Dell Unity：如何使用 CLI 扩展 Unity 池
Summary: 本文介绍如何使用 Unity 企业管理 CLI （UEMCLI） 通过添加新磁盘组来扩展现有 Dell Unity 存储池。此示例演示了 pool extend 命令，其中包括所需的参数，例如池 ID、磁盘组 ID、驱动器数量和存储配置文件。该过程可用于增加可用容量，同时保持池所需的存储分层和性能特征。

Instructions
1.检查池的状态并获取驱动器和 RAID 组信息：
uemcli /stor/config/pool -name <pool_name> show -detail
Example:
14:11:25 service@xyz spb:~/user> uemcli /stor/config/pool -name XYZ123 show -detail
1: ID = pool_3
Type = Dynamic
Name = March2025
Description =
Total space = 3815810007040 (3.4T)
Current allocation = 20392058880 (18.9G)
Preallocated = 11551760384 (10.7G)
Remaining space = 3783866187776 (3.4T)
Subscription = 1182995120128 (1.0T)
Flash percent = 39%
Subscription percent = 31%
Alert threshold = 70%
Drives = 6 x 600.0G SAS; 6 x 400.0G SAS Flash 3
Number of drives = 12
RAID level = 5
Stripe length = 5
Rebalancing = no
Rebalancing progress =
Health state = Degraded/Warning (10)
Health details = "This storage pool exceeds the critical capacity threshold. Thin-provisioned resources may suffer data loss or become unavailable when the pool reaches full capacity. Snapshots may become invalid and replication sessions may stop synchronizing for storage resources provisioned in this pool. To allocate more storage space, add more disks to your system. (https://10.120.162.226/help/webhelp/en_US/index.html?#unity_c_storage_pool_at_or_near_full_capacity.html)"
2.根据需要和池要求插入驱动器。
3.在 Unisphere （UI） 中验证驱动器是否处于联机状态。
4.使用以下命令检查包含未配置驱动器的磁盘组。此命令显示包含未配置驱动器的磁盘组。
uemcli /stor/config/dg -traditional show
Example:
1: ID = dg_28
Drive type = SAS Flash 3
FAST Cache = no
Drive size = 1575700986880 (1.4T)
Vendor size = 1.6T
Rotational speed = 0 rpm
Number of drives = 43
Unconfigured drives = 7
Capacity = 67755142435840 (61.6T)
Recommended number of spares = 25.使用此命令检查要在其中添加驱动器的配置文件。此命令显示要在其中添加驱动器的配置文件，以便根据 RAID 组扩展池。此外，请检查属于此配置文件的磁盘组。
uemcli /stor/config/profile -traditional -configurable show
Example:
1: ID = tprofile_1
Type = Traditional
Description = SAS Flash RAID5 (4+1)
Drive type = SAS Flash
RAID level = 5
Maximum capacity = 7878504934400 (7.1T)
Stripe length = 5
Disk group = dg_28
Maximum drives to configure = 5
Maximum capacity to configure = 6302669729792 (5.7T)
6.运行此命令 uemcli 命令以扩展池。在此示例中，磁盘组为 dg_28，配置文件为 tprofile_1，则要扩展的池的 ID 为 pool_1，并且根据 RAID 组，扩展池的驱动器数量为 5。在命令给出输出后，输出为 "Operation completed successfully."，则使用步骤 1 再次检查驱动器数量和池状态。
uemcli -d 10.0.0.0 -u admin -p 'MyPassword123!' /stor/config/pool -id pool_1 extend -diskGroup dg_28 -drivesNumber 5 -storProfile tprofile_1
Example:
15:12:26 root@xyz spb:/cores/service/user> uemcli /stor/config/pool show -detail
Storage system address: 127.0.0.1
Storage system port: 443
