Couple of points here. Define PAVs as DYNAMIC and Not STATIC; the DASD Subsystem will put the water where the fire is. I have seen 47 PAVs (I have 48 defined to each LCU) volumes to one logical device.
Also if you are ESCON consider going to FICON; a considerable difference in performance. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of O'Brien, David W.

I have some 24 Mod3s in reserve now. There are also other volumes that could be recovered from the Zos folks. At the time this methodology was introduced, we might have been tighter on DASD. I was just wondering if there was any reason not to be doing this.

How is your paging subsystem? Is there a lot of paging going on your Systems? My system COMMON and PLPA are on same volume All LOCALS have their own volume. No mixing of different LPAR Locals on the same volume. I max out my LOCALS as big as I can make them. We are going to MOD9s so they are getting bigger.

(We don't page much.) ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
