User manual QUANTUM SCALAR 10K 313A.00001 RELEASE NOTES 01-2007

[. . . ] · Note: When enabling or disabling the logical serial number, the library must be power cycled before the change is reflected in the library. 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. Drives that currently support this feature are: · · IBM LTO-1 SCSI / FC, IBM LTO-2 SCSI / FC, IBM LTO-3 SCSI / FC, IBM LTO-3 4Gb FC, IBM 3592-J1A/TS1120. 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. [. . . ] The gripper test should be run at boot, and the results printed in the log so the health of the gripper can be evaluated. The problem was caused by code sending a request for an extended status to the drive, which is only supported in SDLT drives. Version 304A. 00001 57293 CR 30354 N/A Capture and log False Symptom Codes (FSCs) from drives. 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. © January 2007, Quantum Corporation CR 42442 N/A CR 43221 CR 47537 N/A SR 420534 4 Change Request Number CR 51700 Service Request Number SR 461614 Description 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. 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. CR 52796 SR 465006 © January 2007, Quantum Corporation 5 Change Request Number Service Request Number Description 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. [. . . ] While the S10K performed the teach and inventory for the I/E station 2, the S10K allowed you to open and close I/E stations 1, 3, 4, because the RES data returned to the host indicated that these other I/E stations were accessible. However, if the host then issued a move to the cells in one of these I/E stations, the move would fail. With release 302A, all other I/E stations are locked to the host while the S10K teaches and inventories the I/E station that was just opened and closed. Version 301A. 00002 CR 43807 SR 404660 Fibre channel topology selection for sleds does not correctly affect the configuration of the drive. [. . . ]
