Problema: Não é possível expandir um pool a partir da interface do usuário.

 

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. Verifique o grupo RAID e insira unidades para expandir o pool conforme necessário.

3. Verifique se as unidades estão on-line com estes comandos:       

fbecli.exe
pdo
 
Esses comandos exibem o número de unidades e o status das unidades que estão on-line. Faça a correspondência entre esse resultado e o resultado acima para determinar se o pdo O resultado tem mais unidades do que o pool.
 
4. Verifique o grupo de discos que contém as unidades não configuradas com este comando:       
uemcli /stor/config/dg -traditional show
 
Esse comando mostra o grupo de discos que contém as unidades não configuradas.

Exemplo:      
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
  1. Verifique o perfil onde as unidades serão adicionadas com este comando:     
uemcli /stor/config/profile -traditional -configurable show
 
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.

Exemplo:      
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)

 

  1. Execute o comando uemcli para expandir o pool:      
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
 
No exemplo acima, 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.

Exemplo:      
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
