# server.
|
||||
#
|
||||
# [*vxflexos_storage_pools*]
|
||||
# (String) (required) Storage Pools. Comma separated list of storage pools used to provide volumes.
|

|
||||
# If not set, the storage_availability_zone option value
|
||||
# is used as the default for all backends.

# volume creation will fail for volumes not sized properly
|
||||
# Defaults to $::os_service_default
|
||||
#
|
||||
# [*vxflexos_server_api_version*]
