Robot Diagnostic Moves
Note – This feature is available starting with SL500 firmware version 1026 and
SL Console version 2.40.
Diagnostic moves are used to monitor or diagnose a problem with a HandBot. The
move can be performed with or without cartridges.
Successful diagnostic moves do not rearrange the cartridges in the storage cells;
cartridges are returned to their original locations after the diagnostic move is
completed. However, some diagnostic move failures can cause cartridges to be left in
new locations.
A diagnostic move involves the following elements:
■
Target Address Range
■
Pool Address Range
■
Move Access Order
Target Address Range
The target address range defines the location parameters in a library within which the
get operation is performed in a diagnostic move. There are two types of access orders
for a target address:
■
“Sequential Access Order” on page 255
■
“Random Access Order” on page 255
Following are valid target address types:
■
Storage cells—Reserves all the storage locations as the target range
■
CAP—Reserves the cells in the as the target/pool range.
■
Drive and Storage cells—Reserves all the drives and storage cells as the target/pool
range.
■
System cells—Reserves the locations (reserved cells) containing the cleaning or
diagnostic cartridges as the target/pool range.
■
All—Reserves all storage cells, CAP and Drives as target/pool range.
Note – Selecting the Storage, CAP, drive, system, or All option does reserve all the
associated locations as the target range. However, only the location currently being
accessed by the HandBot for a get/put operation is unavailable to the host.
