Important Information - LTO-9 Media

LTO-9 media calibration is a new requirement for LTO-9 media. Calibration is a one-time requirement for new cartridges prior to first-time read/write operations; it is not a requirement for older generations including LTO-8. Due to continued LTO innovation, with LTO-9 there is an increased number of tracks used to write data on tape that requires greater precision. Media optimization creates a referenced calibration for each cartridge that enables the tape drive’s intelligent alignment to optimize data placement and enhances LTO tape long-term media durability.

For a more detailed description of the different possible scenarios with LTO-9, please reach out to your Quantum representative or solutions architect.

 

Q: Is there a difference between the terms, “optimization”, “initialization” and“calibration”, in reference to LTO-9 media?

A: No. Quantum chose to use “calibration” to describe this one-time LTO9 media

event.

 

Q: What is Media Calibration?

A: Media calibration has been implemented in LTO-9 technology to optimize data placement to each LTO-9 cartridge characteristics. Brand new LTO-9 media requires a one-time step initialization prior to commencing read/write operations. LTO-9 media calibration enhances LTO tape long-term media durability.

 

Q: Once the LTO-9 media cartridge has been calibrated within the recommended environmental range, does it need to be re-calibrated when it is moved to a separate drive, separate library, separate data center or environment?

A: No, the LTO-9 calibration process is only required on the first load of a new and unused LTO-9 media, subsequent loads in any LTO-9 drive do not require calibration.

 

Q: Will LTO-8 media require calibration on first load to an LTO-9 tape drive?

A: No. Media calibration is required only on brand new LTO-9 media.

 

Q: How much time does the calibration add to the first-time load of a brand new cartridge?

A: Media calibration averages between 35 to 52 minutes per first load of a cartridge to a tape drive, could take up to 2 hours to complete the calibration.

 

Q: Why does the LTO-9 media require calibration?

A. Higher track densities (TPI) and longer tapes using thinner polymer base substrates in LTO-9 media achieve double digit Areal Densities and more than 21K TPI track density. A new tape calibration algorithm was introduced, ensuring data durability, compatibility and allowing for complex interchange requirements over the specified environmental conditions. The length of calibration is mainly for media optimum characterization and will vary based on these factors. This initial calibration, also, enables the tape drive’s intelligent alignment to optimize data placement.

 

Q: Does LTO-9 media calibration need to be performed in destination site?

A: It is recommended, due to environmental requirements, that calibration should be performed in the final installation destination where the drives and media are to be used to ensure optimized acclimation within recommended environmental range on Quantum product data sheets.

 

Q: Can the customer disable media calibration?

A: No, the one-time calibration cannot be disabled. In order for the tape to perform, it must be calibrated before first time use and one time only.

 

Q: Can I use uncalibrated LTO-9 media for IVT?

A: No, do not use uncalibrated LTO-9 media for IVT. The LTO-9 media needs to be calibrated before use with IVT.

 

Q: Can I use an Extended Data Life Management (EDLM) drive to calibrate new LTO-9 media?

A: No, the EDLM scan engine will recognize that the media is new and does not contain data and just unload it again without loading it. This mechanism will prevent the media from getting calibrated in an EDLM drive.

 

Q: Can I recalibrate an LTO-9 media cartridge?

A: Yes. The Format command with specific field settings will reinitiate calibration. However, regardless of recalibration, any Format command will result in loss of all existing data on the tape.

Tasks

Configuration

Administrators can view and modify certain tape drive parameters. You can set the loop IDs, topology connection mode, and interface speed for a Fibre-attached tape drive.

You can set port access but not set additional parameters for LTO-9 and above SAS tape drives. A SAS tape drive’s SAS address is automatically and uniquely generated based on a unique World Wide Node Name (WWNN) that the drive receives when it is configured.

If the affected partition is online, it will be taken offline before the parameters are set, and brought back online after they are set. Drives not assigned to a partition or drives in EDLM partitions are not eligible for configuration.

  1. From the Navigation panel, select Drives.
  2. In the North Panel, select the check box next to the drive(s) you want to modify.

The Access Group feature allows you to add a drive to an access group. A host access group is composed of at least one host and one drive. Each host in the access group can send read/write commands to the drives in the group, and can send move commands to the partitions in the group.

While a host can only be in one access group, drives can be in multiple access groups.

Note: Host access groups are only available on HP LTO-5 and LTO-6 drives.

Caution: If path failover is configured for a partition you are planning to add to an access group, make sure you assign both the control path drive and the control path failover drive to this host access group. If you do not, then if the control path fails over, you will lose host access to the partition.

Maintenance

Library tape drives require occasional cleaning. Cleaning cartridges are used to remove accumulated residue from each tape drive’s read/write head.

To assign library cleaning cartridges to cleaning slots, refer to Library Cleaning Slots.

The library supports two methods for cleaning tape drives with cleaning cartridges: Auto Clean and Manual.

Auto Clean — Configuring a partition for cleaning enables Auto Clean. Cleaning cartridges are stored in the designated cleaning slots. When a tape drive needs cleaning, it notifies the library, and the library automatically cleans the tape drive using a cleaning cartridge loaded in a cleaning slot. Automatic cleaning is integrated into routine library operations. The host application requests the library to move a tape cartridge. If the tape drive performing the operation needs cleaning, the library will perform the move operation and then automatically clean the tape drive with a cleaning cartridge before informing the host application that the move operation is complete.

When a cleaning cartridge has expired, a RAS ticket informs the user to export the expired tape from the library. If more cleaning cartridges are present, the next cleaning cartridge will be used for the next cleaning request. If no more cleaning cartridges are available, a RAS ticket will inform the user that the tape drive needs cleaning and that a cleaning tape needs to be imported.

Only administrators can configure cleaning slots, thus enabling Auto Clean. When Auto Clean is enabled, the library allows you to import and export cleaning media through the I/E area.

Note: Cleaning slots are not visible to the host application. To choose host-based cleaning, do not configure any cleaning slots, and configure your host application to manage cleaning tape drives. Configuring cleaning slots on the library may affect the host application. See your host application documentation for information.

Manual Cleaning — When a tape drive needs cleaning, it notifies the library. If the library’s Auto Clean feature is not enabled (no cleaning slots have been configured), the library generates a RAS ticket informing the user that the tape drive needs cleaning. Administrators can clean tape drives manually at any time, using commands on the operator panel or Web client

The preferred method of labeling a cleaning cartridge is to have CLN or CLNU as the prefix on the label. Any cartridge detected with a CLN or CLNU prefix will be considered a universal cleaning cartridge, regardless of any media identification extension. Cartridges containing a media identification of C1, C2, C3, C4, C5, and CU will be considered cleaning cartridges and will be tracked and treated as if the media label contained the prefix CLN or CLNU.

  1. From the Navigation panel, select Drives.
  2. In the North Panel, select the check box next to the drive(s) you want to clean.
  3. If they aren't already offline, take them offline now by clicking Offline.

  4. In the Operations panel, click Cleaning.

Actions

There are two tape drive modes:

  • Online — Tape drive is available for medium changer operations as instructed by a SCSI host. This is the normal operating mode for the tape drive.
  • Offline — The drive not available is not available for medium changer operations as instructed by a SCSI host. An offline drive is still available for WebGUI initiated commands.

Some operations require that the tape drive be offline. You can take a tape drive offline rather than the entire library or partition so as to minimize disruption of library operations.

Note: Using the library to change tape drive mode may affect the host application. See your host application documentation for more information.

  1. From the Navigation panel, select Drives.
  2. In the North Panel, select the check box next to the drive(s) you want to change status.
  3. In the Operations panel, click Online or Offline.

There are instances when a specific drive needs to be identified at the physical library. In these cases, using the Identify feature causes the LEDs on the back of the drive to blink rapidly so that the drive can be found quickly. After a designated amount of time, the LEDs go back to normal operation.

When you click Identify On, a message appears that informs you that you can now identify the drive by the rapidly blinking blue LED on the back of it. After you find the drive, click Identify Off to stop the rapid blinking.

  1. From the Navigation panel, select Drives.
  2. In the North Panel, select the check box next to the drive(s) you want to identify.
