Problema: No se puede expandir un grupo desde la interfaz de usuario.

 

1. Compruebe el estado del pool y obtenga la información de la unidad y del grupo 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. Inserte las unidades según los requisitos. Compruebe el grupo RAID e inserte unidades para expandir el pool según sea necesario.

3. Compruebe si las unidades están en línea con estos comandos:       

fbecli.exe
pdo
 
Estos comandos muestran la cantidad de unidades y el estado de las unidades que están en línea. Una esta salida con la anterior para determinar si la pdo La salida tiene más unidades que el pool.
 
4. Compruebe el grupo de discos que contiene las unidades no configuradas con este comando:       
uemcli /stor/config/dg -traditional show
 
Este comando muestra el grupo de discos que contiene las unidades no configuradas.

Ejemplo:      
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. Compruebe el perfil donde se agregarán las unidades con este comando:     
uemcli /stor/config/profile -traditional -configurable show
 
Este comando muestra el perfil en el que se agregarán las unidades para expandir el pool según el grupo RAID. Además, compruebe el grupo de discos que pertenece a este perfil.

Ejemplo:      
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. Ejecute el comando uemcli para expandir el grupo:      
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
 
En el ejemplo anterior, el grupo de discos es dg_28, el perfil es tprofile_1, el ID del pool que se expandirá es pool_1y la cantidad de unidades para expandir el pool es 5 según el grupo RAID.

Después de que el comando da el resultado como "Operation completed successfully.", vuelva a comprobar el número de unidades y el estado del pool mediante el paso 1.

Ejemplo:      
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
