2. 配置扩展柜
这是配置扩展柜的，如果不需要扩展柜可以跳过这一步。5220默认已经有接近4.5T可用空间，一般是930T的硬盘，六块RAID6，两块RD1.
2.1扩展柜安装
注意：扩展柜安装可以在系统重灌之前或者之后进行；但是建议在重灌之前安装。初始化过程将自动创建dedup disk pool；如果初始化完成之后再添加扩展柜，需要手动创建dedup disk pool。
2.1.1 硬件连接
注意：将主柜SAS连接线分别接入扩展柜的IN口；扩展柜的OUT口用于连接第二个扩展柜的IN口。
连接图示（两个扩展柜）
注意：开启Appliance的时候先开扩展柜2-3分钟后，再开主柜。
2.1.2 添加扩展柜
1、用SSH登录到Appliance命令行菜单
注意：如果采用SecureCRT连接工具，可能要修改Authentication认证方式为Keyboard Interactive，否则系统将拒绝您登录；如下
2、转到manage->storage菜单，输入show，列出当前的存储信息，如下可以看出Uni_2是扩展柜，状态为New Available;
nb-appliance.Storage> show
----------------------------------------------------------------------------
Device | Total | Unallocated | Status
----------------------------------------------------------------------------
Appliance Operating System | 930.38 GB | - | In Use
Base Unit Storage (unit_1) | 4.5429 TB | 4.5419 TB | In Use
Expansion Unit Storage (unit_2) | 35.470 TB | - | New Available
NOTE: The name that appears in () (ex: unit_1) is the device name. Use the appropriate device name while issuing the commands to manipulate the storage.
----------------------------------------------------------------
Partition | Total | Available | Used | %Used
----------------------------------------------------------------
AdvancedDisk | 0 GB | 0 GB | 0 GB | 0%
Deduplication | 0 GB | 0 GB | 0 GB | 0%
Unallocated | 4.5419 TB | - | - | -
3、使用Add命令将扩展柜添加到系统
nb-appliance.Storage> Add
- [Info] Following expansion units can be added:
- [Info] unit_2
nb-appliance.Storage> Add unit_2
- [Info] Checking the type of the 'unit_2' device...
- [Info] Checking the state of the 'unit_2' expansion unit device storage...
- [Info] Initializing 'unit_2' expansion storage...
- [Info] Configuring 'unit_2' expansion unit storage...
- [Info] Adding 'unit_2' expansion unit storage space to 'Unallocated' space...
- [Info] Succeeded.
4、用show命令检查扩展柜是否已经被系统正常识别
nb-appliance.Storage> show
---------------------------------------------------------------------
Device | Total | Unallocated | Status
---------------------------------------------------------------------
Appliance Operating System | 930.38 GB | - | In Use
Base Unit Storage (unit_1) | 4.5429 TB | 4.5419 TB | In Use
Expansion Unit Storage (unit_2) | 35.470 TB | 35.470 TB | In Use
NOTE: The name that appears in () (ex: unit_1) is the device name. Use the appropriate device name while issuing the commands to manipulate the storage.
----------------------------------------------------------------
Partition | Total | Available | Used | %Used
----------------------------------------------------------------
AdvancedDisk | 0 GB | 0 GB | 0 GB | 0%
Deduplication | 0 GB | 0 GB | 0 GB | 0%
Unallocated | 40.012 TB | - | - | -
5、运行向导找到即可
