PACKSCAN Command Updating VTOC Entries (TSIDVUT)
6-56 BIM-EPIC Installation and System Guide
PACKSCAN Command
Use the PACKSCAN command to display and update VTOC entries from the operator
console. You can perform any TSIDVUT update function, plus ADD, an additional function
available only with the PACKSCAN command. ADD reactivates VTOC entries that have
been marked as “deleted". Only datasets with less than four extents per volume can be
reactivated.
When PACKSCAN is executed, TSIDVUT issues messages on the operator console and wait
for operator responses. PACKSCAN processing is described below. See Messages and
Codes for descriptions of the messages issued.
PACKSCAN
When you issue the PACKSCAN command, TSIDVUT issues message EP766. At this stage
you identify the type of search you want (dataset or volid), or request the ADD function, or
exit PACKSCAN.
Respond with any of the following:
•
SEARCH='dsn' (to display the requested dataset)
•
SEARCH='dsn.ALL' (to display all versions of the requested dataset)
• volid (to display all the datasets on the volume)
• ADD (to add a new VTOC entry)
•
END (to exit PACKSCAN)
Both SEARCH='dsn' and SEARCH='dsn.ALL' cause message EP767 to be issued. Respond
with any of the following:
• volid (to identify the disk volume to search)
•
NEWFILE (to request a new PACKSCAN function)
•
END (to exit PACKSCAN)
If you entered a volid, see below. If you entered "NEWFILE", message EP766 will be issued
(see above).
When you enter a volid, TSIDVUT displays the VTOC entries from that volume. If you
entered SEARCH='dsn' previously, TSIDVUT searches only for the dataset you requested. If
you entered SEARCH='dsn.ALL' previously, TSIDVUT searches for all matching datasets.
If there is no match for your dataset name or there are no VTOC entries on this volume,
TSIDVUT issues EP767. See above for responses.
