User manual QUANTUM SCALAR 10K 300A.00007 RELEASE NOTES 04-2005

[. . . ] The library assigns a logical serial number to a 3592-J1A tape drive in a specific location. This is not the same serial number as the one that the manufacturer assigns to the physical tape drive itself. If a 3592-J1A tape drive is replaced by another 3592-J1A tape drive in the same library location, the logical serial number remains the same. From the host's perspective, the replacement drive is the same as the original one. [. . . ] When a TapeAlert occurs to indicate that an LTO tape drive needs to be replaced, the library issues a SAC 96. All other TapeAlerts cause the library to issue SAC ED messages, which appear in the Command and Error logs. Some SAC EDs also generate operator intervention messages, which are displayed on the Operator Panel. Both SAC 9C and SAC ED are new for this release. · Weekly retry statistics added to Command and Error logs A new section in the Command and Error logs provides weekly statistics about retry activity in the library. · Verification Tests The library now provides a series of verification tests to confirm correct library installation. ADIC service personnel can run the verification tests from the Operator Panel. The Verification Test Log provides the results of individual verification tests. · Automatic calibration The library will automatically calibrate (home) the accessor assembly with gripper and the Tower Modules (TMs). · Powering on a tape drive while varied off A tape drive that is varied off can now be activated (power turned on) for servicing purposes. 2 © April 2005, ADIC · Last SAC message stored before power cycle The library now stores the last-occurring SAC and error code in non-volatile RAM (NVRAM). Upon request by the Remote Management Unit (RMU), the library sends the stored SAC and error code to the RMU. Compatibility Matrix See the following table for information about drive and auxiliary firmware compatibility with Scalar 10K Version 300A. 00007. This information is current as of this product release. For the most current list of compatible firmware, contact the ADIC Technical Assistance Center (ATAC). Table 1 Drive and Auxiliary Firmware Compatibility Matrix Component RMU Scalar DLC AMC SNC SNC 3000 SNC 5100 Drive Types LTO-1 LTO-2 LTO-3 AIT-2 AIT-3 DLT-8000 SDLT 220 SDLT 320 3590 E1A / H1A / B1A 3592-J1A 4561 (SCSI, FC) 53Y2 (SCSI, FC) 53S0 0200_CY10 0207_1002 V80 V82 V82 DOIF_26E D310_529 The library assigns 12-character logical serial numbers to 3592-J1A tape drives. If you use IBM Tivoli® Storage Manager (TSM), install a version of the TSM device driver that is later than maintenance release 5. 2. 4. 4 (for TSM 5. 2) or later than 5. 3. 1. 1 (for TSM 5. 3) to ensure that TSM can properly identify 3592-J1A tape drives according to their 12-character logical serial numbers. 3. 43. 18 4. 45. 16 192A. 00001 2. 5 + SP2 4. 3 Firmware Version Note © April 2005, ADIC 3 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. As a result, the library cannot teach the drive. When a Teach Current operation is performed for a DM, a drive teach failure can return an incorrect bay number to the Operator Panel. When using a data tape instead of a FUP tape to update a list of drives, the library correctly posts a "BAD FIRMWARE MEDIA" operator intervention message, but continues to the next drive in the list. The operation should fail and not continue. After cleaning cartridges are ejected from drives, the View dialog (Main Menu Setup Cleaning View) continues to indicate a Valid status for the first cleaning cartridge rather than clearing the status. Workaround Manually adjust the vertical placement of the 3590 tape drive or the front bezel until the library can successfully teach the drive. 40518 Physically inspect the drive bay that the failure indicated or possibly the bay that is located immediately before. The bay that is identified by the failure might not exist. [. . . ] Resources were blocked too long or indefinitely when I/E station actions occurred and when the RMU was used to vary drives online or offline. Serial communications were lost between the Drive Control (LDC) card and LTO drives, which caused the library to issue SAC 96 error messages to the Operator Panel and required a re-sync recovery. Now, lost serial communications cause automatic drive reconfigurations with SAC 96 errors being issued when reconfigurations fail. The last-occurring SAC and error code needs to be stored in non-volatile RAM (NVRAM) before power cycle occurs. [. . . ]
