Ed,
All pages on your paging volume "go away" when you IPL anyway. The
easiest method might be:
1- Dedicate a whole new DASD to paging (paging and spool involve
seldom-ending channel programs for good performance, interrupting those
channel programs for other activity on the disk reduces system
performance). For example, let's use as the new volser: VMPG01 on rdev
200
2- Attach rdev 200 to your ID at 200
3- Running CPFMTXA: LABEL 200 as VMPG01,
FORMAT that 200 from cylinder zero to the end, and
ALLOCATE it for only paging (I still prefer to allocate PAGE 0 as PERM,
and 1-END as PAGE).
E.g. PERM 0 0
PAGE 1 END
3- Update your SYSTEM CONFIG to add the new DASD (maybe VMPG01 ?) as
CP_Owned.
4- Now that you have a new page volume ready, you can get CP ready to not
use the old page space at the next IPL.
CP reads the allocation bit map only when the volume comes online, so
you can change it ahead of time.
- Link R/W to your 430RES and 430W03 DASD (you can define full-pack
MDISKs to let you do that),
- run CPFMTXA to ALLOCATE the paging cylinders on both as PERM space
(do NOT format them!)
Only change the PAGE allocation to PERM.
E.g. 430RES as PERM 257 390
430W03 as PERM 1802 1901
5- Schedule a SHUTDOWN REIPL
After the IPL you *may* want to CPFMTXA the old page cylinders on 430RES
and 430W01 just to see if that causes I/O errors. If so, you know who to
contact. :-)

Re: HCPCLS174E using VSE SA util tape
Hello Alan,
I have been starting to see other messages that are
leading me
to actually believe that I have a bad disk.
Suddenly I can not logon MAINT without getting that
message.
(IPL 190). IPL CMS works ok.
Ready; T=0.01/0.02 11:30:43
q alloc page
EXTENT EXTENT TOTAL PAGES HIGH %
VOLID RDEV START END PAGES IN USE PAGE USED
------ ---- ------ ------ ------ ------ ------ ----
430RES 0792 257 390 24120 767 829 3%
430W03 075C 1802 1901 18000 240 250 1%
------ ------ ----
SUMMARY 42120 1007 2%
USABLE 42120 1007 2%
.
Could I
1) I can get a volume with only paging on it
2) tell System Config that the new volume is first, re-ipl,
3) do a q alloc page to ensure that the 430RES/430W03 page areas are not
being used.
4) either change the allocation to remove the page areas from
430RES/430W03,
or cpformat just those areas.
