Hi all, 10 days ago we activated z/VM 5.4 in production. All worked really well.
But yesterday when I logged on MAINT I noticed that CMS didn't IPL. It now seems that IPL 190 no longer works (in any VM-userid). After entering the IPL 190 command (or just logging on to MAINT) nothing happens. From that point on other users that issue IPL 190 or IPL CMS will hang as well. A LINK to a minidisk on the same volume (540RES) will hang as well. It seems that the whole volume is being locked. We can solve the hang by issuing #CP IPL CMS in the machine where the IPL 190 was issued (IPL CMS still works fine). Other users can then proceed as well. When I do an IPL 190 in user MAINT, Performance Toolkit shows this for USER MAINT: ... Device activity and status: 0009 3215 .0 000C 254R CL *, EOF NOH NCNT 000D 254P CL A, CO 01, NOH NCNT 000E 3211 CL A, CO 01, NOH NCNT 0112 3390 .0 B001,RR, 65Cyl,--->0 0123 3390 .0 B03C,WR,3339Cyl,--->0 0124 3390 .0 B03D,WR,3339Cyl,--->0 0125 3390 .0 B03E,WR,3339Cyl,--->0 0190 3390 .0 B03C,WR, 107Cyl,BUSY 0191 3390 .0 B03C,WR, 175Cyl,--->0 ... Please note that 190 is marked BUSY. It stays that way until I issue #CP IPL CMS in user MAINT. I also tried an IPL 490 in user MAINT and that hangs as well. I copied MAINT 190 using DDR to another volume as minidisk A190 and issued IPL A190 and that hangs as well. I then made this minidisk available to another VM-system, IPLed it, and that works fine. Any ideas what's going on? Thanks, Geert. _____________________________ Geert Dieltiens Systeembeheerder Informatica J.
