Summary of Amendments
for SY20-0882-3 as updated by SN25-0440 VM/370 Release 5 PLe 6
3340/3344 ALTERNATE TRACK SUPPORT Error Recovery Support
Software error recovery procedures in CP
now provide for switching to an
alternate track when an attempt to do I/O on a defective 3340 or 3344 track
results in a track condition Similar recovery procedures have also
been added to three stand-alone
utilities: the DASD Dump Restore (DDR)
Service Program; Directory Service
Program (DMKDIR); and the
Format/Allocate Service Program
(DMKFMT). This will enable these
programs to deal with 3340/3344 disks
having flagged tracks. The changes to
this publication reflect the changes
made to the three utility programs. xiv IBM VM/370 Service Routines Program Logic
