Dell PowerVault TL4000 - Manual (Page 162)

2. The library code must be updated first, unless noted otherwise. This action
supports any changes that are introduced in the library code for that drive, or
any changes that are made to the drive for that release.
3. These firmware updates are intended to increase overall reliability, improve
tape handling, reduce the possibility of data errors, and enhance diagnostic
capabilities.
Note: Library firmware and tape drive firmware are verified and released together.
When you are updating to the latest firmware, verify that all installed
components such as tape drive, and library are at the latest levels noted on
the Support website. Mixing different levels of library and tape drive
firmware is not supported and might cause unpredictable results.
This page displays the current library and drive firmware versions. Firmware is
downloaded to the host, then uploaded to the drive or library.
Click Browse... to choose the firmware file you downloaded from the website for
the library or drive you want to update. (You can update only one device at a
time). Be sure that you choose the correct firmware for the library or drive type.
Click Update to initiate the file transfer and firmware update.
Note: During the update, no host drive action is possible. The drive update takes
approximately 5 minutes. The system status panel (in the right of the
browser window) changes from "update" to "ready".
If incompatible firmware is transferred to the library or drive the Update function
terminates with a message that indicates incompatible firmware. If the library has
a BCR (barcode reader) that requires 9.00 or greater firmware, the Update function
terminates with a message that indicates the library requires firmware 9.00 or
higher.
To ensure that the drive is updated with the correct firmware, refer to the drive
identification information provided in the Upgrade Library Firmware banner.
Ensure that the drive firmware is for the correct drive type (Full Height, Half
Height), correct protocol (SCSI, SAS, Fibre Channel), and correct version (V2).
Drive code for V2 drives is not compatible with drives that are not V2.
