Write Protect
A write operation has been attempted on an LTO data cartridge that has write protection enabled. If you want to write to the LTO data cartridge, then unload the LTO cartridge (making sure the tape is unmounted from the OS) and disable write protection, move the red switch so the graphic lock sign is no longer visible.
If the red switch is not covering the hole, but the drive is still reporting the error P, please submit a support [ticket].
If you have any questions please submit a [support ticket]
