Each time the library is powered on, it performs a sequence of activities. 

During its power-on sequence, the library:



Performs a power-on self-test (POST)



Runs self-diagnostics



Establishes communication with the tape drive(s)



Verifies the SCSI IDs



Performs a cartridge inventory

The time required for the power-on sequence is measured from the time 

power is applied until the library indicates ready status.

The library’s power-on sequence time is approximately10 seconds when the 

library contains 20 cartridges with or without bar code labels.

An application can issue a command to the library to check all cells for 

cartridges and scan bar code labels. After checking the cells, the library 

updates its cartridge inventory.

The average cartridge inventory time is approximately:



100 seconds when the library contains 20 cartridges with bar code labels.



1200 seconds when the library contains 20 cartridges without bar code 

labels.

Whenever a cartridge is inserted or removed through the I/E port, the library 

performs a cartridge inventory on the affected cell.

The average time for an individual cartridge cell inventory is:



15 seconds when the cartridge has a bar code label.



50 seconds when the cartridge does not have a bar code label.

Move complete time is the time it takes the library to remove a cartridge from a 

tape drive, return it to its cell, and load the new cartridge into the tape drive.

Move complete time is measured from the time the library receives the move 

command to the time the library returns status to the initiator indicating that 

the move is complete. The average move complete time is approximately 

150 seconds. Worst case time to complete this command is 10 minutes.
