Dell EMC Unity: Como resolver o problema "Delete Status: unsupported" para o volume Unity provisionado no VPlex (corrigível pelo usuário)
Summary: Dell EMC Unity: Como resolver o problema "Delete Status: unsupported" para o volume Unity provisionado no VPlex (corrigível pelo usuário)
Symptoms
Trata-se de um problema de plug-in UNMAP do VAAI. O status de exclusão mostra que não há suporte:
[root@ESXi:/] esxcli storage core device vaai status get -d naa.<WWN> VAAI Plugin Name: VMW_VAAIP_CX ATS Status: supported Clone Status: supported Zero Status: supported Delete Status: unsupported <<<<<<<<< The UNMAP feature became available for Unity arrays from VPLEX 6.0 Service Pack 1. So, must confirm if the VPlex is running on the correct version code that supports UNMAP. But, when the VPlex is running on the version that supports the UNMAP feature for Unity, the UNMAP feature reports unsupported. The use of UNMAP is limited to Thin provisioned volumes. So, need to check if the the LUNs are thin provisioned or not:
[root@ESXi:~] esxcli storage core device list -d naa.<WWN> <Output is truncated> . . Thin Provisioning Status: unknown <<<<<<< It means that the LUNs are thick provisioned
Cause
OU
Se o VPlex estiver em execução na versão compatível com o recurso UNMAP para Unity, a causa é que as LUNs têm provisionamento estático ou as LUNs têm provisionamento dinâmico no Unity, mas o recurso habilitado para thin no volume virtual do VPlex está desabilitado.
Resolution
Se o VPlex não estiver em execução na versão compatível com o recurso UNMAP para Unity. O cliente deve fazer upgrade do VPlex para a versão 6.0 SP 1, que é compatível com UNMAP dinâmico.
Caso contrário,
verifica o VPlex :
1. Verifique se o volume de armazenamento provisionado para o VPlex é compatível com thin:
VPlexcli:/clusters/cluster-1/storage-elements/storage-volumes> ll Name VPD83 ID Capacity Use Vendor IO Status Type Thin Provision Thin --------------------------------- ------------------------ -------- --------- ------- ----------- ----------- Rebuild Type Capable --------------------------------- ------------------------ -------- --------- ------- ----------- ----------- ------- --------- ------- VPD83T3:514f0c5b94e0002c VPD83T3:514f0c5b94e0002c 15G used Unity alive normal false legacy true
2. Verifique se o recurso dinâmico ativado no volume virtual do VPlex está ativado:VPlexcli:/clusters/cluster-1/virtual-volumes/testvolume_vol> ll

3. Ative o recurso thin no volume virtual, se ele estiver desabilitado:VPlexcli:/clusters/cluster-1/virtual-volumes/testvolume_vol>set thin-enabled 1
Verificações no ESXi :
4. Verificar o armazenamento no servidor ESXi. Isso pode ser feito tanto via linha de comando quanto pelo VCenter.[root@ESXi:/] esxcli storage core adapter rescan --all
5º. Execute o comando storage core path no VPlex virtual-volume Naa id i :[root@ESXi:/] esxcli storage core path list

6. Antes de criar uma partição ou um datastore no volume, o ESXi não consegue obter o status de provisionamento dinâmico para esse volume, portanto, ele ainda relata que o recurso não é compatível:

7. Crie um datastore no volume ou crie manualmente a tabela de partição para o volume. O status de provisionamento dinâmico mudará para sim e unmap "mudará para compatível".[root@ESXi:/] esxcli storage core device list -d naa.6000144000000010b021768279d4285d

8º. Depois de executar as etapas acima, se o ESXi ainda não atualizar o status de desmapeamento, verifique o KBA da VMware e investigue no ESXi.
