I agree about 'caused by concurrent R/W', and the steps to fix...
but on the DMSDKD1307T, I've seen a case...

Probably not related... a long time ago, yes...

Most readers missed the real issue: DMSDKD1307T error This means the
minidisk is corrupted and must be repaired. In my long VM history, all
corrupted minidisks were caused by concurrenbt R/W access, not by some CMS
bug that appears when a disk gets100% full.
Using DDR can't help at all: it will copy the error over to the target
minidisk.
One must save the good files one by one and then reformat the corrupted
minidisk. Using a Tdisk as temporaly place isn't very good: if VM would
bounce (or a power outage, or ...) your Tdisk gets lost. Better thus is
using some other permanent minidisk or an SFS directory, or use SENDFILE
to store them in the spool.
COPYFILE * * sourcefm = = targetfm (OLDDATE
will break when it reaches a broken file. Better is thus using FILELIST
and EXECUTE
- FILELIST * * sourcefm
- EXECUTE * COPYFILE / = = targetfm (OLDDATE
or EXECUTE * SENDFILE / TO * (NOLOG
Then when CMS abends due to the broken file, re-IPL CMS,
- find the last file that was copied fine
- restart FILELIST and go to the last file that copied OK
e.g. with this locate command: /lastgoodFn lastgoodFt/
- skip this good file and the bad one by entering +2
- start copying: EXECUTE * COPYFILE .... or EXECUTE * SENDFILE ...
If you have many broken files, it is a long process...
If you use a second minidisk or SFS directory, you could get my COMPARE
package from VM's download lib at
http://www.vm.ibm.com/download/packages/
it contains a COMPMDSK XEDIT macro to compare the contents of two
minidisks/directories:
- FILELIST * * sourcefm
- COMPMDSK targetfm
Then it is easy to find which files are missing/different..
