Notes

Note

  • The maximum limit for the IPs that can be associated with an SDS is 8.

  • There needs to be at least 1 IP for SDS communication and 1 for SDC communication.

  • If only 1 IP exists, it must be with role ‘all’; else 1 IP can be with role ‘all’and other IPs with role ‘sdcOnly’; or 1 IP must be with role ‘sdsOnly’ and others with role ‘sdcOnly’.

  • There can be 1 or more IPs with role ‘sdcOnly’.

  • There must be only 1 IP with SDS role (either with role ‘all’ or ‘sdsOnly’).

  • SDS can be created with RF cache disabled, but, be aware that the RF cache is not always updated. In this case, the user should re-try the operation.

  • The check_mode is supported.

  • The modules present in the collection named as ‘dellemc.powerflex’ are built to support the Dell PowerFlex storage platform.
