VMAX3: "Create SRDF Group" using Unisphere for VMAX does not map all selected SRDF-Director-Ports to the new SRDF-group

"Create SRDF Group" using Unisphere for VMAX.

• SRDF Groups are found with less paths than desired.
• Unisphere for VMAX  is used to create a new SRDF-Group. Both on the local and remote side Directors and Ports are selected. Although the operation completes successfully, not all previously selected Director Ports are included in the new SRDF-Group.

More than one Port of an SRDF-Slice (Director) need to be included in a new SRDF Group. If Unisphere for VMAX is used, only one port on each SRDF-Slice (Director) is included in the new SRDF-group and not all selected ports.

In Unisphere for VMAX select "Data Protection", "Replication Groups and Pools" and then "SRDF Groups". Select the relevant SRDF Group and use "Edit" to correct. See "Correction of the above scenario" in the notes tab for details.

Example of a failing scenario:

1.  In Unisphere for VMAX "Data Protection" and common task "Create SRDF Group" is selected.

2.  The mask is filled out and all available Director-Ports (In this example 2F:24, 2F:25, 3F:24, 3F:25) are selected. 3.  After pressing "OK", the operation ends successfully. 4.  To check the result go to "Data Protection" and "Replication Groups and Pools"

5.  Select "SRDF Groups" 6.  Select the newly created SRDF Group, in our example "TEST-RDF8" and click "View Details". 7.  It is now visible that the new SRDF Group only contains Director-Ports 2F:25 & 3F:25 and not 2F:24 & 3F:24 8.  The same can be observed with Solution Enabler:

Correction of the above scenario:

A) Navigate again to "Data Protection > Replication Groups and Pools > SRDF Groups", select the newly created SRDF-Group and click "Edit".
B) Select again all Director Ports on the local and remote system. (In this example 2F:24, 2F:25, 3F:24, 3F:25) Press "OK". C) Message Box "Success modifying SRDF Group" appears D) Navigate again to "Data Protection > Replication Groups and Pools > SRDF Groups", select the newly created SRDF-Group and click "View Details". The newly created SRDF Group now contains all desired Director Ports: The successful correction can also be confirmed with Solution Enabler:

Notes:

• This issue occurs regardless of the selected Communication Protocol "FC" or GIGE".
• Solution Enabler is not affected, the following "symrdf" command immediately leads to the desired result::
