AIX:
1,獲得AIX主機連接的光纖設備:
root@test:/# lsdev -Cc adapter -S a |grep fcs fcs0 Available 05-00 4Gb FC PCI Express Adapter (df1000fe) fcs1 Available 05-01 4Gb FC PCI Express Adapter (df1000fe) fcs2 Available 04-00 4Gb FC PCI Express Adapter (df1000fe) fcs3 Available 04-01 4Gb FC PCI Express Adapter (df1000fe)
顯示光纖卡的數量
2,查看光纖卡的WWN號:
root@test:/# lscfg -vpl fcs0 fcs0 U78AA.001.WZSGZ30-P1-C5-T1 4Gb FC PCI Express Adapter (df1000fe) Part Number.................10N7255 Serial Number...............1A1490164A Manufacturer................001A EC Level....................D77040 Customer Card ID Number.....5774 FRU Number..................10N7255 Device Specific.(ZM)........3 Network Address.............10000000C9CC8A2E #wwn地址 ROS Level and ID............02E8277F Device Specific.(Z0)........2057706D Device Specific.(Z1)........00000000 Device Specific.(Z2)........00000000 Device Specific.(Z3)........03000909 Device Specific.(Z4)........FFE01212 Device Specific.(Z5)........02E8277F Device Specific.(Z6)........06E12715 Device Specific.(Z7)........07E1277F Device Specific.(Z8)........20000000C9CC8A2E Device Specific.(Z9)........ZS2.71X15 Device Specific.(ZA)........Z1F2.70A5 Device Specific.(ZB)........Z2F2.71X15 Device Specific.(ZC)........00000000 Hardware Location Code......U78AA.001.WZSGZ30-P1-C5-T1 PLATFORM SPECIFIC Name: fibre-channel Model: LPe11002 Node: fibre-channel@0 Device Type: fcp Physical Location: U78AA.001.WZSGZ30-P1-C5-T1 root@test:/#
HP-Unix:
1,列出HP機上連接的光纖卡設備:
# ioscan -fnC fc Class I H/W Path Driver S/W State H/WType Description ============ fc 0 0/3/1/0 fcd CLAIMED INTERFACE HP A6826-600012Gb Dual Port PCI/PCI-X Fibre Channel Adapter (FC Port 1) /dev/fcd0 fc 1 0/3/1/1 fcdCLAIMED INTERFACE HP A6826-60001 2GbDual Port PCI/PCI-X Fibre Channel Adapter (FC Port 2) /dev/fcd1
由此圖可以看到,/dev/fcd0和/dev/fcd1是兩個光纖卡
2, 查看光纖卡的WWN號
# fcmsutil /dev/fcd0 Vendor ID is = 0x001077 Device ID is = 0x002312 PCISub-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 PortWorld Wide Name = 0x50060b00001db240 Switch PortWorld Wide Name = 0x205e000dec0e2e00 Switch NodeWorld 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 DriverB.11.23.04 /ux/core/isu/FCD/kern/src/common/wsio/fcd_init.c:Oct 18 2005,08:21:11
顯示了HBA卡的WWNN和WWPN號,另外還能看到該HBA卡連接的光纖交換機端口的WWN號
Solaris:
solaris上用luxadm命令來管理存儲設備以及光纖相關設備.
1, 查詢現有存儲設備和光纖設備,可以讀到包括磁盤設備的WWN號
# luxadm probe
2, 查看HBA的prot,可以得到HBA卡的port值以及連接屬性:
# 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
從中可以看到僅有一塊光纖卡連接到存儲設備
3, 選擇那個已經連接的HBA卡,查看其WWN號
格式: # luxadm -edump_map 設備port.其中port值可從步驟2得到.如下圖啊所示:
# 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,設備管理的相關信息都保存在內核中,即/proc目錄.所以我們一般查詢CPU,內存,磁盤等信息,也是在該目錄下. 其中 HBA卡相關信息保存在/proc/scsi/qla2300/目錄下,不同設備對應不同的文件名,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;
HBA卡里面的Node WWN 和Port WWN
HBA,字面理解是主機總線適配卡,我覺得現在狹義的叫做 FC HBA,在的HBA也就是Fibre Channel HostBus Adapter,因為網卡是不是也可以叫做NETWORK HBA呢,在FC網絡中,主機(如服務器)需要和FC網絡、FC存儲設備(如SAN)連接時,需要使用一種接口卡,就如同連接以太網需要以太網卡一樣。這 種接口卡就叫做FC HBA,簡稱HBA
和以太網卡的MAC地址一樣,HBA上也有獨一無二的標識,這就是WWN(World Wide Name)。HBA上的WWN有兩種:
Node WWN(WWNN):每個HBA有其獨有的Node WWN
一般在solaris里面用
#luxadm probe
得到的結果都是NODE WWN。根據有幾個NODE WWN,你就可以知道你有幾個FC HBA卡了。
Port WWN(WWPN):HBA卡上每個port有其獨一無二的Port WWN。
由于通訊是通過port進行的,多數情況下需要使用WWPN而不是WWNN。
WWN的長度為8bytes,用16進制表示并用冒號分隔。例如:50:06:04:81:D6:F3:45:42
