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 Searching for disks...done c2t50060E80102A00F0d1: configured with capacity of 9.96GB c2t50060E80102A00F3d1: configured with capacity of 9.96GB c3t50060E80102A00F1d1: configured with capacity of 9.96GB c3t50060E80102A00F2d1: configured with capacity of 9.96GB AVAILABLE DISK SELECTIONS: 0. c1t0d0 <SUN146G cyl 14087 alt 2 hd 24 sec 848> /pci@0/pci@0/pci@2/scsi@0/sd@0,0 1. c1t1d0 <HITACHI-H101414SCSUN146G-SA25 cyl 14087 alt 2 hd 24 sec 848> /pci@0/pci@0/pci@2/scsi@0/sd@1,0 2. c1t2d0 <HITACHI-H101414SCSUN146G-SA25 cyl 14087 alt 2 hd 24 sec 848> /pci@0/pci@0/pci@2/scsi@0/sd@2,0 3. c2t50060E80102A00F0d1 <HITACHI-DF600F-0000 cyl 544 alt 2 hd 50 sec 768> /pci@0/pci@0/pci@8/pci@0/pci@1/QLGC,qlc@0/fp@0,0/ssd@w50060e80102a00f0,1 4. c2t50060E80102A00F3d1 <HITACHI-DF600F-0000 cyl 544 alt 2 hd 50 sec 768> /pci@0/pci@0/pci@8/pci@0/pci@1/QLGC,qlc@0/fp@0,0/ssd@w50060e80102a00f3,1 5. c3t50060E80102A00F1d1 <HITACHI-DF600F-0000 cyl 544 alt 2 hd 50 sec 768> /pci@0/pci@0/pci@9/QLGC,qlc@0/fp@0,0/ssd@w50060e80102a00f1,1 6. c3t50060E80102A00F2d1 <HITACHI-DF600F-0000 cyl 544 alt 2 hd 50 sec 768> /pci@0/pci@0/pci@9/QLGC,qlc@0/fp@0,0/ssd@w50060e80102a00f2,1 7. c4t50060E80102A00F0d0 <HITACHI-DF600F-0000 cyl 48820 alt 2 hd 255 sec 189> /pseudo/dlmndrv@1/dlmfdrv@w50060e80102a00f0,0 Specify disk (enter its number):

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.
KAPL10370-I dlmcfgmgr completed successfully.

• 检查LUN信息

-bash-3.2# dlnkmgr view -lu
Product       : AMS
SerialNumber  : 75040975
LUs           : 2

iLU  HDevName              Device PathID Status
0049 c4t50060E80102A00F0d0 ssd0   000000 Online
                           ssd1   000001 Online
                           ssd3   000002 Online
                           ssd2   000003 Online

KAPL01001-I The HDLM command completed normally. Operation name = view, completion time = 2014/04/14 10:30:02

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

-bash-3.2# dlnkmgr view -lu
Product       : AMS
SerialNumber  : 75040975
LUs           : 2

iLU  HDevName              Device PathID Status
0049 c4t50060E80102A00F0d0 ssd0   000000 Online
                           ssd1   000001 Online
                           ssd3   000002 Online
                           ssd2   000003 Online

KAPL01001-I The HDLM command completed normally. Operation name = view, completion time = 2014/04/14 10:32:28

增加/删除路径、删除LUN的操作与新加LUN操作过程类似。
