how to take snapshot VM with RDM and physical bus sharing

[PMPM789]

Hello Guys

i have VM running with RDM/SCSI bus sharing physical . I need to take snapshot becasue of app team upgrades . i knew VMware snapshot doesn't support  VMs with RDM . VMs are configured for MS cluster . I can stop the cluster and and even VM shutdown . Is there any other possibility i can keep the VM safe and revert the application changes if we had to ?

Not if you're using pRDMs, no. They're just going to have to perform in-guest backups and manage the data carefully.
