i'm by no means an s390 expert, so i might be missing something obvious. we've had an install running for a couple of years. recently the rootfs had some important libs deleted, so it's now unbootable. i don't want to format and lose data on it. so i'm trying to boot a kernel+initrd that i have locally so i can recover things.
from the docs [1], i need to first copy those files into a DASD before
i can IPL or punch+IPL them. our VMs have the following DASD's:
00: DASD 0150 3390 MRC79A R/W 3336 CYL ON DASD C79A SUBCHANNEL = 0006
dasda1 /boot
dasda2 /usr
00: DASD 0151 3390 MRC79A R/W 3338 CYL ON DASD C79A SUBCHANNEL = 0007
dasdb1 /
00: DASD 0160 9336 (VDSK) R/W 200000 BLK ON DASD VDSK SUBCHANNEL = 000F
dasdc1 swap
00: DASD 0190 3390 MRCA02 R/O 214 CYL ON DASD CA02 SUBCHANNEL = 000C
00: DASD 0191 3390 MRC790 R/W 2 CYL ON DASD C790 SUBCHANNEL = 0008
dasdd
00: DASD 019E 3390 MRCA02 R/O 500 CYL ON DASD CA02 SUBCHANNEL = 000D
00: DASD 0200 3390 MRC79E R/W 32759 CYL ON DASD C79E SUBCHANNEL = 0005
dasde1 /mnt/space
00: DASD 0592 3390 MRCA09 R/O 240 CYL ON DASD CA09 SUBCHANNEL = 000E
00: DASD 8888 3390 MRCA05 R/O 30 CYL ON DASD CA05 SUBCHANNEL = 0004
the only DASD i can see that i can write to from CP/CMS is 191, but it
is much too small to hold the kernel+initrd. these files are only a
few MB, but can't even fit 1 MB into 191.
i don't want to format 150/151/200 since they have our data. i don't
think i can reconfigure 160 temporarily. all the rest are read-only.
any suggestions ? if there was a way i could ftp (or send file from
x3270) directly into the spool, that seems ideal as i could then ipl
straight out of it.
