問題：無法從 UI 擴充集區。
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.根據需求插入磁碟機。檢查 RAID 群組並視需要插入磁碟機以擴充集區。
3.使用以下命令檢查磁碟機是否為線上狀態：
fbecli.exe
pdo
這些命令會顯示磁碟機數量以及處於線上狀態的磁碟機。將此輸出與上述輸出相符，以判斷
pdo 輸出具有比集區更多的驅動器。
4.使用此命令檢查包含未設定磁碟機的磁碟群組：
uemcli /stor/config/dg -traditional show
此命令會顯示包含未設定磁碟機的磁碟群組。
範例：
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 = 2- 使用此命令檢查要新增磁碟機的設定檔：
uemcli /stor/config/profile -traditional -configurable show
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。
例：
例：
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)
- 執行 uemcli 命令以擴充集區：
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
就上述範例而言，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。
例：
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
