Description
Load System. Pressing'the carriage return key (CR) when deadstart
options are displayed causes system deadstart processing to continue.
Additional options cannot be selected after this entry. This has special
significance with respect to the K, W, X, 0, and 1 options. That is,
if values specified for word 13 or word 14 on the deadstart panel are
to be modified, the changes must be completed before entering this
option.
If
any error status bits are set in a status
I
control register (CDC
CYBER 170 Series only), processing proceeds as if the R option
had been entered. The contents of the
SIc
registers are displayed
and operator action is required (refer to R Option).
Operator intervention after the CR option is entered is the same as
that described in the procedure for Automatic System Deadstart.
Continue with one of the following steps in that procedure.
a. If bits 0 through 5 of word 14 are set to zero via the deadstart
panel switches or by using the W option (no system device
specified), continue with step 3 in the procedure for Auto-
matic System Deadstart (disregard comment in first sentence
concerning the deadstart switch). '
b. If one or more system devices are specified in bits 0 through 5
of word 14, continue with step 6 in the procedure for Auto-
matic. System Deadstart.
Ignore non-fatal errors in status
I
c'ontrol register (CDC CrBER 170
Series only) and memory confidence testing. If a fatal error is
encountered during memory confidence testing, the deadstart
sequence unconditionally terminates.
Set CMRDECK Number. This option displays the current CMRDECK
number, specified by bits 3 through 8 of word 13 on the deadstart panel,
and allows selection of an alternate CMRDECK. If a level 1 or level 2
recovery deadstart is to be performed, the CMHDECK selected during
the most recent level 0 deadstart must be used. The CMRDECK is
ignored and 'the current equipment configuration is retained if a level 3
recovery deadstart is performed.
The display produced temporarily replaces the options display and
consists of the following one line message that appears in the center
of the screen.
SET CMRDECK 00
"(current CMRDECK number)
The operator then enters the number of the alternate CMRDECK to be
used. The number entered replaces the number currently displayed.
Pressing the carriage return key (Cn) returns the options display and
additional options can then be selected.
For additional information concerning CMRDECK selection, refer to
Selecting the CMRDECK earlier in this section.
Deadstart Another Tape. This option allows an alternate deadstart
tape to be used. The alternate deadstart tape unit must be connected
to the same channel as the current deadstart tape unit.
