故障排除提示

检查vHBA有FLOGI到SAN结构。

  1. 登录到UCS CLI并且连接对NXOS。

    # connect nxos a|b
    (nxos)# show npv flogi-table

    http://www.cisco.com/c/dam/en/us/support/docs/servers-unified-computing/ucs-b-series-blade-servers/115764-ucs-san-tshoot-01.gif

    确保WWPN的FCID分配,并且VSAN正确。

  2. 或者,从Cisco MDS交换机,请检查WWPN有FLOGI。

    SV-35-06-MDS9222i# show flogi database
    SV-35-06-MDS9222i# show fcns database

检查在MD交换机的区域确保, vHBA(WWPN)和存储设备目标联机和在同一个区域。

SV-35-06-MDS9222i# show zoneset active vsan 1000

http://www.cisco.com/c/dam/en/us/support/docs/servers-unified-computing/ucs-b-series-blade-servers/115764-ucs-san-tshoot-02.gif

检查vHBA是否能看到在SAN期间的目标启动。

在UCS管理器,如果刀片能从SAN启动,然后UCS管理器“实际引导程序命令”应该能发现所有目标WWPN。

http://www.cisco.com/c/dam/en/us/support/docs/servers-unified-computing/ucs-b-series-blade-servers/115764-ucs-san-tshoot-03.gif

当启动刀片时,请按F2输入BIOS和导航对引导程序管理器。BIOS应该能发现LUN启动。

http://www.cisco.com/c/dam/en/us/support/docs/servers-unified-computing/ucs-b-series-blade-servers/115764-ucs-san-tshoot-04.gif

对于PALO适配器,在此阶段(当OS未开始)时,您能也连接到适配器证实vHBA是否有FLOGI和PLOGI。

http://www.cisco.com/c/dam/en/us/support/docs/servers-unified-computing/ucs-b-series-blade-servers/115764-ucs-san-tshoot-05.gif

在OS有启动后,输出不同的。这预计。

http://www.cisco.com/c/dam/en/us/support/docs/servers-unified-computing/ucs-b-series-blade-servers/115764-ucs-san-tshoot-06.gif

对于M71KR-E适配器,当启动服务器时,请按输入Emulex HBA配置工具的控制+ E。然后,请选择vHBA并且列出引导设备。vHBA应该能发现目标。

http://www.cisco.com/c/dam/en/us/support/docs/servers-unified-computing/ucs-b-series-blade-servers/115764-ucs-san-tshoot-07.gif

检查vHBA是否有正确的LUN ID启动从SAN。

引导程序策略关联与服务档案有引导配置。确保目标的WWPN正确,并且LUN ID也匹配在存储设备定义的LUN。

http://www.cisco.com/c/dam/en/us/support/docs/servers-unified-computing/ucs-b-series-blade-servers/115764-ucs-san-tshoot-08.gif

其次示例为EMC存储设备。在存储设备组中, LUN 1301被映射到有ID的0主机,必须匹配在引导程序策略定义的ID。

http://www.cisco.com/c/dam/en/us/support/docs/servers-unified-computing/ucs-b-series-blade-servers/115764-ucs-san-tshoot-09.gif

检查FC目标是否能看到vHBA(WWPN),并且是否有PLOGI到目标。

http://www.cisco.com/c/dam/en/us/support/docs/servers-unified-computing/ucs-b-series-blade-servers/115764-ucs-san-tshoot-10.gif

检查思科是否定制ESXi镜像使用SAN启动。

如果ESXi不能发现在SAN的LUN,当vHBA在引导程序阶段时看到LUN,是可能的ESXi镜像没有正确驱动程序。证实客户是否使用思科定制的ESXi镜像。去VMware网站和搜索“思科的ESXi”下载思科定制的镜像。

思科定制ESXi的5.1.0镜像

https://my.vmware.com/web/vmware/details?downloadGroup=CISCO-ESXI-5.1.0-GA-25SEP2012&productId=285

思科定制ESXi的镜像5.0.0 U1

https://my.vmware.com/web/vmware/details?downloadGroup=CISCO-ESXI-5.0.0-U1-28AUG2012&productId=268

思科定制ESXi的镜像4.1 U2

https://my.vmware.com/web/vmware/details?downloadGroup=OEM-ESXI41U2-CISCO&productId=230

vSphere 5.0 Rollp ISO镜像(提供包括VMware合作伙伴导致的多种产品的驱动程序)的一可安装的ESXi ISO镜像,例如与C220 M3服务器, CIMC 1.46c和LSI 9266-8i。定制的ESXi镜像没有检测的驱动程序局部存储器。

https://my.vmware.com/web/vmware/details?downloadGroup=ROLLUPISO_50_2&productId=229

并且,参考纵向分配版本注释

http://www.vmware.com/support/vsphere5/doc/vsphere-esxi-50-driver-rollup2-release-notes.html

检查ESXi是否使用同一正确fnic驱动程序。

启用SSH和ESX SHELL和登录到ESXi主机。然后,请运行vmkload_mod – fnic的s。

http://www.cisco.com/c/dam/en/us/support/docs/servers-unified-computing/ucs-b-series-blade-servers/115764-ucs-san-tshoot-11.gif

检查主机是否能看到所有路径到从VMware ESXi的存储设备目标。

  1. 检查能由所有vHBA看到的LUN信息。

    ~ # esxcfg-scsidevs -c
    Device UID                            Device Type      Console 
    Device                                 Size             Multipath PluginDisplay Name

    1f0280000e47af49150e111)
    naa.6006016081f028007a6ffec12985e111  Direct-Access    /vmfs/devices/disks/naa.600601
    6081f028007a6ffec12985e111  51200MB   NMP     DGC Fibre Channel Disk (naa.6006016081f
    028007a6ffec12985e111)
    naa.6006016081f02800ca79c3b09150e111  Direct-Access    /vmfs/devices/disks/naa.600601
    6081f02800ca79c3b09150e111  10240MB   NMP     DGC Fibre Channel Disk (naa.6006016081f
    02800ca79c3b09150e111)
  2. 检查哪vHBA能看到哪LUN。

    ~ # esxcfg-scsidevs -A
    vmhba1      naa.6006016081f0280000e47af49150e111
    vmhba1      naa.6006016081f028007a6ffec12985e111
    vmhba1      naa.6006016081f02800ca79c3b09150e111
    vmhba2      naa.6006016081f0280000e47af49150e111
    vmhba2      naa.6006016081f028007a6ffec12985e111
    vmhba2      naa.6006016081f02800ca79c3b09150e111

    在本例中以上示例, vmhba1和vmhba2能看到3 LUN。

  3. 检查路径对LUN。
