Solaris10上如何识别新增加的HDLM LUN

先在磁盘阵列上将新加LUN映射给主机组，然后在光纤交换机上增加相关zone信息。以下是Solaris10上需要执行的操作步骤。

• 在Solaris10上重新扫描磁盘

-bash-3.2# cfgadm -al

-bash-3.2# devfsadm -Cv

• format命令显示操作系统已经识别出新加lun

-bash-3.2# format

红色部分是新识别出来的lun信息。

• 重新生成HDLM配置文件

重新生成前最好备份一下原配置文件dlmfdrv.conf和dlmndrv.conf

-bash-3.2# dlmsetconf
KAPL10242-I To configure HDLM, device files of sd/ssd devices managed by HDLM are removed after reboot.
            Do you want to continue? [y/n]:y
KAPL10204-I dlmsetconf completed successfully.

• 检查HDLM配置文件

-bash-3.2# more /kernel/drv/dlmfdrv.conf
新加lun的信息已经自动加入到配置文件中。

• 使新HDLM配置文件生效

-bash-3.2# dlmcfgmgr -a
KAPL10373-I This operation will change the configuration of HDLM devices, and delete device files of sd/ssd devices managed by HDLM.
            Do you want to continue? [y/n]:y
KAPL10378-I The LU (LDEV = AMS.75040975.0050) was successfully added.

新增加的lun号是50。注意此处LUN50的第一条路径显示为"Online(E)"状态，其它路径均为“Offline(E)”。这并不表示LUN50路径有问题。在做完分区或创建文件系统后，路径会自动恢复为Online状态。

• 分区并label新加lun

在做完分区并label后路径状态正常

增加/删除路径、删除LUN的操作与新加LUN操作过程类似。
