Summary: Dell EMC Unity: Slik løser du problemet med Slett status: støttes ikke for VPlex klargjort Unity-volum (kan korrigeres av brukeren)
Symptoms
Dette gjelder VAAI UNMAP plug-in problemet, slette status vises ikke støttes:
[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
ELLER
hvis VPlex kjører på versjonen som støtter UNMAP-funksjonen for Unity, er årsaken at LUN-ene er tykke klargjort eller at LUN-ene er tynnklargjort på Unity, men tynnaktivert-funksjonen på VPlex virtuelt volum er deaktivert.
Resolution
Hvis VPlex ikke kjører på versjonen som støtter UNMAP-funksjonen for Unity. Kunden skal oppgradere VPlex til 6.0 SP 1, som støtter tynn UNMAP.
Ellers,
sjekker på VPlex
: 1. Kontroller om lagringsvolumet som leveres til VPlex, er tynt kompatibelt:

2. Kontroller om tynn aktivert funksjon på VPlex virtuelt volum er aktivert:VPlexcli:/clusters/cluster-1/virtual-volumes/testvolume_vol> ll

3. Aktiver tynnfunksjonen på det virtuelle volumet hvis den er deaktivert:VPlexcli:/clusters/cluster-1/virtual-volumes/testvolume_vol>set thin-enabled 1
Sjekker på ESXi :
4. Skann lagring på ESXi-serveren. Det kan gjøres både via kommandolinje og VCenter.[root@ESXi:/] esxcli storage core adapter rescan --all

6. Før du oppretter partisjon eller datalager på volumet, kan ESXi ikke få Thin Provisioning status for dette volumet, og dermed fortsatt rapporterer at funksjonen ikke støttes:

7. Opprett datalager på volumet eller opprett partisjonstabell manuelt for volumet, status for tynn klargjøring vil endres til ja og unmap vil 'endre til støttet'.[root@ESXi:/] esxcli storage core device list -d naa.6000144000000010b021768279d4285d

8. Etter å ha utført trinnene ovenfor, hvis ESXi fortsatt ikke oppdaterer unmap-statusen, kan du se etter VMware KBA og undersøke fra ESXi-siden.
