Dell Unity: Como expandir um pool do Unity usando a CLI
Summary: Este artigo explica como usar a UEMCLI (Unity Enterprise Management CLI) para expandir um pool de armazenamento existente do Dell Unity adicionando um novo grupo de discos. O exemplo demonstra o comando de extensão do pool, incluindo os parâmetros necessários, como o ID do pool, o ID do grupo de discos, o número de unidades e o perfil de armazenamento. O procedimento pode ser usado para aumentar a capacidade disponível e, ao mesmo tempo, manter a classificação de armazenamento por níveis e as características de desempenho desejadas do pool. ...

Instructions
1. Verifique o status do pool e obtenha as informações da unidade e do grupo de RAID:
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. Insira as unidades de acordo com a necessidade e os requisitos de pool.
3. Verifique se as unidades estão on-line no Unisphere (UI).
4. Verifique o grupo de discos que contém as unidades não configuradas com o seguinte comando. Esse comando mostra o grupo de discos que contém as unidades não configuradas.
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. Verifique o perfil no qual as unidades serão adicionadas com esse comando. Esse comando exibe o perfil ao qual as unidades serão adicionadas para expandir o pool de acordo com o grupo de RAID. Além disso, verifique o grupo de discos que pertence a esse perfil.
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. Execute isto uemcli Comando para expandir o pool. Neste exemplo, o grupo de discos é dg_28, o perfil é tprofile_1, o id do pool a ser expandido é pool_1e o número de unidades para expandir o pool é 5, de acordo com o grupo de RAID. Depois que o comando fornece o resultado como: "Operation completed successfully.", verifique o número de unidades e o status do pool novamente usando a Etapa 1.
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
