HELP INFORMATION
Use this screen to define a
disk (minidisk) for the above user.
1 The VIRTUAL DISK ADDRESS is the
address by which the minidisk is
known to the virtual machine. Enter
a 'blank address to delete minidisk.
2 The DRIVE
10
is a letter identifying
the drive the minidisk resides on.
3 The NUMBER OF BLOCKS represents how
many 512 byte blocks are to be
allocated to the minidisk.
5-6 The SHARE PASSWORDS allow
other users knowing the password
to access this user's minidisk
in READ ONLY or READ/WRITE mode.
Figure 3-3. Update Minidisk for User Menu
Note that, for this screen, the scroll keys will now scroll
through the minidisk list, not the user list.
The "Virtual Disk Address" is the address of that simulated
disk as seen by this virtual machine. It is in the form of
CUU (channel and unit address) as are all input/output
device addresses in System/370. This field will be "101"
since we selected the SAMPLE 101 disk. To delete a
minidisk simply blank out the "Virtual Disk Address" area
and press ENTER.
The "Drive ID" is the drive letter of the drive where the
actual minidisk data will be simulated and stored.
(Remember that the drive letter B can be used only if you
have two diskette drives.)
The "Size of Minidisk" represents the size of the simulated
disk. It is measured in the number of 512-byte blocks
allocated to the disk. The SAMPLE 101 disk consists of
1024 physical blocks on the real drive C. That gives the
SAMPLE 101 disk a storage capacity of 1024 X 512
=
512 K bytes or 1/2 megabyte. The size of a minidisk can
range from 1 to 20480 blocks. For the minimum size
