- ATTACH
The following ATTACH commands are required to execute this diagnostic:
ATTACH DW730 HUB DW0 5
ATTACH RB730 DW0 DQA 776606 50 5
ATT R80 DQA DQAx
where x is an arbitrary unit number.
- HELP
The function of this diagnostic is to format the RM80 HDA assembly.
It is a level 2 diagnostic, which must run under the VAX Diagnostic
Supervisor, either standalone or under VAX/VMS.
- SECTIONS
There are 7 sections, each of which can be selected for execution
via a section switch in the start command line. By default, none of
the sections are executed, but a list of the sections names and
functions are displayed.
- DISPLAY
This section is used to display the contents of the skip sector
file and the bad sector file. It will also check the validity of
each file.
- HDAINI
This section formats either the skip sector file track or the bad
sector file track, as desired. Then a zero entry bad or skip sector
file is written and verified.
*** THIS SECTION SHOULD ONLY BE RUN IF THE DISK SUBSYSTEM IS ***
*** KNOWN GOOD, AND THE SECTOR FILE IS KNOWN TO BE CORRUPTED ***
- FORMAT
This section reads and validates both the sector files. The disk HDA is
then formatted one track at a time. Bad sectors are flagged and added
to corresponding sector files.
- VERIFY
This section writes/reads and validates both the sector files. The disk
HDA is then analyzed, and bad sectors are flagged and added to the
corresponding sector files. ***WARNING:***this section will write/read
the complete HDA.
- READALL
This section reads every sector on a HDA and prints any data errors
found in a head map error report.
- UPDATE
This section prompts the user for the address of a bad block, then
rewrites the bad or skip sector file.
- REBUILD
This sections rebuilds a bad or skip sector file. The track where the
selected file is located is formatted, then a zero entry file is written
to that track. From there, the same procedure as UPDATE is executed.
- HELP
This is the default section. Section names are identified along with
their function.
- EVENT FLAGS
Event Flags 1,2,18,19,20,21,22,and 23 are implemented,
- EV1
Event Flag 1 allows QIO error retries. Under normal use, this flag
should never be set.
- EV2
Event Flag 2 allows system error logging.
- EV18
When Event Flag 18 is set and section format is started, only HDA
reconstruction takes place with no verification.
- EV19
When Event Flag 19 is set only the FE cylinders are formatted. No
writes are ever done to the customer area of the HDA.
- EV20
Event Flag 20 is effective in standalone mode only. This flag, when
set, causes single track transfers in the surface analysis test.
- EV21
Event Flag 21 causes any error messages to be printed in brief format.
- EV22
Event Flag 22 causes the starting disk address to be printed once every
100 cylinders. This flag supersedes flag 23.
- EV23
Event Flag 23 causes the starting disk address to be printed for each
step in a section.
- QUICK
The Quick Flag is used during the verify section only. Under
normal conditions every track is reread 5 times. With Quick set,
every track is read just once.
