Maximum size of swap partition in cluster 5.1b-3

Hello all,

Apparently, the default maximum swap partition size in the creation of a 
cluster member (5.1b-3) is 8gb.  Last year, I found the file which could be 
edited to raise that limit.  I thought it was a parameter in 
/etc/sysconfigtab, but now I can't find the reference.

How can I raise the maximum swap partition size for a cluster member in 5.1b-3?

Thanks.

John
