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

======================= [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 address 192.168.10.253 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。
