User manual QUANTUM SCALAR 10K 310A.00002 RELEASE NOTES 06-2006

[. . . ] Once you enable the logical serial number feature, the manufacturer's serial number is no longer visible and the logical serial number is listed in the library logs, along with the manufacturer's serial number. IBM LTO-1 SCSI / FC, IBM LTO-2 SCSI / FC, IBM LTO-3 SCSI / FC, IBM LTO-3 4Gb FC, IBM 3592-J1A/TS1120. Drives that currently support this feature are: · · IBM TS1120 Drive Support The Scalar 10K library now supports the TS1120 drive. Refer to the Scalar 10K SCSI Reference Guide for information on drive element types. · WORM Support The Scalar 10K library supports WORM (write once, read many) technology in LTO-3 tape drives. WORM allows non-erasable data to be written once and provides extra data security by prohibiting accidental data erasure. [. . . ] After being captured, the FSCs are logged by the Library SCSI Controller (LSC) and are visible through the Library Command Log. Send the tape's VOLSER to the drive so when drive information is extracted it will contain a meaningful VOLSER that a customer can locate. (LTO & 3592 drive types are the only ones that support this feature so far. ) Tape Alert (TA) information more accurately reflects the condition of the drive. When large amounts of data were passed to the host, high SCSI activity would cause a Service Action Code (SAC) A3 for the gripper. For example, the SAC A3 occurred when the library performed multiple tasks, such as teach the IE and attempting to send data to the host over SCSI bus. The Library SCSI Controller (LSC) became so busy it could not service responses to the gripper command and would post a SAC A3 on the operator panel. Now if the SCSI bus is busy performing large data transfers, the other operations will wait for the data transfer to complete before issuing additional commands to the gripper. When a drive was being varied online, the cartridges that were in other drives would be set to the default media type. When the cartridges that were in other drives were moved back to storage slots, the library could no longer place them back into a drive if their new media type was not the correct type for the drive. Now when a drive is being varied on line, the library will not set the media type of cartridges that are in other drives. CR 42442 N/A CR 43221 CR 47537 N/A SR 420534 CR 51700 SR 461614 4 © June 2006, ADIC Change Request Number CR 52796 Service Request Number SR 465006 Description Touch teach failures should not post operator panel messages for IE stations. The library notes the failure in the library log, but no longer posts the touch teach failure to the operator panel, because the library does not fail and the IE magazines can still be used to import and export the media. Version 303A. 00001 CR 49088 SR 448174 Opening and closing the I/E door during the vaulting operation causes the operation to fail If the I/E door is opened and closed while Netbackup is vaulting to the I/E station, Netbackup vaulting operations can fail. If the vaulting operations fail, the operator must restart the vaulting job. Opening and closing the I/E door while the vaulting operation is in process is considered to be operator error. To avoid causing this failure during the vaulting process: · Open the I/E doors only when prompted to do so by Netbackup. · Open all of the I/E doors at the same time and remove all cartridges. · Close all of the I/E doors at the same time and make sure the lock light is on all I/E station doors that were closed prior to telling Netbackup to proceed with the vaulting operation. Library no longer returns the full status on an open I/E door Formerly, when the I/E doors were opened fully loaded with cartridges, and the cartridges were removed and the I/E doors closed, Netbackup would attempt to move the cartridges back into the library. The vaulting process would fail and the library would return a 02/53/02 service action code. The vaulting process failed because the library returns an exception status for all cells when the I/E door is open. [. . . ] Version 301A. 00002 CR 43807 SR 404660 Fibre channel topology selection for sleds does not correctly affect the configuration of the drive. Instead, the drive is always configured to operate in AUTO topology mode, independent of OP panel choice. 6 © June 2006, ADIC Known Issues This release of Scalar 10K firmware has the following known issues:. Change Request Number 33359 Service Request Number 282830 Description On occasion, the vertical mounting of a 3590 tape drive might be higher than the vertical window expected by the library firmware to successfully scan for the drive fiducial. When a Teach Current operation is performed for a DM, a drive teach failure can return an incorrect bay number to the Operator Panel. [. . . ]
