TABLE 3-1. DEVICE DEFINITION OPTIONS (Contd)
Option
DM=
SM=
NC=
EQ=
NP=
DN=
Description
Three-digit (octal) device mask
(0
to 377).
This option is required whenever a
permanent file master device is being
initialized. It defines which users will have
this device as their master device. This
option cannot be entered if TY=X.
Three~digit
(octal) secondary device mask (0
to 377) used to control the residence of
direct access files. This option is only
meaningful on family devices.
Octal number. of. catalog tracks (power of
two). This option is used only if the number
of catalog tracks specified as system default
for the device type is not satisfactory. The
maximum value is 2008.
EST ordinal of device to be initialized. For
mul tispindle devices, this must be the first
of NP consecutive removable units.
Number of physical units to be included in a
multispindle device. The default value is 1.
Each unit to be included in the multispindle
chain must currently be defined as
removable in the mass storage status (E,M.)
display (refer to section 4).
Two-digit (octal) logical device number (1 to
77) that uniquely identifies the device in its
permanent file family. This option is not
entered if TY=X.
TY=F Initialized device may contain direct and
indirect access permanent files. However,
if DM=O, only direct access files may reside
on the device. If SM=O and DM=O, the
device may only contain special system
permanent files. Indirect access files can
. only reside on a master device (that is,
DM:#O).
TY=X Initialized device is an auxiliary device.
This is a mass storage device that is not part
of a permanent file family. An auxiliary
device is a supplementary permanent file
storage device that may be privately owned
(UN option specified) or may be shared by
many users (UN not specified). Auxiliary
devices may contain direct or indirect
access permanent files.
t Device definition may be changed only if AL
initialization is specified.

TABLE 3-2. TRACK FLAWING OPTIONSt
Option
RTK
TTK
Description
Converts input physical address to a logical
address and sets TRT to indicate that track
is a reserved, flawed track.
Input is the same as RTK option but track
reservation is toggled. That is, if the track
was previously not reserved, this option
produces the sam e resul ts as the R TK
option. If the track was previously reserved
as a flawed track, that reservation is
removed.
STK Performs the same function as RTK except
that input address is a logical address (no
conversion required).
t Flawing of 881 and 883 disk packs is automatic; only
flaws additional to current information should be
entered.
3.
Enter the INITIALIZE command for
each additional device to be
ini tialized. This can also be done
before activating the K display. In
either case, only the first device
specified will initially be listed (by
EST ordinal) in the K display. Thus, to
update the K display to show
additional devices, enter the following
command.
K.RERUN.
If more than one devic.e is listed, they
are initialized one at a time as they
appear in the list from left to right.
Multispindle devices (more than one
EST ordinal) are considered one device.
4. The system has already checked the
. label on each mass storage device. If
the label was found to be good, it is
necessary to enter parameters
(requested in messages that appear in
the K display) to identify the device.
This is to ensure that the device
selected is indeed the correct device
to be initialized. The messages appear
automatically and are displayed until
the correct parameter is entered. If
an incorrect parameter is entered, it is
ignored. Refer to table 3-1 for a
description of each parameter.
Examine the mass storage status
(E,M.) and/or mass storage
configuration (E,C.) display to
determine the current parameter
values.
The following possible messages may
be displayed and the appropriate
response should be entered. If none of
these appears, the device label was not
recognized or was found to be bad. In
this event, proceed to step 5.
