B.1.2 DEADSTART
|
|
|
|
The following procedure describes how to deadstart the lOS from either
|
|
tape or disk. The deadstart tape and disk contain the following files:
|
|
|
|
Tape Disk Description
|
|
------ --------- -------------------------------
|
|
FILE 0 TAPELOAD Tape deadstart program
|
|
FILE 1 DISKLOAD Disk deadstart program
|
|
FILE 2 DMP I/O Processor dump program
|
|
FILE 3 KERNEL The IOS Kernel
|
|
FILE 4 KERNEL.OV IOS overlays
|
|
FILE 5 COS COS
|
|
FILE 6 PARAM Parameter file
|
|
FILE 7 CLEARIO Clear IDS program
|
|
FILE 8 DSDIAG IOS deadstart diagnostic control program
|
|
FILE 9 DSDIAG.OV IOS deadstart diagnostic overlays
|
|
|
|
Step Procedure
|
|
---- ------------------------------------------------------------
|
|
1a. Mount the deadstart tape on the Peripheral Expander tape unit.
|
|
or
|
|
lb. Mount the deadstart disk in the Peripheral Expander drive unit.
|
|
2. Set lOS maintenance panel toggle switches as follows:
|
|
|
|
Switch Setting
|
|
Loading From Octal Binary
|
|
--------------------------- ------- --------
|
|
Tape 22 010 010
|
|
AMPEX disk unit 60 110 000
|
|
CDC disk unit 27 010 111
|
|
|
|
3. Depress IOP-O MC (or MASTER CLEAR on CRAY-1/A) and DEADSTART
|
|
buttons on the Power Distribution Unit or lOS chassis maintenance
|
|
panel (depending on your site).
|
|
|
|
4. Respond to the prompt at the MIOP Kernel console as follows. (If
|
|
the FILE @MTO prompt is not displayed, verify that a tape is
|
|
mounted on the Peripheral Expander tape unit.)
|
|
|
|
Prompt Response
|
|
----------- ------------------------------------------
|
|
FILE @MTO: Enter 3 and press RETURN (loads Kernel and
|
|
performs initialization)
|
|
|
|
FILE @DKO: Enter either the directory name (dir/) to
|
|
display a menu of all files in requested
|
|
directory or enter the
|
|
Kernel filename (dir/Kernel) to load the
|
|
Kernel and perform initialization.
|
|
|
|
Press RETURN.
|
|
|
|
============================================================
|
|
NOTE
|
|
When starting from disk, the Kernel expects the Kernel
|
|
overlays to have the same Kernel name and appended with
|
|
a ".OV" (for example; a Kernel with file name lOS must
|
|
have the overlays with filename IOS.OV).
|
|
============================================================
|
|
|
|
The Kernel goes through its initialization sequence and displays
|
|
the following message on the Kernel console of all lOPs:
|
|
|
|
IOP-n KERNEL, VERSION x.xx SNsn, site. mm/dd/yy hh:mm:ss
|
|
|
|
n Number designating the lOP where the console is
|
|
attached
|
|
x.xx Software version number
|
|
sn Mainframe serial number
|
|
site Installation location
|
|
mm/dd/yy Kernel assembly date
|
|
hh:mm:ss Kernel assembly time
|
|
|
|
The following message can appear on the BIOP or DIOP console only:
|
|
|
|
DISK NOT READY CH nn
|
|
|
|
The message indicates that the configured system disk has not
|
|
responded to attempts to select it. The disk might be disabled at
|
|
the lOS Power Distribution Unit cabinet, at the lOS deadstart
|
|
panel, or at the disk unit itself (maintenance mode). This
|
|
message may not indicate a problem since the operating system
|
|
being loaded in the mainframe controls which configured devices
|
|
must be present for successful operation.
|
|
|
|
5. If your IOS does not have a Peripheral Expander clock, two prompts
|
|
are issued at the MIOP Kernel console for the current date" and
|
|
time.
|
|
|
|
============================================================
|
|
NOTE
|
|
If your lOS is equipped with a Peripheral Expander
|
|
clock, you are not asked to enter date and time. See
|
|
SETIME command (section 2) to set or reset the
|
|
Peripheral Expander clock.
|
|
|
|
Proceed to step 6.
|
|
============================================================
|
|
|
|
After the "ENTER DATE:" prompt, enter the date in the following
|
|
format:
|
|
|
|
mm/dd/yy
|
|
|
|
Once the date has been accepted, the MIOP Kernel console displays
|
|
the "ENTER TIME:" prompt. Enter the time in the following format:
|
|
|
|
hh:mm:ss
|
|
|
|
6. Proceed to the Cray Mainframe Deadstart procedure (subsection B.2).
