Thanks!

The problem one our customers is seeing is a disc load imbalance.
He's got two discs in MPEXL_SYSTEM_VOLUME_SET, (and 20+ drives in
various user volume sets), but he's pausing for disc a lot, and the
io queue length on LDEV 2 gets pretty high.  Current theory: his
applications do a lot of spoolfile writing, and it's all happening on
LDEV 2 since MPE is studiously avoiding LDEV 1.
