Error description
The Tivoli Storage Manager server has problems sending a LUN reset to a SCSI tape driver. The LUN reset should work for a SCSI tape device which is configured by the Tivoli Storage Manager tape device driver or the IBM tape driver with install_exclusive.exe without -p option (without Persistent Reserve feature enabled). The LUN reset is not suitable to reset a tape drive which is configured by the IBM tape driver with the Persistent Reserve feature enabled. This occur under the following conditions: - A tape drive is connected to a SAN. - Two host systems are connected to the same SAN. - One of these two host systems must be a Windows platform - For the Windows platform, this tape drive is configured by the Tivoli Storage Manage kernel device driver or is configured by the IBM tape driver with install_exclusive.exe with -p installation.
