VNX应用实例：备件替换前如何查看零部件号VNX, EMC介绍本文档将介绍如何查看VNX设备P/N号(零部件号)，用来指导备件替换前查询P/N号的工作。
更多信息设备硬盘亮黄灯了，电源故障了，故障备件需要替换了，当然打800电话或开聊天支持窗口需求技术支持。
可EMC技术工程师说备件故障需要P/N号(零部件号)才能派备件，不然就只有让EMC现场工程师上门查询P/N号(零部件号)派备件了，因此学会在VNX上查看P/N 号(零部件号)是非常实用的技巧。
P/N号和S/N号的区别P/N是英文Part Number的缩写，也就是：零(部)件号。
代表出厂批次，这些才是代表产品型号。
S/N是英文Serial Number的缩写，也就是：序列号。
代表出厂编号，是独一无二的号码。
上面的定义就能解释为什么EMC技术支持工程师需要详细的P/N号才能派备件，而不是S/N号。
查询P/N号的步骤在VNX可以通过命令行登录到control station查看到配件P/N号，下面进行介绍：第一步：使用用户nasadmin登录到control station;第二步：使用命令nas_inventory–list列出所有备件设备：[nasadmin@VNX5500-QQ50-CS ~]$ nas_inventory -listComponent Type Status System IDControl Station 0 Control Station OK VNX VNX5500 FNM001041000302007DME 0 Enclosure OK VNX VNX5500 FNM001041000302007DME 0 Blower A Blower OK VNX VNX5500 FNM001041000302007DME 0 Blower B Blower OK VNX VNX5500 FNM001041000302007DME 0 Blower C Blower OK VNX VNX5500 FNM001041000302007DME 0 Blower D Blower OK VNX VNX5500 FNM001041000302007DME 0 Data Mover 2 Data Mover OK VNX VNX5500 FNM001041000302007DME 0 Data Mover 2 DIMM 0 DIMM OK VNX VNX5500 FNM001041000302007DME 0 Data Mover 2 DIMM 1 DIMM OK VNX VNX5500 FNM001041000302007DME 0 Data Mover 2 DIMM 2 DIMM OK VNX VNX5500 FNM001041000302007DME 0 Data Mover 2 DIMM 3 DIMM OK VNX VNX5500 FNM001041000302007DME 0 Data Mover 2 DIMM 4 DIMM OK VNX VNX5500 FNM001041000302007DME 0 Data Mover 2 DIMM 5 DIMM OK VNX VNX5500 FNM001041000302007[nasadmin@VNX5500-QQ50-CS ~]$第三步：使用命令nas_inventory–list –location列出备件的位置：[nasadmin@VNX5500-QQ50-CS ~]$ nas_inventory -list -locationComponent Type Status System ID LocationControl Station 0 Control Station OK VNX VNX5500 FNM001041000302007 system:VNX5500:FNM001041000302007|controlStation::0DME 0 Enclosure OK VNX VNX5500 FNM001041000302007 system:VNX5500:FNM001041000302007|enclosure:xpe:0DME 0 Blower A Blower OK VNX VNX5500 FNM001041000302007 system:VNX5500:FNM001041000302007|enclosure:xpe:0|Blower::ADME 0 Blower B Blower OK VNX VNX5500 FNM001041000302007 system:VNX5500:FNM001041000302007|enclosure:xpe:0|Blower::BDME 0 Blower C Blower OK VNX VNX5500 FNM001041000302007 system:VNX5500:FNM001041000302007|enclosure:xpe:0|Blower::CDME 0 Blower D Blower OK VNX VNX5500 FNM001041000302007 system:VNX5500:FNM001041000302007|enclosure:xpe:0|Blower:DME 0 Data Mover 2 Data Mover OK VNX VNX5500 FNM001041000302007 system:VNX5500:FNM001041000302007|enclosure:xpe:0|mover:VNX5500:2DME 0 Data Mover 2 DIMM 0 DIMM OK VNX VNX5500 FNM001041000302007 system:VNX5500:FNM001041000302007|enclosure:xpe:0|mover:VNX5500:2|dimm::0 DME 0 Data Mover 2 DIMM 1 DIMM OK VNX VNX5500 FNM001041000302007 system:VNX5500:FNM001041000302007|enclosure:xpe:0|mover:VNX5500:2|dimm::1 DME 0 Data Mover 2 DIMM 2 DIMM OK VNX VNX5500 FNM001041000302007 system:VNX5500:FNM001041000302007|enclosure:xpe:0|mover:VNX5500:2|dimm::2 DME 0 Data Mover 2 DIMM 3 DIMM OK VNX VNX5500 FNM001041000302007 system:VNX5500:FNM001041000302007|enclosure:xpe:0|mover:VNX5500:2|dimm::3 DME 0 Data Mover 2 DIMM 4 DIMM OK VNX VNX5500 FNM001041000302007 system:VNX5500:FNM001041000302007|enclosure:xpe:0|mover:VNX5500:2|dimm::4 DME 0 Data Mover 2 DIMM 5 DIMM OK VNX VNX5500 FNM001041000302007 system:VNX5500:FNM001041000302007|enclosure:xpe:0|mover:VNX5500:2|dimm::5 [nasadmin@VNX5500-QQ50-CS ~]$第四步：使用命令nas_inventory -info { -all | }查看具体备件的PN号。

MPIO CHOICES The two primary forms of server MPIO are network-based and storage-based. Network-based MPIO (teaming or trunking) offers failover and rudimentary load balancing; performance is limited because only a single physical link can be used for any single TCP/IP connection at one time. Network-based MPIO supports software initiators with NICs or TOEs, but not HBAs, and special network setup is required. Network and switch configurations are restricted, and certain network management features must be disabled. Since these solutions load balance using random I/O distribution with no awareness of link status, network operations can be less efficient.Storage-based MPIO offers a more powerful, flexible, and efficient solution, and works with any mix of NICs, TOEs, and HBAs. This method requires no special network hardware setup or network configuration — a host can leverage multiple connections to any number of storage devices. It does require that servers be configured so that each host connection can use all available paths. This solution also supports a rich variety of load balancing algorithms, including active-active, minimum queue, active-passive, fastest response time, etc.SAN PATH BALANCING – AN MPIO IMPLEMENTATION CHALLENGE In SAN configurations, many connections from host to switches feed into fewer connections from switches to storage. It is common for 10 hosts to be connected to a single storage array through the SAN; this can be a natural bottleneck. But with MPIO, you can manage the paths in both halves of your architecture — from server to switch and from switch to storage —eliminating the congestion.For optimal operation, all network paths between the host and the storage must be balanced. Multi-path software on the hosthandles the host-to-switch connection,but how are the switch-to-storage connections balanced? In many solutions this is a manual task, which typically increases the administrative burden and decreases operational efficiency. It is also a job that is never-ending, as workloads change constantly.DELL ™ EQUALLOGIC ™ PS SERIES ARRAYS ADD AUTOMATION FOR MPIO ENVIRONMENTSPS Series arrays simplify multi-path management by automatically monitoring and load balancing I/O across multiple host and storage connections — online, continuously, without disrupting servers. Intelligent SAN balancing can significantly improve the quality of load balancing, as path activity levels can be monitored and I/O loads shifted from heavily trafficked to less congested paths. In addition, EqualLogic arrays include automated host connection management, simplifying the host setup while ensuring that each server can use all available paths. The potential result: optimal performance automatically throughout the entire data path; improved performance for all applications; and easy management. As you add arrays, automatic load balancing extends across all arrays for outstanding performance.MPIO – HELPING YOU GET THE MOST OUT OF YOUR SANMulti-path I/O lets you enhance the performance and availability of your infrastructure in an iSCSI SAN. PS Series arrays provide a redundant and hot swappable architecture, automatic monitoring and load balancing, and the ability to scale on demand.S I M PL I F YY O URS T O R A GEA T© 2009 Dell Inc.CB107_USA_020108_071409Network-based MPIO delivers some failover and load balancing, but is more complex to set up and manage. Storage-based MPIO offers more advanced functionality with fewer restrictions.。
