• ENTER OLD FAMILY NAME
This message appears only if
more than one family of
permanent file· devices are
currently active in the system.
Enter the following response.
K. FM=family name.
• ENTER OLD DEVICE NUMBER
This message appears if the
device to be initialized is a
'permanent file family device.
Enter the following response.
K. DN=device number.
• ENTER OLD PACK NAME
This message appears only if
the device to be initialized is an
auxiliary device. Enter the
following response.
K. PN=pack name.
t
• ENTER OLD USER NUMBER
This message appears only if
the auxiliary device to be
initialized is a private auxiliary
device (associated with a
specific user number). Enter
the following response.
K. UN=user number.
t
If it is discovered that the wrong device
was specified in the INITIALIZE
command, initialize status for that
device can be cleared by entering
K. CLEAR.
t
The device to be processed by the clear
entry must be a valid device. That is,
the device cannot have a device number
that conflicts with another device in its
family or a pack name that duplicates
one already in the system. Its mask bits
must meet standard requirements.
The leftmost device in the list of devices
to be initialized is cleared. One of the
preceding messages will then be
displayed for the next device to be
initialized (if any) providing the label on
that device is good.
5. When the following message appears on
the K display, enter the parameters
which specify the new characteristics to
be associated with the device when it is
initialized (refer to tables 3-1 and 3-2).
ENTER PARAMETERS
The new parameters can be entered one
at a time or as a string. For example:
or
K.optionl =value1,""
optionn=value n •
K.optionl =value l'
K.option2 =value 2
K.optionn=value n •
If flaw entries are to be specified (refer
to table 3-2), they must be entered singly
as illustrated in the last example. If the
label on the device being initialized was
good, all current flaws on that device are
normally recovered. However, if the
label was not recognized or was bad, the
flaw entries cannot be recovered and
must be entered (if necessary) using this
mechanism. A maximum of 20 octal
flaw entries are permitted.
In
addition
to RTK, TTK, and STK entries, the flaw
information recorded in the utility sector
on an 881 or 883 disk pack is read during
initialization of 844 equipment and the
appropriate areas automatically reserved
by the system.
If the NP option is specified (NP=O), the
device is to be initialized as a
multispindle device. In this case, the
number of packs specified by NP indicate
the number of spindles to be linked. This
is the next n number of devices waiting
to be initialized. Each device must be
defined as removable and mounted on
consecutive physical ~it numbers. To
determine if a device is defined as
removable, examine the mass storage
status (E,M.) display (refer to section 4).
If the units are configured correctly, the
labels on each unit are checked. If any
label is not recognized or is bad, that
. unit is free for initialization and
chaining. However, if the label is good,
the message
ENTER IDENTITY OF EQxx
appears in the K display (xx is the EST
ordinal of the device). One of the
following responses is required.
• K. FM = family name, DN
device number.
• K. DN = device number.
• K. PN = pack name.
• K. PN = pack name, UN = user
number.
This is a precautionary measure to
ensure that the devices specified are the
correct devices to be chained.
t
All parameter entries must be prefixed by K period (K.). However, when pressing CR after the first parameter entry,
everything but the K. is erased. This allows another parameter to ·be entered without first having to enter K. If' it
becomes necessary to enter a DSD command during parameter entry, simply press BKSP to erase the K., enter the
command, and then continue parameter entry by typingK. and the parameter.
