Things You Should Avoid Doing - IBM TotalStorage 3494 Tape Library Operator's Manual

Things You Should Avoid Doing

This section contains a list of actions you should avoid when operating a 3494
Tape Library but whose consequences are less serious than those in the preceding
list. Failure to follow these recommendations may still cause significant
performance degradation:
v Avoid leaving the convenience I/O station door open. After several minutes this
results in an operator intervention being sent to the host indicating that the
convenience I/O station door is open.
v Avoid running with the 3494 Tape Library completely full. Running with a full
3494 Tape Library makes it impossible to insert any more cartridges. It also
causes cartridges to be left in the I/O stations (convenience and high-capacity).
It may also hinder recovery of misplaced or inaccessible cartridges, which would
have to be recovered through the error recovery cell one at a time.
v Avoid running large database searches (for instance, searching for all volsers in
the 3494 Tape Library) from the Database window while the system is busy. This
can tie up the database and cause performance degradation.
v Avoid opening the enclosure doors without first pausing the cartridge accessors.
v Avoid any continuous action which causes a window to continuously use the
Library Manager hard drive.
