HBA卡更换步骤

HBA卡更换步骤：

确认HBA卡的位置

从当前收到的错误信息看，fget_config的输出如下：

mjplm01>#fget_config -Av

---dar0---

User array name = ''

dac3 ACTIVE dac2 ACTIVE

Disk DAC LUN Logical Drive

utm 31

hdisk2 dac3 0 db1

hdisk3 dac3 1 1

hdisk4 dac3 2 db3

所有的lun都切换到dac3控制器上了。

在errpt中有很多dac2的报错，报错信息如下：

mjplm01#errpt -dH|more

结合lsdev的信息，可以判断出dac2在光纤卡fcs0的通道上。

mjplm01>#lsdev -C|grep dac

在换卡之前首先要确认故障光线卡的物理位置。如果换错了光纤卡会造成灾难性的后果，所以一定要谨慎小心，反复确认。

fcs0卡的信息如下：
