个‘拆’。完了，发现左、右、T键没反应了，唉啊，是不是键盘没接好，拆！-&#62;装！-&#62;没反应！ -&#62;拆！-&#62;装！ -&#62;没反应！ 拆&#8230;&#8230; 不拆了。经与同事的X200交换测试，键盘挂了。事情发展到现在，没办法了，咱也淘了一个传说中的原装正品今早装上了，表面上看与真正原装没啥两样，但手感没有之前的轻盈、有弹性了，当初就是冲键盘和散热买的ThinkPad，这下可好，为了散热换了键盘。 -The End-<table class="wumii-related-items" cellspacing="0" cellpadding="2" border="0" width="100%" style="clear: both;">

			<content:encoded><![CDATA[<p style="text-align: left;">前段时间咱吃饭的家伙总是不厌其烦的报警：电脑温度过高，检查电脑散热部件。OK，我承认有一次手放在键盘上觉得好烫，背板绝对可以烧烤了，这让我下定决心给还只买1 year 10 month的它打扫打扫卫生，事后证明我的功课还做的不够到位啊。在动手之前，已经在网上下载了前人的拆卸图，心想：没吃过猪肉总看见过猪爬啊，依葫芦画瓢总会吧，再说咱也是吃过猪肉的啊。就这样时间选在了上周末下午，在键盘、掌托、硬盘、VGA的螺丝都拆了，看看灰尘还是很多的：<br />
<img class="size-full wp-image-937" src="http://www.ochef.net/wp-content/uploads/2011/04/web001.jpg" alt="" width="400" height="265" /></p>
<p><img class="size-full wp-image-939 alignnone" src="http://www.ochef.net/wp-content/uploads/2011/04/web002.jpg" alt="" width="400" height="265" /></p>
<p>继续拆无线网络的天线、显示屏的排线，好，主板取下来了。接着要拆CPU的风扇，CPU的硅胶已经干了，这会严重影响导热性能，进一步拆风扇，用毛刷刷完灰后特别用空调清洁喷剂清洗铜片，擦干后又用天电吹风的冷风离了几十厘米吹了几十秒，这叫一个亮啊，一个字“爽”。涂完新的硅胶准备装配了，一个晴天霹雳暴风雨来了，瞟了一眼阳台，把咱上午的辛勤劳动成功快毁了，几个小时清洗橱柜的锅、碗、瓢、盆，衣服也淋到了。深圳的雨有一个特色，如果你在外面好赶上，打伞是没有用的，你以为躲在伞下就找不到你了？湿身真的无法避免，从里到外的湿。</p>
<p style="text-align: left;">集中精神开始装机了，熟能生巧这句一点不假，装想来快多了，开始机测试成果了。打开一个视频文件监控温度，效果非常好，风扇没有噪音了，CPU温度一直保持在50&#8242;C左右，嗯！收拾一下桌子，杯具开始了，桌子上多了一颗白色的螺丝，注意是白色的，这肯定是主板上哪里少装了一个，要不要装呢？抱着电脑摇动一下，听听声音，没有异响啊，装不装这个蛋疼的螺丝？不装，这不是我一惯做事的风格。此时，可以看到X200上有一个红色的圆圈，里面躺着一个‘拆’。完了，发现左、右、T键没反应了，唉啊，是不是键盘没接好，拆！-&gt;装！-&gt;没反应！ -&gt;拆！-&gt;装！ -&gt;没反应！    拆&#8230;&#8230;   不拆了。经与同事的X200交换测试，键盘挂了。事情发展到现在，没办法了，咱也淘了一个传说中的原装正品今早装上了，表面上看与真正原装没啥两样，但手感没有之前的轻盈、有弹性了，当初就是冲键盘和散热买的ThinkPad，这下可好，为了散热换了键盘。</p>

<p>解决方法：</p>
<p>在光纤交换机上运行以下命令来修改受影响的端口的一个参数。</p>
<p>portcfgfillword x 0</p>
<p>x 是受影响的端口号，例如 DS5020的A 控连在光纤交换机的 port 6上，那么x=6</p>
<p>修改完了后可以用“portcfgshow”命令来确认修改是否已经成功</p>

<p><strong>一、系统背景：</strong><strong> </strong></p>

<p>数据库：  Oracle 9.2.0.1.0  2 Nodes RAC  HA</p>
<p>备库P570（非DG）： 与DG原理类似，利用生产库的归档日志在P570上恢复</p>
<p>故障时间：2010-11-23  13:20</p>
<p><strong>二、故障现象：</strong><strong> </strong></p>
<p>数据库系统在13：19报告SYSTEM表空间空间不够无法自动扩展，因为系统使用RAW设备所以无法自动扩展，需要管理员手工增加RAW设备文件。</p>

<p>时间：16：00</p>
<p>由于系统数据量大，在生产库不能短时间恢复情况下的</p>
<p>措施：启动P570备库</p>
<p>结果：启动备库P570失败</p>
<p>原因：在10月19增加数据库文件/dev/rphoto1026时出错，需要恢复。</p>
<p>时间：16：20</p>
<p>措施：利用生产系统RMAN备份来恢复</p>
<p>结果：无法恢复</p>
<p>原因：每晚8点的定时备份任务在14日由于备份空间不足备份失败，后续没有任务备份；系统归档日志保留策略为7天，若要恢复到14日备份前，缺少1天的归档日志文件。</p>
<p><span id="more-908"></span> 时间：16：30</p>
<p>措施：向公司上级汇报情况，商议决策</p>
<p>结果：与Oracle原厂工程取得系统，商议决策如下：</p>
<p>1.      保护好生产系统现状</p>
<p>2.      使用操作系统级dd命令备份生产系统所有数据文件</p>
<p>3.      将备份的文件用dd命令恢复到备库P570</p>
<p>4.      在备库P570上做恢复测试</p>
<p>时间：24日2：30</p>
<p>措施：在P570备机上重建control file，剔除/dev/rwwwdb_system04数据文件，尝试打开数据库。</p>
<p>结果：open失败</p>
<p>原因：Oracle 9i 系统表空间数据文件不能真正删除（10g开始可以）。</p>
<p>再次如下恢复操作：</p>
<p>重新创建/dev/rwwwdb_system04文件</p>
<p>SQL&gt; alter database create datafile &#8216;/dev/rwwwdb_system04&#8242; as &#8216;/dev/rwwwdb_system04&#8242;;</p>
<p>结果：open成功</p>
<p><strong>三、生产系统恢复过程：</strong></p>
<p>1.      重建control file</p>
<p>获取重建控制文件的脚本，并修改相应部分</p>

<p>至此，生产系统数据库成功打开。</p>
<p>P670_1节点处理：</p>
<p>检查P670_1节点，发现主机访问DS4500存储系统上共享VG出现问题，为数据安全起见，先在P690_1节点备份数据库再处理P670_1节点。</p>
<p><strong>四、故障分析：</strong></p>
<p>在备份成功后，处理P670_1节点发现，DS4500存储系统B控制器坏掉，而引发了增加SYSTEM表空间失败。在更换存储系统控制器后，P670_1节点正常工作。</p>
<p><strong>五、改进与预防措施：</strong></p>
<p>1. 完善备份策略</p>
<p>2. 改善P570备库方式（采用rman备份归档日志，再恢复归档日志）</p>
<p>3. 每天检查生产系统的备份情况，及时发现问题及时处理。</p>
