symld command not in version 9.0.0

Have installed Solutions Enabler 9.0.0 on Redhat:

[root@host ~]# rpm -qa | grep symcli
symcli-data-9.0.0.2504-18.3.x86_64
symcli-symcli-9.0.0.2504-18.3.x86_64
symcli-cert-9.0.0.2504-18.3.x86_64
symcli-base-9.0.0.2504-18.3.x86_64
symcli-symrecover-9.0.0.2504-18.3.x86_64
symcli-thincore-9.0.0.2504-18.3.x86_64

On previous versions I would have added a new LUN to an existing SRDF group with:

symld -sid  500 -g add dev

However symld is no longer included in version 9.0.0

With symld gone, what is the correct process to add a LUN?

Many thanks!
