If the System Load Fails or DSM/SCM Does Not Run
Correctly
If the System Load Fails or DSM/SCM Does Not Run Correctly
1. Perform a system load from the previously working SYS nn (renamed to SYS20).
2. Rename the current SYS nn (SYS00) and CSS nn (CSS00) back to the last built
SYS nn (SYS01) and CSS nn (CSS01), respectively. For example:
> FUP RENAME $SYSTEM.SYS00.*, $SYSTEM.SYS01.*
> FUP RENAME $SYSTEM.CSS00.*, $SYSTEM.CSS01.*
3. Rename the previous SYS nn to the name it had at the completion of the Apply. For
example:
> FUP
> RENAME $SYSTEM.SYS20.*, $SYSTEM.SYS00.*
> RENAME $SYSTEM.CSS20.*, $SYSTEM.CSS00.*
4. Run ZPHIRNM to reverse the ZPHIRNM performed before the renaming of the
SYS nn .. For example:
> RUN ZPHIRNM $ volume .SYS00, FROM $ volume .SYS01
5. Perform a system load from the newly renamed working SYS nn (now renamed to
SYS00).
6. Start DSM/SCM.
7. Run ZPHITI to perform the Target Interface backout step (Tasks 2 through 4 of
Backing Out If DSM/SCM Is Running on page 4-1) to back out to SYS00.
