AIX offers enhanced concurrency for shared LVM and VG resources. How does this fit in with TSAMP ?
Also refer to the DOC APAR IV44949
TSAMP does not support the use of enhanced concurrency under AIX as the fileset bos.clvm.enh is only supported when using HACMP and Power Mirror.
However, a solution (BCU, Smart Analytics, DB2 HADR...) that bundle TSAMP may choose to provide this support for their application/solution in which case enhanced concurrency could be used within a TSAMP managed environment. You would need to check the documentation for the solution you're using.
