Some performance improvements in that process are included. Also, a (extra cost?) 'hyper PAV' that uses a 'ucb' from a pool only for the duration of the I/O. Talk about instant gratification :-)

The larger the volume, the greater the impact of a failure. After time, I wonder what fragmentation would look like. -----Original Message----- From: Ron Hawkins [mailto:snip] Sent: Thursday, August 14, 2008 10:09 AM To: IBM-MAIN@BAMA.UA.EDU Subject: Re: Here we go again (was z/OS Hot Topics 19) John, Not really. A disk failure - two disk failures actually - on an Array Group of 3390-3 can affect over 300 volumes. I would much rather manage restoring 4-10 large volumes than 300+ small ones.
