A presentation at Veritas Vision 2004 mentioned the two tunables below, 
useful for tuning disk storage unit performance, similar to their bptm 
counterparts.

SIZE_DATA_BUFFERS_DISK
NUMBER_DATA_BUFFERS_DISK

However, doing a 'strings' on bpdm suggests that these tunables aren't 
present on HP-UX (have checked all the way to 5.0mp4).

NUMBER_DATA_BUFFERS_DISK seems to make an appearance in some versions of 
bpdm (Solaris 5.0MP3 certainly has it).

Anyone have any info they can contribute (eg what platforms/versions the 
tunables become present) ?

Thanks,

Joe.
