运维过程中，有时需要快速查找HBA卡的WWN号，现把几种常见的系统下查找WWN号的方法总结一下。
AIX:
1,获得AIX主机连接的光纤设备:
# lsdev -Cc adapter -S a | grep fcs
fcs0 Available 09-08 FC Adapter
fcs1 Available 09-09 FC Adapter
其中,显示有两块光纤卡.fcs0和fcs1
2,查看光纤卡的WWN号
# lscfg -vpl fcs0
fcs0 U787B.001.DNWG664-P1-C1-T1 FC Adapter

其中标红的部分(Network Address)就是光纤卡的WWN号
HP-Unix:
1,列出HP机上连接的光纤卡设备:
# ioscan -fnC fc
Class I H/W Path Driver S/W State H/W Type Description
=================================================================
fc 0 0/3/1/0 fcd CLAIMED INTERFACE HP A6826-60001 2Gb Dual Port PCI/PCI-X Fibre Channel Adapter (FC Port 1)
/dev/fcd0
fc 1 0/3/1/1 fcd CLAIMED INTERFACE HP A6826-60001 2Gb Dual Port PCI/PCI-X Fibre Channel Adapter (FC Port 2)
/dev/fcd1
由此图可以看到,/dev/fcd0和/dev/fcd1是两个光纤卡
2, 查看光纤卡的WWN号
# fcmsutil /dev/fcd0
Vendor ID is = 0x001077
Device ID is = 0x002312
PCI Sub-system Vendor ID is = 0x00103c
PCI Sub-system ID is = 0x0012ba
PCI Mode = PCI-X 133 MHz
ISP Code version = 3.3.18
ISP Chip version = 3
Topology = PTTOPT_FABRIC
Link Speed = 2Gb
Local N_Port_id is = 0xa10500
Previous N_Port_id is = None
N_Port Node World Wide Name = 0x50060b00001db241
N_Port Port World Wide Name = 0x50060b00001db240
Switch Port World Wide Name = 0x205e000dec0e2e00
Switch Node World Wide Name = 0x2001000dec0e2e01
Driver state = ONLINE
Hardware Path is = 0/3/1/0
Maximum Frame Size = 2048
Driver-Firmware Dump Available = NO
Driver-Firmware Dump Timestamp = N/A
Driver Version = @(#) libfcd.a HP Fibre Channel ISP 23xx & 24xx Driver B.11.23.04 /ux/core/isu/FCD/kern/src/common/wsio/fcd_init.c:Oct 18 2005,08:21:11
其中红色部分显示了HBA卡的WWNN和WWPN号,另外还能看到该HBA卡连接的光纤交换机端口的WWN号
Solaris:
solaris上用luxadm命令来管理存储设备以及光纤相关设备.
1, 查询现有存储设备和光纤设备,可以读到包括磁盘设备的WWN号
# luxadm probe
2, 查看HBA的prot,可以得到HBA卡的port值以及连接属性:
# luxadm -e port
/devices/pci@0,0/pci1022,7450@2/pci1077,101@1/fp@0,0:devctl NOT CONNECTED
/devices/pci@0,0/pci1022,7450@2/pci1077,101@1,1/fp@0,0:devctl CONNECTED
从中可以看到仅有一块光纤卡连接到存储设备
3, 选择那个已经连接的HBA卡,查看其WWN号
格式: # luxadm -e dump_map 设备port.其中port值可从步骤2得到.如下图啊所示:
# luxadm -e dump_map /devices/pci@0,0/pci1022,7450@2/pci1077,101@1/fp@0,0:devctl
Pos Port_ID Hard_Addr Port WWN Node WWN Type
0 0 0 210000e08b19827a 200000e08b19827a 0x1f (Unknown Type,Host Bus Adapter)
Redhat:
在Redhat中,设备管理的相关信息都保存在内核中,即/proc目录.所以我们一般查询CPU,内存,磁盘等信息,也是在该目录下. 其中HBA卡相关信息保存在/proc/scsi/qlaxxx目录下,不同设备对应不同的文件名,例如
# grep scsi /proc/scsi/qla2300/1
Number of reqs in pending_q= 0, retry_q= 0, done_q= 0, scsi_retry_q= 0
scsi-qla0-adapter-node=200000e08b9cf661;
scsi-qla0-adapter-port=210000e08b9cf661;
就可以查到系统第一块HBA卡的WWNN和WWPN号.
CENTOS与SuSE Linux查看FC HBA卡信息的方法基本一致，在 /sys/class/fc_host/host*/port_name 这个文件包含了所有已被系统发现的FC HBA卡的信息，使用查看命令查看该文件的内容即可看到FC HBA卡的信息。
查看WWPN：cat /sys/class/fc_host/host*/port_name
查看WWNN：cat /sys/class/fc_host/host*/node_name
