CRTBTB fails if INIBTB fails. This can happen if DSKASA fails to

to build BS:, gets a failure return from DIRINI, which is trying to
initialize the root-directory. DIRINI fails if its call to MAPDIR
fails, or if the SETZM which first touches the directory fails. MAPDIR
fails if either the structure or directory number is out of range,

BUG.(CHK,FILHOM,FILINI,HARD,<FILRFS - Unable to rewrite home blocks in WRTBTB>,,<
Cause: FILRFS is attempting to refresh BS:. WRTBTB is called to write the bit
table. This BUGCHK indicates that WRTBTB failed because the home blocks
are bad.
Action: The home blocks must be repaired. Select a different disk pack to
build the system on. If the trouble persists, have Field Service check
the system. If the problem can be reproduced on healthy hardware, send
in an SPR along with a dump and instructions on reproducing the
problem.

several reasons. For example, ASGPAG can fail or the count of front
end pages in the home blocks can be negative.
Action: Select a different disk pack to build the system on. If the trouble

BUG.(HLT,FILMAP,FILINI,HARD,<FILIN2 - Could not map in ROOT-DIRECTORY>,,<
Cause: During standard system startup, SETDIR failed to map in the root
directory for consistency checking. SETDIR fails if CNVSTR fails
to convert structure number data or if MAPDIR fails to map in the
directory, or if DR0CHK finds a directory header inconsistency.
Action: There appears to be a hardware problem with the BS: file structure. If
the trouble persists, have Field Service check the system. If the
problem can be reproduced on healthy hardware, send in an SPR along
with a dump and instructions on reproducing the problem.
>)
CALL BLKSCN ;MAKE SURE IT IS VALID
BUG.(HLT,BADROT,FILINI,HARD,<FILIN2 - ROOT-DIRECTORY is invalid>,,<
Cause: When the system was coming up, BLKSCN was called to check the
consistency of the root directory. This error means that BLKSCN found
that the root directory had an unrecognizable type, the last block did
not have the expected length, or some block had an incorrect format.
Action: Use EDDT to break after BLKSCN and examine the error code in AC1. This
code indicates what is wrong with the root directory. If
other BUGCHKs or BUGINFs occur with this BUGHLT, they also can provide
helpful information.
If the system can be brought up using another structure as PS:, the bad
structure can sometimes be fixed with various tools such as FILDDT. If
this restoration fails, the pack can be started afresh and pertinent
DUMPER backup tapes can be used to restore the structure.
If the trouble persists, have Field Service check the system. If the
problem can be reproduced on healthy hardware, send in an SPR along
with a dump and instructions on reproducing the problem.

BUG.(CHK,BADIDX,FILINI,HARD,<IDXINI - Partially unsuccessful index table rebuild>,,<
Cause: IDXINI failed to create the index-table file during file structure
creation. Some of the directories may have been entered into the file
before this failure occurred.
Action: There appears to be a hardware problem on this system. If the trouble
persists, have Field Service check the system. If the problem can be
reproduced on healthy hardware, send in an SPR along with a dump and
instructions on reproducing the problem.
