CONFIGURATION

OS / ENVIRONMENT

VMware hypervisor

SUMMARY

Attach disk is failing with error "The specified VM already has the maximum number of data disks (13) attached. Please specify another VM." even thought the hypervisor version supports more than 13 disks, which is specified in the max_data_volumes_limit of hypervisor_capabilites table for that hypervisor version. The data volumes limit is being picked from "default" version of hypervisor instead of the actual version.

STEPS TO REPRODUCE

1. Create a VM (in VMware hypervisor)
2. Attach upto 14 data disks to the VM

EXPECTED RESULTS

The data disks limit from the actual hypervisor version has to be considered while attaching the disks

ACTUAL RESULTS

The data disks limit from the "default" hypervisor version is picked up while attaching the disks
