3-34 Preparing for Cross-OS File Exchange Operations
Hitachi USP V Cross-OS File Exchange User’s Guide
-b blocklen: Specify the block length (decimal) of the dataset being
allocated.
When record format = F, block length = record length.
When record format = FB, block length = record length × N (N =
integer).
When record format = V/VB, block length = record length + 4 or
more.
This parameter is required. If not specified, the following default values are
used:
When record format = F/FB, default block length = record length.
When record format = V/VB, default block length = record length + 4.
-c cylinders: Specify the size of the dataset being allocated in number of
cylinders (decimal). This parameter is required. If not specified, the default
value of 100 is used.
3. If the ALC allocate operation could not be started due to an error condition,
the Allocate check error message is displayed. If the ALC allocate operation
did not complete successfully, an error message is displayed. Remove the
error condition, and retry the operation. See section C.2 in Appendix C for
further information on errors in UNIX.
Windows 2000/2003/Windows NT systems: To allocate an intermediate FXoto
dataset using the ALC utility:
1. Log in to the system as administrator.
2. Double-click on the Allocate icon to start the ALC utility and open the
Allocation panel.
3. The ALC utility automatically displays the first OPEN-x FMT volume (in
alphanumeric order) in the VOLSER field. If this is not the desired volume,
select the desired volume from the drop-down list of volsers. If ALC could not
find any OPEN-x FMT volumes, ALC displays the FX format disk not found
message.
4. Enter the name of the dataset being allocated in the Dataset field (maximum
forty-four characters: A-Z, 0-9, @, #, ., \). Do not use any spaces or symbols
other than @, #, ., and \.
5. Enter or select the size of the new dataset (number of cylinders, number of
tracks) in the Cylinder and Track fields. The file size will be (# of cyl) + (#
of tracks). The Max. button enters the maximum size for the new dataset in
the Cylinder and Track fields based on the available capacity. The
Available Capacity box displays the free space on the specified volume, so
that you can select the appropriate size for the new dataset.
6. Enter or select the record format in the Record format field: F, FB, V, or VB.
7. Enter or select the record length in the Record length field:
– When record format = F, record length = block length.
– When record format = FB, record length = block length ÷ N (N = integer).
