UnityVSA是SUSE Linux Enterprise Server（SLES，如下） 12 SP1操作系统：

可以通过命令行来实现相关配置，如下图

UnityVSA控制台默认用户名和密码都为service，使用service/service登陆控制台，

spa login：service
Password：
14:08:40 service@VIRT1803SKN5YT-spa spa:~>

1、SSH服务开启设置

完成登陆后开始进行相关配置，首先为了能够使用SSH等相关工具来管理控制台，先开启SSH服务，使用help | more命令查看帮助：

14:11:30 service@VIRT1803SKN5YT-spa spa:~> help | more
The following UnityVSA serviceability commands are available to the service user:
svc_acldb_dump
svc_arrayconfig
svc_banner
svc_boot-control
svc_cache
svc_cava

最后查看到命令为svc_ssh，命令使用方法：

Usage: svc_ssh [options]
Options:
-e, –enable  Enable sshd on the system
-d,—disable Disables sshd on the system
-s,—status  Prints status of sshd
14:15:22 service@VIRT1803SKN5YT-spa spa:~>

使用svc_ssh –s查看目前的SSH状态，状态为disabled，关闭状态

14:16:54 service@VIRT1803SKN5YT-spa spa:~> svc_ssh –s

使用svc_ssh -e命令打开SSH功能：

14:18:33 service@VIRT1803SKN5YT-spa spa:~> svc_ssh –e

完成开启后，开始使用SecureCRT来管理控制台，如下图。

2、管理地址更改设置

首先使用svc_networkcheck –m命令查看当前的管理地址，如下

14:31:58 service@VIRT1803CVH590-spa spa:~> svc_networkcheck -m
=== SP status: Normal Mode, Master SP ===
======================= [spa][Mon Jan 22 14:32:05 UTC 2018] Beginning Run  =======================

Management IPv4 Information
        IP Address:                     192.168.10.59
        Mask/Prefix:                    255.255.255.0
        Gateway:                        192.168.10.253
DNS/NTP Information
        DNS server(s):                  None
        NTP server(s):                  None
Management IPv6 Information
DNS/NTP Information
        DNS server(s):                  None
        NTP server(s):                  None

======================= [spa][Mon Jan 22 14:32:19 UTC 2018] End of Run  =======================

接着，使用svc_initial_config命令修改管理IP地址，如下

14:32:21 service@VIRT1803CVH590-spa spa:~> svc_initial_config

Usage : svc_initial_config [OPTIONS]

Sets up initial system configuration. Configures a management IP address when the
Connection Utility (CU) is not available on the network. Can also be used to change
the management IPv4 and IPv6 configuration mode if an address is set.
                   
Attempts to configure the system with the given friendly name and/or network parameters.
Network parameters are for IPv4 and/or IPv6.

Ex: svc_initial_config [-f <hostname>] -4 "<IPv4 address> <IPv4 netmask> <IPv4 default gateway>"
     svc_initial_config [-f <hostname>] -6 "<IPv6 address> <prefix length> <IPv6 default gateway>"

Options:
  -h or –help       Prints this usage information.
  -4, –network      IPv4 address, netmask and default gateway for management interface.
                     MUST BE ENCLOSED BY "QUOTES" and given in that exact order:
                     "ip net_mask def_gw".
                     Use "auto" instead of "ip net_mask def_gw" for DHCP.
                     Use "disable" to disable IPv4 configuration.

  -6, –networkv6    IPv6 address, prefix length and default gateway for management interface.
                     MUST BE ENCLOSED BY "QUOTES" and given in that exact order:
                     "ip prefix_len def_gw".
                     Use "auto" instead of "ip prefix_len def_gw" to
                     enable IPv6 autoconfiguration.
                     Use "disable" to disable IPv6 configuration.
                      
  -f, –friendly_name  New friendly_name for the system. Name must contain only letters,
                       numbers, dot(.) or the hyphen(-) character.  Name must not start
                       nor end with a hyphen and be limited to a total length of
                       255 characters.
 
14:34:24 service@VIRT1803CVH590-spa spa:~> svc_initial_config -f unityvsanew -4 "192.168.10.57 255.255.255.0 192.168.10.253"
Attempting to set friendly name to <unityvsanew>
Successfully set friendly name to <unityvsanew>
Validating address 192.168.10.57 format … Pass
Validating address 255.255.255.0 format … Pass

Validating IP and Gateway subnet with Mask … Pass
Successfully configured network with parameters <static 192.168.10.57 255.255.255.0 192.168.10.253>

完成修改后，会出现Successfully提示，如上，成功后，就能使用新的地址来进行管理。

3、其它命令

UnityVSA与Unity存储平台均运行同样的Unity操作环境，它可以部署在VMware ESXi虚拟化平台上。EMC UnityVSA （Unity Virtual Storage Appliance）是运行在VMware ESXi平台上的软件定义统一存储。

UnityVSA提供4TB可用空间的社区版，以及10、25、50TB的专业版。如需更高的需求，请购买专业版本。

从EMC网站上下载OVA（百度云盘下载）文件UnityVSA-4.2.1.9535982.ova，上传至ESXI主机，准备部署

右键选择部署OVF模板

选择厚置备置零

完成部署后打开虚拟机电源，安装部署会有些时间，点击下图中的刷新图标，当出现DNS名称和IP地址（本例中为192.168.10.58）就说明已运行完成，可以通过https://192.168.10.58来访问Unisphere。

光纤交换机在远距离传输时对于光衰减有一定要求，当光纤衰减过大，两端的接口将不能UP。一般在-5dbm至+5db之间。如下图，以Cisco MDS 9124光纤交换机为例

进入设备的CONSOLE控制台，使用show interface fc x/x transceiver details命令可以查看某个端口的光衰减信息，以1/24为例，如下：

san-emc-01(config-if)# show interface fc 1/24 transceiver details 
fc1/24 sfp is present
    Name is OEM            
    Manufacturer’s part number is SFP-4G-ZX      
    Revision is 1.1
    Serial number is JUT102702FR    
    FC Transmitter type is long wave laser
    FC Transmitter supports long distance link length
    Transmission medium is single mode (SM) laser
    Supported speeds are – Min speed: 1000 Mb/s, Max speed: 4000 Mb/s
    Nominal bit rate is 4300 Mb/s
    Link length supported for 9/125mm fiber is 40.255 km
    Cisco extended id is unknown (0x0)

    No tx fault, no rx loss, in sync state, diagnostic monitoring type is 0x58
    SFP Diagnostics Information:
—————————————————————————-
                                     Alarms                  Warnings
                                High        Low         High          Low
—————————————————————————-
  Temperature  22.98 C        100.00 C    -45.00 C     95.00 C      -40.00 C
  Voltage       3.32 V          3.60 V      3.00 V      3.50 V        3.10 V
  Current      26.00 mA        80.00 mA    12.00 mA    75.00 mA      10.00 mA
  Tx Power     2.48 dBm        6.00 dBm   -5.00 dBm    5.00 dBm     -4.00 dBm
  Rx Power     -4.54 dBm       -1.00 dBm  -21.02 dBm   -2.00 dBm    -20.00 dBm
  Transmit Fault Count = 0
—————————————————————————-
  Note: ++  high-alarm; +  high-warning; –  low-alarm; -  low-warning

从上表中可以看出，Tx方向的衰减为2.48dBm，Rx的衰减为-4.54dBm，属于正常范围内。

以太网交换机也可以通过命令来查看光模块上的衰减，如H3C交换机，通过命令dis transceiver diagnosis interface G x/x/x来查看，如下：

[waiwang-center-h3c7510] dis transceiver diagnosis interface GigabitEthernet 0/0/6
GigabitEthernet0/0/6 transceiver diagnostic information:
  Current diagnostic parameters:
    Temp(°C)  Voltage(V)  Bias(mA)  RX power(dBm)  TX power(dBm)
    43              3.49            8.11          -5.18                 -4.71

华为交换机通过如下命令查看：

display transce inter g 1/0/23 version

华三交换机也可以通过以下命令查看光模块是否为真货，

[waiwang-center-h3c7510]dis transceiver manuinfo interface g0/0/30
GigabitEthernet0/0/30 transceiver manufacture information:
  Manu. Serial Number : 210231a562x08b009229
  Manufacturing Date  : 2008-11-22
  Vendor Name         : H3C

Vendor Name为H3C，即为真货。也可以去http://channel.h3c.com/channel/system/SearchTrueCode.jsp，输入上面显示的序列号，这里为210231a562x08b009229，来查询是否为真货。
