红色部分是新识别出来的lun信息。

重新生成HDLM配置文件

-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
