8、楚，在新的交换机上占用的端口号，回头要插入存储过来的光纤线，主机过来的光纤线，事先一定规划好，以免到时出乱。五：交换机切换下面分三种情况更换交换机，可以根据实际情况采取相应方式：（一）：在线更换交换机该方式不停应用，生产可以继续，但前提是一定要注意链路的冗余方式，至少2路，位于不同的交换机上。仔细核对主机里头的HDLM软件链路情况，删除先要更换的交换机所在的链路。1，如下，在每台主机上执行如下命令。确保另一链路的正常运行。5.8HDLM FOR AIX5.9以上HDLM FOR AIX2，此时系统单路运行，在插拔光纤线的时候，一定要注意，不能将剩下的一路offline，否则，应用会停，影响生产

9、。3，更换一路的交换机，重新cfgmgr ，识别链路正常后，更换另一路的交换机，方式如上。重新cfgmgr。识别新的硬件，硬盘。确保链路正常。验证应用。（二）：离线更换交换机，主机不重启1，停生产应用2，varyoffvg3，删除外接HDS的所有设备，两路全部删除掉命令如下：在每台主机上执行如下命令，删除2个fscsi，一般是fscsi0和fscsi1，两路全部删除5.8HDLM FOR AIX5.9以上HDLM FOR AIX更换两路的交换机，重新cfgmgr，识别新的硬件，硬盘。确保链路正常。（三）：离线更换交换机，主机重启1，停生产应用2，varyoffvg3，物理更换两路的交换机4，主

10、机重启，自动扫描新的硬件，确保两路链路正常六：验证，起服务，测试数据验证五中的后两种方式需要如下动作，第一种方式不需要。1，varyonvg2，起应用3，验证数据七：风险性评估，最优方式选取在步骤五中，提到了三种方式更换交换机，就风险性方面，建议采用（二）离线更换交换机，主机不重启，但如果主机数量较多，不能一一在主机执行相关的HDLM命令，则可以采用（三）离线更换交换机，主机重启，该方式彻底，一次性到位。不好处在于主机重启会耽误时间，有的主机重启可能需要漫长的等待时间，还可能重启后报硬件错误，这要注意。下面输出实际操作中的命令解析，采用（二）离线更换交换机，主机不重启，该情况为HDLM5.8

30、换完成后，cfgmgr，重新扫描硬件，会发现之前的盘又恢复为链路正常。如下：# ./dlnkmgr view -luProduct : 9500VSerialNumber : 4951LUs : 4iLU HDevName Device PathID Status0000 dlmfdrv2 hdisk8 000004 Online hdisk14 000005 Online0003 dlmfdrv3 hdisk10 000006 Online hdisk15 000007 Online0006 dlmfdrv0 hdisk6 000000 Online hdisk12 000001 Onlin

31、e0007 dlmfdrv1 hdisk7 000002 Online hdisk13 000003 Online关注点：按照英文手册里提供的是在线更换交换机，在该实例中：若：# ./dlnkmgr offline -hba 08.1H# ./dlmHBAdel fscsi0# rmdev -dl fscsi0 -R又执行：# ./dlnkmgr offline -hba 08.11此时HDLM软件会提示报错，因为当前动作是将两路的链路全部置为：offline(C)状态，HDLM软件出于安全保护的需要，因而会提示报错，警告当前操作危险，不能做，要至少保证一路链路是online状态的。那么，可以跳过该步骤，直接执行下一命令，如下：# ./dlmHBAdel fscsi1# rmdev -dl fscsi1 -R
