Log minidisks: NOMDC (it is write only, except during SFS startup) Control minidisks: NOMDC (well cashed by SFS itself) Storage groups 2-n: minidisks: MDC (unless you know that some stg group is mostly written to only)
For the catalog minidisks (storage group 1), I asked years ago if MINIOPT RECORDMDC wouldn't be better than the default fulltrack MDC because I suppose that storage group 1 is not sequentially read, but with direct access.
