Q21. Which four activities are part of evaluating the tape application workloads supported by an SL8500?
A. dedicating rails to separate workloads
B. grouping tape drives by type function and quantity
C. managing cartridges for improved performance and archiving
D. minimizing elevator and pass-thru activities
E. mapping CAPS and pass-thru ports to partitions
Answer: A,B,D
Explanation: A:Dedicating rails—separating workloads to specific rails
Note:
Assign each workload its own tape drives, data tapes, scratch tapes, and free cells.
Dedicating separate resources to each workload and configuring these resources on as few LSMs as possible decreases pass thru activity, minimizes the time to mount tapes, and maximizes library throughput.
B: Grouping tape drives—locating them by function and drive type, with enough drives to support the workload
Note:Application-specific requirements may separate drive-types.
Example: placing T9840 access-centric tape drives on one rail, and T10000 capacity-centric tape drives on another.
C:Managing cartridges—moving inactive cartridges to archival LSMs or ejecting them. Maintaining free cells on each rail so cartridges can “float” there on a dismount.
D:Minimizing elevator and pass-thru port activity—enabling float and using CAPs intelligently.
Note:Do not try to distribute tape drives across all four rails is usually as this can increase pass- thru activity by the elevator and decrease overall performance of the library.

Q22. Nonlabeled cartridges are NOT supported in SL8500 libraries. If a cartridge is found without a label, it is:
A. reported by the SLC
B. exported
C. left alone and flagged
D. marked as a scratch tape
Answer: C
Explanation: The HSC and ACSLS host software applications do not support unlabeled cartridges and will not allow them to be entered through the CAP. If you place an unlabeled cartridge in a CAP, the host leaves it there and you must remove it from the CAP. If you place an unlabeled cartridge into a storage cell manually, the Robot leaves it there during a hardware audit and does not attempt to place another cartridge into the slot. During an ACSLS or HSC audit, however, the host moves the cartridge to the CAP for ejection from the library. The library controller will not allow you to mount an unlabeled or unknown type cartridge into any tape drive.

Q23. Partitioning allows the SL3000 library to be divided for use by multiple .
A. Power Supplies
B. Storage Cells
C. Hosts
D. Drives
Answer: C
Explanation: Library resources (cells, drives, and CAPs) are allocated to a partition for exclusive use by that partition. Storage cells, CAPs, and tape drives allocated to a partition can be used only by the hosts assigned to that partition.
Storage cells, CAPs, and drives not allocated to, reserved for or associated with any partition cannot be accessed by any hosts.

Q24. Which two conversions are possible using a Small Form-Factor Pluggable (SFP) module?
A. short wave to long wave
B. fiber channel to FICON
C. T10000A to T10000B
D. single port to dual port
Answer: A,B
Explanation: B: SFP transceivers are designed to support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards.
Q25. Which four options list the correct library scalability?
A. SL8500: library: 1000 to 10,000 Slots and up to 64 drives; Complex: Up to 100,000 Slots and 640 drives
B. SL500: 30 to 575 Slots and up to 18 drives
C. SL3000: 200 to 3000 Slots and up to 56 drives
D. SL24: Up to 24 Slots and either 1 full height or 1 to 2 half height drives
E. SL48: Up to 48 Slots and up to 2 full height or 4 half-height drives
Answer: B,C,D,E
Explanation: B: SL500 Maximum Number of Cartridge Slots: 575 Maximum Number of Tape Drives: 18 C:SL3000 Maximum Number of Cartridge Slots: 5925 Maximum Number of Tape Drives: 56
D: SL24
Maximum Number of Cartridge Slots: 24 Maximum Number of Tape Drives:One full height or two half-height E:SL48
Maximum Number of Cartridge Slots: 48 Maximum Number of Tape Drives:Two full height or four half-height

Q26. A StorageTek T1000B drive can be licensed and enrolled in the Oracle Key Manager (OKM) using which two tools?
A. VOP
B. OKM
C. ACSLS
D. VSM
E. SLC
Answer: A,E
Explanation: A: Virtual Operator Panelcan be use for enrollment.
E: When a customer purchases a hardware activation key to use more physical storage an encrypted key file is sent through e-mail. The file is then loaded into the library using the Storage Library Console (SLC).

Q27. How would you generate a list of the EHY100-WHY299 tapes in the LSM?
A. Log in as acssa, issue a “query vol all”, and then a “grep WHY100-299”
B. Log in as acssa, issue a “volrpt –zs”, and then a “grep why1”
C. Log in as acssa, enter a “volrpt –v why”, qand then a “grep WHY100-WHY299”
D. Log in as acssa and issue a “volrpt-v WHY100-WHY299”
Answer: D
Explanation: The volrpt utility creates a volume report.
restricts the report to the specified volumes (or volume ranges). You can specify a single vol_id, a list of vol_ids separated by blanks, or a volume range indicated by vol_id-vol_id.
Use the volrpt utility to create a report of library cartridges, including their physical location, history, attributes, and use.
Q28. Which statement best describes physical partitioning in StorageTek tape libraries?
A. A subset or portion of an entire library that presents itself to a host client as an independent library. Slots and tape drives included in one partition cannot be seen by another partition.
B. A subset or portion of an entire library that presents itself to a host client as a library partition. Slots and tope drives Included in one partition cannot be shared by another partition.
C. A subset or portion of an entire library that presents itself to a host client as an independent library. Slots included in one partition cannot be seen by another partition, whereas drives and CAPs can be shared by the entire library.
D. A subset or portion of an entire library that presents itself to a host client as a library partition. Cartridges included in one partition cannot be shared by another partition, whereas slots and tape drives can be shared across multiple partitions.
Answer: A
Explanation: A subset or portion of an entire library that presents itself to a host client as an independent library. Slots and tape drives included in one partition cannot be seen by another partition. CAPs cannot be shared.

Answer: A,B,C
Explanation: Vop has three basic functions:
* monitor drive status (B)

Q30. Using ACSLS, how would you delete a tape pool?
A. Set scr off and delete the pool
B. Remove all data tapes and delete the pool
C. Delete pool 0 and all empty pools will delete automatically
D. Remove all volumes from the pool and then delete it
Answer: A
Explanation: Use the delete pool command to delete empty scratch pools. If a pool contains scratch cartridges, you must reassign these cartridges to another pool before deleting the first pool. If a scratch cartridge is mounted, it becomes a data cartridge but remains in its scratch pool. Use the set scratch off command to reassign the data cartridge to the common pool.
