Unless you have some compelling reason to stay with -9's, consider going to the -27's. With PAV's there are little or no performance issues. Frees up UCB's for added capacity.
However, IBM should make you some killer price offers on new hardware this time of year. It just might be cheaper to replace the old box. Consider that new boxes come with a four year warrantee. How much do you pay per year for maintenance now? HTH and good luck. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Len Rugen Sent: Tuesday, December 20, 2005 7:42 PM To: [email protected] Subject: Reconfigure Shark 3390-3's to -9's question When we moved from a MP3000 with internal disk to a Shark (old, used, F20? I think, fairly small drives anyway) I needed a lot of 3390-3 volumes. Our shark is half full, I think that's 4 drawers, I configured one with 62 3390-3's and 4 1000 cyl "mini" volumes for things like MIM and JES CKPT. I configured the other 3 drawers as 3390-9's or slightly larger, whatever worked out. BUT, with base and alt. addresses, I used all the addresses, at least in the range for the 3390-3's. (that was overkill, but it's fast) As time passes, I've eliminated a lot of the 3390-3 requirements. What is required to reconfigure some or all of these to 3390-9's? Do I have to do the entire drawer or can I do parts / areas at a time? It looks like each drawer has 2 LCU's in the IODF, for a total of 8. And it's still ESCON, if that matters and connected to a z800 at z/OS 1.4 Thanks ---------------------------------------------------------------------- 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
