Dell Unity：如何使用 CLI 擴充 Unity 集區
Summary: 本文說明如何使用 Unity Enterprise Management CLI （UEMCLI），透過新增磁碟群組來擴充現有的 Dell Unity 儲存集區。該示例演示池擴展命令，包括所需的參數，如池ID、磁碟組ID、驅動器數和存儲配置檔。此程序可用來增加可用容量，同時維持所需的儲存分層和集區效能特性。

Instructions
1.檢查集區狀態，並取得磁碟機和 RAID 群組資訊：
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.根據需要和池要求插入驅動器。
3.在 Unisphere （UI） 中確認磁碟機是否為線上。
4.使用下列命令檢查包含未設定磁碟機的磁碟群組。此命令會顯示包含未設定磁碟機的磁碟群組。
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.使用此命令檢查要新增磁碟機的設定檔。此命令會顯示要新增磁碟機的設定檔，以根據 RAID 群組擴充集區。此外，請檢查屬於此設定檔的磁碟群組。
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.執行這個 uemcli 以擴展池的命令。在此範例中，磁碟群組為 dg_28，配置檔是 tprofile_1，待擴充集區的 ID 為 pool_1，而根據 RAID 群組，擴充集區的磁碟機數量為 5 個。在命令給出輸出後，顯示為 "Operation completed successfully."，請使用步驟 1 再次檢查驅動器數量和池狀態。
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
