Cleaning; Resetting Drives In A Library - HP HPE StoreEver LTO-8 Ultrium Tape Technical Reference Manual

Cleaning

When the drive needs cleaning:
• The orange 'Clean' LED on the front of the tape drive will flash. Only insert a cleaning cartridge into the
tape drive when the LED flashes.
• The TapeAlert feature for the drive will send a message to your backup application.
• In a library or tape array, the drive tells the automation controller over the ADI interface that a cleaning
tape must be used.
See the Automation interface for details.
CAUTION:
Use only LTO Ultrium Universal cleaning cartridges C7978A (Orange) with HPE LTO Ultrium tape
drives. Other format cleaning cartridges will not load and run. Use of HPE cleaning media will
ensure that your tape drive is fully protected. Do not use swabs or other means of cleaning the
heads.
To clean the heads:
Procedure
1. Insert a cleaning cartridge into the drive. The tape drive automatically loads the cartridge and cleans
the heads.
If the cleaning cartridge ejects or returns to the ready-to-eject position immediately with the Tape Error
LED on, it has expired or it is not an LTO Ultrium cleaning cartridge (or is an older unsupported LTO
Ultrium cleaning cartridge). In this case, discard the cleaning cartridge and repeat the operation with a
new one.
The cleaning cycle can take up to 5 minutes. During the cycle, the orange 'Clean' LED will be on
steadily and the green 'Ready' LED will flash. When it has finished, the drive ejects the cartridge or
returns the cartridge to the ready-to-eject position.
2. Remove the cleaning cartridge from the drive.

Resetting drives in a library

The tape drive can be reset by the automation controller by cycling power to the drive.
Resetting the drive will interrupt the interface between the drive and host, and a reset may result in no
End of Data mark being written. As a result, HPE recommends that a reset is not performed unless all
other recovery methods have failed. Certain automation commands (Load, Unload, Set Drive
Configuration, Reset, and Set Baud Rate) can be queued behind outstanding SCSI commands giving the
impression that the drive has stopped responding over ADI.
In response to a reset, the drive will behave as at power-up.
An FCP reset will not affect the automation interface.
Following an upgrade of the drive firmware the drive will be reset as if it had been powered up.
