Hi Ugin, there is no way to work around the restrictions but the restriction vary across the different models. Typically we should be looking at max SRDF groups/array. Have a look at the VMAX3 product guide, through solve desktop. TABLE 11 SRDF features by hardware platform gives a good picture of what you can do. a. If both arrays are running HYPERMAX OS, up to 250 RDF groups can be defined across all of the ports on a specific RDF director, or up to 250 RDF groups can be defined on 1 port on a specific RDF director. b. A port on the array running HYPERMAX OS connected to an array running Enginuity 5876 supports a maximum of 64 RDF groups. The director on the HYPERMAX OS side associated with that port supports a maximum of 186 (250 – 64) RDF groups. c. If hardware compression is enabled, the maximum number of ports per director is 12
If this is 5876 code, then JimmyNyhan's response above is still accurate with regards to VMAX1/VMAX2 code. You can see these numbers in the SRDF CLI Product Guide (SE 7.6 set for this reference). You are not limited to 32 RDF groups with the code you referenced above, it would be 250 RDF total or 64 per RDF director. Anything more than this would require you to contact your EMC account team for them to investigate going over these limits.

As you said only 32 groups per SRDF director supported in 5772 and 5773 Enginuity.
I believe i read some restriction around this long back.

I think he is referring to DMX models, which has 32 RDF group per director, thats why i mentioned the code level 5772 & 5773

It's not DMX. It's VMAX 5876 with lates updates.
